1. Introduction
1.1. Background
Energy consumption in Indonesia is expected to increase because of population and
economic growth. The presidential decree of 2006 formulated by the government of
Indonesia has aimed at reducing petroleum dependency and promoting natural gas
use in the context of diversification of energy sources.
However Indonesia doesn’t have sufficient pipelines for transport of natural gas.
Location of gas pipelines is limited to Java and Sumatra islands. Also Indonesia has
many islands. Hence infrastructure for transporting natural gas to remote islands is
very limited. Consequently, there are many diesel generators in power plants, factories
and smelters in remote areas. For example, the number of diesel power generators in
remote areas in Indonesia operated by PLN is 4,500 units with total capacity of 2,500
MW.
The government of Indonesia has recently introduced a new policy for supplying LNG
to domestic market instead of exporting. This policy change will result in the supply of
natural gas for domestic market through LNG and increase quota of natural gas from
the production for domestic market. Eventually, the decentralized distribution system
of LNG to remote island areas would be developed. For example, PT Pertagas Niaga
and the association of natural gas distributors of PT Pertagas Niaga is conducting
feasibility study to transport LNG by ISO containers from Bontang to locations of end
users. Considering high dependency of remote island areas on diesel fuel, there is a
very big potential for introducing mini-LNG distribution system for remote areas. It
would lead to conversion of fuel from petroleum products to natural gas and
installation of cogeneration system using natural gas. Such applications of LNG would
result in reduction of fuel cost, energy saving and reduction of CO2 by considerable
amount.
In fact, Japan has been the largest LNG importer in the world. The natural gas from
LNG has been used for promoting energy saving and CO2 reduction by fuel conversion
since 1990s. Besides, Japan has severe terrain to not allow construction of gas
transport pipeline. There are, therefore, many satellite facilities like tanks and small
size vaporizers and equipments like ISO containers of LNG for transportation to
2
remote areas in Japan. Japan also has the know-how to achieve energy saving in end
users by using LNG.
1.2. Aim and objectives
In this study, Japanese consortium of Nomura Research Institute, Toyota Tsusho
Indonesia and Air water collaborates with PT Pertagas Niaga to introduce Japanese
knowhow and products on satellite transport of LNG as well as knowhow of energy
saving and fuel conversion by using LNG to Indonesia. We assume that potential users
of LNG are power plants operated by PLN and IPP, industrial parks, smelters and coal
mining companies located in remote areas.
This study also aims at identifying the project sites where we could conduct detailed
feasibility studies to clarify the technical issues and commission the facilities in 2016.
Besides, the study would promote technical information of mini LNG facilities and
equipments in Japan to Indonesian stakeholders. Finally, we aim to propose necessary
policy reforms to the government of Indonesia if required.

2. Methodology
2.1. Scope of the project
The entire value chain from the gas well to end users is shown as Figure 1. There are
several steps, but considering the stakeholders’ positioning, Japanese consortium
would focus on supporting distributors and providing facilities, equipments and related
services including onsite storage tanks and accessories and ISO containers. Japanese
consortium could also provide energy saving facilities and equipments like
co-generation plant, but that would be in the first step of the study. The position that
Japanese consortium would take would depend on the demand by Pertagas Niaga,
local distributors and potential end users. Therefore, the consortium, would not decide
its position in the value chain and look for every business opportunity in the beginning.

2.2. Scope of study
Given the above mentioned project scope, the scope of the study is also very flexible
based on demand of the Indonesian stakeholders. Initially, the scope of study, however,
has been set as below.
We have three research topics for this study. The first is a feasibility study on
mini-LNG transport and fuel conversion business in Indonesia. The second is proposal
of policy reform to promote mini-LNG transport and fuel conversion by using LNG in
Indonesia. Finally, we would promote know-how and technical knowledge of mini-LNG
transport facility and equipment in Indonesia.

2.3. Applicable technology
For transporting LNG in the domestic market, ISO containers, satellite facilities
including storage tank, evaporator, and mini-LNG tanker are assumed as technologies.
In this study, those technologies are assumed as applicable technologies.
2.3.1. ISO Containers
Two types of ISO containers, semi-frame 40ft container for trunk line and full-frame 30
ft containers for sub trunk line of transport are considered.ISO containers can not be
applied for local class III roads because of its limitation of width.

2.3.2. Satellite facilities
Satellite facilities prepare storage tank, vaporizer, piping system to reserve LNG for
buffering the demand and supply gap.
As contrary to the conventional LNG tank for receivable purpose, the satellite LNG
storage tanks don’t require very large land for development. Only 17000 mm x 24000
mm areas are required. This satellite facility can be easily developed in port, coal
mining area, power plant, big commercial buildings etc.

2.3.3. Mini LNG Tanker
Indonesia has many islands. Sea transport is, therefore, very important. In Japan,
mini-LNG tanker for 1,000-10,000 has been already manufactured by Kawasaki
Heavy Industry and has been operated by domestic shipping companies.

3. Results
3.1. Japanese experience
3.1.1. Import and transport of LNG in Japan
Import of LNG has increased constantly since 1988 in Japan. In 2013, the import was
three times of that in 1988, reaching to about 90 million ton. In particular, additional
20 million ton of LNG between 2011 and 2013 was imported because of suspension of
atomic power plants due to damage by severe earthquakes and Tsunami in 2011.

In order to import huge amount of LNG, many receivable tanks have been developed in
Japan. Figure 6 indicates the location of receivable tanks, including both primary and
secondary receivable tanks. They are scattered all over Japan, but most of them are
located on the Pacific belt area which is the most industrialized area in Japan. Those
tanks are developed not only by gas companies, but also by electricity power companies,
petroleum companies and steel manufactures.

It is normal to transport natural gas from these receivable tanks to pipelines in most
parts of the world. But Japan did not have adequate transport pipelines of natural gas
from receivable tanks to end users. Only Kanto, Kansai and Chubu regions had
enough pipeline connection between end users and receivable tanks. Consequently,
Japan had to develop the satellite transport network of LNG from receivable tanks to
end users.

Figure 8 shows the typical system of mini-LNG transport. Tank lorry and container
freight train can be used for LNG land transport between receivable tanks and
satellite facilities. From satellite facilities, the LNG is vaporized to natural gas by air
temperature or warm water temperature, and then vaporized natural gas is
transported to factories and building of end users by pipeline.
In Japan, ISO containers are also used for multimodal transport by railway service
and land transport service. ISO containers were previously used for sea transport
between Kanto and Hokkaido.
Once certain amount of demand of natural gas is created by using these satellite
transport equipments, transport pipeline would be developed for this route.

In case of Kanto region, Tokyo Gas transports LNG by lorries to satellite facilities for a
maximum of 200km distance from Negishi or Sodegaura. Interestingly, this area has
distribution pipeline network, but some of distribution pipeline cannot transport
enough amount of natural gas to the end users and in some cases, there is no trunk
transport pipeline developed near the end users. Hence the LNG satellite transport
system is required along with pipeline distribution network.

In another case, railway can transport LNG for more than 300km from Himeji to
Toyama or Niigata to Kanazawa. Railway can transport more than lorry transport. For
example the transport pipeline between Niigata and Toyama was constructed because
there was enough supply track record demonstrated by railway transport of LNG to
justify development of a pipeline to transport natural gas. Hence, the life span of
railway transport is not necessarily longer than lorry transport.

Mini LNG tanker can also be used for 2,500 m3 size of LNG transport apart from
lorries and railway. Japan has inland sea transport for LNG transport from receivable
LNG tank to satellite facilities. For example, Japan uses 2,500m3 – 3,500m3 size of
mini LNG tanker for LNG transport.
The typical case is observed between Sapporo and Hakodate as well as Kitakyushu
and Takamatsu. The Kitakyushu LNG terminal is the primary receivable LNG tank
from abroad. Shinju Maru is operated from Kitakyusyu to Takamatsu in Shikoku for
380km for 17 hours journey. Shikoku gas has developed the secondary receivable LNG
tank at Takamatsu. After unloading LNG from the mini-LNG tanker and charging
secondary receivable LNG tank, lorries come to take LNG for satellite transport to
Imabari in Ahime Prefecture for 145km, Kouchi in Kouchi prefecture for 130km and
Tokushima in Tokushima prefecture for 70km. There is very good road connection
between Takamatsu and those destinations. This is a typical multi-modal transport of
mini-LNG between sea transport and land transport in Japan.

3.1.2. LNG and cool heat of LNG use in Japan
Natural gas vaporized from LNG is normally used for city gas, but Japan also utilizes
several other features of LNG like cool heat of LNG. Figure 12 shows general process of
LNG vaporization to natural gas and use of natural gas. In LNG receivable tank, cool
heat of LNG is sometimes used for refrigerators and manufacturing liquid air line
nitrogen, oxygen and argon gas. In the vaporization process, heat gap between LNG
and natural gas can be utilized for binary power generation called as cool heat recovery
power plant. In the end, vaporized natural gas is used for cogeneration including power
and heat generation.
In Indonesia, business developers of mini-LNG transports can also develop these types
of by-product businesses. If the receivable tanks and satellite facilities are located in
remote areas where fishery and agriculture are prevalent, they must develop these
kinds of businesses.

3.1.2.2. Production of Liq. N2, O2 and Ar. from Air
Production of liquid air gas is also a typical bi-product industry in Japan. These gases
are recognized as industrial gas and their typical use is for wielding and for
manufacturing fluorescent lamps. Boiling points of those gases are slightly lower than
the temperature of LNG, but the cool heat from LNG enables to save energy for
separating those gases from air. The oldest plant was developed in 1971 and is more
than 40 years old and it has long track record of operation.

3.1.2.3. Production of Liq. CO2 gas and Dry ice from emission gas from oil
refineries in Japan
Production of CO2 and dry ice also use cool heat from LNG receivable tanks, but it
needs one more source of rich carbon dioxide air. This is why these plants have to be
located next to a refinery. The oldest plant for manufacturing CO2 liquid air and dry
ice was developed in 1980 and is 35 years old. This type of plant also has a good track
record.

3.1.2.4. Cool heat recovery power generation for captive use
Binary power generation system is also a typical plant in Japan. The oldest plant was
commissioned in 1979 and now we have 16 plants under operation in Japan. Three
types of technologies were introduced like rankine cycle, direct expansion system and
mixed fuel rankine cycle system. These power plants were mainly developed for
captive use to cover the electricity demand in LNG receivable tanks. Accordingly, this
technology is not for the bi-business of mini-LNG transport, but would be used for
saving energy of mini-LNG transport business.

3.1.2.5. Cogeneration system
Since 1987, Japan has installed a lot of cogeneration systems, and currently more than
14,000 units of cogeneration systems are working. The total capacity of those
cogeneration systems will almost reach 10,000 MW (10GW) in Japan.

3.2. Current situation in Indonesia
As mentioned in the previous chapter, the demand for energy in Indonesia is
increasing because of its population as well as economic growth. The government
would like to promote natural gas use to decrease the import of petroleum products
like diesel oil and decrease the subsidy for petroleum products from financial
perspective.
Indonesia has many islands and very less pipeline network. Hence, the government
wants to develop LNG transport infrastructure to resolve these severe conditions.
The natural gas consumption in Indonesia is gradually increasing after 2004, but the
production of natural gas has already peaked out (Figure 15). The energy demand
outlook suggests that the consumption of natural gas in 2035 will increase twice as
much as consumption level in 2010 (Figure 16). Considering the difference between
consumption areas and production areas of natural gas and the limitation of LNG
facilities in Indonesia, the government of Indonesia has to develop efficient transport
tools of natural gas in near future to supply energy.
Simultaneously, the government of Indonesia is cooperating with international society
to cope with global warming. Natural gas use is more eco-friendly than using coals and
diesel oils, in general, considering emission gas. In addition, the government will also
cope with the regulation reform of International Convention for the Prevention of
Pollution from Ships, 1973, as modified by the Protocol of 1978 (MARPOL 73/78) by
International Maritime Organization. Consequently the Ministry of Transport will
have to develop LNG bunkering facilities in international ports of Indonesia.

over Indonesia as shown in Figure 18. They have already developed road map for
preparation of mini-LNG transport and time-frame for development of loading
infrastructure for mini-LNG transport in Bontang as shown in Figure 19.
According to the roadmap, most of feasibility studies were conducted in 2014. In the
intermediate workshop held by Pertagas Niaga in December, Pertaga Niaga and its
association companies have already identified technical issues, but the big challenge
on middle size transport of LNG by sea transport to mining sites in Sangatta and
Berau area still remains. Hence, Japanese consortium has been requested by Pertagas
Niaga to cooperate for conducting joint feasibility study in the next phase.
In terms of the development of loading facilities, Pertagas Niaga only assumes barge
transport with ISO containers. Mini-LNG tanker, however, is necessary to satisfy the
demand of LNG in coal mining area. Pertagas Niaga and Japanese consortium
continue to discuss solutions to manage this gap.

3.3. Regulation(s) and policy(ies) related to the project
3.3.1. Technical regulation on min-LNG transpor faciliteis and equipments
In terms of LNG and natural gas provision for domestic market, some actions have
already been taken by the government of Indonesia. First, the Arun, which is originally
LNG exporting facility, would be converted to LNG import facility to provide natural
gas for north part of Sumatra. Second, Pertamina promotes the mini-LNG concept for
transport of LNG for domestic market in small scale using ISO containers and other
considerable equipments. Pertagas Niaga has been appointed for this concept and is
conducting several trials. Third, Ministry of Transport, Maritime division also shows
its interest, because the ministry has to follow the request of the international treaty,
International Convention for the Prevention of Pollution from Ships, 1973, as modified
by the Protocol of 1978 (MARPOL 73/78). In summary, there is no case to use
mini-LNG equipments and facilities right now, but demand can be considered to be
very high.
Despite this situation, there is no specific regulation and technical standard for
mini-LNG facilities and equipments in Indonesia.
The nodal agency of technical aspects of mini-LNG facilities and equipments is MIGAS
technical department. According to MIGAS technical department all equipments are,
in pricipal, allowed to be used when they follow international regulation or Japanese
regulation. Japanese regulations are sometimes very strict for Indonesian situation, so,
the government of Indonesia relaxes Japanese regulations in some cases and then
applies them for Indonesian market. The specification of each equipments and
faciliteies has to be shared with authorities in Indonesia to be examined. Once such an
examination is conducted, opeartors can use them more conviniently.
3.3.2. Safety regulation
In terms of labour safety regulation and guideline, it will be regulated by the Ministry
of Labour, but the actual operation manual in case of existing LNG export terminal is
developed by Pertamina. The ministry only regulates general matters and the ministry
always relies on specific entity to regulate technically specific matters. So currently,
Japanese consortium has to develop common understandings with Pertamina and
27
Pertagas Niaga on the safety regulation to handle mini-LNG facilities and equipments
in Indonesia.
On the other hand, another regulator of downstream natural gas business, BPH Migas,
has not been appointed for mini-LNG satellite distribution. BPH Migas is only in
charge of pipeline distribution, and in terms of pipeline distribution business, BPH
Migas is concerned with the safety issues. When the higher government, MIGAS,
appoints BPH Migas to control and supervise the mini-LNG satellite transport
business, then BPH Migas will develop regulations. Currently only Pertamina and
Pertagas Niaga are in charge. BPH Migas is, therefore, an outsider to this issue.
3.3.3. Road space limitation
In terms of the regulation of road specification, no ISO container will be allowed to
pass on the class III road because the width of any ISO container will not be
compatible with the width of Class III road.
Class III road is typical road in Indonesia, and it means that it is necessary to develop
dedicated container or lorry to transport LNG in local areas in Indoneisa. This is the
biggest challenge at this moment.

3.4. Role of each participant
In order to complete the entire value chain of mini-LNG transport, we need three kinds
of partners, namely, LNG provider for domestic market, distributors and end users. In
terms of LNG provider, Pertagas Niaga is only provider which can supply LNG for
domestic market in Indonesia. For transport, eight local distributors have been
appointed by Pertagas Niaga. Each local distributor has to find its own end users. PLN,
local governments and coal mining companies are also expected to become end users of
LNG. Through the trials by Pertagas Niaga and its distributors, some of partners of
trials are expected to be end users of LNG. Apart from these three stakeholders, the
equipments and facilities supplier could be considered as a local partner in Indonesia.
At this time, Japanese companies, consortium members, will establish a special
purpose company for this purpose.
The SPC is also expected to provide financial function by leasing/rental scheme and
maintenance and inspection service as well as consulting for users on how to use,
maintain and keep the safety.

3.5. Reference scenario setting
The methodology for GHG emission reduction estimation and monitoring would be
developed by following CDM methodologies as shown in Table 9. The project scope
includes three chains of transport, storage/vaporization and use. In each, several
methodologies can be applied. For example, AMS-III.AY and AMS-III.BC can be
applied for transport, AM0088 can be applied for storage and vaporization, and
AM0014, ACM0009 and ACM0011 can be applied for use of LNG. The symbol of circle
in the table shows that the CDM methodology can apply directly for this project, but
black triangle symbol suggests that we would have to modify CDM methodology to
some extent to apply it for this project.
We cannot, however, decide which methodology would apply to each process in the
beginning because it depends on the type of end user and we are still negotiating at
this point.

3.7. Promotion activities like seminars for Indonesian stakeholders
The first workshop on “promoting Japanese experience of mini LNG to Indonesia” was
held on 18th of February, 2015 at Intercontinental hotel Midplaza in Jakarta.
We had two sessions during the day. The morning session is for Pertamina and
Pertagas Niaga. Totally 11 officers including the director for Pertagas Niaga joined the
meeting. There were active discussions and Q&A on every page of the presentation.
The afternoon session gathered 13 officers from government bodies and distributors.
There were many questions and comments for the Japanese technologies and
distributors expressed actual needs in Indonesia and suggested to Air Water and
Kawasaki Heavy Industry officers to customize their products to suit Indonesian
situation.
In addition, the Bappenas officer suggested tendering opportunity to Toyota Tusho
officers for procuring satellite facilities along main roads in Indonesia.
The workshops were welcomed by Indonesian side and they strengthened their
understanding of mini-LNG facilities and equipments from technical and operational
perspective.

4. Analysis
4.1. Business plan
4.1.1. Project location
As of now, only one LNG loading facility is present in Bontang in the east Kalimantan
for domestic market. Bontang is the origin of mini-LNG transport. The potential end
users are located in Samarinda, Sangatta and Berau. Most of the potential users are
coal mining companies and their contractors, local governments, and power companies
like PLN. End user’ information is confidential from business perspective, so we cannot
disclose it.
In terms of the distance from Bontang, Samarinda and Sangatta are not so far, they
are less than or around 100km, but Berau is very far; it takes about 3 days by land
transport. In addition, road condition between Sangatta and Berau is not good because
the road goes over mountain area. The sea transport would therefore be examined in
the trial stage.
Japanese consortium discussed local distributors and some end users in these areas.
Finally, we focused on Kutai Timur government in Sangatta as the most promised end
user partner at this moment.

4.1.2.1. Current situation of power supply in Sangatta
Sangatta is 310km north from Balikpapan via Samarinda and Bondang. It is more
than a 9 hours drive from Balikpapan and almost 2 hours drive from Bontang. The
area belongs to Kutai Timur (East Kutai) provincial government. The government
office of Kutai Timur is located on the east end of Sangatta city area.
This area is very famous for coal mining. We can easily find open-cut coal mining in the
north direction from the hill top in the city area.

Recently, the electricity demand of households and business is growing. The only
demand which PLN knows excluding the demand of captive use in coal mining and
government sector is reaching a little lower than 16MW.
The peak demand of electricity has increased since 2009. In particular, we could find
sharp increase in demand between 2011 and 2012. The peak demand is still growing
every month. For such high peak demand growth, the power generators have been
added up to 15.8MW. In case the peak demand grows at the recent pace, the additional
capacity of power generation would have to be developed to cope with the demand
growth.

Now, the government and private companies have a total of 15.2 MVA power
generation plants near Sangatta with in 20 km from Sangatta city area. Apart from
Kutai Timur Government captive power plant and a total of 11 MVA privately owned
public use diesel generators, the rest of power generators have limited capacity of
power generation. They have a maximum of 250KVA capacity only. The reason for
such small capacity is the low demand. Besides, current high fuel cost doesn’t allow the
government to expand the capacity of power generators in remote areas in this region.
Hence, the local government of Kutai Timur looks for more economical and efficient
power generation system in this region.

In addition, the local government of Kutai Timur has 500 kVA generated by 7 units of’
captive power generators for their own use. The power is mainly used for lightening
building. The generators are developed two sets by two sets and the generators do not
always work at the same time. Depending on the demand of electricity by government
building, each power generator is switched on/off by the operators.
The fuel of these power generators is supplied from Samalinda. Storage capacity of
tanks is 20 kl by 2units. 50 to 60 tons of diesel fuel is consumed in a week. In total
3400 kl – 4000 kl diesel fuel was consumed per year. It is equal to 40 billion Rp. – 50
billion Rp. in 2014. The local government of Kutai Timul has a need to reduce this high
fuel cost and they can consider converting fuel from diesel to LNG if the economic
viability is confirmed.

4.1.2.2. Proposing plan of fuel conversion to LNG
We are proposing the following conditions as a first proposal to the local government.
Based on these conditions, we will negotiate and finalize the specification of converted
power generation sets.

4.1.2.3. Scale of investment & financial viability
Normally, one ISO container needs 30-40 million JPY, one satellite facility with 100 m3
storage needs 300-400 million JPY and one mini-LNG tanker with 1000m3 storage
tank needs 3-4 billion JPY. The total project costs would be estimated based on the
design of the project including how many containers are necessary, how many storage
facilities are necessary, and how many vessels are necessary. This time, we assume the
capex to be 5,960,168 USD in the first year. This is cost plus factor of fuel conversion.
The operation cost can be reduced by 1,225,216 USD. Therefore, the project owner can
pay back in almost 5 years without considering interest payment.
The point is that ISO containers and most of the equipments in satellite facility are
movable and we can use them even after some of clients stop using them. It means that
we propose leasing scheme with 20% interests per annum for 10 years. In this case, the
project owner can save 509,996 USD (60,689,498 JPY) annually.

4.1.2.4. Quantification of GHG emissions and their reductions
In Sangatta case, we assume two types of CO2 reduction opportunities.
The first opportunity is “use stage” and we introduce gas engine power generators
instead of diesel power generators. For this, ACM0011 of CDM methodology can be
applied for quantification of GHG emission reduction.
ACM0011 assumes fuel switching from coal and/or petroleum fuels to natural gas in
existing power plants for electricity generation and comparing between power
generations before fuel conversion and power generation after fuel conversion, namely
diesel generators and gas engine in this case.
As assumed in Table 12, we have calculated the amount of CO2 reduction following
ACM0011. The result is shown in Table 14. We have got 3,497 t-CO2/year from this
fuel switch and reduction rate reaches 36%.
Table 14 CO2 Reduction amount from fuel conversion
Items Unit Current After fuel conversion
CO2 emission amount t-CO2/yr 9,804 6,307
CO2 reduction amount t-CO2/yr 3,497
CO2 reduction rate % - 36%
The second opportunity is in “transport stage”. Given the situation of installing LNG
satellite system, we still need to transport fuel from Bontang. Of course we can shorten
the distance of fuel transport between Samalinda and Bontang, but shortening of
transport distance is not a substantial improvement to JCM scheme. It is because
conventional technology is still used for transport from Bontang. In this context,
conventional technology of transport is the technology which has already been
installed for the trail activities by Pertagas Niaga. The equipment is ISO container
manufactured by Chart, which is a famous company in the world in this field shown in
Figure 27.
The technology employed by Chart is “Super insulation” type and Air Water employs
“Composite” type (Figure 28). Composite type of ISO container has the best feature for
land transport from maintenance perspective (Figure 29). In addition, Air water
product is lighter than Chart products in per loading LNG amount. In case of 30ft
42
container, the Air Water product is lighter than the Chart product by 2.6 ton (Table 15).
Based on this weight gap, the following GHG reduction has been calculated.

As mentioned above, the key point of CO2 reduction is the weight gap from
conventional technology. This is a kind of “emission reductions” is through improved
efficiency of vehicle fleets (AMS-III.BC). The idea of calculation of CO2 emission is to
estimate the difference in fuel consumption from transport of LNG between
conventional container and the lightest container (Air Water product) between
Bontang and the destination.
44
According to the calculation, the transport using Japanese technology enables to
reduce CO2 emission by 7318.5 ton-CO2/year and totally reduces 10,815 ton-CO2/year
from both the stages (Figure 30). This reduction amount is almost equal to CO2
emission from 2000 households in a year in Japan. Accordingly, the CO2 reduction
amount from Sangatta case has a very significant contribution to the mitigation of
global warming.

4.1.2.5. MRV methods
In terms of the monitoring of CO2 emission, the following monitoring methods are
assumed. In terms of “use stage”, previous average diesel fuel consumption and
natural gas consumption should be compared. With regard to the “transport stage”, the
frequency should be monitored.

4.1.2.6. Service supply scheme
As mentioned before, the role of local partners is very clear (Table 8) and in the
Sangatta case, the roles are expected to be played. The detail service and financial
stream among stakeholders are shown in Figure 31.
According to the Indonesian regulation, logistics service should be provided by local
majority company. In this case, a distributor would be appointed, but we have not
decided which distributor would be appointed for this opportunity yet.

4.2. Proposed over all implementation schedule
We are assuming three steps for promoting implementation of mini-LNG transport
facilities and equipments. Pertagas Niaga has already conducted Ph1 trial, so we will
join them in Phase 2. Now, we assume to size up field test by land transport in Phase
2-1. In the Phase 2-2, we would like to check sea transport using barge system and ISO
container supported by top lifter. Then, finally, we would like to introduce mini-LNG
tanker for much larger scale transport of LNG. In parallel to the trial implementation,
the actual business implementation is also expected, but this is up to business
discussion with potential clients and local distributors.

In between January 2015 and January 2016, loading capacity is limited to 0.8-2
MMSCF/d, but in 2016, the loading capacity will increase to 30 MMSCF/d and in
January 2017, the capacity will reach to mini-LNG tanker size. By then, all
preparations are expected to be implemented.

4.3. Policy implication
4.3.1. Contribution to Indonesian Sustainable Development
The most important contribution of this project idea for sustainable development of
Indonesia is to not only introduce the mini-LNG transport facilities and equipments
and reduce GHG emission, but also enable developing huge opportunities in future to
convert primary energy source to natural gas and reduce GHG as well as other
pollutants. We cannot estimate positive impact from this idea precisely, but it is
believed that enormous positive outcomes can be achieved from this trial.
4.3.2. Capacity building to the host country
Capacity building on safety issues to handle LNG in Indonesia is also a very important
matter. According to Pertamina, it will control everything under its supervision during
the trial phase. So, no private entity is doing business in this field by itself.
Pertagas Niaga has already asked us to share our knowledge and experience in Japan,
and we held a workshop to transfer our knowledge on mini-LNG in Japan to
Indonesian stakeholders on 18th February, 2015.
During project implementation, the SPC will provide technical knowledge for
Indonesian stakeholders on how to handle the ISO containers and mini-LNG facilities.
Also, the SPC will provide the maintenance service of ISO containers because the
condition of vacuum of ISO containers is expected to be checked every ten years. This
technical service will be supported using Japanese technology. This maintenance work
would also prevent leakage of boiled gas from the container. Hence, this maintenance
will not increase GHG from the activity.

5. Conclusion and Next Steps
5.1. Conclusion
This study has reviewed the regulatory framework, development policy and progress of
technical feasibility study by Pertagas Niaga and its associated distributors. Also the
technical information of Japanese technology has been distributed to stakeholders in
the workshop.
During the study, we were able to identify the potential end users of LNG and conduct
rough economic feasibility study and roughly estimate CO2 reduction as the
environmental impact.
Finally, we could determine that the Sangatta case will enable significant amount of
CO2 reduction from LNG use as well as LNG transport. Therefore, it can be considered
that this case can be applied for JCM project scheme.
5.2. Next steps
Regarding Sangatta case, we are in the first proposal phase to the Kutai Timur
Government. We need a little time to involve the local government. Accordingly, the
next obvious necessary activity is to confirm the detail conditions with the local
government.
In addition, we are also approaching Pertagas Niaga and local distributors to conduct
the second step of technical feasibility study for large amount of transport from
Bontang to Sangatta by mini-LNG tanker or barge system with ISO containers. For
this trial, we also have to discuss detail design of feasibility study with Pertagas Niaga.
After finalizing all conditions for the next step, we would like to realize all
opportunities in Kalimantan Timur region. To promote this idea, we would like to
apply for the NEDO scheme. This is still under negotiation with NEDO.
As soon as we finalize all conditions, we would apply for NEDO.
