Domestic Measures on Global Warming after COP21

Based on The Paris Agreement, Japanese government compiled “The Global

Warming Prevention Measures Plan” by Global Warming Prevention

Headquarters.

Simultaneously, the government compiled “Energy & Environment Strategy

for Technological Innovation” and “Innovative Energy Strategy” specifying the

hopeful innovative technologies .

“Based on the Paris Agreement, we have formulated a

global warming prevention measures plan, paving the way

to achieve our goal to reduce global greenhouse gas

emissions 26% by 2030.

Within a fair and effective international framework, in which

all major countries participate, we will lead international

society so that each major country reduces its emissions in

accordance with its ability, and we have indicated our

direction of aiming to achieve the long-term goal of

reducing global greenhouse gas emissions 80% by 2050,

while both implementing global warming prevention

measures and sustaining economic growth.http://japan.kantei.go.jp/97_abe/actions/201603/15article1.html

Key points of the strategy1.Thorough energy efficiency and conservation

• Expanding the scope of targets of the Energy Efficiency Benchmark Program to all industries

• Enhancing the introduction of energy efficiency and conservation efforts into the fields of SMEs

（Small and Medium-sized Enterprises）, house and transportation

2.Expanding the introduction of renewable energy-Ensuring compatibility between maximum

introduction and expansion, and inhabitation of public burden

3.Establishing new energy systems• Simultaneously encouraging new entrants to the field of electricity and reducing carbon dioxide

emissions

• Starting up an integrated energy system of renewable energy and energy efficiency and

conservation are integrated

• Establishing an energy system of local production for local consumption

New development of the energy efforts through Innovative Energy

Strategy1.Paradigm shift of the energy efficiency and conservation policies

2.Creating low-carbon power-source market and reestablishing renewable energy industries

3.Innovation of energy industries utilizing IoT

4.Establishing a strategy for creating hydrogen society

toward the post-2030 era5.Realization of the Fukushima plan for a new energy society

Hydrogen energy system has drawn the

attention as one of the technologies for

mitigation of Global Warming.

1. Plural booms of H2 Energy Research in the past resulted in calming-down

⇒ current H2 upsurge : global warming, technological progress in FC and H2,

participation of major corporates aiming at commercialization

2. Dissemination of an energy systems is strongly dependent on external factors

eg. Global Warming, Resource of Fossil Fuel, Geopolitics, Competing Energy Systems

⇒Hypothesis: energy systems, that give solution to current important issues,

become dominant

Examples important issue:1. Global level : Sustainability2. National level : Energy security

3. Note that various energy systems

have potential to solve the important issues

Studies cited above shows:

1. technological and economical feasibility of transportation of CO2-free H2

produced overseas to Japan

2. it does not necessarily imply that CO2-free H2 will be utilized in large-scale

as the major energy in Japan

In this connection, the expected market size of CO2-free H2 is estimated.

Hydrogen has the potential for a major energy resource under severe CO2 constraints.

Note that the total primary energy supply decreases with population and improvement of

energy efficiency.

IEA shows scenarios of introduction of electricity from renewable energy as

the measure against the global warming and energy security issues.

Introduction of large quantity of electricity from renewable energy is

considered to make issues caused by surplus electricity and abrupt variation

of power.

Research and demonstration on utilization of H2 as the buffer for the

variation is actively conducted overseas as well as in Japan.
