Main political drivers towards H2 economy

• Improved security of supply

• Reduced CO2-emission (Kyoto, >8% reduction by 2010)

• Improved air quality




The transition to the hydrogen economy will be lengthy, costly and will require significant R&D

PRACTICAL STRATEGY

TRANSITION TO H2 ECONOMY




Offering smooth transition by initially conveying a hydrogen/natural gas mixture

Advancing use of H2 in shorter time-frame by extracting hydrogen from the mixture

Lowering costs by using the existing system

Providing opportunity to carry H2 to dispersed users through widespread natural gas system

Natural gas system could promote transition by:

•Presence of hydrogen may affect:–Safety of transmission, distribution, and end-use–Pipeline durability and integrity–Gas appliance performance

•Hence….The NaturalHy Project

Impact of adding H2 to Natural Gas System




NATURALHY Project Objective

Preparing for the hydrogen economy by defining the conditions under which the

existing natural gas system can be used for mixtures of hydrogen and natural gas, and where hydrogen can be separated from the

mixture downstream by membranes.




• 39 European partners, including 15 from the gas-business

• Integrated Project within FP6

• Project budget: 17.3 M€; EC grant: 11 M€

• Start 1 May 2004 for 5 years

The involvement of a broad assembly from the European gas industry is important because:

• Differences in the pipeline systems;

• Differences in the composition of the gases;

• Gas companies are very careful with changes (some call it “conservative”);

• To obtain the support of all stakeholders.

Project Structure

Divided into six technical work packages Excluding:

Hydrogen production Hydrogen utilisation

Key focus on: Socio-economic and life cycle analysis Durability and Integrity of pipelines Impact on overall safety Effect on existing gas appliances Membranes for selective withdrawal of hydrogen Decision tool to aid assessment of system suitability

Dissemination of results Strategic Advisory Committee





Safety Performance

Integrity Standards and norms

Full H2-area

H2-production

Natural gas production

Socio-economic & LCA

Dissemination (in cooperation with HYSAFE)

H2-MembranesDurability

Collaboration with HYWAYS (roadmap development)



Focus on Safety

Safety of Appliances Flame instability?

Pipeline System Durability Hydrogen induced cracks? Will smaller defects lead to failure? Are plastic pipes permeable for hydrogen? Are meter seals permeable?

Pipeline Integrity Will smaller defects be significant? Can defects be detected and repaired?



Focus on Safety

Safety of the Public Increase in leakage due to hydrogen? Increased likelihood of accidental

release due to detrimental effect of hydrogen on materials?

Increased likelihood of ignition? Increased severity of consequences (eg

explosions) due to reactivity of hydrogen?




Durability of Pipelines

Laboratory tests to assess effect of H2 on fracture toughness and fatigue crack growth

Investigation of the effect of H2 on the evolution of defects

Full scale fatigue and burst tests with defined defects

Numerical modelling of rapid crack propagation Laboratory tests on polymer permeability and

ageing Tests to assess effect of hydrogen on meter

components



Integrity of Pipelines

Assess minimum critical defect size by predicting the crack growth behaviour in presence of hydrogen

Assess current inspection techniques for detecting minimum defect size and improve the techniques

Assess current repair techniques for use in presence of hydrogen and improve as required

Develop integrity management tool for specifying pipeline inspection and maintenance plans




Burner, max 12% H2

Pipeline (safety zone), max 10% H2

Piece of pipe (durability), max 6%

Considered H2

40 bar

8 bar

8 bar

CPH-turbine, max 15% H2

Summary

The NaturalHy Project aims to encourage and facilitate a transition

to the hydrogen economy on a shorter timeframe by providing a transitional period based on using the existing gas infra-structure to convey a natural gas/hydrogen

mixture




Summary

The project will assess the feasibility of using the system for NG/H2 mixtures, establish the limits of operation and methods for extracting hydrogen

A strong emphasis is placed on the continued integrity of the pipeline system and the safety of the public
