NATURALHY: Assessing the potential of the existing natural gas network for hydrogen delivery Onno Florisson – KEMA (representing N.V.Nederlandse Gasunie) GERG Academic Network Event Brussels, 4th June 2010 Experience you can trust. This Presentation • Introduction • NATURALHY approach & focus • Work performed and conclusions: – WP Safety – WP Pipeline material durability – WP End Use • Summary Hydrogen as an Energy Carrier • Many ways of sustainable production • Low pollutant emissions when combusted • Can be transferred to electricity with high efficiency and v.v. • A by-product in chemical processes • Produced from coal gasification (with CCS) • Hydrogen offers an opportunity for the greening or de- carbonising of natural gas EC Directive 2003/55/EC “… taking into account the necessary quality requirements, biogas and gas from biomass or other types of gas are granted non-discriminatory access to the gas-system, provided such access is permanently compatible with the relevant technical rules and safety standards…. ” NATURALHY focus • The conditions under which hydrogen can be added to natural gas in the existing natural gas system with acceptable consequences • Technologies for the selective withdrawal of hydrogen from hydrogen/natural gas mixtures • Socio-economic and environmental consequences of the NATURALHY-approach Natural gas delivery chain High pressure grid, 64-40 bar Medium Distribution End user End user pressure grid, grid, <8 bar infrastructure appliance 40-8 bar Industrial Industrial end user end user Industrial Pressure reduction end user facility H2-addition scenario Hydrogen addition to the medium pressure grid High pressure grid, 64-40 bar Medium Distribution End user End user pressure grid, grid, <8 bar infrastructure appliance 40-8 bar Membrane Industrial Industrial H2 end user end user FuelCell Industrial end user Pressure reduction facility Adding H2 to Natural Gas Change of the chemical and physical properties of the gas in the network and the gas delivered: • Combustion properties • Diffusion in materials • Dispersion in air • …….. Impact of Adding H2 to Natural Gas • Risk (probability of failure x effect) • Pipeline material properties • Integrity management for pipelines • Gas quality management • The required regulations, codes & standards NATURALHY Organisation Diagram WP Durability WP LCA & Socio- WP Integrity Econ.
