Why Hydrogen From Coal? • U.S. reserves are huge • 250 year supply • H2 can be produced cleanly • H2 from coal is economical • Carbon capture and storage addresses climate change • Diversifies the source of H2 • Provides the bridge to production of H2 from renewable sources and nuclear Fossil Energy Reserves1 Quads 1 -- Proved oil and gas reserves, and recoverable coal reserves WRIGHT / Zero-Emission Energy Plants / The Energy Advancement Leadership Conference / Houston, Texas / 18 November 2004
FutureGen • Nearly $1 billion (U.S.) , 10-year demonstration project to create the world’s first coal-based, zero-emission electricity and hydrogen plant • Test new technologies • Nominal 275-MWe • 1 million tonnes CO2 per year • Sequester the CO2 • Produce H2 WRIGHT / Zero-Emission Energy Plants / The Energy Advancement Leadership Conference / Houston, Texas / 18 November 2004
