Assessment of Fuels for Power Generation by Electric Utility Fuel Cells.

摘要

The relative cost of fuel supply options for the production and distribution of fuels suitable for fuel cells was assessed,including the supply alternatives of hydrogen,synthesis gas (hydrogen/carbon monoxide),SNG,methanol,and naphtha,and raw energy sources for conversion to product fuels--petroleum,natural gas,coal and municipal solid waste. Comparative economics of fuel cell power systems from raw of primary fuel to electricity were developed based on forecasted energy prices for 1978-1990. Alternative systems costs were developed for both dispersed and base load fuel cell systems in Hartford,Dallas,Columbus,and Los Angeles. Where appropriate,integration of on-site fuel conversion with the fuel cell power section was considered to utilize waste heat and water from the stack. For base load concepts,integration of coal gasifiers with fuel cell plants was investigated. In most cases second generation fuel cell heat rates and capital costs were assumed. Capitol and operating costs for subsystems were prepared to establish module costs combined to obtain total system costs.
