Researchers from SRI International (SRI) are developing a methane-and-coal-to-liquids process that consumes negligible amounts of water and does not generate carbon dioxide. In conventional CTL approaches, energy is supplied by burning a portion of the coal feed, which then produces carbon dioxide.

Ceres recently released a new report concluding that coal-to-liquid (CTL) and oil shale technologies face significant environmental and financial obstacles—from water constraints, to technological uncertainties to regulatory and market risks—that pose substantial financial risks for investors involved in such projects.

Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT. The first two reports dealt with nuclear power (2003) and coal (2007).

The projects—led by FuelCell Energy, in partnership with VersaPower Systems, and Siemens Energy—have successfully demonstrated solid oxide fuel cells (SOFCs) designed for aggregation and use in coal-fueled central power generation. Cost of $700 per kilowatt (2007 dollars) for an integrated fuel cell power block.

PERC identifies more than 13 million vehicles worldwide in 2007 as propane-fueled.) PERC estimates that operating costs of a propane fleet typically range from 5 to 30% less than a gasoline-powered fleet, when capital costs (vehicle and infrastructure) and operation and maintenance costs are all taken into consideration.

Adding biomass to the coal in the CTL process (Coal and Biomass to Liquids, CBTL) can reduce the GHG emissions further, according to the study. The study evaluated the performance and cost of three types of plants (CTL, CBTL and BTL) in 11 different configurations at capacities up to 50,000 bpd. EPA and EISA 2007.

Algae could well play a valuable subsidiary role, especially if its use as a biofuel feedstock can provide the added benefit of improving water quality. The decrease in congestion on Auckland’s motorways when the price of a liter of petrol rose above two dollars in 2007 is testament to this flexibility, he said. per liter (US$5.12/gallon
