Cleaner, Cheaper Liquid Fuel from Coal - Technology Review
A new conversion process promises zero carbon emissions during production—but some question whether it will scale.
SRI International is developing a process that combines coal and natural gas to produce liquid transportation fuels that are substantially cleaner and cheaper to make than existing synthetic fuels.
SRI claims its process addresses three liabilities that have slowed the commercialization of the technology. By blending some natural gas into the conventional coal-to-liquids (CTL) process, the private research lab, based in Menlo Park, California, claims to have eliminated CTL’s carbon footprint, slashed water consumption by over 70 percent, and more than halved its capital cost.
