At this point, Brown and Palmer were still planning to use coal as their fuel. But when they sent Allam's handiwork to the engineering firm Babcock & Wilcox, to see whether the system would work on an industrial scale, "they had good news and bad news," Brown says. On the downside, the Allam cycle would be tough to pull off with coal, at least initially, because the coal would first have to be converted to a synthetic gas, which adds cost. Also, sulfur and mercury in that syngas would have to be filtered out of the exhaust. But on the upside, the engineers saw no reason why the technique wouldn't work with natural gas, which is ready to burn and doesn't have the extra contaminants.
Brown and Palmer gave up on winning a clean coal grant from the government. Instead, they sought private investment for a far bigger prize:
