That's not due to the oilfield service trucks rumbling in every direction servicing a boom in oil and gas production that has sent hotel rooms here north of $250 a night. It's certainly not the myriad of wells marked by flame-tipped flares with the rotten-egg odor of hydrogen sulfide wafting. What has George so excited is the $2.5 billion coal gasification plant that may well be the first of its kind when completed. The director of projects for Summit Energy Group's Texas Clean Energy Project, former Dallas Mayor Laura Miller, says the intention of the project is to "raise the bar forever so nobody can ever build a dirty coal plant again." This 400-megawatt project is an example of what the federal government or coal lobby would term a "clean" coal plant. It will collect a full 90 percent of its carbon dioxide gases — an expected 2.5 million tons per year — to sell into the oil patch for oil recovery. By separating hydrogen out from the CO2, TCEP will also be able to create a stream of urea to be sold as fertilizer to the tune of 700,000 tons a year. In fact, the fertilizer is the money maker here, according to Miller. After that in profitability terms comes electricity sales, followed by CO2 sales. Lastly, an estimated five percent of the company's revenue is expected to come from the sale of sulphuric acid, argon gas, and "inert non-leachable slag." Don't call TCEP a power plant, this is a "polygen" plant, producing a number of marketable streams that at day's end make the carbon capture process cost efficient. Meanwhile, the waste air emissions will add up to less than a typical gas-fired plant, and most of the heavy metals — including the neurotoxin mercury so typical of traditional coal plants — will be "vitrified," turned into glass beads that could then be potentially disposed of by mixing it into construction concrete. San Antonio's CPS Energy signed a 25-year Power Purchase Agreement for 195 megawatts from the plant as part of its ongoing attempt to replace dirtier sources of energy such as the 871-megawatt J.T.
