El MIT Tech Review nos cuenta cómo China ya está controlando las emisiones de contaminantes tradicionales, pero no el CO2. Y cómo para ello tendrá que gasificar el carbón, algo en lo que ya están invirtiendo.
Aunque claro, esta inversión todavía es cara, y la I+D no está dando el resultado previsto, tal y como nos cuenta Andrew Campbell. Si además el uso del carbón está disminuyendo:
Remarkably, thanks to a slowing economy, a shift toward lighter, less energy-intensive industries, and a crackdown on small, unlicensed coal burners, coal consumption in China fell nearly 2 percent in 2014, according the Institute for Energy Economics and Financial Analysis, even as the economy grew by 7.4 percent—the first such drop in decades. A Greenpeace report released in May found that coal consumption fell 8 percent in the first four months of 2015 compared with the same period a year before. If that trend continues for the full year, it would represent “the largest recorded year-on-year reduction in coal use and CO2 in any country.” As the U.S. shale gas revolution shows, dramatic swings in energy consumption can happen suddenly and unexpectedly. Pouring billions into expensive, futuristic clean coal plants may wind up looking, to future energy historians, like throwing good money after bad. “The argument that the coal industry always tries to make is to paint a picture where coal is critical for economic growth,” says Bruce Nilles, program director for the Sierra Club’s Beyond Coal campaign. “They used to say that about the United States, and now things are moving rapidly in the other direction. Now their last gasp is to try and create a sense of inevitability that coal is going to be burned for another 50 years in developing countries like China. But it’s based on false premises.”Quizá todas estas inversiones no tengan mucho sentido...Aunque nunca lo hubiera pensado, quizá estemos en un caso similar al de la nuclear, en la que también se invierten ingentes sumas de dinero, para poco resultado práctico.
