Last month, a government watchdog report found that more than $1 billion in public funds for carbon capture projects resulted in few working projects, and no power plants with carbon capture currently in operation. WA Parish generating station in Thompsons, Texas, in 2017. A pipe installed as part of the Petra Nova Carbon Capture Project carries carbon dioxide captured from the emissions of the NRG Energy Inc. But its operator shut it down in 2020 for economic reasons when the price of oil plummeted and the plant could no longer sell its captured CO2 profitably. Cost overruns and scheduling issues also plagued Hydrogen Energy California, a proposed coal-powered plant in Kern County, California.Ī coal-powered plant in Thompsons, Texas, dubbed Petra Nova, opened in 2017, becoming the only U.S. The many efforts to capture carbon from coal plants have ended with failure.Ī Kemper, Mississippi, power plant was years behind schedule and billions over budget on its carbon-capture plans before shutting down. all in industrial facilities, including fertilizer plants and gas plants. There are a handful of carbon capture facilities currently operating in the U.S. However, the technology so far hasn't lived up to its promise. Once captured, the CO2 can be transported and injected underground forever - if it works as intended. Several methods can be used to capture carbon, including chemical solvents, membranes or even bacteria. Cement trucks at the Iskitim Cement Plant in Russia's Novosibirsk region on January 23, 2019. Carbon pollution, he added, "s inherent in the chemistry of fertilizers, in glassmaking, in hydrogen production that comes from natural gas." Globally, industrial processes make up nearly one-third of carbon emissions. "Sixty percent of the carbon emissions from a cement plant have nothing to do with how the plant is heated up - it's entirely the chemistry that converts raw materials into cement," said Friedmann. It's an essential substance - and the third-largest source of carbon pollution in the world, ranking behind China and the U.S. Carbon capture is touted as a possible solution for heavily polluting sites like oil and gas fields, cement factories, steel mills or power plants run on fossil fuels. While "carbon removal" refers to pulling out emissions humans have already put in the atmosphere, "carbon capture" refers to containing that pollution at the point it's being created - like putting a scrubber on a smokestack. The International Energy Agency last year projected that carbon capture would account for nearly 15% of all the ways that we remove carbon, and the International Panel on Climate Change endorsed it as part of a suite of net-zero CO2 emissions scenarios.Ĭarbon capture is distinct from carbon removal. And lawmakers are debating dramatically increasing funding for carbon capture in the stalled Build Back Better Act.Ĭarbon capture, which removes CO2 emissions from high-polluting sources like industrial facilities or power plants, could play an increasingly important role in global efforts to stave off the worst effects of climate change, according to international regulatory bodies. Last year's infrastructure legislation gave the largest amount of funding ever to carbon capture projects, at $12 billion. While much of President Joe Biden's climate change agenda has stalled in Congress, there is one nascent - and controversial - technology for reducing carbon emissions that has received billions in public funds in 20: Carbon capture.
