Why carbon capture hasn’t saved us from climate change yet.
. All of them are pulling carbon dioxide out of the emissions from an associated factory or power plant. Systems that pull CO2 out of the ambient air, like the ones Andrew referenced in his question, do exist. They’re just harder and more expensive to operate because the concentration of CO2 in the air is so much lower, Nemet said. “At a power plant, 10 to 20 percent of what goes up the smokestack is CO2, compared toSo generally speaking, the technology of carbon capture is ready to go.
Other climate-adjacent industries, such as electric vehicles and solar photovoltaics, have grown rapidly in the past decade. But Lashof pointed out the other industries offer benefits outside of their climate impact. “Solar is generating electricity you can sell. Electric cars are really fun and fast and you don’t have to go to the gas station. There’s a market for that independent of climate benefits,” he said.
In a world where trapped carbon emissions are essentially worthless, there’s not much reason for companies to invest in a technology that does nothing but reduce carbon emissions, experts told me. Wind, solar and electric cars were all able to start small and build on niche demand. But CCS hasn’t really been able to do either of those things, said Howard Herzog, senior research engineer at the MIT Energy Initiative.
This in part explains why CCS boosters have so much enthusiasm for the idea of finding ways to monetize captured CO2. It’s not just about winning at business. Barring the miraculous passage of a carbon tax, it might also be about the only way to get crucial climate tech off the ground.is sucking CO2 directly out of the air and selling it to soda companies and agricultural interests. “They pump it into greenhouses to increase the yield on tomatoes,” Nemet said.
There are some policies that will likely help CCS solve its market problems. In 2018, Congress passed
