The Biden administration wants more investment in carbon capture and removal, too, building off America’s comparatively large spending compared with the rest of the world. The American Petroleum Institute says oil and gas will remain a critical energy source for decades, meaning that in order for the world to reduce its carbon emissions, rapidly expanding carbon capture technology is “key to cleaner energy use across the economy.” A check of most oil companies’ plans to get to net-zero emissions also finds most of them relying on carbon capture in some way. “We have to remove some of what’s in the atmosphere in addition to stopping the emissions,” said Jennifer Pett-Ridge, who leads the federally supported Lawrence Livermore National Laboratory’s carbon initiative in the U.S., the world’s second-leading emitter of greenhouse gases. And some industries, like shipping and aviation, are challenging to fully decarbonize. For example, despite notable gains for electric vehicles in some countries, gas-fired cars will be operating well into the future. One type directly captures it from the air, using chemicals to pull out carbon dioxide as air passes through.įor some, carbon removal is essential during a global transition to clean energy that will take years. This already happens when forests are restored, for example, but there’s a push to deploy technology, too. Instead of capturing carbon from a single, concentrated source, the objective is to remove carbon that’s already in the atmosphere. The captured carbon is concentrated into a form that can be transported in a vehicle or through a pipeline to a place where it can be injected underground for long-term storage.
