Safety is one concern in 2020, a CO2 pipeline in Mississippi ruptured, releasing carbon dioxide that displaced breathable air near the ground and sent dozens of people to hospitals. In the United States, there’s opposition to CO2 pipelines that move carbon to storage sites. ![]() The pace of new projects is picking up, but they face significant obstacles. Carbon capture is just a sliver of the solution - less than 10% - but despite its comparatively small role, its expansion is still behind schedule. The IEA says the history of carbon capture “has largely been one of unmet expectations.” The group analyzed how the world can achieve net zero emissions and its guide path relies heavily on lowering emissions by slashing fossil fuel use. That’s a tiny amount - roughly 0.1% - of the 36.8 billion metric tons emitted globally as tallied by the Global Carbon Project. There are about 40 large-scale carbon capture projects in operation around the world capturing roughly 45 million metric tons of carbon dioxide each year, according to the International Energy Agency. Many experts say the technology to capture carbon and store it works, but it’s expensive, and it’s still in the early days of deployment. “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. “We call that a mitigation technology, a way to stop the increased concentrations of CO2 in the atmosphere,” said Karl Hausker, an expert on getting to net-zero emissions at World Resources Institute, a climate-focused nonprofit that supports sharp fossil fuel reductions along with a limited role for carbon capture. And even for industries trying to reduce emissions, some are likely to always produce some carbon, like cement manufacturers that use a chemical process that releases CO2. To stop those planet-warming emissions from reaching the atmosphere, businesses can install equipment to separate that gas from all the other gases coming out of the smokestack, and transport it to where it can be permanently stored underground. Lots of industrial facilities like coal-fired power plants and ethanol plants produce carbon dioxide.
