Yes, Elon Musk is working on carbon capture technology. He has been focusing on developing ways to capture carbon dioxide (CO2) emissions from factories, power plants and other industrial sources, and store, or sequester the gas, either in the soil or underground.
In June 2019, Musk announced the formation of The Boring Company, which is focused on finding ways to capture and sequester CO2. He stated that “such a breakthrough would be a game-changer for the fight against global warming” and that the company would be “actively working on technologies that can capture carbon at a large scale”.
In November 2019, The Boring Company was awarded a contract to develop carbon capture technology for a large industrial-scale facility in the United States. The company is working to develop a way to capture emissions from a variety of sources, including cement plants, oil refineries and other manufacturing processes.
Musk has stated that carbon capture technology could help drastically reduce emissions and has the potential to slash the global emissions of CO2. He believes that the technology is an essential piece of the global efforts to reduce climate change and accelerate the transition to renewable energy sources.
