"This latest announcement is illustrative of the types of technological innovations that will be needed for the U.S. and the world to effectively decarbonize the economy in the future. Addressing climate change will necessitate an ‘all of the above’ approach to not only limit future emissions from reaching the atmosphere by expanding the use of technologies like hydropower, nuclear, geothermal, and renewables, but will also require cleaning up the current atmosphere."

"Carbon-capture technology can gather carbon dioxide from smokestacks or other industrial equipment, compress and liquefy it, and then pipe it to underground storage locations. This project, expected to start in 2026, would capture about 800,000 metric tons of carbon a year from producing iron used in steel, and bring Exxon’s (XOM) total project pipeline to more than 5 million tons a year."

"Vidyut explained that his drive for launching Takachar and advancing clean tech started early, sharing, 'I grew up in New Delhi, and the city is known to have one of the worst air qualities in the world. You can see it around here right now, right? This is due to the open burning of agricultural waste here. So every winter, we would have very bad air quality and part of it would be contributed by the open burning of agricultural waste in farms surrounding the city.'"

"Similar to drilling for oil and natural gas, companies pursuing underground hydrogen would have to lease drilling sites from landowners and obtain mineral rights, which vary by state. Unlike oil or natural gas, hydrogen doesn’t pollute waterways or the environment with toxic chemicals. However it can be dangerous and is flammable."

"The Chevelon Butte Ranch, which has been owned and operated by members of the O’Haco family for more than a century, is famous for its history of raising livestock, which over the years has included sheep and horses. The ranch today is known for its herd of Black Angus cattle. Parts of the ranch are used by hikers and rock climbers, as well as by fishermen and hunters."

"In December 2020, Kairos received a Department of Energy Advanced Reactor Demonstration Program award for risk-reduction funding to support the development, construction, and commissioning of Hermes in collaboration with Oak Ridge National Laboratory, Idaho National Laboratory, Materion Corporation, and the Electric Power Research Institute. The total award value is $629 million over seven years, with the DOE contributing $303 million."

"Last year Zap raised $160 million in a round led by Chris Sacca’s Lowercarbon Capital. Its additional investors are Breakthrough Energy Ventures, Shell Ventures, DCVC, Valor Equity Partners, Addition, Energy Impact Partners, and Chevron Technology Ventures."

"Another advantage of relying on electricity is that the world already produces and distributes plenty of it, whereas almost no infrastructure yet exists for making and supplying hydrogen. To top things off, Boston Metal’s approach is based on cells that are much smaller than furnaces. That makes electrolytic production modular and easy to scale up."
