The state has managed to meet its demands using clean power, though it remains early daysCalifornia recently achieved an important renewable energy milestone, according to a report originally published by Electrik, in which it said that for 100 days, the state managed to meet 100 percent of its power grid demands for at least several minutes, using clean power.This doesn’t mean the state was powered in...

Chart: Almost all new US power plants are carbon-free

Wind projects made up 12 percent of new additions during the same period. Nuclear power contributed another 5 percent of the new capacity additions, thanks to the completion of the 1.1 GW Vogtle 4 reactor in April. Just 400 megawatts of new fossil gas went online in the first six months of 2024. If developers follow through with their construction plans for the second half of this year, the clean...

Fortera lands $85M to scale up low-carbon cement

Many of the world’s largest cement manufacturers, such as Cemex, Heidelberg Materials, and Holcim, are working on these options, in some cases with government support. But it’s far from clear whether carbon capture and storage is a technically and financially viable option for an industry that competes globally on very tight profit margins. Meanwhile, a variety of startups and government- and...

Hydrogen-Electric Air Taxi Prototype Successfully Completes Test Flight in California

Photo: Joby Aviation Joby Aviation has modified its pre-production S4 aircraft to develop a hydrogen-powered full-scale demonstrator. Supported by the U.S. Air Force’s Agility Prime program, this demonstrator completed a 523-mile (842-kilometer) test flight in California in 2024, significantly extending its range compared to the 155 miles (245 km) achieved by the battery-electric S4 in 2021. The...
