Clean Energy

Mining giant Rio Tinto has announced plans to install a pilot version of Heliogen's high-temperature "solar refinery" at a Californian boron mine, supplying clean energy as well as heat for industrial processes, with operations set to start in 2022.

Bill Gates's next-level nuclear power station is small, cheap, efficient and fast to build. It also has a built-in, on-demand energy storage system 10 times bigger than the biggest grid-scale batteries. Thanks to a DoE grant, it will open before 2030.

BP and Chevron have led a US$40 million investment round for a Canadian startup that claims to have developed a unique way to extract energy from geothermal heat on demand, using an unpowered looping fluid design that's already prototyped in Alberta.

Oil giant Shell is planning the biggest wind-to-hydrogen project in Europe, a colossal 10-gigawatt offshore wind farm in the North Sea feeding a massive electrolysis plant on dry land that'll pump out a million tonnes of clean H2 a year by 2040.

Spanish company Quaternium has destroyed its own record for gasoline-electric drone endurance with a 10-hour, 14-minute flight. But how does that stack up against hydrogen and batteries, and what are the implications for the emerging eVTOL market?

A Scottish company called Gravitricity has now broken ground on a demonstrator facility for a creative new system that stores energy in the form of “gravity” by lifting and dropping huge weights.

The structure that will house one of the largest and most ambitious energy experiments in history is now complete, with engineers working on the ITER Tokamak Building swinging their last pylon into place in readiness for the reactor's assembly stage.

A relatively new player on the nuclear fusion scene, a UK company called Tokamak Energy, is claiming a new milestone in the area after heating its ST40 device to 15 million degrees Celsius, similar to temperatures found at the center of the Sun.

​​Using the power of the sun to split water and produce hydrogen fuel is one of the most promising clean energy technologies being pursued. Now researchers at the University of Exeter have created a semiconductor material that should help make it viable.

​​​​Motorists traveling in electric vehicles along the coast in Australia's north will soon be able to keep their rides topped up for free, thanks to a new Electric Super Highway announced on Thursday.

​​Although only at the proof-of-concept stage right now, scientists in Belgium have come up with a way of capturing polluted air and converting it into power in the form of hydrogen gas, a technology that could prove a two-pronged environmental panacea.

Worldwide changes have prompted a big drop in the development of coal-fired power plants, a new study has found. Shifts in policy and economic conditions in China and India are central to the decline, says the report, which describes a 48 percent drop in overall pre-construction activity. ​
