Clean Energy

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. ​

​​Back in 2015, Google launched a clever venture called Project Sunroof that used Google Maps data to assess the solar potential of individual roofs. It has now expanded to cover every US State and the data makes a compelling case for solar power indeed. ​

Climate change has made the search for efficient sources of renewable energy more urgent than ever before. But how does one store and deliver energy sources like solar and wind power? The answer might lie in a fluorescent dye known as BODIPY.

​When Solar Impulse completed its solar-powered flight around the world, it was more than just a stunt … it was a way of showing how clean tech can be put to practical use. Now, Solar Impulse has taken another step in that direction, by announcing its World Alliance for Clean Technologies.

An Asia-based group of entrepreneurs has put forth a vision for a global, interconnected energy grid that connects energy users with renewable generation sources half a world away. Starting with an Asia wide super grid, GEIDCO is aiming for a connected world by 2050.

Renewables have now overtaken coal as the world's largest source of installed power capacity, and the agency's projections over the next five or so years paint a pretty promising picture for the industry indeed. ​
