Ecojet airline aims to fly hydrogen-electric aircraft from 2025

Ecojet intends to refit conventional kerosene-fueled aircraft with hydrogen-electric powertrains, and operate as the

Green-energy businessman Dale Vince has revealed plans to set up the UK’s first electric aviation company. Ecojet will repurpose conventional aircraft to fly on hydrogen-electric power, with domestic flights planned to start as early as 2025.

Super-cheap gigawatt-scale rust battery greenlit for Minnesota

Gates- and Bezos-backed startup Form Energy is one of the most exciting companies in the grid-level renewable energy storage space, with a multi-day iron-air battery system just 10% the cost of lithium. A 10-MW/1-GWh demo system has now been approved.C… Continue reading Super-cheap gigawatt-scale rust battery greenlit for Minnesota→

“Walking” anchor and plasma drill promise cheap, deep geothermal power

The intense heat under the Earth’s surface represents a virtually inexhaustible source of reliable clean energy that would be available 24/7 from anywhere on Earth – you could pull it up as steam to run generator turbines, or pipe it directly into dist… Continue reading “Walking” anchor and plasma drill promise cheap, deep geothermal power→

Tiny holes key to making lightning-like energy from air, says study

As anyone who’s ever witnessed a bolt of lightning streaking through the sky knows, the air around us can be filled with an astonishing amount of energy. A new study shows that some of this energy can be harvested using a simple perforated nanofilm tha… Continue reading Tiny holes key to making lightning-like energy from air, says study→

Pivoting arms could stabilize massive floating offshore wind turbines

As we’ve discussed many times before, offshore wind represents an enormous opportunity for clean energy, but some of the best resources are out in deep water, where sinking a shaft straight into the sea bed becomes prohibitively expensive and difficult… Continue reading Pivoting arms could stabilize massive floating offshore wind turbines→

New Renewable Energy Projects Are Overwhelming US Grids

It’s been clear for a long time that the world has to move away from fossil energy sources. Decades ago, this seemed impractical, when renewable energy was hugely expensive, and …read more Continue reading New Renewable Energy Projects Are Overwhelming US Grids→

GE installs world’s first spiral-welded wind turbine tower

The strongest winds tend to be higher up, but as this 2022 study shows, higher-mounted turbines catching stronger wind doesn’t necessarily equate to the lowest cost of energy. Indeed, once you factor in the costs of stronger foundations and taller, stu… Continue reading GE installs world’s first spiral-welded wind turbine tower→

Silver mirror triples efficiency of perovskite solar cells

Perovskites are one of the most promising new materials for solar cell technology. Now engineers at the University of Rochester have developed a new way to more than triple the material’s efficiency by adding a layer of reflective silver underneath it….
