Giant, megawatt-scale wave energy generator to be tested in Scotland

Irish company OceanEnergy has already tested its oscillating water column generators at significant scale in Hawaii, and it’s just signed on to a four-year project to test, validate and commercialize its biggest unit yet off Orkney, in Scotland. The OE… Continue reading Giant, megawatt-scale wave energy generator to be tested in Scotland

Rooftop wind system delivers 150% the energy of solar per dollar

Aeromine says its unique “motionless” rooftop wind generators deliver up to 50% more energy than a solar array of the same price, while taking up just 10% of the roof space and operating more or less silently. In independent tests, they seem legit.Cont… Continue reading Rooftop wind system delivers 150% the energy of solar per dollar

Blowhole wave energy could soon be world’s cheapest clean power

The UniWave sea platform is an artificial blowhole that harvests energy from ocean waves. Independent analysts now predict it’ll create some of the cheapest renewable energy on the market – and some of the most reliable and predictable, as well.Continu… Continue reading Blowhole wave energy could soon be world’s cheapest clean power

Satellite power grid would beam energy around the globe just like data

Emrod has just demonstrated its wireless power beaming technology to Airbus and the European Space Agency (ESA) as part of the ESA’s new push toward 24-hours-a-day space-based solar power. The idea of space-based solar is not new. The problem has alway… Continue reading Satellite power grid would beam energy around the globe just like data

Thyssenkrupp may have just cleared the path to bulk green steelmaking

German steel giant Thyssenkrupp is investing US$1.9 billion in a hydrogen-powered direct-reduction system that can create high-quality steel without needing the rare, high-grade iron ore required by most green steel processes. This could open the flood… Continue reading Thyssenkrupp may have just cleared the path to bulk green steelmaking

Five solar farms, each as big as Tasmania: Australia’s path to net zero

Australia has a lot of sun and desert space, positioning the country well to continue being an energy exporter in the net zero era. But the renewable assets it’ll need to build to get there are absolutely epic in scale, according to a new report.Contin… Continue reading Five solar farms, each as big as Tasmania: Australia’s path to net zero

World’s first direct air electrolyzer makes hydrogen from humidity

Australian researchers have developed and tested a way to electrolyze hydrogen straight out of the air, anywhere on Earth, without requiring any other fresh water source. The Direct Air Electrolyzer (DAE) absorbs and converts atmospheric moisture – eve… Continue reading World’s first direct air electrolyzer makes hydrogen from humidity

1-MW floating vertical axis wind turbine to be deployed off Norway

We’ve been banging on a bit about floating offshore wind turbines lately, but with good reason. Take a look at the US Energy Information Administration’s projected Levelized Cost of Energy (LCoE) figures for 2027, on page 9 of this report. Deep offshor… Continue reading 1-MW floating vertical axis wind turbine to be deployed off Norway

China discovers new mineral – and a fusion energy source – on the Moon

It seems China’s Chang’E-5 robotic Moon mission has discovered more than water on the lunar surface. Scientists have confirmed the discovery of a new mineral, a transparent crystal named Changesite-(Y), as well as a promising potential fusion fuel.Cont… Continue reading China discovers new mineral – and a fusion energy source – on the Moon
