Swords to ploughshares: Hyme re-jigs old power plants for clean energy

Denmark’s Hyme Energy wants to save decommissioned fossil-fuel heat and power plants by repurposing them as super-cheap renewable energy storage and release facilities, using cutting-edge molten salt technology borrowed from the advanced nuclear sector… Continue reading Swords to ploughshares: Hyme re-jigs old power plants for clean energy

“Telescoping can” wave energy device beats test predictions by 20%

Scotland’s AWS Energy has reported results some 20% better than predicted for its Archimedes Waveswing, a prototype wave energy generator that’s been undergoing ocean-based testing at the European Marine Energy Centre (EMEC) in Orkney for the last six … Continue reading “Telescoping can” wave energy device beats test predictions by 20%

Caltech’s space solar project prepares for its first orbital prototype

Caltech’s wildly ambitious space solar project, buoyed by a massive hundred-million-dollar donation, is preparing to launch its first prototypes into orbit. These cutting-edge ultralight structures will collect, convert and wirelessly send energy.Conti… Continue reading Caltech’s space solar project prepares for its first orbital prototype

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

Record energy haul: Offshore prototype operates over capacity for 24 hrs

A prototype wind turbine has recorded an extraordinary single-day renewable energy production total, bringing in a massive 359 megawatt-hours in a 24-hour time period. To get there, it had to operate over its rated capacity, essentially all day long.Co… Continue reading Record energy haul: Offshore prototype operates over capacity for 24 hrs

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

World’s largest flow battery connected to the grid in China

The Chinese city of Dalian has just switched on a world-leading new energy storage system, expected to supply enough power for up to 200,000 residents each day. With an initial capacity of 400 MWh and output of 100 MW, the Dalian Flow Battery Energy St… Continue reading World’s largest flow battery connected to the grid in China
