90-GWh thermal energy storage facility could heat a city for a year

An energy supplier in Finland has announced the upcoming construction of an underground seasonal thermal energy storage facility about the size of two Madison Square Gardens that could meet the heating demands of a medium-sized city for up to a year.Co… Continue reading 90-GWh thermal energy storage facility could heat a city for a year

Self-assembling crane promises to halve cost of offshore wind setup

Part of the exorbitant cost of offshore wind energy is the massive crane ships required to install the damn things – but Norwegian company Windspider has come up with a brilliantly lightweight crane system that promises to slash costs in half.Continue … Continue reading Self-assembling crane promises to halve cost of offshore wind setup

Video: Wave-amplifying generator bounces twice as high as the swells

Sweden’s CorPower has announced “breakthrough” results from Atlantic ocean testing of its full-scale floating generators, which cleverly time their motions to amplify smaller waves while protecting themselves against dangerous storm conditions.Continue… Continue reading Video: Wave-amplifying generator bounces twice as high as the swells

Massive geothermal potential found offshore, where the Earth splits

A potentially game-changing and largely unexplored energy jackpot lies beneath the ocean floor, according to a whitepaper from geoscience tech consultancy CGG. Unique conditions under the sea bed promise cheaper and more accessible geothermal power.Con… Continue reading Massive geothermal potential found offshore, where the Earth splits

28-ton, 1.2-megawatt tidal kite is now exporting power to the grid

Minesto’s fully operational Dragon 12 looks like some sort of futuristic military drone – but it behaves remarkably like a kite underwater. It uses lift generated by tidal flows to fly patterns faster than the currents, harvesting renewable energy.Cont… Continue reading 28-ton, 1.2-megawatt tidal kite is now exporting power to the grid

WaveRoller sea-floor generator approaches commercial deployment

Wave energy remains one of the least-exploited clean energy options, with huge potential as part of a green energy grid. Finland’s AW Energy is preparing to field a contender at scale – the Waveroller – which sits on the sea bed generating up to 1 MW.C… Continue reading WaveRoller sea-floor generator approaches commercial deployment

Orbital reflectors could boost solar energy around dusk and dawn

Power demand spikes in the early morning and later evening, when solar arrays can’t help. But researchers in Scotland say orbital launch costs are getting so cheap that giant space-based reflectors could soon be a viable way to power these timeslots.Co… Continue reading Orbital reflectors could boost solar energy around dusk and dawn
