Sea-bed ‘air batteries’ offer cheaper long-term energy storage

Israeli company BaroMar is preparing to test a clever new angle on grid-level energy storage, which it says will be the cheapest way to stabilize renewable grids over longer time scales. This innovative system lets water do the work.Continue ReadingCat… Continue reading Sea-bed ‘air batteries’ offer cheaper long-term energy storage→

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→
