Giant 'Battery' Ensures Renewable Supply

Norwegian hydropower schemes linked to Europe’s large wind farm projects could successfully act as a backup when wind power fails to deliver enough energy, according to SINTEF, the largest independent Scandinavian research organization. With both on- and off-shore wind power being seen as key to reducing the EU’s carbon emissions by 80-95% by 2050, a big hurdle for the technology is solving the problem of intermittent power production. Sometimes there will be too much power on offer, and at others too little.
