Pumped up potential
18 January, 2013
Currently the only technology available to provide the large electricity storage required to meet 2020 EU renewable energy targets, pumped storage can have fewer environmental and social impacts if existing dams and reservoirs are converted to this mode of hydropower. However the technology’s potential on a Europe-wide scale has never been thoroughly explored. This has prompted a joint research collaboration to develop a new methodology to assess the situation.

The tail end of a story
