MIT researchers propose subsea version of pumped hydro for renewable energy storage

Green Car Congress

Researchers at MIT are proposing using a variation on pumped hydroelectric systems for storage of electricity produced by offshore wind farms. The 1,000 wind turbines that the spheres could anchor could, on average, replace a conventional on-shore coal or nuclear plant. MIT has filed for a patent on the system. Earlier post.).

One wonders if the recent headway at MIT in building lithium ion cells using ?virus? Denmark did that with Wind Power and now most of their energy comes from wind rather than oil, natural gas, or coal. We should have built more Nuclear power plants and created a nuclear waste recycling program. Interesting in any case.
