Creative ways to store electrical power using alternative energy such as wind and solar. The argument about continuing with non renewable resources is getting thinner and thinner. Yes, facilities like these will be expensive, just as the systems we currently have were in the beginning.
From Daryan Energy Blog: Proposals for mega sized pumped storage facilities in Scotland to back up intermittent renewables, such as wind. Certainly these proposals do get around one of the major myths you’ll hear put out about renewables – that we can’t store the energy and thus renewables can’t be relied upon.
The first proposal involves taking Loch Morar, a freshwater loch 300m deep, but one just a few hundred metres from the shores of Loch Nevis (salt water). The plan would be to build a dam 280m high across a narrow pass to the North, which would allow an upper reservoir to be created 300m high. Water could then be pumped in either direction to create 600m of head and provide up to 1,800 GWh’s of energy storage. By comparison, the UK’s current storage capacity is about 30 GWh’s.
And if this proposal seems a little oversized, there’s what…
