Following an apparent revival of the Spirit of Ireland on Monday, it’s now Organic Power‘s turn to look into pumped hydro to store electricity, using salt water and the Atlantic Ocean as the lower reservoir. I have not changed my mind during the week or indeed the year, but Organic Power works at a more realistic scale than Spirit of Ireland; Organic Power works with experienced people; and it is does not seem to be looking for public subsidies.
Best of luck to them. Let’s hope their current investigations spring a surprise.
