He thought that when wind turbines are curtailed they store the energy for later. He was wrong, obviously, thats how Andy rolls.Interesting. We only have one pumped storage unit in the UK as far as I know. It's been around for some time. It needs a big hole in a small mountain. It purpose is taking up surges as it can react extremely quickly giving plenty of time to get a generator up and running if needed.
TV and kettles surges - it's good at handling that.
Many seem to accept that wind needs storage and that is costly. This is very probably why countries are leaning towards nuclear which can be arranged to produce variable outputs. Any excesses could also be used for hydrogen but liquificaton needs even more power. As some are now pointing out with LNG. It's done by cooling to rather low temperatures.
