You certainly notice more solar in the corner of fields during train journeys. In addition we are seeing heavier industries collaborating to get into renewable supplies for their fuel. Attached link to Scottish distilleries as a catalyst for green hydrogen project. shfca.org.uk |

Sorry - I might have asked this before. I'm confused by storage capabilities being quoted in MW rather than MWh. What do they mean by a 57MW storage facility?

There are at least 5 solar farms within a 4 mile radius of where we live, and a planning application for another

Not much solar here and most domestic wind installations get refused by planning...

Thornton is MW the storage of volume (power) and mw/h effectively the speed of discharge (capacity).

I have friends who have hydro, two valleys from here, it is amazing! But... You need a lot of fall, which they have and I don't...

Storage surely is MJ, and speed of discharge MW? W=J/s

I would have expected to see it expressed as storage capacity of x MWh that can be supplied at a rate of y MW

TR you are correct, but the vernacular, particularly in the media all talk about *peak* power output, not storage capacity. This is a hangover from central load thermal power plants (e.g. coal, gas, nuclear) for which, usually, the MW and MWh meant more or less the same thing. As we move to *intermittent* or *variable* source energy providers, then the distinction between power and capacity is critical - the media hasn't caught up yet. |
