I've just read this:
www.bbc.co.uk/news/business-54841528
If you are talking about energy storage you need to specify two parameters. On is the amount of energy stored, measured in MegaWatt hours (MWh). And teh other is how fast it can deliver this energy - aka the power. This is specified in MegaWatts (MW)
In this piece, which describes a liquid air energy storage plant, the nearest it gets to this is the following paragraph
"The 50MW facility near Manchester will store enough power for roughly 50,000 homes."
The strange unit 'homes' varies from piece to piece and journalist to journalist and is therefore meaningless. In this case it seems to imply one 'home' = one kilowatt, but even if we take this as the truth, the really important parameter is for how long the 50,000 homes will be supplied with this 50MW. A day? An hour? A minute? Your guess is as good as mine as nowhere is this mentioned. You might think, as I do that as £10 million of your and mine money has been handed over to the company building this establishment that this might be of some interest, but you won't get it from this piece. For those interested, I looked it up andit can allegedly store 250MWh so will support 50,000 homes for five hours maximum.
This piece of journalistc stupidity I find extremely irritating. It is like saying the cost of a car is "Ten" without specifying whether its dollors, pounds, hundreds or thousands of either. Utterly meaningless.
Why can't journalists grasp the simple difference between energy and power and the units used to specify them? For god's sake its not that bloody difficult is it? Back in the days when nobody bothered about energy and where to get it from it may not have mattered much, but these days it is a major subject and these stupid should do better to inform us, or if it really is too hard, to stand aside for someone who can..
