Why do you need to store gravity, it’s not going to run out. Is it?
I thought it was cool that we have a Scottish company chosen to work with the developers of this interesting project in Finland.
Cracking journalism as always though:
> The gravity energy system would be able to store 2MW of power
Unfortunately that doesn’t really tell us how much energy can be stored.
I don’t know how many similar deep shafts there are in Scotland that aren’t full of water, but it would be great if this turns into something useful anywhere, and the supply chain is based here, in part.
I am not trying to start an argument but what makes a company “Scottish” and not “UK”?
I understand the difference for people, but what is the meaning for a company?
Doesn’t all the tax and laws flow from U.K.?
Meh. I had a Meccano wall clock like fifty years ago that ran on gravity power, aka potential energy. Just like those grandfather clocks all did.
Makes sense though. Dinorwig, aka Electric Mountain is a pumped hydro power station. That does exactly the same thing by pumping water into a mountain lake with cheap/surplus electricity and using it to generate at peak times. That is definitely a gravity battery.
Gravity batteries store very little energy. They almost make hydrogen look like value for money.
Surprised you can get enough energy out of dropping weights – so should be interesting to see how this goes.
Bit of a niche system though – can’t be that many deep holes suitable for this!
Neat idea
Central Scotland’s riddled with old pit works, so if this can be made to work on a smaller scale, I could see it being adopted widely
This is complete bollocks and a waste of everyone’s time. Assuming a 100 ton weight and 500m shaft, that’s 500,000 kJ, or about 140 kWh. That’s a bit more than 2 car batteries?
There’s a good reason the only ‘gravity batteries’ that work are pumped storage hydropower which can rely on the weight of a whole body of water to generate/store energy.
