Re: Another grid scale battery approved
I plonked in ”BESS capacity in the UK?” as a search in Goggle. It says 4.6GW (end of ‘24) as first hit and a few hits later it says 3.4GW is operational, as at April this year. Obviously there's a large discrepancy and maybe the truth lies somewhere between those reports. Duration and typical SOC r...

Re: "Kinetic Hydro"
This device is more like a wind turbine than a hydro turbine. The below equation discusses how much energy is present in a given area. There is then an "efficiency" limit of how much energy you can extract from the moving fluid (theoretical limit is around 60%). https://www.e-education.psu...

Re: Making Methane in Swindon
I have a friend who owned a plant nursery. The dutch growers make big improvements in yields by adding CO2 to the greenhouses. But when he looked at buying CO2 in the UK, he found it was really expensive! Unless you happen to be located next to somewhere that produces clean CO2 as a by-product, it ...

Re: State of the offshore wind jobs market
Given how many gigawatts have secured leases in scotwind and INTOG, it's probably a pretty safe job market.
I imagine contract roles are a bit more tricky. I'm a consultant, and we seem to be pretty busy.

Re: Energy/Business politics: Gas storage capacity
That's sounding like an argument for increasing domestic supply.

Re: long duration storage with liquid air
3. Long Duration Energy Storage is basically a technology that can discharge for hours (in excess of 4 hours seems to be the definition). I understood "long duration" in this context to mean inter-seasonal storage. Eg saving solargenerated energy in summer to use in winter! The government...

Re: long duration storage with liquid air
I am going to refrain from giving another Physics lecture. Just mention a few factors folks might want to look up) 1) The critical temperature for O and N (the temperature above which both will remain gasses regardless of how high the pressure) 2) Whether pressure vessels "scale" or not (...

Re: long duration storage with liquid air
Yes, it looks good. Maybe a more extreme version of the experimental Compressed Air Energy Storage which is being buit at Carrington? It's unfortunate/ironic that their air tank has a big capital "H" on it though - I know what it made me think of! It's also good that at last this Cap and ...

Re: Grid forming Batteries - mimicking spinning reserve.
I’ve never understood why we still need a “spinning reserve” that is an actual, physical, spinning mass. Surely all the solar/battery inverters in people’s houses as well as at grid-scale batteries can do the job? Is this another wheeze by the FF companies to keep the hydrocarbons flowing? Spinning...
