Energy Matters Global and Domestic

Only after too many guinesses Gibbo!!

No, none.

I followed this map and there were lots on Teesside.

I don't think anywhere had planned blackouts in the UK last winter.

[bobins]

National Grid enacted their 'Demand Flexibility' service on a couple of evenings last winter as electricity supply was getting a bit tight. This requires / requests consumers reduce their electricity usage - depending on contract terms and/or domestic or commercial. It's virtually impossible to state whether this actually averted any power cuts, but I'd reason they didn't take this step unless they thought it necessary for whatever reason.

Candle makers will be cursing the no blackout news

[Peter.N.]

I bought a very old but efficient Lister generator on the strength of that news - but have never had occasion to connect it up.

It's strange that people are worried about blackouts yet in South Africa it's 4 hrs on then off etc. 1st world problems...

Watched that this morning Steve, Dave's definitely back, enjoyed his presentation, and an interesting topic. Loads of innovation going on all over the world and in this case not just at the research stage, but flow batteries being used.

Back in 2022 I put a list together of the various storage options featured on this thread with the conclusion that a range of tech will emerge. Bit long so its in the spoiler, and the area is constantly developing.

Spoiler: show

A few column inches from the archives about storage, and yes I can see Hydrogen being used as a storage medium under those circumstances, possibly even the most likely. The round trip efficiency nowhere near as good as batteries but better for longer term storage.

This post from the Hydrogen thread covers the ground on Hydrogen as a storage intermediary in grid storage.

Through the pages of this thread many examples have been reported, together with many informative vids from the likes of justhaveathink, and fully charged on the various storage options from grid scale batteries, hydrogen storage, and liquid air, to old coal fired power stations, large battery storage, hot rocks, molten metal, liquid air , gravity, flywheels, pumped hydro, flow batteries etc. etc

Round trip efficiency from electricity in to electricity out, capital costs, useful life , duration time and capacity for storage, frequency of charge/discharge, and expected number charge-discharge cycles all will most likely result in a mix of storage options evolving.

Energy storage equally important as energy generation in any Energy Security Strategy.

Brief recap on what has been considered on the pages of this thread, and a new one which does a bit of a summary at the start

I wish I could just read this, can't stand the presenter.

[mickthemaverick]

Another month lower than the previous 4 years but ongoing likely to be similar to the previous year as the energy measures we took began last September with the LED lamps throughout and the introduction of the gas kettle!!

The UK government is stumping up £36 million ($41.4 million) to help support a green energy project that aims to use waste heat from a datacenter to keep nearby homes warm.

According to the newly formed Department for Energy Security and Net Zero (DESNZ), the scheme will be located in the boroughs of Hammersmith and Fulham and Brent and Ealing to the west of central London, and will connect 10,000 new homes to nearby datacenters to use waste energy for heating.

The project is being developed by the Old Oak and Park Royal Development Corporation (OPDC), and will also connect 250,000 m2 of commercial space to the same heat network.

The Register

Just what they were doing with the waste energy from the combined electricity generating station/waste incinerator where I lived in the seventies.

A bit waffly and undeniably an Octopus promotion but some interesting points.

[NewcastleFalcon]

Refreshingly positive. I started a thread to find out more about Heat pumps back in April 2021, which to date has run to 10 pages of information and comment. More and more companies will jump on the bandwagon, manufacturing will increase volume and unit price will drop.

Just for completeness I will copy that vid into the heat pumps thread which recently I have only sporadically tended.
