Yes a better price - but we get 30 days to pay with our usual lot which makes life easier.

Interestingly Electrical CO² emmissions don't seem to be much offset by wind turbine power? i.e Mains gas produced less?
That's what makes a nonsense of all the talk about Hydrogen. The plant is claimed to be around 60-70% efficient, well actually they said "hoping to reach" that efficiency. You can see why, all those pumps, two separate compressor stages, and huge cooling plant guzzling energy and dumping heat to the atmosphere. It might be OK if they could run solely on surplus wind power, but the plant takes time and energy to start and stop, so really needs to run 8 - 10 hours at a time.
This makes Hydrogen around 0.33kg carbon per kWh.
Yes it is all nonsense - peddled by the people who are determined to make wind power work even though there is still no sensible way to store the energy. The same people who seem to think batteries are the answer. Trillions are being wasted on this nonsense and people wonder why our bills are so high

No breakthrough or new technology occurs without trial & error. At least they are investing to try & improve matters.

With just a hint of a profit motive.

Precisely. Global warming be damned, unless there's money to be made from it.
Personally I think the error is in concentrating on the source of energy rather than energy saving. The attitude seems to be it doesn't matter how much energy you use as long as it's electric. That's why even small electric cars have 150hp motors.
I worked in the energy management business in the '80s, and the bottom absolutely dropped out of the market round about 1990. No interest whatever in energy saving. Now it's back under the carbon guise, and now cost again. But we have lost nearly 30 years when we could have been improving.
The problem with batteries is they haven't advanced that much in 100 years. Most cars still use a normal lead acid. Forklifts and submarines the same. When it comes to cost v capacity lead acid is still the winner and they haven't changed. Yes lithium are lighter for the same power but weight isn't really an issue for storage.

The waste heat you mention might be used for commercial & domestic heating and crop greenhouse heating etc similar to secondary heat reuse from Germany's power stations . Obviously heat some will be lost but a lot could be recovered , fresh water fish and salt water fish farming along with all manner of factory food farming production might also be beneficiaries . It's early days yet in this quest of as many alternative useful energy sources as possible so we are no longer reliant on one type or one source of supply .
When you think about it , changing the energy out put into food production is actually a way of storing energy for several years or more .

Not quite right , in 1988 we had roof void insulation and cavity walls filled with blown rock wool fibre , we also put in all CFL's in place of incandescent lamps. In 1993 both our rearing sheds were given a 100 mm interrnal coating of sprayed expanding poly urethane insulation foam .
All over East Anglia and Lincolnshire new buildings industrial commercial and domestic ones were being well insulated from at least 1988 till I stopped working in 1995 and .
All of the Peterborough new town builds of some 65 thousand houses were insulated to the latest grade . 1995 onwards out in the Fenland industries all new or renovated commercial buildings had to have building regulation compliance wrt insulation .
Come our move here to Wales June 2005 there were already government assisted insulation grants & schemes in place mainly for green renovations but a while later for domestic dwellings
Glaubers salts can be used for massive heat stores , I seriously looked into having a 20,000 litre insulated tank store of it back in 1992, siting the collectors & a buried insulated store in the railway bank we owned where our home was. Unfortunately I got crippled due to people failing to do their job properly at my day job earner and had to give it up and move to a bungalow.

If you listen to their propaganda you'd think they do.

To the Earth's core? Geothermal! I like where you're coming from.Have you thought about drilling a well ?.....

Read the article..intriguing. Might get some Glaubers (if possible) just to experiment with for personal academic interest. I remember someone I knew building a heat storage water tank in his greenhouse floor.That was 50yrs ago, way-before solar became
Trouble nowadays is everything is a desperate effort to try to lessen the impact of 200yrs of population explosion due to the (benefits) of fossil fuels. We're addicted to hydrocarbons. Perhaps we can be weaned off them over the next 200years?

Still 10p a litre more than I paid early December.
