[QUOTE="Bruce_ma gooshvili, post: 1104782, member: 74121"] Excellent video for anyone with an interest in future energy production / energy independence. Kind of depressing and in conjunction with other videos by this guy can be summarised as: - heat pump installation can be pretty expensive compared to alternatives regardless of whether heat pump prices reduce (probably worth a survey / quote to see if you are one of the lucky ones that that that easily as the other options may be worse long term) - any form of hydrogen production other than being produced by renewables, is pretty much terrible for the environment and potentially more expensive than gas. - We can actually produce 'green' hydrogen from renewables at a rate of 70-80% which is way better than what I thought. - hydrogen cannot pass through existing gas pipe network. Would be an eyewatering £130 billion upgrade for UK. - to supply the whole UK with green hydrogen would take roughly, 4x the electricity of universal heat pump usage (such is the energy efficiency of heat pumps) - the no-brainer use of hydrogen is to produce it during off peak renewable times (nighttime), store it, then burn it to produce electricity during periods of low wind (replacing the current role of gas producing 40% of UK electricity). This might be an option to transition via until govenrments get their crap together over battery farms. Kind of worryingly the SNP (in government with Greens) seem to be wanting to go down the 'hydrogen boilers' route. [MEDIA=youtube]vwkANJME3Ok[/MEDIA] [/QUOTE]
