Re: Cop26
32 million cars in UK
Assume (it will never happen) that they were all replaced by 100% electric vehicles? Country wide total blackout as 32 million cars will take about 1.5-3x the total grid supply to charge at just 3.7kW (single phase home charging is 3.7 to 7kW) and a car battery is what, 100kWh so a nominal 24h to charge (usually the battery will not let you touch the last 10% or it faces destruction if really run totally flat) from 'empty' to full. Without taking into consideration any other e-vehicle type (vans, busses, lorries etc). That's not including all the usual electricity consumption. We simply don't have close to the capacity available to cope with that full stop, the answer? Hydrogen fuel cells in cars, meets the general city air quality targets but is nowhere close to carbon neutral (joke words) ever or just stick to burning petrol/diesel. |

Generally in the UK we are a net importer of everything grown, we simply don't have the landmass to 'grow our own' biofuel. Electrolysis of seawater using offshore wind farms and supplying the Hydrogen back to shore for storage imho is a far better solution (However living near a Hydrogen Storage area would leave me with the screaming heebie-jeebies every time i see a naked flame). All I can be sure of is it looks like I'll see the death of the loud/noisy motorcycle in my lifetime |

its about time we stopped making guns and started getting along. hydrogen does not have to be stored in liquid form it can be stored as a powder which as far as i know is not as volatile as its liquid counterpart. people moan about E10 when we should be praising it and asking for more ethanol to be added like the E85 in california. if we all do that then crude will last 4 times longer so instead of 50 years we will have 200 years to find a solution. |

Re: Cop26
Hydrogen can stored as a metal hydride but that process is in its infancy.

Re: Cop26
lets face it its not as bad as it was during the age of coal and steam.
if we really want to save the planet then how about population control. one child per married couple. and yes they will have to be married to have children and even if they get a divorce they are still not allowed to have more children... less people less burning of fossil fuels... simples. round my area pretty much anyone who turns the age of 17 goes and passes their test so that ends up around 5 cars per household coz they bread like furkin rabbits. i said find a solution i did not say we have to use fossil fuels for that amount of time. even just taking away gas will cause chaos never mind making all the vehicles on the road electric. |

Re: Cop26
Someone on reddit pointed out this link to an article on large (undeclared) methane leaks
https://www.space.com/satellites-dis...hane-emissions Methane is a much more "efficient" green house gas than carbon dioxide but has a shorter atmospheric life (it oxidises into CO2 and water eventually).

Biofuels have dubious green credentials (depending on how they are made, it varies) but the sheer quantity needed to compare with oil is insane. |
