Climate change policies

The amount of energy produced by burning green hydrogen is less than the amount of energy consumed to produce it.

If you're using green electricity to produce the green hydrogen then it doesn't matter as you're not adding any extra carbon to the atmosphere at any point.

 

[stavros]

In the budget, the government pledged more money for green hydrogen.
I do not know much about green hydrogen, but I do know that is produced using elecrricity. The amount of energy produced by burning green hydrogen is less than the amount of energy consumed to produce it.

Someone may correct me, but I think hydrogen's attraction is as a storage medium. As renewable generation doesn't correlate with peak demand, hydrogen could allow storage of excess at times of high production, to be distributed to the end users when they require it, removing, or at least reducing, the need for a fossil fuel base load.

They say it has to be pressurised for storage and the energy required to do so is too much.

Perhaps it would be easier to pump water uphill, then let it fall back over turbine blades at times of high demand.

That requires two storage reservoirs, one at a significantly higher altitude. These require a means of impounding the water, and that is usually a concrete dam [when the height is significant] or a large clay bank, but there's concrete in those as well. [see the dam at Kielder Water as an example]
Producing concrete has a large carbon footprint.

Also, the UK doesn't have a large number of rivers suitable for HEP or sites for pumped storage schemes. For the UK, most of better sites for the latter are already in use, several others have been proposed.

Absolutely any form of energy transfer or storage will have losses. Not really fair to pin this criticism on hydrogen alone.

I don't remember either candidate mentioning the subject on the campaign, but I suspect yesterday's events have greatly increased our chances of utterly fucking our only planet.

Shamefully it wasn't an issue. Trump doesn't care and Harris was too timid to bring it up.

But we know what Trump will do. We have his first term to judge him by. He will rip up federal environmental legislation and give tax breaks to polluters. Trump is a disaster for the world in this regard.

And he'll do all he can to get drilling, for oil and shale.

 

[StoneRoad]

Trump will also pull out of the Paris Accords ... that was one of his actions during his previous stint.

The world's pretty much fucked already, the orange buffoon will just cement that into stone, and push us all well past the temperature "tipping" point.

[Wish the next hurricane lamps Malingerer's Largo, with him in it.].

He'll accelerate what was probably going to happen eventually, regardless of who was in office anywhere. The massive devaluation of one waterside Floridian property is only small consolation.

More broadly, and this could arguably be a separate thread, I'd like to see psychological thought start to shape policy. It seems the post-war free market ethos will not solve the problems, but how you undo the basis around which Western society, and a growing number of others, has been built for nearly 80 years? You can argue that it needs top-down autocracy, but on the other hand outside of China and other dictatorships that won't happen without electorate and demand for it.

How do you create happiness and satisfaction with less?

Why do you place the "free market ethos" as beginning after 1945? There was such an ethos before the Second World War, and for abour 30 years following that war capitalism followed a model of a much state regulation.
