Europe's Spending Billions on Green Hydrogen. It's a Risky Gamble (www.bloomberg.com)

To be clear: we’re going to use renewable hydrogen for some things, such as fertilizer manufacturing — there isn’t any other way to do them sustainably. There are applications for which it’s one of the most expensive choices, such as home heating, and a whole host of industrial processes and aviation sitting in between.

MrMakabar,

Your bonus is for e-fuels, which is not hydrogen, but basically currently oil based fuels, like petrol, kerosin and so forth made from hydrogen and CO2 using electricity.

MrMakabar,

That would be red, unless you have something else in it. But it is actually about turning iron ore, which is basically dirty iron oxide, into pure iron:

Fe203 + 3H2 → 2Fe + 3 H2O

MrMakabar,

Add to that people of fighting age leaving Russia to not get drafted. The men dieing are the potential fathers of the next generation. We also saw what happens to birth rates and migration, when Russia is in an economic crisis. We pretty much know that Russia is heading towards another one right now.

MrMakabar,

Not necessarily. LNG prices have been falling to pretty much 2020 levels. So less profit. The other factor is consumers. The big ones are Japan, China, EU and South Korea. The EU has falling gas and LNG demand. China does not want to be depended on US LNG. Japans natural gas consumption has decreased every year but 2017, since 2014. For South Korea it looks like gas consumption might also fall.

So there is reason for hope.

MrMakabar,

First of all EVs do not need that much power. We are talking something like 25% more electricity production for a country like Japan. Then Japan has rather a lot of onshore and even more offshore wind potential. Mountains are a problem, but hardly something which can not be overcome. Solar can easily be installed on roofs and mountains are even less of a problem.

Also really important to say it. Combustion engines in cars are massivly inefficent. So an EV is still better for the climate, even if run with coal electricity. The other factor is that Japans population is falling. So they will need less power over the long term.

MrMakabar,

Social media in general loves controvery. So they push radical ideas, as they create conversation, clicks and other interactions, which means more time on the site. That then allows for more ad money.

The truth is most Americans are not that radical, due to just not caring too much about politics. They just want things to keep going as they are.

The other part of it is none Americans on social media. For Europeans for example Biden looks center right for the most part. Then again Europeans have options further left.

MrMakabar,

Meeting climate goals has to create an actual advantage for countries or well avoid them punishment from the international community. Blind cooperation is nice in theory, but it just does not work in practise. So we need proper funding from the wealthy countries, maybe leveraged from tariffs based on historic emissions, which then can go to poor countries, which only recieve the money, if they meet certain targets like stay below emission per capita levels or new fossil fuel infrastructure. At the same time we need to punish current emissions. For that systems like emissions based tariffs would work well. Other things can be done in trade agreements as well. I really like tariffs here, because they create a real monetary insentive for good action and that is kind of what works.

But be nice to China, otherwise they kill the planet is not going to work. Same story for the US and every other country on the planet. Nice words from politicans do not save the climate.

MrMakabar,

To be fair the biggest reason the region has a water problem is that the lignite mines upstream pump less water downstream and they are even starting to fill some of them up after the mining is stopped.

MrMakabar,

He got a point here and lets see what happens. German authorities have been way to hard on anything, which even smells a bit anti Israel. Especially Berlin is insane on this. When you start canceling jews for critzising what happens in Gaza right now, you really have a problem. Just to say it Yaroufakis is as far as I know not Jewish, but he also as far as I know ever called for the destruction of Israel as such, but the end of the illegal activities of Israel in Palestine.

MrMakabar,

Biden has actually stopped taking oil financing for his campaign. If you are not in a swing state, it is probably a good idea though to show that there is support for further left politics.

MrMakabar,

The simple truth is Biden has been the best president in lowering US emissions and his laws would lower it even more. So yeah, I believe that.

Also Biden has said that he will stop US arms deliveries to Israel, if Israel attacks Rafah. That is by far the most anti Israel thing, the US has done in decades.

And that is the thing. Biden actually improves a lot of things. That does not make him perfect, it does not mean he does as much or even as quickly as he should(as Gaza clearly shows), but Biden has been surprisingly good as a president. There are third party canidates, which are better then Biden, but given how the system works, voting Biden is a good choice in a swing state. In states, which are not swing states vote third canidate for sure, to show that going further left can win the Dems some votes.

MrMakabar,

Which still means that fossil fuel power plants loose money in those periods due to low electricity prices. Those low prices also lead to electricity storage and more electricity consumption. The later is good, when it replaces other fossil fuel consumption(usually that is).

MrMakabar,

There are basically three options to deal with overproduction:

  • export
  • storage
  • shutting it done

The cheapest way of using wind and solar actually includes shutting done some of it at excellent days, so the capacity is enough to provide enough power at just okay days. The other problem is that storage is an issue. Right now pumped hydro and batteries are the only ways we have economically somewhat able to actually store electricity economically and both are at the expensive end. So they are usually just used to balance the grid. Hence the optimum is more in having overcapacity. The other option is to use the water reservoir of large hydro river plants, to vary the electricity production. that works rather well. The other big one is exports. As soon as a grid is large enough(continent sized), the weather matters a lot less. So you might see a lot of hvdc lines going from your country to other ones being planned, built and finished.

However most of the world is not even close to that. At 30% and a lot of it hydro, renewable electricity production is mostly just replacing fossil fuel.

MrMakabar,

Vermonts electricity was 48% clean energy(renewables and nuclear). To go to 100% they need to add storage, a lot more renewable generation and upgrade the grid. All of that requires planning, ordering the parts and then building it. Doing it in a decade is a realistic, but ambitus target.

MrMakabar,

Oil companies usually do not, but electricity companies do. The problem is that oil companies are great in geology, drilling and chemistry. Geothermal is a similar skill set and chemistry can be used in other products, but the first is small business and the other not renewable nexessarily.
