From YouTube replies @Aleksandrs Naumovs I forgot to mention PPAs. The utilities are entering into power purchase agreements with solar and wind contractors for per kWh rates that are lower than conventional thermal power plants. These often include short term 4 to 8 hour storage. Any new generation has to compete against renewables plus storage

This Youtube video Engineering With Rosie interviews a chemical engineer who talks about the problems of replacing some or all of the natural gas with hydrogen. Hydrogen has higher energy per unit weight, but it is much less dense than methane so it has much less energy per unit volume. The natural gas system has

From FB group TSLA Shareholders De Bits Said, “…analysts … are focused on million mile battery which is moot if not irrelevant.” To you, Mr. De Bits, it may be irrelevant because you are apparently clueless about how important the lives of batteries are going to be for the V2G – vehicle to grid –

From FB reply I’ve read there is research about feeding seaweed to livestock to reduce methane. The livestock industry has had manure digesters that produce enough power to run the dairy farms, and this is a mature technology. They could also run the farm equipment using compressed methane AKA natural gas. In any case the

If the old cells were made easier to take apart and reassemble it would be helpful. I think that someday the battery makers may do what Eagle Picher did for batteries on spacecraft. There is a container of electrolyte inside the battery. To activate the battery a small charge blows the electrolyte out of the

This short story gives the price of a Lavo green hydrogen fuel cell system as AU$35,000, I’m assuming it’s Australian dollars. It says the system is good for 30 years. https://amp.9news.com.au/article/4cb3ebca-0515-419a-b298-ee491bbccb2f Here is JHAT channel’s video about it. Skip first 2 mins. https://youtu.be/0_bTjcjqN6c A comment in the above video said this (quote): << owmid 6rgy.

Article says the coal miners are finally admitting there needs to be change. Coal power plants are uneconomical and must be retired. https://electrek.co/2021/05/06/coal-is-losing-the-price-war-to-wind-and-solar-faster-than-anticipated/
This 43 minute YouTube video is about solving renewable energy storage. It is mostly in Dutch with English subtitles. This is a very innovative pilot plant that uses basalt rock to store high heat. After the 30 minute point they interview the guy who explains that the Siemens Gamesa system they developed can replace the

Here’s a TED read. It’s extremely important that the world cut CO2 equivalent emissions in half by 2030 and continue dropping after that. For the US it’s now at about 51 gigatons per year, and this needs to drop by half to 25 gigatons per year. The electricity sector needs to decarbonize in order to

https://www.theguardian.com/australia-news/2021/apr/25/insanely-cheap-energy-how-solar-power-continues-to-shock-the-world Quote: “We’ve got to the point where solar is the cheapest source of energy in the world in most places. This means we’ve been trying to model a situation where the grid looks totally different today.” ” This rapid radical reduction in the price of PV solar is a story about Chinese industrial might
