Germany is installing Europe's largest battery. :flan_cheer:

500 MWh, to be ramped up to 3 GWh. Iron flow. Pumping electrolytes between two tanks.

Sounds good - Turn off a coal power plant. Install a giant liquid battery. Connect it to solar panels.

This is a fairly dry table of gas storage in the EU. It's interesting.

Sweden has 0,1 TWh gas stored - literally nothing.

Germany has 188,5 TWh and that's 75 %

Everyone else is in between, except Belgium who forgot the gas storage. It will be fine. 0 TWh in the summer is normal. Worst case one can buy a few bottles from France (69 TWh) for the winter.

Some oil and gas countries can't see any scientific evidence that the world need to phase-out fossil fuels. :blobcatfacepalm:

☢️ Nuclear is going great 🙃

Two new reactors in USA are only seven years late and 17 billion dollar over budget

Maybe it's time to invest in renewable energy?

🌞 Today is the summer solstice 🥰

It reminds me about Milankovitch cycles

They trigger the beginning and end of glaciation periods (Ice Ages)
🌍 = 🥶 🥵 🥶 🥵 🥶

Here are three animations explaining them

A state in Germany found that battery trains are better than hydrogen trains.

They are buying 102 battery trains to replace their diesel trains.

Maybe batteries wins over hydrogen for all land transport?

It's going well on COP28 🙂
"More than 100 countries have now signaled support for a fossil fuel phase-out."

They track methane emissions by satellite and tell the oil companies where it leaks.

USA want to cut methane emissions with 80 %. Nothing can stop that, except the election next year.

This is a H2 fuel cell. They put two of these hydrogen fuel cells inside a regular Volvo truck.

1000 km range, up to 65 ton vehicle, fill the tank with green H2 in 15 minutes.

JohanEmpa, 7 months ago to australia

Just saw that some trucks in Australia drive two 800 km round trips per day with a total weight of 175 ton in one of the directions.

I believe a regular 40 ton truck can be modified with 1-2 extra fuel cells and five more H2 storage bottles and that will cover it.

Am I right?

SSAB plan to reduce CO2 emissions with ~90 % around 2030. That's more than 8 million tonnes. Sweden's total emissions can reduce by around 10 % and Finland's by around 7 %.

They're doing this 15 years earlier than originally planned.
