A daily reminder:
Climate Change is a CO2 problem. We will not solve it without drastically cutting fossil fuel emissions.
@TatianaIlyina Green hydrogen and methan is the way to go, i am sure. Produce green electricity, produce green fuels. Maersk just invested 9 billions to power their ships with it in the future.
@Albert_Hubble @TatianaIlyina How is producing **Green hydrogen** any efficient or cost effective?
It take either Natural gas or ultra clean water(highly in demand) plus a of of energy to produce hydrogen.
Its overly complicated/costly to store and transport and then to converted back to energy it's an overall efficiency of 30%
@voidabyss @TatianaIlyina I am sure you know better than for example Maersk who is investing 9 billion in the production of bio ethanol and amoniak. You think they won't calculate how expensive it is? In the good regions of the world solar energy is down to 1 cent per kilowatt. And facilities will only become more efficiant. of corse it won't happen over night. You won't run big ships with batteries, neither will you replace gas power plants with batteries. https://www.maersk.com/news/articles/2022/03/10/maersk-engages-in-strategic-partnerships-to-scale-green-methanol-production
@Albert_Hubble That's called greenwashing and you didn't bring any scientific argument other then parroting Maersk's marketing material.
Don't take the big polluters words at face value and go look up scientific facts and research.
> But, for now, many of the companies pushing hydrogen aren’t doing so to save the planet. They’re doing so to save their business models in a time of extreme transition towards greener technologies and e-mobility.
@voidabyss They are doing it because otherwise you won't be allow shipping in Europe in the future. And how is it greenwashing when you use green electricity. What is your solution to this if going for green electricity and green fuels isn't the way? Shipping goods will not stop anytime soon. Containerships are already the most efficiant way to ship goods.

in the short term natural gas (cleaner then diesel fuel) can be used to power shipping vessels. https://www.econnectenergy.com/articles/how-do-lng-ships-work
Renewable energy used directly to supply the electric grid reducing coal and gas/fuel powered stations, mid to long term deploying small nuclear electric power stations replacing gradually fossil fuel power stations(see France as example).
The energy transition need to happen gradually and using technology that is robust, efficient and cost effective. Drastically cutting fossil fuel, just create inflation, food starvation and societal turmoil.
I am pretty sure that green hydrogen will have some industrial application for reducing carbon emissions, but as an energy storage it's not efficient nor cost effective no matter how much the polluter industry want to promoted and green washed.
@voidabyss Look, this picture is more than a decade old, and i am not going to write a third time what green fuel is and what not.
@Albert_Hubble
I know what you mean by "green fuels" I hope a decade from now you see a "Green Hydrogen" powered container ship, but I am as skeptical about It as you are about nuclear energy. 🙂
@voidabyss I just don't belief in nuclear anymore. Theay already can't produce electricity to competitive prices. Flamaville for example is like 10 years late for 3 x the price. And the 4th gen nuclear is nowhere to be seen. But we will see it in the future. I would bet my money on green fuels any day instead of nuclear.
