SOEC - THE green hydrogen solution

100% efficiency...thats really amazing.....complete conversion of electricity to H2....fantastic HT

[@sunlaser6587]

I call bullshit on that one. Pure marketing more or less. Nothing is 100% efficient. ur lucky to get 90 on a large scale. Maybe they got up to 98 or 95 in lab but no way they got it on a megawatt scale, on longer periods of time that would actually be viable. Bet there is a reason why they are not yet selling them to every wind farm. (and i don't think that this is due to ppl not interested)

It's complete bull maybe 99% at the very best.

[@angellestat2730]

​@@Virtueman1 electrolysis can reach up to 125% efficiency if you measure from the electrical input, they reach 100% because they are using waste heat as external energy input, usually that waste heat comes as steam at 150c. Heat reduce the electricity required to split water.

@@angellestat2730 funny definition of efficiency in that case

[@angellestat2730]

​@@Virtueman1 if you can get the waste heat for free as it happen in most cases of cogeneration and your cost depends on the electricity that you use, then not sure why is wrong to measure the efficiency from the electrical input which is what would define your cost of production. In fact.. even PEM electrolysis at ambient temperature requires less electricity than doing the same at lower temperatures. A lot of process does not measure the overall efficiency from all parameters who contribute to that reaction or process. They are not lying either, they are showing they are taking waste heat from industrial process.

Hi. For water solid oxide electrolysis. Do I need to input 600oC steam or the electrolyzer heats up with electricity?

[@user-pt1ow8hx5l]

Bang on target, the video! Thanks.

[@abhishekpandey21790]

Are you ready to commercialize it on gigawatt scale ?

Checkout Bloom Energy !!!!

"...All electricity and heat generated in the stack".... As I know an electrolizer inputs electricity and water and outputs hydrogen and oxygen. How come stacks generate electricity? Out f what is electricity generated in a stack?
