Crucially, the system can produce hydrogen at pressure, simplifying downstream compression and widening its industrial utility.

Are other electrolysers not able to generate hydrogen under pressure? From my rudimentary understanding of electrolysis, it is unclear to me how or why pressure would impact electrolysis.

Hydrogen still accounts for under 2% of Europe’s energy mix, and much of it is produced from natural gas

This is still baffling to me. There are many articles about how solar and wind farms have to cut off their electricity because they generate too much of it. The solution to me seems obvious: generate hydrogen, don't let it just go to waste. I have a few guesses why but would love to be able to speak to operators of those farms and hear it straight from them.
