Thanks to the organiser, this was an interesting one to watch. The world of #hydrogen start ups is...weird. My observations below. https://twitter.com/corporateknight/status/1324838952835174407

@MarceloRochaLu1 from BASF introduces methane pyrolysis. Certainly appears to be most energy efficient, but I reckon it can only work in presence of a large offtaker of carbon black byproduct. Currently, that's not a huge market. Still one to watch.

@hydrogenLOHC is enthusiastic about the future of hydrogen, using demand assumptions of 500 TWh/yr by 2050 for Germany. That's about five times my own prediction.

But anyway, hydrogenation round trip costs 21kWh/kg, or 54% of H2 energy content. Significant.

Proof energy, a fuel cell start up, claiming batteries are not up to task in medium and heavy duty EVs.

But their battery assumptions are the sort of stuff @AukeHoekstra debunks regularly.

Here, another start up, Keyou, which produces hydrogen combustion engines.

How to make a battery alternative look more expensive? Cell density: 100 Wh/kg, cost 500 eur/kWh. Also, the bus has to charge on residential electricity rate while hydrogen gets producer rates.

There is a lot of hype around hydrogen still. Don't skip on due diligence.
