Is this hydrogen made from green sources or natural gas?
Interesting question John. Our IdeaSpies Energy Editor told be today that hydrogen as an energy source currently costs 5 times natural gas though that cost is expected to decrease.
Our Climate Editor is hosting an online conversation for us tomorrow (Tuesday 23 March) at 10am. You and Tom are welcome to join it

Thanks Lynn, hydrogen manufactured from natural gas (without ccs) has the same emissions as diesel so would defeat the purpose of decarbonisation. As the article didn't trumpet it's green credentials, I was curious about the source.
The bigger challenge is that it takes 50 kWh of green electricity to produce 1kg of hydrogen and has poor round-trip efficiency compared to batteries. So assuming solar/wind get cheaper and it becomes more competitive against fossil fuels, it will struggle against batteries and most probably be pushed to niche applications.
I'm busy tomorrow! Would have liked to join, will it be recorded?
Yes John, the Climate Conversation today was recorded. We'll include you on the list to receive it.
