Hydrogen is actually a silver bullet - everything from seasonal energy storage to transport, power, heating, industry, plastics etc

The only reason he lobbies so extensively against hydrogen is to maintain the status quo; which means not just fossil fuels but the broader fossil-based economy
Batteries will never structurally change the energy system

So. In version 5 of the #HydrogenLadder jet aviation (ie medium/long-haul) is on Row B. In the footnote it says "as e-fuel or PBTL [power and biogenic carbon to liquid]". I now think they will be far too expensive. Hydrogen will be used in bioSAF production.

It's the *clean* hydrogen ladder, not the *green* #HydrogenLadder. We need to clean up the top row, but the economics of doing so with green hydrogen are simply unaffordable. Not to mention that each kWh of green power you use to make hydrogen could have 2-9x the impact if used directly.

The goal is decarbonisation, not electrification.
Electrification is a method !
Use cases with big impact on decarbonization:
Steel
Transport
As alt. for electricity made by coal.
Using H2 for fertiliser is bad use case

Replacing natural gas to make fertilizer is not.

Paywall. There is lots of hydrogen underground, but I have seen no evidence it can be extracted, at sufficient purity, with sufficient flow rate, for a sufficient time, near enough to a source of demand, to be worth doing. There might be some local use cases. Doesn't change the #HydrogenLadder.

Just to revisit the #HydrogenLadder again, we see much of his predictions appear very optimistic (e.g., batteries and biofuels for literally *everything*)
Very interested to see how he is going to square this circle, although (surprisingly) #bluehydrogen does not seem to be off-limits

Thoughtful thread. I switched from thinking that trials of hydrogen for trains and other use cases on rows DEFG on the #HydrogenLadder were so obviously stupid they should be abandoned. Now I love to see them go ahead (though not with my money) because only failure after failure will kill the dream.

..yet $280bn in pledged hydrogen subsidies are still being delayed by 'policy groups' and lobbyists like Michael Liebreich who maintain the fossil fuel monopoly, and ensure that emissions keep rising

In case green H2 is available:
Ranking is needed to define use green H2 to maximize decarbonization:
High in ranking: Heavy duty transport, Steel, Replacement electricity by Coal (all those -18kg CO2/1 kg H2)
Low in ranking: Fertilisers (only -9kg CO2/1 kg H2)
(different result #hydrogenladder)

I like your #hydrogenladder much more that the one of Liebreich.
Mine would be different but similar.
The focus is to decarbonize.
So in my opinion we need two ladders:
1. for electrification:
In that ladder f.e. cars are high, also trucks, steel, heat pumps.
since with less kWh ..

No I don't *favour* green hydrogen. Why should I? I favour the best clean technology to do any particular job in the economy - hence my #HydrogenLadder. But I also favour not wasting green electricity making #hydrogen when it can have 3 to 9 times more impact through direct use.

We are talking past each other. We agree on the need to decarbonise hydrogen used as feedstock - the top row of my #HydrogenLadder. But you keep ASSUMING it has to be done with renewable hydrogen, and I keep EXPLAINING why that is costlier than other approaches and has an emissions opportunity cost.

The #HydrogenLadder does not say anything about how much of anything we do, or whether it's growing or shrinking, or a valuable activity. It just says whether we are likely to be using clean hydrogen for it or not, once the #HydrogenSoufflé has collapsed.
