The article itself provides the data to argue that it’s sensationalist.
Hydrogen is therefore an indirect greenhouse gas with a global warming potential GWP of 5.8 over a 100-year time horizon. A future hydrogen economy would therefore have greenhouse consequences and would not be free from climate perturbations.
If a global hydrogen economy replaced the current fossil fuel-based energy system and exhibited a leakage rate of 1% then it would produce a climate impact of 0.6% of the current fossil fuel based system. If the leakage rate were 10%, then the climate impact would be 6% of the current system
P.S.
Nobody in their right mind will spend energy to manufacture a gas and then let 10% of it leak out unused.
Leak rates characteristic of fossil gas systems are related to the nature of fossil gas systems.

it’s all a sham anyway. no one in their right mind will build an infrastructure reliant on cryogenically chilled liquid hydrogen, we can barely manage gasoline without fuel and oil getting everywhere, now we need to keep it supercold and pressurize the delivery?
have you seen gas stations? keep in mind, Lockheed had to develop spark proof switches and electrical systems, spark proof tools, all kinds of special equipment when they experimented with hydrogen powered aircraft and scrapped it because the fuel was too low density and too difficult to work with on large scales.
I mostly agree. I have seen a local hydrogen gas station and they had to invest a lot in safety measures.
I don’t see hydrogen as a viable street transport fuel.
However, I think it could be a viable stationary turbine or ship fuel, and a viable ingredient for synthesized methane or synthesized alcohols (provided that a cheap input of CO2 or CO is available).

Cali, norway, japan or south korea?

this is feasible. I’ve also seen ammonia suggested as an intermediary, but think we need the full court press of possible options for heavy lift operations like this. We’re seeing a whipsaw in temps because of our move from sulfate rich heavy fuel oils, but keeping this shit out of the atmosphere needs to maintain a priority. try everything for fuck’s sake, there’s gotta be something better.
also sea ops have the advantage of distilling hydrogen from seawater instead of *‘blue hydrogen’ barfff
Estonia. And it’s probably the only one in the capital, with two more in the country. Nothing serious so far, folks are just experimenting a little. There’s supposedly a fuel cell powered self-driving minibus somewhere, but I haven’t seen it.

TIL! At least they’re trying stuff out.
True, but also hydrogen is notoriously difficult to contain, as it diffuses even through metal. This still seems sensationalist at best
