What we call heat pumps is completely irrelevant.
Even Shakespeare knew that.

Nations Aim To Zero Out Shipping Emissions By Midcentury Max Bearak 2023 Jul 06 NYTimes www.nytimes.com/2023/07/06/climate/cargo-ship-emissions-agreement.htmlCargo ships burn bunker oil, so thick it must be heated to liquify for pumping. The agreement is to replace these ships, over time, by those burning hydrogen or ammonia, hopefully so-called green products, i.e., produced without the use of fossil fuels.

Nations Aim To Zero Out Shipping Emissions By Midcentury Max Bearak 2023 Jul 06 NYTimes www.nytimes.com/2023/07/06/climate/cargo-ship-emissions-agreement.htmlCargo ships burn bunker oil, so thick it must be heated to liquify for pumping. The agreement is to replace these ships, over time, by those burning hydrogen or ammonia, hopefully so-called green products, i.e., produced without the use of fossil fuels. Given the challenges of storing hydrogen on ships, I suspect it will be better, for the time being, to use green hydrogen to catalytically upgrade the bunker oil. That way there is increased use of green hydrogen in shipping as well as cleaner burning fuels, without the non starters such as massive hydrogen tanks that displace valuable cargo space. The logical conclusion of this would be a transition to green LNG. I doubt the step from there to hydrogen will be made at all, barring some breakthrough in hydrogen storage - perhaps MOFs or hydride storage.

Special section of The Wall Street Journal on electrifying America, 2023 Jul 24. (Does not appear online, at least without a subscription).
Especially good summaries of the problems involved with electrification, with an emphasis on transportation.

The school example of a Pyrrhic victory. Those involved have conspired, wittingly or no, to effectively disable the nuclear revolution in the USA. They can congratulate themselves on tramping under the green shoot, proving the sceptics and stereotypes were right all along, and obliterating a new chance for nuclear power. Congratulations, murderers!

Catalytic combo converts CO2 to solid carbon nanofibers while offsetting emissions 2024 Jan 11 Phys.org techxplore.com/news/2024-01-catalytic-combo-solid-carbon-nanofibers.htmlThe carbon nanofibers are a useful concrete additive, storing the carbon for a long time. The process also produces H2 for the hydrogen economy. Process heat required is but 400 ºC, easily obtainable.
