It should be noted that Fortescue Metals is not some disinterested third party here. They have a massive stake in green hydrogen production (see their FFI division).
Hydrocarbons (not necessarily from fossil fuels, see https://prometheusfuels.com/ https://prometheusfuels.com/) + DAC are one proposed alternative to green hydrogen for powering industries (such as mining) where batteries are not a good option. I know experts who believe this is more viable.
I still agree with him that DAC can't be used as an excuse to keep emitting.
- dauertewigkeit 3y agoSynthetic hydrocarbon fuels depend on both green hydrogen and DAC. So green hydrogen would be needed anyway. The only question is whether you build infrastructure with the goal of using hydrogen directly or not.
- elil17 3y agoSynthetic hydrocarbons would likely not use much of FMG's hydrogen technologies: membranes, hydrogen liquidification, hydrogen vehicles, etc.
- dredmorbius 3y agoIt should also be noted that many of the most vociferous advocates of CCS are of or aligned with the fossil fuels industry, whether direct producers or major consumers, particularly electric utilities (especially those reliant on coal), and hard-to-substitute activities such as air and marine shipping. For the latter, petroleum-analogue synfuels seem to me a far more viable option, along with a shifted economics (higher cost curve) of the sector --- air travel and long-distance shipping are likely to be rather more expensive by and by.
