@mateialexandrucoltoiu7207 - “they must use carbon capture…” Australia must use Carbon Capture, but that is OK because carbon is needed in everything (ie plastics, fertilizer, roads, roof shingles, vinyl floor planks, batteries, etc.) so whoever has refined carbon will have an amazing opportunity to become a natural resources exporter of the future. Japan sees Hydrogen to completely eliminate carbon fuel imports, which is huge for them, especially with China being the proverbial 1000 lbs gorilla in the room.

@calmeilles - “Australia… carbon capture” Of the current 114 hydrogen-related (Industry) projects in Australia, over 80 announced renewable hydrogen projects. Australia tracks their current projects, many are green hydrogen export projects. Australia understands their use cases: - to blend with (or replace) natural gas for homes, industry and cooking - for fuel cells to generate electricity to power cars, trucks, buses and trains - to store energy and generate electricity for mining sites and remote communities - as an industrial chemical feedstock for products such as ammonia, fertiliser and iron - to trade clean energy with other countries Oz has the potential to be a heavy lifter in this energy arena.

This is certainly not the first H2 ICE engine. In recent time, back in 2003, Mazda RX-8 RE combusted gasoline as well as Hydrogen. Car was shipped with Hydrogen & Gasoline tanks: 210hp @ gasoline, 110hp @ H2. It had regenerative breaking, 144v battery, engine shuts off instead of idles, and electric turbo for low end torque.

14:30 - “Really low efficiency” But if H2 has greater energy than batteries, ICE low efficiency is less important. As long as H2 can be provided at a price point competitive on a TCO cost for the car & fuel/charge… that is all that matters

@alterbart7916 - “carbon dioxide… has no use” On the contrary, Carbon must be harvested in liquid (oil), solid (coal), or gaseous (natural gas) form, using expensive mining methods. CO2 collected in an easy to harvest containment system provides endless use cases of a reasonably safe gas… into any other substance. Plants, for example, turn CO2 directly into sugar, with a little sunlight. When excess CO2 is pumped into a plant containment system, plants produce more sugars, and plants grow faster. CO2 can also be used to produce fuels through combining with hydrogen. CO2 can be used to produce biodegradable plastics. Carbon has 4 bonds, making it incredibly useful. Whoever has CO2 reserves will do well, in a future economy. Whoever extracts CO2 from the atmosphere will find themselves saving the planet, if the Global Warmies are correct.

13:34 - “not really much of a charge network” Filling/Charging is far more efficient for H2 vs EV Far fewer H2 stations will be needed to be built, since Electric Charge stations will have to keep vehicles there to charge longer than H2 will take to fill.
