we’re kicking off proceedings at the 1st green ammonia consortium international symposium in tokyo. 🇯🇵

(ammonia is emerging as a likely carrier for the international trade of hydrogen.)

sadly this is one of the few photos i will be allowed to post.

200 attendees, ~10 presentations and lots of networking.

good to see a number of australians here.

“green” ammonia is derived from renewable energy. (not to be confused with blue ammonia, derived from gas and includes carbon capture and storage).

a key initial use will be the co-firing of ammonia in coal power stations — helping to reduce the CO₂ emissions intensity of japan’s power fleet.

research is ongoing into using ammonia as a fuel in gas turbines.

other uses for ammonia include:
• fuel cells (for power)
• industrial furnaces (ie. fuel for heat)
• marine engines — MAN is developing marine propulsion engines that run on ammonia.

very soon we will have an option for zero-emissions shipping fuel.

we’ve just got presentations out of the way from 3 gas companies who shall remain nameless but hail from australia, the netherlands & norway.

sadly, all 3 tried to push “blue” hydrogen — produced from gas + carbon capture and storage — claiming that we can’t scale renewables.

great to see #AndrewDickson of @CWP_Renewables presenting the asian renewable energy hub project.

at full scale 9.9Mtpa of green ammonia — price stable, secure supply of fuel with zero carbon risk.

ammonia is “the next LNG”.

now up, #AttilioPigneri, the founder of australia’s H₂U — “the hydrogen utility”.

H₂U has a pipeline of 4 green ammonia plants and believes that green ammonia is already viable.

now listening to IHI, a resources and energy engineering and product firm with 30,000 employees, US$15bn annual sales.

IHI is developing processes to co-fire ammonia with coal, reducing coal usage.

has already achieved 20% substitution in small plant. currently aiming for 60%.

…also working on using ammonia in gas turbines — has already achieved 20% co-firing on 2MW commercial gas turbine.

…also working on using 100% ammonia in a fuel cell. 1kW trial successful. by capturing the heat, efficiency greatly enhanced.

just heard from NYK, a major shipping line. they absolutely see a future where their ships are fuelled by ammonia.

ammonia carriers being fuelled by (a small fraction of) their cargo.

NYK is a member of the “getting to zero coalition” — committed to developing commercial deep-sea vessels by 2030.

they believe that ammonia will be competitive with very-low sulphur fuel oil (VLSFO) before 2030.

ie. zero carbon shipping is on the horizon.

…and it’s a wrap.

so exciting to see so many major companies committed to decarbonising the power & transport sectors with green ammonia.

a strong collegiate atmosphere… and an impressive australian presence.
