Sustainable aviation fuel (SAF) project with BioTfuel technology including thyssenkrupp Uhde's PRENFLO gasification technology and Axens' GASEL technology

While green hydrogen and green ammonia promise to be important clean energy carriers in future, there are significant challenges to be overcome not only in production storage and transport, but also financially realising the project. Innovate technology from thyssenkrupp Uhde, embodied in standardised, pre-integrated, modularised plant can deliver low cost of ownership and de-risks execution.

M.J. Cousins of Johnson Matthey and K. Nölker of thyssenkrupp Uhde discuss the integration of LCHTM technology and the uhde® ammonia process in providing low carbon ammonia at scale, efficiently, reliably and safely today.

Risk analysis tools such as hazard identification (HAZID), is often a first step in broader risk management and is especially valuable for green ammonia, where new technologies and processes introduce novel risks. This article explores various aspects of HAZID, from the basics of hazard identification to unique considerations specific to green ammonia facilities.

A European ammonia plant, has successfully restarted following a revamp of the process gas cooling section, executed by Casale. Casale replaced the outdated boilers located downstream of the secondary reformer with three new double-tube type boilers supplied by Arvos. The new boilers were installed in the same location as the previous ones, minimising investment costs and plant modifications. The more robust and reliable design of the Casale-Arvos boilers has resulted in enhanced overall performance and reliability of the ammonia plant.

Paralloy has developed Omega technology, an advanced reformer tube design that enhances heat transfer, gas turbulence, and process efficiency. Dr Dominique Flahaut of Paralloy explores the real-world implications of Omega reformer tubes.

Esben Sørensen and Glenn Rexwinkel of Plug Power review the safety aspects of integrating hydrogen production by electrolysis into existing ammonia processes. Novel safety risks associated with such changes are surmountable and the analysis presented shows that green ammonia production can be no more hazardous than traditional ammonia production.

The partners in the HyLion network are planning to produce low carbon hydrogen from renewable energy in Scotland and convert it into methanol for use as a low carbon fuel in the shipping, aviation, and motorsport sectors in the UK and Europe. The HyLion project partners include ARUP, McPhy Energy, Bosch, E.On, CO2 Recovery Ltd, Mareneco Ltd, Cadeler A/S, and P1 Fuels. Management and IT consultancy MHP is providing strategic and operational advice on the development and digitalisation of an efficient supply chain. Around 9,000 t/a of hydrogen and around 45,000 t/a of green methanol are planned in the initial pilot plant, which will use 63,000 t/a of biogenic CO2 from E.On’s biomass power plant at Lockerbie and from local whisky distilleries for the production of methanol. Hydrogen will come from an 80 MW electrolyser supplied by McPhy Energy, using local wind energy, with pure water being supplied using Bosch technology. P1 Fuels’ technology will convert e-methanol into an e-fuel that fits seamlessly into the existing fuel infrastructure and offers a decarbonisation solution for the automotive industry, international and national racing series, and light aircraft, for example. Another customer for the e-methanol will be the shipping company Cadeler A/S. The plant is expected to start production at the beginning of 2028.

In part 5 of this series on stripper efficiency issues we conclude the discussion with a focus on fouling inside stripper tubes.
