TotalEnergies has signed an agreement with the German developer RWE to supply 30,000 t/a of green hydrogen to the Leuna refinery for fifteen years, beginning in 2030. The green hydrogen will be produced by a 300 MW electrolyser, built and operated by RWE in Lingen. Green hydrogen storage will be provided locally. The green hydrogen will be delivered by a 600 km pipeline to the gates of the refinery and will prevent the site’s emission of some 300,000 tons of CO2 beginning in 2030. This is the largest quantity of green hydrogen ever contracted from an electrolyser in Germany.

The Port of Açu and renewable fuels company Sempen have signed a contract to reserve an area in the low-carbon hydrogen hub at the port, in the north of the state of Rio de Janeiro, for the construction of a green ammonia plant. The projected facility would have a production capacity of 1 million t/a of green ammonia. A final investment decision (FID) is expected for 2027-2028, with production of the first green ammonia beginning in 2030.

lomarlabs, the innovation arm of Lomar Shipping, has announced a strategic collaboration with Newlight, a technology company specialising in hybrid hydrogen-diesel engine retrofits, to accelerate the adoption of cost-effective, lower-emission solutions for the shipping industry. This collaboration will focus on retrofitting conventional diesel engines to operate on a hydrogen-diesel mix, reducing fuel consumption on average by 20% and significantly lowering greenhouse gas emissions. Savings of up to 30% have already been demonstrated in workshop trials and this new collaboration will seek to replicate this onboard vessels.

Mitsubishi Heavy Industries is developing a low temperature ammonia cracking technology (HyMACS™ ) that leverages exhaust heat from existing sources, such as boilers, steam turbines, engines, and heating furnaces. This innovative approach, which also includes the development of more efficient membrane separation technology using molecular sieves for hydrogen purification, is designed to offer a more sustainable, reliable and cost-effective pathway towards hydrogen production.

Common risks of ammonia cracking as a new technology and how these risks can be recognised and mitigated by applying an innovative approach of the technology maturation process is described as seen through the eyes of an end user/investor. Addressing those risks is pivotal to enable end users to choose the best technology for their needs. Albert Lanser of Duiker Clean Technologies discusses some of these risks and how they have been addressed in its novel technology for producing the lowest levelised cost of hydrogen via its unique ammonia cracking process.

NextChem compares KPIs and overall costs to evaluate the performance of several low carbon (blue) hydrogen production technologies. A detailed comparison of SCT-CPO, SMR and ATR technologies is reported.

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.

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.

KT-Kinetics technology has signed an $125 million engineering, procurement, construction and commissioning (EPCC) contract to build a hydrogen production unit at Petronas’ Pengerang Biorefinery, Malaysia. The hydrogen plan is expected to be operational by the second half of 2028, and will supply up to 38,000 normal m3 /h of hydrogen for the production of sustainable aviation fuel (SAF) and hydrogenated vegetable oil (HVO). NextChem will license its NX ReformTM technology for the unit. The new biorefinery will process approximately 650,000 t/a of raw materials such as used vegetable oils, animal fats and waste from the processing of vegetable oils to produce sustainable aviation fuel (SAF), hydrotreated vegetable oil (HVO) and bio-naphtha.

Trammo, Inc. and ExxonMobil signed a heads of agreement to advance discussions for Trammo’s long-term offtake of 300-500,000 t/a of low-carbon ammonia from ExxonMobil’s Baytown, Texas facility. The facility is expected to produce virtually carbon-free ‘blue’ hydrogen with approximately 98% of CO2 removed, and will use this low-carbon hydrogen to make low-carbon ammonia. Trammo, a leading international physical commodity trader, will leverage its market and logistical expertise to deliver and sell in Europe and worldwide this unique low-carbon ammonia for use as fertilizer feedstock and for other key industrial applications.
