A new route for phosphates?

I am writing this freshly returned from the Sulphur Institute’s annual Sulphur World Symposium in Florence (for more on that see pages 24-25), where one of the topics causing some excitement was the anticipated commissioning of a demonstration plant for Travertine Technologies’ new Travertine Process. The plant is due to be commissioned at the Sabin Metals site near Rochester, New York in mid-2025 at a cost of $10.7 million. Capacity is put at “hundreds” of tonnes per year of gypsum processed, and removing “tens” of tonnes per year of CO 2 from the atmosphere.

Green hydrogen to decarbonise Leuna refinery

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.

Hybrid hydrogen-diesel retrofits for greener shipping

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.

Ammonia ship completes demonstration voyage

Japan’s New Energy and Industrial Technology Development Organization (NEDO) says that the world’s first commercial-use ammonia-fuelled vessel, Sakigake, has successfully completed a three-month demonstration voyage, during which the vessel engaged in tugboat operations in Tokyo Bay, while achieving greenhouse gas (GHG) emission reductions of up to 95%. The vessel was completed by Nippon Yusen Kabushiki Kaisha (NYK) and IHI Power Systems in August 2024, in cooperation with Nippon Kaiji Kyokai (ClassNK) as part of a Green Innovation Fund Project. NEDO says that the vessel will continue to be used for tugboat operations in Tokyo Bay, and the organisation will continue to promote research and development of next-generation fuel vessels, including developing an ammonia-fuelled ammonia gas carrier, in conjunction with NYK, Japan Engine Corporation, IPS, and Nippon Shipyard. This vessel is scheduled to be delivered in November 2026.

Merdeka Battery to build new HPAL plant

Indonesian nickel miner Merdeka Battery Materials (MBMA) and partners have signed definitive agreements to construct a high-pressure acid leach (HPAL) plant on the Morowali industrial park, Sulawesi. The unit will have a nameplate capacity of 90,000 t/a of contained nickel in mixed hydroxide precipitate (MHP). PT Sulawesi Nickel Cobalt (SLNC) will construct and operate the plant adjacent to the existing HPAL plant operated by PT Huayue Nickel Cobalt (HNC). SLNC will source and process laterite nickel ore through a 20 year commercial agreement with MBMA's SCM mine, starting from the commissioning date. An ore preparation plant will be built at the SCM mine to enable ore transportation via pipeline to the SLNC processing plant at IMIP. The total combined investment for constructing SLNC (including interest incurred during construction) is expected to be approximately $1.8 billion according to Merdeka. Construction of the project commenced in January 2025 and is expected to reach commissioning stage within 18 months.

Liquid Wind to progress abandoned renewable methanol project

Liquid Wind has announced the development of a new 100,000 t/a green methanol project in Örnsköldsvik, Sweden, in collaboration with local energy company Övik Energi. Övik Energi’s combined heat and power plant in Örnsköldsvik was due to be the site of Ørsted’s FlagshipONE project, which was slated to produce 55,000 t/a of green methanol from 2025. A final investment decision (FID) was made in late 2022 when Ørsted bought out Liquid Wind’s 55% stake in the project, but the Danish offshore wind company chose to discontinue FlagshipONE in August 2024.

Worley to provide FEED for green ammonia plant

Worley says that they have been selected by First Ammonia to provide front end engineering and design services for a new green ammonia facility in Victoria, Texas. This facility will have an initial anticipated production capacity of 300 t/d of green ammonia. First Ammonia also says that it will be the first in the US to use solid oxide electrolyser technology (SOEC) for hydrogen production, which are 30% more energy efficient compared to conventional electrolysers.

TotalEnergies to decarbonise its refineries in Northern Europe

TotalEnergies has signed agreements with Air Liquide to develop two projects in the Netherlands for the production and delivery of some 45,000 t/a of green hydrogen produced using renewable power, generated mostly by the OranjeWind offshore wind farm, developed by TotalEnergies (50%) and RWE (50%). These projects will cut CO2 emissions from TotalEnergies’ refineries in Belgium and the Netherlands by up to 450,000 t/a and contribute to the European renewable energy targets in transport.
