Turbomachinery News Network: Aalo Atomics, Turboden America, KHI, and more

Welcome to the 37^th edition of the Turbomachinery News Network. I’m James Cook, associate editor at Turbomachinery International.

Aalo Atomics contracted Baker Hughes to supply a 10-MWe steam turbine generator set and associated auxiliary systems for the power island of Aalo-X, an experimental nuclear reactor. Baker Hughes will deliver the steam turbine by year-end 2026, assisting Aalo Atomics with developing one of the first advanced reactors to power a data center. The companies began collaborating on the Aalo-X power island after the order was placed in Q4 2025.

Kawasaki Heavy Industries and Kobe Steel announced the operational start of a next-generation hydrogen fuel supply system for hydrogen-based power generation. Additionally, the duo began the world’s first supply of hydrogen fuel to a power generating facility using an intermediate fluid vaporizer and a liquefied hydrogen pump capable of pressurizing above its critical pressure. KHI will improve the efficiency of its fuel supply system while Kobe Steel develops an IFV that utilizes cold energy derived from liquefied hydrogen.

Turboden America was selected by Tallgrass to supply three waste heat-to-power organic Rankine cycle plants at gas compressor stations in Columbus, OH, Chandlersville, OH, and St. Paul, IN. The WHP units will each supply approximately 10 MW of additional clean electricity for rural utilities—recycling turbine exhaust heat into baseload, grid-stabilizing power. The projects will also be supported by Turboden’s cloud-based AI monitoring system, Turboanalytics, to provide anomaly detection, predictive maintenance, and forecasting.

Everllence PrimeServ signed a long-term service agreement with TVO to conduct the intermediate maintenance of emergency generator units and execute monthly performance tests at TVO’s Olkiluoto 3 nuclear power plant. The four-year LTSA covers dismantling, cleaning, reconditioning, parts replacement, and reassembly with a maximum completion time of 30 days per unit.

German ferry operator TT-Line said its Ro-Ro passenger vessels Nils Holgersson and Peter Pan successfully operated on bio-LNG during 2025, achieving significant emissions reductions while maintaining engine performance. The 230-meter vessels, commissioned in 2022 and 2023, are powered by two 8L51/60DF engines and two 6L51/60DF engines each. They operate in the Baltic Sea between Germany, Sweden, Poland, and Lithuania.
