Twin Disc, a NASDAQ-listed company based in New York, has acquired Katsa Oy, a Finnish gearbox and power transmission manufacturer, for $23 million, aiming to expand its offerings in the European market with a focus on hybrid and electrification applications. Katsa's revenue of approximately $36 million in the fiscal year ending in September 2023 adds to Twin Disc's portfolio of products. In the realm of hydrogen fuel-cell technology, Honda and Hypermotive are collaborating to test the X-M1, a modular hydrogen fuel-cell power unit designed for marine applications like yachts and workboats. This partnership marks a significant step towards achieving carbon neutrality in the maritime industry. Additionally, Germany-based Höpen group is venturing into emissions-free technologies, including hydrogen fuel cells, following its separation from Becker Marine Systems. Through its subsidiaries eCap Marine and Lehmann Marine, Höpen is making progress in developing solutions like the Cube and Cobra energy storage systems and the H2PowerPac hydrogen power generator. Lehmann Marine's energy storage systems have been deployed in various vessels, including the workboat Chicago and Acta Marine's offshore supply vessel Coastal Liberty. The successful type-approval from class societies DNV and RINA further validates the reliability and efficiency of these systems in providing emissions-free propulsion energy for maritime operations.
