Breakthrough in green
H 2 production at sea with vertical wind turbines Onestone Holdings has announced the successful production of green hydrogen on a ship equipped with innovative vertical wind turbines . This groundbreaking achievement represents a major leap forward in harnessing renewable energy sources at sea to create clean fuel , according to the company .
Onestone Holdings ’ approach utilizes ships equipped with vertical-axis wind turbines . These ships leverage satellite data to navigate to areas with optimal wind resources , maximizing electricity generation . The captured wind energy is then directly converted into liquid green hydrogen onboard , eliminating the need for complex and energy-intensive onshore infrastructure . This onboard production not only streamlines the supply chain but also minimizes energy losses , ensuring a highly efficient green hydrogen production process .
Beyond production efficiency , Onestone Holdings is pioneering a viable solution for transporting liquid green hydrogen . As a cryogenic liquid , green hydrogen requires continuous cooling to maintain its state . Onestone Holdings ’ ships with vertical wind turbines have the potential to generate sufficient green energy onboard to power the cooling system throughout transport , ensuring a truly sustainable solution from production to end use .
SoCalGas , EVOLOH project helps cut AEM electrolyzer production costs SoCalGas and EVOLOH have completed a joint research project that resulted in enhancements to the current electrolyzer manufacturing process and technology .
Overall , the enhancements achieved in the project could reduce the capital costs of the electrolyzer technology by approximately 25 % and could help make the cost of renewable hydrogen more affordable .
EVOLOH ’ s AEM is made with readily available materials and utilizes a roll-to-roll manufacturing process . This enables a shorter and more reliable supply chain as well as a lower-cost , rapid production process for electrolyzer stack development . The project was able to achieve a 15 % increase in hydrogen production efficiency to EVOLOH ’ s Nautilus™ series electrolyzer stack . The increased efficiency also helps extend the equipment lifetime of the stacks compared to traditional techniques .
SoCalGas ’ RD & D program helped fund the project and provided technical assistance with EVOLOH ’ s development of high-speed coating methods for AEM electrolyzers . The electrolyzer stacks are designed to be compact , modular , and are capable of being scaled up to 24 MW each , which makes them wellsuited for large-scale industrial applications .
The technology will soon be scaled up at EVOLOH ’ s new manufacturing Center of Excellence in Lowell , Massachusetts , with a goal of producing 3.75 GW per year by 2025 in electrolyzer stacks and up to 15 GW in 2027 . EVOLOH will also begin MW-scale testing at its new headquarters in Santa Clara , California , later this year .
