Norway's Hexagon Purus Maritime has recently secured a purchase order for a $2.75 million compressed hydrogen fuel system for a sustainable ship commissioned by Greenpeace, operated by Spain's Freire Shipyard. The vessel, designed by Dykstra Naval Architects, will be a hybrid integrating sails, battery packs, solar panels, hydrogen, and e-methanol systems, highlighting a commitment to diverse power sources for sustainability. Guillermo Freire, the managing director of Freire Shipyard, and Robert Haugen, the managing director of Hexagon Purus Maritime, expressed enthusiasm for pioneering zero-emission technologies. Haugen identified challenges in hydrogen usage in the shipping industry, emphasizing the need to address high production costs, infrastructure limitations, and safety concerns. However, he remained optimistic about transitioning to greener energy alternatives. The article mentions the increasing focus on green hydrogen as a significant energy source by 2050. Despite current challenges, initiatives like the Inflation Reduction Act are expected to facilitate the transition to renewable energy solutions. Additionally, the article highlights positive developments, such as the deployment of hydrogen storage tanks for a hydrogen-powered ferry in San Francisco and the use of methanol in a green shipping corridor between Rotterdam and Singapore. These advancements align with the International Maritime Organization's target of achieving net-zero greenhouse gas emissions by 2050. The maritime industry's shift towards sustainable solutions and the adoption of alternative fuels like hydrogen and methanol reflect a positive outlook for reducing emissions and combating climate change.
