Wärtsilä Marine and Hycamite have jointly developed a groundbreaking system for cost-effective production of hydrogen from LNG onboard vessels. This innovative approach aims to significantly reduce greenhouse gas emissions, including CO2 and methane, by utilizing LNG as fuel. Notably, when combined with bioLNG, this solution can even result in a negative carbon footprint. The system leverages the existing LNG infrastructure and, when integrated with Wärtsilä's LNGPac™ fuel gas handling system, enables the onboard production of hydrogen. This allows Wärtsilä's flexible, multifuel engines to operate on a blend of onboard hydrogen and LNG, thereby reducing the ship's CO2 and methane emissions. The process also yields solid carbon as a by-product, which is easier to store and manage onboard compared to traditional CO2 capture methods. This high-quality solid carbon can potentially be utilized in industrial applications, offering an opportunity for additional revenue generation. The system is designed to be scalable and modular, featuring automated on-demand hydrogen production, storage of solid carbon onboard, and compatibility with both new vessels and retrofits into existing LNG-fuelled ships. Furthermore, the system's capabilities align with EU and International Maritime Organization (IMO) regulations for 2050, positioning it as a crucial solution for the decarbonization of the marine industry. Mathias Jansson, the director of fuel gas supply systems at Wärtsilä, emphasized the significance of this development in accelerating the transition to carbon-neutral shipping. The collaboration with Hycamite not only addresses the lack of supply infrastructure for hydrogen but also enhances safety in hydrogen storage and handling while progressively reducing the environmental impact of marine operations.
