Bureau Veritas Marine & Offshore (BV) has granted an Approval in Principle (AiP) to LATTICE Technology Co., Ltd. for its innovative design and development of Lattice Pressure Vessel (LPV) tanks and liquid hydrogen (LH2) fuel gas supply systems for onboard ship installations. The LPV tanks feature an internal lattice structure that evenly distributes pressure, allowing them to handle pressures exceeding 30 barg. This design reduces the space required for gas storage while maintaining cargo volume, offering benefits for cryogenic and medium-pressure environments. The LPV's innovative design also minimizes strain on the tank, reduces dynamic loads, and improves operational stability. Additionally, the scalable design optimizes space utilization by up to 50%, leading to cost savings in fabrication and reduced auxiliary equipment. Liquid hydrogen (LH2) propulsion systems are highlighted as a promising solution for emissions reduction in the shipping industry, as they produce zero direct emissions. This technology aligns with the industry's goals of mitigating environmental impacts and reducing greenhouse gas emissions. The adoption of LH2 propulsion is seen as a significant step towards a more energy-efficient, sustainable, and future-proof shipping industry, paving the way for a greener maritime sector.
