The Norwegian-German classification society DNV has given the green light to a concept for an electric-powered hydrogen tanker from a group of companies led by HD Korea Shipbuilding & Offshore Engineering (HD KSOE).
DNV announced that it has granted Approval in Principle (AiP) for the concept of an electrically-powered liquid hydrogen tanker that could enable the storage and transportation of 80,000 cubic meters of LH₂.
The AiP award ceremony is to take place at the Gastech trade fair in Houston. The concept is described as a “milestone as part of a wider collaboration”. Partners involved included HD KSOE and energy company Woodside Energy, as well as shipping groups Hyundai Glovis and Mitsui O.S.K. Lines (MOL) from Japan. The collaboration is aimed at developing an integrated value chain for the large-scale maritime transportation of liquid hydrogen, according to the statement.
The ship is equipped with new large liquid hydrogen tanks from HD Hyundai, which are reportedly characterised by “advanced vacuum insulation and an electric propulsion system with Hydrogen Dual Fuel HiMSEN engines”. They are designed to enable the flexible use of diesel and hydrogen. According to the partners, the specially developed hull design and cargo handling system should also enable greater operational efficiency and commercial flexibility.
DNV: “Another important step”
With the AiP, DNV now confirms that HD KSOE’s electrically powered LH₂ carrier concept basically meets the safety, environmental, and technical standards required for the safe and efficient transportation of LH2. The class also conducted detailed hazard identification (HAZID) and environmental impact identification (ENVID) studies, which are critical to assessing and mitigating potential risks associated with the design and operation of the electric LH₂ carrier.
Vidar Dolonen, DNV Regional Manager for Korea and Japan, emphasised: “The AiP is another important step towards building a global hydrogen economy through safer and more efficient long-haul transportation of LH₂. DNV is honoured to be involved in this project and support the development of cutting-edge energy solutions.”
Chang Kwang-pil, Chief Technology Officer of HD KSOE, said: “This AiP is an important confirmation of our commitment to developing a reliable and cost-effective LH₂ carrier. Achieving this goal will require a concerted effort across the LH₂ shipping value chain and we are committed to making progress through continued collaboration and innovation.”
Julie Fallon, Woodside’s Executive Vice President Technical & Energy Development, said: “Thanks to the investment and combined efforts of all stakeholders, we have made significant progress in developing cost-effective and flexible supply chains for shipping liquid hydrogen at scale to meet the needs of our customers.”
