The maritime industry is constantly seeking ways to reduce its greenhouse gas emissions and meet sustainability goals. One potential solution gaining attention is the use of liquefied hydrogen gas (LH2) as a zero-emission fuel. However, with limited experience in the marine sector regarding LH2 bunkering, there is a pressing need for clear guidelines and safety considerations.
The Maritime Technologies Forum (MTF), a collaboration between flag States and classification societies, has released a report addressing this issue. While the International Maritime Organization (IMO) is already working on guidelines for ships using hydrogen as fuel, these guidelines will primarily focus on ship installations and stop at the bunkering manifold.
The MTF report highlights several key observations regarding LH2 bunkering. Firstly, the properties of hydrogen, particularly its extremely low temperature, mean that experience gained from liquefied natural gas (LNG) bunkering cannot be directly applied. Additionally, the bunkering process for LH2 will be more complex, requiring strict limitations on the presence of nitrogen to prevent system freezing and clogging. The use of more insulated components and piping will also be necessary.
The report emphasizes the importance of vessel-specific procedures for bunkering operations, including the development of more automated procedures. Crew training and certification will play a crucial role in ensuring safety, given the added complexities involved in LH2 bunkering. It also recommends updating Safety Management Systems to address the unique safety aspects of LH2 bunkering.
Alf Tore Sørheim from the Norwegian Maritime Authority and Knut Ørbeck-Nilssen, the CEO of DNV Maritime, both stress the significance of these guidelines in supporting the safe bunkering of liquefied hydrogen. As of now, there are no international standards specifically covering LH2 bunkering. However, the MTF suggests that ongoing developments and experiences, such as those gained from the Norwegian ferry MF Hydra, could serve as a basis for creating guidelines and recommendations.
The MF Hydra, the world’s first hydrogen-powered ferry, has been operating since March 2021. With an 80 cbm hydrogen storage tank, it can accommodate up to 300 passengers and 80 cars while significantly reducing carbon emissions.
In conclusion, the development of international standards for LH2 bunkering is essential to promote safe and efficient operations in the maritime industry. These guidelines will facilitate progress towards a more sustainable future, where hydrogen plays a crucial role as both a marine fuel and a cargo.
Frequently Asked Questions about Liquefied Hydrogen (LH2) Bunkering in the Maritime Industry:
1. What is LH2 bunkering and why is it gaining attention in the maritime industry?
LH2 bunkering refers to the process of fueling ships with liquefied hydrogen gas as a zero-emission fuel. It is gaining attention as a potential solution to reduce greenhouse gas emissions and meet sustainability goals in the maritime industry.
2. What guidelines have been released to address the issue of LH2 bunkering?
The Maritime Technologies Forum (MTF), a collaboration between flag States and classification societies, has released a report addressing the guidelines and safety considerations for LH2 bunkering.
3. What is the role of the International Maritime Organization (IMO) in LH2 bunkering?
The IMO is working on guidelines for ships using hydrogen as fuel. However, these guidelines mainly focus on ship installations and do not cover the bunkering process.
4. What are some key observations highlighted in the MTF report regarding LH2 bunkering?
The report emphasizes that experience gained from liquefied natural gas (LNG) bunkering cannot be directly applied to LH2 bunkering due to the different properties of hydrogen.
