Hydrogen for Marine
To achieve ‘green shipping’, Hydrogen technology shows the most promise to deliver a low-CO2 future.
Considering alternate technologies:-
- Batteries: Ships require a large energy buffer, resulting in a battery size which, with current technology, is too large, too heavy and too expensive. Additionally there are no means to charge such a battery during a port call (charging infrastructure and charging time).
- Photo-Voltaic panels: the ship’s surface is not big enough to even provide 10% of the required power.
- Wind energy: more interesting for slow sailing vessels. Deck space is challenging. Given only a projected saving of 10-30%, it falls way short of the IMO target of 50% GHG reduction.
- Nuclear energy: it is too expensive, currently not feasible to insure, and requires too many trained personnel to be cost effective on a commercial vessel.
- Bio fuel: quite simply, there is not enough biomass available and, unless all the processing plants use zero-CO2 energy, doesn’t reduce the nett CO2 enough to meet the 50% reduction target
Green Ammonia: as a fuel, it is toxic, has significant ADR complexity and produces more NOx during combustion;
Green Methanol: as a fuel, it is interesting but has drawbacks – it is toxic and has ADR complexity, it emits CO2 during combustion and it will be difficult to prove that original CO2 was captured from the air;
- Green DME: suffers similar drawbacks to methanol, in that it still emits CO2, the origin of which is difficult to verify as coming from carbon capture.
The HYDROVILLE is the world’s first accredited passenger vessel powered by hydrogen in a diesel engine. The catamaran is first and foremost a pilot project to test hydrogen technology for applications in large seafaring ships.
On a daily basis Hydroville transports CMB employees from Kruibeke to Antwerp during the rush hour to avoid traffic jams.
The vessel is fully classed by Lloyd’s Register and has sea-going capabilities.
At 19kts (2800rpm) in dual fuel mode, the engine saves:
- 58% CO2 compared to diesel mode
- 65% NOx compared to diesel mode
- 13% increase in thermal efficiency
- in the first year of operation, saved over 4000kg CO2 based on H2 consumed
The HYDROBINGO will be the world’s first hydrogen powered ferry. CMB and Japan-based Tsuneishi Facilities & Craft (TFC) will work together to build this vessel. TFC has experience in developing & building environmentally-friendly vessels, such as electric propulsion ships.
CMB and TFC will own the vessel 50/50. After delivery, the vessel will be deployed in the Japanese inland sea.
• ‘HydroBingo’ will fit the requirements of the gross tonnage class up to 19 tons.
• Capacity: 80 passengers.
• Refeulling is done with trailer via Ro-Ro principle. Maximum sailing speed of 26kn. Cruise speed will be between 18-22kn
Created from a joint venture between Windcat Workboats and CMB Technologies, the HYDROCAT vessel will provide crew and equipment transfers to support maintenance activities for offshore wind parks operated by Vattenfall
Excess wind energy produced by offshore windfarms can be used to produce clean, economical hydrogen. This hydrogen gas can then be used to power the dual fuel HYDROCAT vessel, minimizing the environmental impact of the operation and maintenance of the wind farm.
• Design is based on the proven and efficient WindCat MK3.5.
• Dual fuel capability diesel – hydrogen.
• The H2 storage is distributed over 3 locations.
• H2 refuelling of 200kg saving 1.9ton CO2.
• 2x1000hp in total resulting in a 30 knots max speed with 13,3t bollard pull.
• The Hydrocat is expected to sail end 2020
Tug boats use medium speed diesel engines which can be converted easily into a dual-fuel (hydrogen diesel) powered vessel, HYDROTUG.
Tractor tugs which are commonly used in ports, are suitable for this retrofit.
• The modifications to the vessel are minor and the new components are already proven in other industries (H2 tanks, valves, connectors, etc), therefore low risk to the owners.
• 400kg of H2 is stored in the aft compartment below deck. Each refilling saves the total emissions of 1 car during 1 year.
• This project can be an enabler for large H2 infrastructure in port areas.
• The vessel will be used by Port of Antwerp for its daily operations.
• The Hydrotug will sail by Summer 2021.
