The cargo ship passes through the Atlantic Ocean and emits anything other than water vapor. In the middle of the trip, you need to replenish fuel with green hydrogen produced without fossil fuels. The wind generator depends on the maritime float equipped with wind energy. This is an example of that method Green hydrogen ship You can sail without the need for port stop and release greenhouse gases. Offshore Hydrogen generators are more realistic than thinking, as shown in the prototypes already tested in the open water. Here, we will explore this potential paradigm shift in maritime transportation.
How does a green hydrogen ship work?
It is important to understand what a green hydrogen is before digging deep. This is generated by electrolysis, a process that separates hydrogen and oxygen molecules from water using renewable energy. It can be generated using a green hydrogen to generate electricity through a battery or as a direct fuel source. As mentioned in the previous article, this gas is especially useful not only on heavy machines and vehicles such as agricultural tractors, but also on green hydrogen ships.
Green hydrogen ships are already real。 Since 2024, the San Francisco Bay has been the home of hydrogen -driven catamaran, designed to replace diesel -driven ships in the medium term. This pilot project contains ships You can move up to 500 kilometers Works for 16 hours Before fuel supply. Catamaran generates electricity using hydrogen fuel cells and releases only water vapor as a by -product.
Now, imagine the future where an electric ship uses green hydrogen as a navigation fuel. The port must be equipped with a hydrogen refueling station. However, green hydrogen comes from water and renewable energy, so you can use two abundant resources in the ocean using seawater and wind power to install an offshore hydrogen -produced plant. Early prototypes suggest that this technical approach is executable.
Fuel supply ship’s hydrogen plant prototype
As mentioned above, the pilot test of offshore hydrogen plants is already ongoing. One of the first prototypes was released by a French company that launched the first green hydrogen production plant. Seal huffIn 2022, we were 20 km away from the Atlantic coast of France. The hydrogen production capacity is 400 kilograms per day and a 1 -MW electro rizer, and in June 2023, it began to operate on a 200 -square -meter platform connected to the offshore wind turbine. The use of renewable energy to generate green hydrogen by electrolysis of seawater.
According to project developers, the platform has already demonstrated the ability to produce green hydrogen autonomously. When the test phase is completed, the purpose is to install plants that generate 10 MW energy from the Belgian coast by 2026.
There are other offshore green hydrogen projects designed for industrial and commercial applications in addition to the ship’s hydrogen generators. One of these initiatives is the H2HEAT project led by the PLOCAN platform and funded by the European program. This project produces green hydrogen for heating buildings and other buildings and supports the EU’s zero emission policy.
Regardless of its origin, green hydrogen may supply power to a wide range of transportation systems beyond hydrogen ships. As described in the previous article, hydrogen -drive trains and airplanes are also new alternatives.
