Everfuel, Shell to collaborate on a large-scale hydrogen plant in Denmark

In Denmark, hydrogen infrastructure developer Everfuel Denmark A/S and A/S Dansk Shell – the Shell Refinery in Fredericia, and partners have entered into strategic cooperation on the future supply of the transport sector with green energy in the form of a hydrogen plant. The ambition is to be able to install the largest of its kind Power-to-X (P2X) plant in Fredericia to store and utilise excess wind power.

Located in Fredericia Harbour, the Shell refinery was opened in 1966 and has the capacity to refine 3.4 million tonnes of crude oil per annum. According to Dansk Shell, the refinery refines around 35 % of all fossil fuels in Denmark. The company has entered into a strategic collaboration with Everfuel for a green hydrogen plant on site (photo courtesy Dansk Shell).

With the cooperation, it is now possible to apply for Danish Energy Agency funding through the energy storage fund pool. The ambition is to be able to install a Power-to-X (P2X) plant in Fredericia with up to 1 GW of electrolysis capacity, but the start could be 20 MW.

According to Everfuel, this is an important step in the green transition, which enables green power to be combined with flexible green hydrogen production, so that wind power can be saved from when it blows to when energy is needed.

Largest green hydrogen plant in the Nordics

The plant is to be built by Everfuel and located on a site owned by the refinery. The Shell Refinery is already using hydrogen as an important part of the production process and will be able to reduce the largest share of hydrogen production. This will make the refining processes of the refinery greener.

The collaboration will establish the absolute largest hydrogen plant of its kind in the Nordic countries, which among other things will prepare the refinery to match the requirements for green liquid fuels. This will be done, for example, by being able to store and utilize large amounts of wind power, which thus makes the liquid fuel greener.

The plant and its large-scale production of hydrogen could thus provide the basis for supplying green hydrogen to the transport sector, both as an energy carrier in liquid fuels and for direct use in hydrogen-powered vehicles.

At full extension, the hydrogen plant will have a capacity equivalent to the refinery hydrogen demand being converted to renewable energy, as well as supplying up to 4 000 fuel cell buses and trucks with hydrogen daily.

In the first phase (2022-23), Everfuel intends to build a 20 MW electrolysis plant and a central hydrogen storage facility that will be able to provide the necessary buffer that fluctuating renewable energy production requires.

The hydrogen storage will have a capacity of 10 tonnes, which corresponds to five days of refinery demand or up to 170 000 km in a hydrogen bus/truck.

A green transition pathway for Denmark

The project aims to demonstrate a way forward in the transformation of the Danish energy supply chain based on renewable energy. The companies highlight that with the falling prices of offshore wind, the potential for further expansion of wind power in the North Sea is considerable, 10- 100 GW of potential.

The expansion of wind and solar in Denmark has come so far that converting the electricity produced into something usable is a growing challenge. In order to integrate the green power into the Danish energy system, it is crucial to consider systems such as Everfuel’s P2X, which can convert electricity into usable gases and liquids.
