Evaluating conversion of natural gas to hydrogen

Statoil, Vattenfall and Gasunie have signed a Memorandum of Understanding (MoU) to evaluate the possibilities of converting Vattenfall’s gas power plant Magnum in the Netherlands into a hydrogen-powered plant.

The potential CO2 emission reduction is 4 millions t of CO2 per year. This is equivalent to emissions from more than two million cars.

The next steps will involve feasibility studies to evaluate the conversion of one of the three Magnum units of Vattenfall Nuon in Eemshaven to run on hydrogen. The units are operated by the company’s Dutch subsidiary. In addition, Gasunie examines which infrastructure for transport and storage is needed.

The scope of the MoU also includes exploring how to design a large-scale value chain where production of hydrogen is combined with CO2 capture, transport and permanent storage as well as considering potential business models.

The results of the feasibility studies will form the basis for a decision on further progress.

The Magnum gas power plant has three combined cycle gas turbines (CCGT) with a capacity of 440 MW each. One CCGT emits approximately 1.3 million t. of CO2 per year.

The technology for producing hydrogen by converting natural gas into hydrogen and CO2 is proven and known. The new element is to design a large-scale value chain.

So far, high costs combined with lack of CO2 storage facilities have limited the development of a low-carbon value chain for hydrogen based on natural gas.

In 2016, the Norwegian government initiated a new national CO2 capture, transport and storage project. Studies confirmed the feasibility of storing CO2 on the Norwegian continental shelf, with high storage capacity and the potential to expand the facilities to manage additional CO2 volumes beyond the initial demonstration project.

If the Norwegian CCS demonstration project is realized, this may open up for future CO2 storage from other projects, including the joint Vattenfall, Gasunie and Statoil project.

Statoil has more than 20 years of experience with CO2 storage on the Norwegian continental shelf. The company has launched a climate roadmap, which details the targets for CO2 emission reductions and improved carbon intensity and energy efficiency.
