Key insights from the project include:
- Offshore production of hydrogen from offshore wind and shipping of compressed gaseous hydrogen is technically doable.
- PEM electrolysis is the preferred technology for the offshore environment due to space limitations and dynamic operation behaviour.
- The project approach and logistics concept based on transporting hydrogen in compressed gaseous form, while generally overlooked, is unique.
- A compression-based hydrogen supply chain seems preferable in combination with intermittent hydrogen production from renewable electricity, like (onshore) wind and solar (in an island mode setting).
With the project coordinator PNE AG, the Fraunhofer Institute for Solar Energy Systems ISE, SILICA Verfahrenstechnik GmbH, KONGSTEIN and Wystrach GmbH, the project “OffsH2ore” brings together an experienced and complementary consortium of industry partners and academia from across the value chain.
KONGSTEIN, with its unique experience in logistics concept planning and transport & installation activities in complex offshore operations, will be responsible for the development of a hydrogen offshore logistics concept, including hydrogen loading arrangements, vessel design and transport concept from offshore site to shore.
KONGSTEIN enables the green shift in the energy industry by supporting clients striving towards a sustainable use of resources. It provides technical advisory and project management to deliver innovative, efficient solutions to the offshore renewables and maritime industries.
KONGSTEIN combines its expertise in these industries with providing state of the art services in green hydrogen. The common thread throughout our markets and clients is our clear commitment to clean energy at sea, facilitated by our network of Norwegian and German engineers and mariners.

About Fraunhofer Institute for Solar Energy Systems ISE
With a staff of close to 1300, the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg, Germany is the largest solar energy research institute in Europe. Fraunhofer ISE is committed to promoting sustainable, economic, safe and socially just energy supply systems based on renewable energies. Its research provides the technological foundations for supplying energy efficiently and on an environmentally sound basis in industrialized, threshold and developing countries throughout the world. Focusing on energy efficiency, energy conversion, energy distribution and energy storage, the Institute develops materials, components, systems and processes in five business areas. One particular feature of Fraunhofer ISE is its excellent technical infrastructure, which is organized into eight laboratory centers and four technology evaluation centers providing testing and experimental services on a production scale. In addition, the Institute has several accredited testing facilities. The Institute is a member of the Fraunhofer-Gesellschaft, Europe’s largest application-oriented research organization.
About SILICA Verfahrenstechnik GmbH
For more than 90 years, Silica Verfahrenstechnik GmbH has been designing and manufacturing process plants for the purification, drying and liquefaction of gases at its site in Berlin. The topic of hydrogen compression and purification has occupied the company since the delivery of the first hydrogen plant in 1941. Since that time, we built a vast number of Hydrogen units and Silica plants became a part of technological development in this field. Besides of the high quality level and reliability of the plants Silica contributes decades of experiences in the integration of process packages into a complex overall system in compliance with current engineering standards and regulations. More recently, Silica has been involved in engineering and manufacturing of various projects for the production and further processing of “green” hydrogen.
