The project pipeline

Step 1

10 MW Demonstrator (OWF Alpha Ventus DE)

Overview of offshore wind projects at German northsea

Desalination and electrolysis are carried out on a H2-production platform, mounted on top of a bottom-fixed foundation. All components are tested for production, storage, and re-electrification. Input data is provided for research projects, aiming to achieve proof of concept by 2028.

Step 2

300 MW Pre-Commercial Project (European OWF area)

Overview of offshore wind projects in Europe

The project involves a 300 MW production platform. H2-transport will be facilitated either via pipeline or ship. The technical concept will be developed further under a funding regime.

10 MW Demonstrator: Alpha Ventus

We are developing a demonstration project to validate the feasibility of hydrogen production under challenging offshore conditions. With an installed electrolysis capacity of 2×5 MW, the project is integrated into Alpha Ventus, Germany’s first offshore wind farm. It leverages the existing foundation and operational setup to minimize additional infrastructure requirements. The initiative also features a self-sufficient research platform designed to test all critical technical components, including desalination, electrolysis, hydrogen storage, and re-electrification processes.

MoU to jointly develop the NSH-Demo-Project was signed on  20th November 2024 between:

What we want to achieve:

A proof of concept for offshore electrolysis
Performance data of Electrolysis process coupled with fluctuating renewable energy
Compatibility assessment of auxiliary equipment such as compressor and desalination plant with electrolysers under fluctuating electricity and offshore environment
Investigation of hydrogen intermediate storage, re-electrification for emergency power supply and possibly refueling of hydrogen powered offshore vessels with the produced hydrogen
Visibility for all involved partners (research institutions, regulatory bodies, industry, finance, insurance)

Our 300/1000 MW Platform concept

Harnessing the immense wind resources far out at sea, the project focuses on creating a production facility operating in „island mode“ without the need for a grid connection. An offshore platform serves as the core of the system, housing all necessary electrical and technical equipment, a control center, as well as facilities for desalination, electrolysis, and hydrogen storage. Thanks to its modular design, the system is highly scalable, with each module offering a capacity of 300 MW. The produced hydrogen is transported either by ship or pipeline, ensuring flexibility and efficiency in delivery.

What we want to achieve:

Production of up to 70,000t of green hydrogen per year at an industrialized level
Highest level of redundancy and security against foreign influence
Green Hydrogen “Made Localy”

The H2 Production flow

Storage and offshore handling

Small buffer tanks on the topside ensure re-electrification capabilities, while an underwater hydrogen storage system exceeding 500 MWh per unit is under development.

A Double Anchor Loading (DAL) system enables the efficient offloading of hydrogen to shuttle tankers. Additionally, the platform includes an offshore refueling station for hydrogen-powered Service Operation Vessels (SOVs) and Crew Transfer Vessels (CTVs), supporting sustainable maritime operations.
