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.

Step 3

> 1 GW Scale (globally applicable)

World overview of wind potentials
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

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

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”

Storage and offshore handling

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.
