ONP’s role at NORTHSEA HYDROGEN

ONP Management leverages technical and project management know-how to execute complex infrastructure projects, including offshore-wind and hydrogen projects. We manage project teams and support clients during conceptualization, early development, FEED-phase, engineering, procurement and execution/installation up to COD. Being one of the four original shareholders of “NORTHSEA HYDROGEN® Offshore Farm” ONP is providing project -management and -coordination services for the H2-Demo-Project. The ONP-Team is liaising between the +30 involved project partners, progressing the design of the H2-plattform, setting up an extensive research program and securing the necessary funding from the BMWE.  

What is the “H2-Demonstrator Project”? Why is it important to discuss?

NORTHSEA HYDROGEN® aims to build large scale offshore wind farms in the German bight, scaled from 10-MW to  300MW to 1 GW, to produce green hydrogen on an industrial scale. Transport of compressed hydrogen to shore is achieved via vessels or pipelines.

The H2-Demonstrator Project” is designed to explore the feasibility of producing green hydrogen from offshore wind energy. The project involves the installation of a self-sufficient, autonomous jack-up platform equipped with 10MW electrolysers and auxiliary equipment to generate hydrogen directly at sea. The hydrogen-production-unit will operate next to an existing offshore wind farm (OWF) and source the required renewable energy directly from the OWF.

The primary idea behind this pilot project is to investigate and demonstrate the viability of hydrogen production using variable electricity loads from offshore wind turbines in a challenging marine environment. By harnessing the fluctuating power output from offshore wind, the project aims to prove that hydrogen can be effectively and efficiently produced even under variable and harsh conditions. This demonstrator project not only showcases the harmonization between offshore wind energy and hydrogen production but also paves the way for future large-scale offshore hydrogen projects.

Goals and expected outcomes of the Demonstrator Project - Why is it so important?

The primary goal of the Demonstrator Project is to test the feasibility of a modular design concept for an offshore hydrogen production plant. This involves creating a “proof of concept” that demonstrates effective integration of desalination, electrolysis technology and offshore wind energy. By achieving a functioning system integration under remote offshore conditions at a 10-MW-scale, the project aims to pave the way for future innovative offshore hydrogen projects. Successful demonstration will not only attract government support but also build trust and confidence among investors, by de-risking and highlighting the viability and scalability of such technologies in the renewable energy sector.

The project also aims to explore potential optimizations to enhance performance and reduce operational costs. The knowledge and experience gained from this demonstrator project will be applied to large-scale offshore hydrogen projects, already under development by NORTHSEA HYDROGEN®. This will help achieve significant cost reductions through economies of scale, ultimately making offshore hydrogen production a more viable and attractive option for large-scale energy generation.

To summarize, the goal is to take the charge, and develop, build and test hydrogen production offshore. Initially at 10 MW and then scaling up to megawatts and gigawatts level. Thereby, decoupling the advancement of this technology from political uncertainties and reducing the risk-profile for investors, insurers and operators.

We invest in team spirit and passion - ONP supports local youth football by sponsoring jerseys for the U10 team of JFV A/O/B/H/H 

The youth football club from the district of Stade, which we support, offers children from the communities of Ahlerstedt, Ottendorf, Bargstedt, Harsefeld and Heeslingen (therefore A/O/B/H/H) an ideal basis and, in addition to sporting development, also promotes strong personal development - especially through lived team spirit and targeted team building. The perfect "match" for us at ONP to live up to our social responsibility and our goal of actively shaping a future worth living.

Last Tuesday, the kids were able to prove what they are capable of in their new jerseys at a comparison tournament of SV Werder Bremen. As you can see, everyone had a lot of fun, and it makes us proud to see so many ONP logos:

We wish the whole team a lot of fun and success for the 25/26 children's football season that is now starting and look forward to many more pictures with beaming faces.

Press Release

Launch of a pioneering partnership in the floating offshore wind sector

ONP Management and Semco Maritime, both leaders in the offshore wind sector, are pleased to announce the start of their collaboration in the field of floating offshore wind. The partnership is officially sealed by a recently signed Memorandum of Understanding (MoU).

The MoU describes the planned collaboration as follows

• Both companies have a common desire to work together in the provision of services to the offshore wind industry, with a focus on the promising floating offshore wind sector.
• The MoU provides the basis for further discussions between the parties to collaborate on the joint provision of engineering and/or consultancy services.

Semco Maritime has extensive experience from the delivery of more than 20 offshore substations, as well as many years of expertise in the development of floating substations for the oil and gas and offshore wind industries and is involved in the realisation of several floating offshore wind projects worldwide.

ONP Management is an independent technical consultancy with a strong focus on the offshore wind sector, offering a wide range of services with a focus on project management and project development services.

This collaboration is an important step towards a sustainable energy future and underlines the commitment of both companies to climate protection and the global energy transition.

Knud Grimm, Managing Director at ONP Management: "As engineers, the core of our work is the utilization of our expertise to develop new, innovative technical solutions. By collaborating with Semco Maritime, ONP is taking a promising step forward in supporting our customers in developing floating offshore wind technologies and thereby contributing to the ongoing evolution of the energy transition."

Maria Jørgensen, Business Development Specialist at SEMCO Maritime: At Semco Maritime, we believe in the power of collaboration to push the boundaries of innovation. Partnering with ONP enhances our capabilities in floating offshore wind, combining our extensive experience with ONP's engineering expertise. Together, we are dedicated to providing top-tier advisory services that not only meet but exceed our clients' expectations in developing sustainable and efficient floating offshore wind solutions. This partnership is a testament to our shared commitment to accelerating the energy transition through advanced technologies.
