‘Missing Link’ – Thermoplastic composite pipes

The offshore wind turbine manufacturer Siemens Gamesa Renewable Energy has signed a collaboration agreement with Strohm, a company specializing in the construction of thermoplastic composite pipes (TCP).

The duo said on Tuesday that they plan to develop hydrogen transfer solutions that improve the concept of decentralized green hydrogen, where green hydrogen is generated in each wind turbine generator and transported to land by an infrastructure of subsea pipelines.

In this concept, electric cables are replaced by a pipeline infrastructure, storing and transferring hydrogen. Siemens Gamesa has a technical advisory role.

Strohm designs and manufactures TCP, which the company says is particularly suitable for transporting hydrogen at sea and underwater.

Produced at its factory in the Netherlands, the corrosion-resistant technology does not fatigue and suffer from the problems associated with using steel pipes for hydrogen, such as embrittlement, according to Strohm, formerly known as name of Airborne Oil and Gas.

Manufactured in long, coiled lengths and flexible in nature, the hose can be pulled directly into the wind turbine generator, enabling offshore wind farm infrastructure to be built quickly and cost effectively, Strohm said.

According to Strohm, TCP is maintenance-free and suitable for over 30 years of operation, minimizing level cost of electricity (LCOE) and enabling the decentralized concept solution.

“As a pioneer in the wind industry and a leader in offshore wind, Siemens Gamesa has already taken important steps to shape the industry and develop the basis for a decentralized offshore solution, which fully integrates an electrolyzer into a wind turbine. offshore, with clear benefits and value – adding potential such as reduced capital expenditure, increased system efficiency and increased availability of wind farms, ”Strohm said.Credit: Siemens Gamesa Renewable Energy

‘Link missing’

Martin van Onna, Commercial Director at Strohm, said: “It’s a really exciting collaboration, working with Siemens Gamesa to understand how TCP can be the missing link in an offshore wind farm, generating green hydrogen. The key attributes of TCP – flexibility, no corrosion or maintenance requirements – enable the most cost effective infrastructure on a given wind farm. Our proven experience with offshore TCP is a prerequisite to be seen as a solution in the future green hydrogen.

Finn daugaard madsen, Innovation Manager – Power to X at Siemens Gamesa, added: “At Siemens Gamesa, we believe in the potential of green hydrogen and have been working on the decentralized concept for a few years. Strohm has accompanied us through several case studies, identifying easily usable solutions that complement our own systems. This partnership will help us innovate together in an open format, by accelerating the availability of green hydrogen.
