Industry standard for cost-effective hydrogen production

General – Hydrogen Production

H2sea, Bosch Thin Metal Technologies and TNO are proud to report the completion of the IPOSH (Innovative Process Design for Offshore Hydrogen) project.

This pioneering study aimed to optimise the design of offshore hydrogen production systems, reducing the Levelised Cost of Hydrogen (LCOH) by 10-20%, and achieved this goal.

The project was made possible through the support of the Dutch TKI Offshore Energy Program.

Traditionally, electrolyser stacks are designed first, with the balance of stack (BoS) and balance of plant (BoP) components selected afterward to accommodate the stacks.

However, the IPOSH project is one of the first in the world to consider all components equally important from the outset. This integrated approach ensured that cost savings were realized through simultaneous optimization rather than retrofitting elements to pre-designed stacks. By designing the overall system, the project aimed to achieve a higher level of efficiency and cost-effectiveness.

The IPOSH project has adopted a lifecycle-based methodology, evaluating critical aspects such as plant design, transport, installation, maintenance, operation, and decommissioning. The project assessed stack replacement rates under different operational scenarios and module sizes through a model-based analysis to enhance efficiency and longevity.

A key focus of the project was to establish general requirements for offshore electrolysis, addressing factors such as system footprint, maintenance needs, and environmental impact. By implementing a system engineering approach, the partners ensured that the electrolyser system was holistically optimised rather than constrained by existing design limitations. This will enable the identification of the most cost-effective and scalable configurations for future offshore hydrogen production.
