Innovative Design for Offshore Hydrogen Production Cost Reduction
Key Ideas
- H2SEA, Bosch Thin Metal Technologies, and TNO collaborated on the IPOSH project to optimize offshore hydrogen production systems, reducing costs by 10-20%.
- The project adopted an integrated approach that simultaneously optimized all components of the system, achieving higher efficiency and cost-effectiveness.
- Findings from the study will guide future offshore hydrogen developments, strengthening the role of hydrogen in a sustainable, low-carbon energy system.
- Additionally, H2SEA is studying monopile-based structures for offshore hydrogen wind turbines, aiming to reduce energy storage system costs by 75%.
Dutch green hydrogen company H2SEA, in partnership with Bosch Thin Metal Technologies and TNO, completed the IPOSH project to holistically optimize the design of offshore hydrogen production systems. This collaboration successfully reduced the levelized cost of hydrogen by 10-20%, focusing on a new approach that considered all system components equally important from the beginning. By integrating design elements like electrolyser stacks, balance of stack (BoS), and balance of plant (BoP) components, the project aimed to enhance efficiency and cost-effectiveness. Through a model-based analysis, various operational scenarios and module sizes were evaluated to improve system longevity and efficiency. The study highlighted the potential to design cost-effective and scalable configurations for future offshore hydrogen production, free from existing design limitations. The findings of the project are expected to provide valuable insights for upcoming developments, contributing to the advancement of offshore hydrogen as a key player in sustainable energy systems.
