Commercially viable Floating Offshore Wind (FOW) is stimulating interest in sustainable, low-cost Green-Hydrogen (H2) production. Using energy from floating wind farms (FWFs) to generate Green-H2 offers a viable renewable energy store, balancing generation with demand, working towards achieving a Net Zero economy, diversifying available energy sources whilst decreasing the industry’s carbon footprint. Producing Green H2 offshore has inherent economic advantages, (i) no capital cost for subsea export cables and (ii) greater utilization of available wind power (load factor).
BPP-TECH has developed a complete solution design for connection of FWF to a floating Green-H2 production facility based on high TRL technologies. The novel concept is a self-sustaining, scalable system for offshore Green-H2 production. The optimization techniques developed by BPP-TECH will also reduce the CAPEX and OPEX of the overall system during its lifetime.
BPP-TECH will develop the system definition and integration tools needed for producing
Green H2 from offshore floating wind farms using existing commercially available components (TRL 8-9). The design and system integration tools needed for this are currently at TRL3-4 and need to be brought up to TRL5-6 in order to create credible system designs and performance predictions to realize the production of Green H2 from FWFs.
FWF-H2 production can drive economic growth by creating new jobs, attracting investment and reducing global emissions, moving towards Net Zero targets. There are no commercialized FWF-H2 production installations. If successful BPP-TECH’s initiative will bring significant economic benefits to the H2 supply chain, attracting investment and stimulating further innovations.
Offshore wind farms require substantial subsea export cables using High Voltage Alternating Current (HVAC). The cost of export cable lengths in excess of 100 miles significantly impacts CAPEX, possibly making some projects commercially uneconomical. An alternative solution is to produce H2 by electrolysis close to the point of electricity generation, removing the requirement for an export cable. Producing H2 offshore using FWF power offers a commercial solution to store and deliver energy onshore. This will result in diversifying available energy sources whilst decreasing the industry’s carbon footprint
Integrating H2 production with FWF is novel and lacks the essential system definition and integration tools, their absence is a serious obstacle. BPP-TECH aims to develop these essential tools by integrating existing technologies (TRL 8/9) into a Green H2 solution that will generate a high return on investment. The solution would achieve TRL 5/6. An FWF is a significant investment of time and money, and FWF developers need confidence in their return on investment which depends on identifying reliable designs with predicted performance.
BPP-TECH aims to support the Green Hydrogen growth by:
- Supporting the growth of ‘clean growth’ supply chain companies in key technology and engineering sectors.
- Providing insight into costs, performance and what is required to remove technology and market barriers to produce Green H2 using FWF.
- Supporting development of export markets for H2.
- Enabling developments in other sectors with its projects.
- Increasing number of high-qualified jobs to support Green H2 growth.
Energy Compact Description
BPP-TECH aims to collaborate with international companies to assess the techno-economic viability of producing Green Hydrogen from FWF. BPP-TECH has developed an initial technology and economic appraisal of large-scale FWF-H2 offshore production platform. The techno-economic assessment of the proposed system will define the overall performances and cost of the system integration for offshore FWF-hydrogen production incorporating state-of-the-art technology.
BPP-TECH will validate the robustness of the proposed technologies encouraging the private sector to invest alongside the public sector in the innovation journey. BPP-TECH will use case-studies to optimize the design of the proposed system. The proven success of the proposed solution will be utilized to grow confidence in outside of existing network and create a Joint Industry Project (JIP) an alliance of industrial partners involved in the production, transmission and distribution of energy, infrastructure financing and climate change services.
