Design of green hydrogen production from offshore wind enegy

Abstract

Establishing hydrogen production infrastructure from renewable energy is a high priority for the energy transition. This project analyses options for deployment using offshore wind generation to power electrolysis for green hydrogen production. A case example of northern Spain is used to examine the optimisation and sensitivity of trade-offs between generator and electrolysis locations, as well as electricity and hydrogen transport. Both, onshore and offshore electrolyser locations are analysed.

Using this case example enables demonstration of the logical sequence of infrastructure development priorities; an assessment of the critical locations for renewable energy; and most importantly an improved understanding of the sensitivity of different assumptions used to complete the whole system analysis. To this end, a sensitivity analysis is carried out using @RISK software to define the reliability of the results obtained, as well as the key factors that dominate the decision-making in the system design.

The study concludes by presenting a decision-making tool to determine the optimum location of both the wind farm and the electrolyser, as well as the transport method for the case site to achieve the established requirements and an assessment of resilience for the outline system design.
