Offshore hydrogen production using wave energy

Abstract

The aim of this thesis is to present and evaluate a proposal for designing an off-grid offshore electrolysis plant powered by wave energy. This plant includes PEM electrolyzers, a Reverse Osmosis system to produce water with adequate conductivity, a compression unit to store the hydrogen for transport, and batteries for temporary storage of electricity for short-time balances. Firstly, a description of the H2OCEAN Project is given. Then, an introduction with previous works and a presentation of the two proposals that will be depicted is presented. After that, the components that comprise the proposed plants are justified and described and simple mathematical models of the different sections of the plant will be calculated. Finally the performance of the plant in a specific location is tested in detailed by using measured data, studying the influence of sizing on the expected performance in the two different proposals.
