Abstract
Green hydrogen (hydrogen from renewable energy), produced through water electrolysis, has emerged as a crucial solution to achieving the objective of net zero emissions by 2050. Understanding the diverse technologies involved becomes paramount as interest in green hydrogen production grows, particularly for large-scale integration into renewable energy power plants and various industrial and transportation sectors. In this regard, this paper proposes a novel ‘wave-to-hydrogen’ system for green hydrogen production. The system uses wave energy with hydraulic power take-off to produce hydrogen, which has several benefits over other renewable sources such as wind and solar. The proposed system offers two crucial elements for hydrogen production from water electrolysis: pressurised water for reverse osmosis and electricity for electrolysis. As a result, it eliminates the need for parasitic electrical energy to pump water for reverse osmosis, required for other renewable energy technologies. The proposed system is tested in the Matlab/Simulink environment, under various wave conditions, to illustrate the effectiveness of the proposed approach.
