The role of hydrogen in high wind energy penetration electricity systems: The Irish case

摘要: The deployment of wind energy is constrained by uncontrollability, which poses operational problems on the electricity supply system at high penetration levels, lessening value wind-generated to a significant extent. This paper studies viability hydrogen production via electrolysis using power that cannot be easily accommodated system. potential benefits and its role in enabling large are assessed, within context enormous resource Ireland. exploitation this may future give rise amounts surplus electricity, could used produce hydrogen, zero-emissions fuel many experts believe will eventually replace fossil fuels transport sector. In operation powered simulated optimised. results reveal that, even allowing for cost-reductions electrolyser associated balance-of-plant equipment, low average cost market price also necessary achieve economic technology. These conditions would facilitate installation units sufficient capacity allow an appreciable increase installed simulation model was determine CO2 abatement with energy/hydrogen production.
