Opportunities for Hydrogen Storage in connection with Stochastic Distributed Generation

This paper gives an overview of the opportunities that exist for the combination of stochastic power generation and hydrogen production, storage and end-use. It is described how hydrogen storage can be applied in both isolated and grid-connected systems, and how the produced hydrogen can be utilized for stationary energy supply and as a fuel for transportation. The paper discusses the benefits and limitations of the different hydrogen storage applications, and emphasizes the need for stochastic studies both for long-term planning and operation planning. A simulation case study of using excess wind power in a weak grid to produce hydrogen for vehicles has been presented. It is shown that the penetration of wind power can be significantly increased by introducing electrolytic hydrogen production as a controllable load
