This paper gives an overview of the opportunities that exist for combining wind power and hydrogen (H2) production in weak grids. It is described how H-2 storage can be applied in both isolated and grid-connected systems, and how the produced H-2 can be utilized for stationary energy supply and/or as a fuel for transportation. The paper discusses the benefits and limitations of the different H-2 storage applications, and presents a logistic simulation model for performance evaluation of wind-H-2 plants. A case study simulating the use of excess wind power in a weak distribution grid to produce H-2 for vehicles has been presented. It is shown that the penetration of wind power can be significantly increased by introducing electrolytic H-2 production as a controllable load. The results also indicate that there are large benefits of using the grid as backup for H-2 production in periods with low wind speed, regarding the H-2 storage sizing and the electrolyser operating conditions.
