Regulatory Framework Regulatory conditions have to adjust to needs of Energiewende : - Grid fees - Capacity market? - Standard load profile vs flexible prices - Stroage bonus - Exemption from EEG? Already existing new conditions for new storage options like e.g. Electrolysers: - Exemption of electricity tax on application ( 9a Abs. 1 StromStG) - Exemption from grid fees (variable part) for 20a ( 118 Abs. 6 S1 EnWG) Funding of R&D- Demo-Projects through BMWi, BMU, BMVBF, EU 11 Hydrogen link between renewables and transportation Dr. Oliver Weinmann 17.10.2013
Conclusion New Energy landscape: load follows production grid extension, flexibilisation of existing PP, Smart grids & storage Storage allows for easier integration of renewables No silver bullet : but H 2 is promising for large energy quantities Electrolysis is technical viable but still room for improvements New applications for electrolyses (control power, storage, DR..) Cost ave to come down to create viable business models 12 Hydrogen link between renewables and transportation Dr. Oliver Weinmann 17.10.2013
