In recent months, E-Bridge has carried out a technical and economic potential analysis for 50Hertz Transmission GmbH and investigated the possibilities of using electrolyzers for:
1️⃣ Redispatch (Benefits instead of curtailment § 13k EnWG compared to the cost-based approach)
2️⃣ Reactive power (Structure of § 12h EnWG and technical requirements)
3️⃣ Momentary reserve (Design of § 12h EnWG, technical requirements and research needs)

In a recent request to Federal Economics Minister Robert Habeck, five northern German state ministers for economics and energy have called for the development of clear framework conditions for the siting of electrolysers (Link (€): The need to locate and operate electrolysers in a way that serves the system is at the heart of the national hydrogen strategy in order to increase flexibility and limit the need for grid expansion. In addition to the choice of location, grid and electrolyser operators are therefore looking at ways to operate the plants in a way that serves the system. On the one hand, to ensure secure grid operation in the future. On the other hand, because the marketing of flexibility or participation in future markets for ancillary services can provide additional economic potential.

In the study, various converter and electrolysis stack technologies were evaluated, the current regulatory status according to TAR and EnWG was compared with the technical possibilities and economic assessments were carried out. Based on the results, the need for regulatory adjustments and recommendations for action were then derived. In order to adequately consider the perspective of future operators and manufacturers of electrolysers, interviews were conducted with a number of electrolyser operators and manufacturers.
