50Hertz and TenneT awarded for PtG projects

26.07.2019

Last week, Peter Altmaier, the German Federal Minister for Economic Affairs and Energy, announced the winners of the ideas competition “Reallabore der Energiewende” (“Real Laboratories of the Energy Transition), which aims to promote promising energy technologies of the future, especially in the field of hydrogen technology. The winners include the two TSCNET shareholders 50Hertz, the transmission system operator (TSO) from north-east Germany, and Tennet, the Dutch-German TSO, as they are both involved in award winning projects.

Tennet is cooperating with Gasunie and Thyssengas for ELEMENT ONE, a power-to-gas (PtG) plant to be built in the German federal state of Lower Saxony, which will be capable of converting up to 100MW of electrical power into gas. ELEMENT ONE is in the planning phase, but the project partners are confident that the results of the project will provide crucial information on electricity and gas grid integration, the development of operator models and the regulatory environment. With their approach, they aim to accelerate the urgently needed transfer of technology and innovation from research to practice in the field of sector coupling and hydrogen technology.

Key technologies of energy supply
50Hertz is involved as associated partner in two winning PtG projects: “GreenHydroChem Mitteldeutsches Chemiedreieck“ in Saxony-Anhalt, and “Reflau – Referenzkraftwerk Lausitz“ in Brandenburg. These two projects also focus on sector coupling and hydrogen technology. The partners for GreenHydroChem are Siemens, Linde, and the Fraunhofer Institute for Microstructure of Materials and Systems (IMWS). With a 50MW electrolyser, regeneratively generated electricity is first to be converted into hydrogen and oxygen. The hydrogen is then converted in refineries into base chemicals and methanol, which can be blended with conventional fuels for the use in the transport sector. With Reflau, the partners want to combine and test in practice key technologies of energy supply with renewable energies and hydrogen as a chemical storage.

Dr. Dirk Biermann, Chief Markets & System Operations Officer at 50Hertz, welcomes the support for innovative technologies: “With our involvement in the laboratories, we are specifically promoting the development of Power-to-X technologies for the energy market. Because if things get serious in a few years’ time, we will need proven and grid-compatible experience with this new technology.”
