HydrogREenBoost – hydrogen for system stability
The state of Baden-Württemberg has set up a funding programme, “Future Programme Hydrogen BW”, to support the development of a sustainable hydrogen economy in the southwest. One of the measures funded is the “HydrogREenBoost” project, which is a collaboration between Karlsruhe Institute of Technology (KIT), Ulm University of Applied Sciences (THU), TransnetBW and the Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (Center for Solar Energy and Hydrogen Research Baden-Württemberg, ZSW).
The name of the project is a combination of “hydrogen”, “RE” and “green” for renewable energy, and “boost” for grid booster, meaning a battery storage system connected to the electricity grid.
Welcome to the project
HydrogREenBoost is a research project that brings together experts from science and industry for the purpose of exploring how hydrogen can be used in a way that is beneficial to the grid, with a positive effect on grid stability and grid utilisation.
Specifically, this project will continue to develop the grid booster concept, which the German Federal Network Agency (BNetzA) designated in December 2019 as a subject of research into innovative and efficient grid operation according to the Network Development Plan for Electricity (NEP). In contrast to previous grid booster projects, which have implemented intermediate energy storage by means of electric batteries, this project investigates the intermediate storage of energy in a hybrid system. This system consists of both an electric battery storage component and a hydrogen storage component, and thus could be described as a “hybrid H2 grid booster”.
While the concept is still based on an electric battery storage unit to provide the system with a fast reaction speed, a hydrogen turbine takes over from the battery after a short period of time.
The project is to be based on the grid booster concept, which uses a battery storage system to increase grid stability and maximise grid utilisation.
Experts from KIT, THU, TransnetBW and ZSW have collaborated to design a research project with three main work packages:
Work package I
Setup of a grid laboratory: The interaction of the technical subcomponents is to be tested in the laboratory and presented in a tangible way.
Work package II
Modelling of the plant and grid efficiency: The technical components will be modelled in detail to calculate electricity load flows. Different locations are to be assessed.
Work package III
Design of an implementation concept: Finally, an implementation concept is to be developed for the large-scale application of a HydrogREenBoost plant that is both beneficial to the system and economically viable.
Karlsruhe Institute of Technology
As “The Research University in the Helmholtz Association”, KIT creates and communicates knowledge for society and the environment. The institute's goal is to make significant contributions to global challenges in the fields of energy, mobility and information. To this end, around 9,600 employees work together across a broad disciplinary basis in the natural sciences, engineering, economics, humanities and social sciences. KIT prepares its 23,300 students for responsibilities in society, industry and science by providing research-oriented university studies. The innovative activities at KIT connect knowledge with practical application for the benefit of society, economic prosperity and the preservation of our natural environment. KIT is one of the German universities of excellence.
Ulm University of Applied Sciences
At the Ulm University of Applied Sciences, research and teaching is focused on current subjects and the curriculum is both practical and personal. Practical modules in the study programme, practical semesters and final thesis in cooperation with renowned companies in the region offer students an optimal combination of theory and practical application. Students thus experience how the field works in practice, can contribute their knowledge and talents, and help shape the future of technology.
As a transmission system operator based in Stuttgart, we stand for a secure and reliable electricity supply for around eleven million people in Baden-Württemberg. We are responsible for the operation, maintenance, planning and demand-driven expansion of the transmission grid of the future. Our electricity circuits are around 3,200 kilometres long and our grid covers an area of 34,600 km². This network is available to all players on the electricity market on a non-discriminatory basis and is subject to market-oriented, transparent conditions. Our modern transmission grid provides the foundation for a reliable energy supply in Baden-Württemberg, as well as a thriving economy and society.
Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg
The Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) is one of the leading institutes for applied research in the fields of photovoltaics, renewable fuels, battery technology and fuel cells as well as energy system analysis. Around 330 scientists, engineers and technicians are currently employed at the Centre’s three locations in Stuttgart, Ulm and Widderstall. In addition, there are 100 research assistants and research students. The ZSW is a member of the Innovationsallianz Baden-Württemberg (innBW), an association of 12 non-university, industry-oriented research institutes.
