Activities Task 40

Task 40: Energy storage and conversion based on hydrogen

Operating Agent: Dr. Michael Hirscher

1 January 2019 – 31 December 2021; extended three years from 1 January 2022 to 31 December 2024.

Purpose and Objectives
  • Develop reversible or regenerative hydrogen storage materials (solid or liquid) fulfilling the technical targets for mobile and stationary applications.
  • Develop the fundamental and engineering understanding of hydrogen storage materials and systems that have the capacity of fulfilling Target I.
  • Develop materials and systems for energy storage and conversion based on hydrogen, including hydrogen storage for use in stationary, mobile and portable applications, electrochemical storage, and solar thermal heat storage.

Task 40 addresses energy storage and conversion based on hydrogen by developing reversible or regenerative hydrogen storage materials. In these materials, the quantitative targets for hydrogen storage capacities and operation temperatures depend strongly on the different application objectives, e.g. mobile systems, transport and distribution, or stationary storage systems. The fundamental understanding of hydrogen storage mechanisms is the key for a breakthrough in the development of materials with improved properties. For example, the effect of catalysts is not yet understood in complex or liquid hydrides, even though catalysts are important for the hydrogenation/dehydrogenation processes. For technical applications, a combined understanding of both fundamental and engineering aspects is important. The development of new materials and systems for energy storage and conversion based on hydrogen, including hydrogen, electrochemical and heat storage, will involve strong international collaborations within the Task 40.
Eight working groups are planned:
  • Porous materials (coordination polymer framework compounds, MOFs, ZIFs, COFs, and carbon-based compounds)
  • Magnesium- and intermetallic alloys-based hydrides for energy storage
  • Complex hydrides (borohydrides, alanates, amides/imides-systems, magnesium-based compounds, reactive hydride composites
  • Ammonia and reversible liquid hydrogen carriers
  • Catalysis
  • Electrochemical storage of energy (MH-batteries, ion-conduction)
  • Hydride-based thermal energy storage
  • Research and development for hydrogen storage and compression
