Hydrogen production

  • Electrolyser technologies
    reforming (e.g. steam reforming), biochemical production (bacteria and green algae – waste water systems), hydrogen generation by means of concentrated solar radiation (high-temperature electrolysis), hydrogen as a by-product, operating modes of hydrogen generation systems (e.g. fluctuating operation of electrolysers according to renewable energy supply)
  • Hydrogen usage paths
    Fuel cells (stationary, mobile, portable), H2 combustion (engines and gas turbines), process engineering (H2 as a chemical raw material)
  • Hydrogen infrastructure
    Transport network, distribution network, filling facilities (e.g. H2 filling station), storage
  • Stack technologies (properties and current state of development)
    Alkaline fuel cells (AFC), alkaline polymer fuel cells (AEMFC), phosphoric acid fuel cells (PAFC), polymer electrolyte fuel cells (PEMFC, HT and NT), molten carbonate fuel cells (MCFC), solid oxide fuel cells (SOFC), bidirectional systems (electrolyzer / fuel cell ), microbial fuel cell
  • Fuels
    Hydrogen, gaseous and liquid hydrocarbons, others
  • Auxiliary units and peripherals
    Gas treatment, water treatment, power electronics, control and regulation, communication technology, heat extraction
  • Stationary
    Emergency power supply, use in single-family homes and apartment buildings for self-supply with electricity and heat, use in trade and industry (electricity and process heat), operating modes for fuel cell CHP (heat demand-oriented, electricity demand-oriented, grid-related (control power), grid-connected and off-grid).
  • Mobile
    Cars, commercial vehicles, industrial trucks, rail vehicles, ships, aerospace, portable (e.g. camping, charging systems)
  • Expansion of renewable generation (development tendencies in the distribution grids)
  • Development of energy requirements (electricity, heat, gas)
  • Network requirements
  • Network connection of decentralized producers
  • Electrotechnical properties of the systems
  • Operation of virtual power plants, microgrids and cellular networks
  • Interaction of different energy sources (sector coupling: electricity, heat, gas)
  • Interaction of different applications (mobile and stationary)
  • Development of costs for electrolysers and fuel cells
  • Market development
  • Economic (energy policy) framework (e.g. tariff structures)

  • Certification of “green” hydrogen
  • Funding programs

“Electrochemical energy storage and converters” have always been part of the subject area of ​​department 1 “Central and decentralized generation of electrical energy”. Up to the year 2000 there was the then technical committee FA 1.5, incidentally the only technical committee besides nine departments. The ETG took into account the increasing research in the field of fuel cells by giving itself a new name in 2000 under Prof. Hartkopf, then TU Darmstadt: Technical Committee 1.5 “Fuel Cells” (today V1.1). Since then, the development of stationary and mobile fuel cells has been thematically accompanied. In addition to the development of the fuel cell, other future-oriented CHP technologies are of course also included in the considerations.

Even at the first meeting, the grid integration of stationary fuel cells emerged as a subject of controversial and lively discussions. The question arose as to how the large numbers of units aimed at by fuel cell manufacturers in private households could be integrated into the distribution network without any noteworthy effects. These questions were clarified by an ad hoc working group, which since 2002 has been called the Technical Committee V1.2 “Grid Connection and Decentralized Structures”.

In practice, the technical committees V1.1 and V1.2 almost always met together and carried out most of the work together. In the course of a merger, it made sense to work more closely with the VDI Technical Committee on Hydrogen. This cooperation later became today’s VDI-VDE joint technical committee for hydrogen and fuel cells.
