LOHC Technology

Ingenious Hydrogen Storage

LOHC technology offers a solution for the so-far unresolved challenge of safe and reliable storage of hydrogen. Hydrogen is not only a standard gas in industry, it is often considered to be the energy carrier of the future and in contrary to the handling of a fugacious and flammable gas, the storage of hydrogen in liquid LOHC materials is a break-through on the path towards a clean hydrogen economy.

Due to their Diesel-like nature LOHCs can be transported and distributed in the existing infrastructure for mineral-oil based fuels. They are stored in and vice versa released from the LOHC compound by catalytic hydrogenation and dehydrogenation processes.

  • Scalable storage capacity up to the GWh scale

Efficient, safe and reliable Hydrogen-Logistics

  • Centralised hydrogenation units for large-scale hydrogen-producers
  • Decentralised dehydrogenation units (containerised) for hydrogen-consumers
  • Utilisation of existing fuel infrastructure possible
  • Transport-capacity of up to 1.800 kg hydrogen per 40-ton-truck (today only ~400 kg)

Hydrogen Generation

  • Renewable hydrogen: produced from renewable energies via electrolysis – which will be integrated into the LOHC system by Hydrogenious Technologies if required
  • Industrial hydrogen: produced by steam reforming or similar

LOHC Hydrogenation

  • Chemical bonding of hydrogen molecules to the liquid carrier via a catalytic reaction @ 50 bar pressure
  • Exothermal process with 10kWh (th.) / kg H2 usable heat @ 150 °C
  • Reactor design allows for a continuous hydrogenation process

Liquid Organic Hydrogen Carrier (LOHC) – our storage medium

  • No molecular hydrogen stored
  • High storage capacity of 6.23 wt.-% equal to 630 Nm3 H2 / m3 LOHC
  • Storage medium dibenzyltoluene – liquid organic hydrocarbon
  • Liquid state in a broad temperature range between -39°C to 390°C and ambient pressure
  • Low flammability and non-explosive – even when loaded with hydrogen
  • Non-toxic and not classified as dangerous good
  • Fully reversible loading and unloading of LOHC material possible
  • No evaporation of stored hydrogen – multi-month storage possible without any losses
  • Easy storage and transport in commercially available diesel-tanks possible

Dehydrogenation

  • Release of hydrogen molecules from liquid carrier medium via catalytic reaction
  • Endothermic process with 10kWh (th.) / kg H2 @ ~300°C required for dehydrogenation
  • Hydrogen purity ensured via downstream purification
  • Fully controllable continuous hydrogen release process possible

Hydrogen utilization

  • Hydrogen as energy storage medium and re-electrification via fuel cell – which will be integrated into the LOHC system by Hydrogenious Technologies if required
  • Hydrogen as a fuel for fuel cell electric vehicles
  • Hydrogen as a chemical for industrial processes
LOHC Research

Hydrogenious’ LOHC technology is based on years of thorough research in the area of Liquid Organic Hydrogen Carriers (LOHC). As a spin-off and a company of scientists, engineers and entrepreneurs Hydrogenious Technologies commercializes LOHC technology and optimizes catalyst and reactor technology. In addition, Friedrich-Alexander-University Erlangen-Nuremberg (FAU) and the co-founding professors Wasserscheid, Arlt and Schlücker continue to push the limits of LOHC technology in their ongoing research efforts. If you are interested in the capabilities, potential and origin of our LOHC technology you can find them in the publications featured here.
