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.
- 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
- 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
- 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
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.
