LOHC technology turns hydrogen into a secure power storage technology

H2-Industries solutions render the use of hydrogen gas in power storage technology simple, safe and effective making it possible to store, transport and release large quantities of electricity in an environmentally friendly, harmless way.

Energy storage in comparison

Hydrogen is an ideal energy source. It is easy to produce using renewable energy sources and is available in large quantities. No pollutants result from H2-Industries’s processes. Nothing is burned. Nothing is polluted. Nothing is damaged.

 

H2-Industries technology is revolutionary and portends a huge advance in the electricity market.it Hydrogen has become a safe energy source from creation, storage, and transport to release.

The LOHC technology is based on liquid carriers, that bind hydrogen chemically.  Within H2’s process, stored hydrogen is not volatile and cannot self-discharge. The LOHC can be charged and discharged only in combination with a catalyst, infusing and releasing hydrogen, as often as needed making it remarkably cost effective

Hydrogenation of the LOHC

H2-Industries storage solutions work by charging (hydrogenation) and discharging (dehydrogenation) the LOHC. The charging and discharging are independent processes using proprietary catalyst technology

The chemical process for storing hydrogen in the LOHC is performed under pressure. This allows an electrolyser to deliver the hydrogen directly, rendering additional energy-intensive compression unnecessary. The chemical reaction in which the hydrogen is bound in the LOHC takes place in a hydrogenation unit with a bed of porous noble metal catalysts and metered LOHC. This exothermic reaction heat releases heat, which is further utilised in downstream processes. Finally, the hydrogen-charged LOHC+ (perhydro-dibenzyltoluene) is pumped into the storage tank.

Dehydrogenation of the LOHC

The hydrogen in the charged LOHC+ is recovered at a temperature of 250 to 300 degrees Celsius. This endothermic reaction requires heat, which is provided within the reaction process. The release process takes place in a dehydrogenation unit with a catalyst. Here, the chemical bond between the energy source and the hydrogen is once again released. The hydrogen is removed from the reactor as a gas and converted directly into electricity in a fuel cell. The discharged LOHC- (dibenzyltoluene) is stored in a tank until it is needed again. The LOHC cycle is closed.
One litre of LOHC stores one kilowatt hour of electricity and one kilowatt hour of thermal energy in the form of hydrogen. Reconversion via a fuel cell makes the electrical energy available. LOHC technology are is safe and environmentally friendly, with unlimited storage capacity, and it is rechargeable and stable for long periods of time. It is compatible with existing infrastructure and its price is unrivalled.
In combination with wind or solar energy systems, LOHC technology from H2-Industries can help facilitate the energy transition from fossil fuels to renewable energy, making sure it is safe. Specifically, it makes renewable energy baseload capable, which means it provides enough power to the grid so that grid energy stays stable and continuous).
