H2-INDUSTRIES BREAKTHROUGH: STORING HYDROGEN WITHOUT LIMITS IN LOHC

OUR INNOVATION:
LOHC IS STORABLE AT NORMAL PRESSURE & TEMPERATURE

TECHNOLOGY OF H2-INDUSTRIES

ELECTRICAL ENERGY IS STORED SAFELY UNDER AMBIENT CONDITIONS IN LOHC. EXISTING INFRASTRUCTURE CAN BE USED FOR THE TRANSPORT.

H2-INDUSTRIES TECHNOLOGY VALUE CHAIN

LOHC - THE LIQUID GOLD

LOHC binds and releases hydrogen unlimited times

LOHC can be stored in every conventional tank

LOHC does not discharge.

LOHC is less toxic than diesel.

Hydrogen can be stored under normal pressure and temperature.

LOHC ENERGY STORAGE TECHNOLOGY

The H2-Industries energy storage solution is based on two separate processes namely the loading (hydrogenation) and unloading (dehydrogenation) of a liquid energy carrier. This liquid is an organic molecule showing similar physic-chemical properties as diesel. A big advantage of the hydrogen being chemically bonded to the liquid carrier is that it can be stored under ambient conditions (p=1bar, normal temperature) without suffering any self-discharge or the loss of hydrogen. One liter of the energy carrier can store an equivalent of 2 kWh thermal energy or, after reconversion, 1 kWh electrical energy.

LOHC STORAGE

The storage process itself is a chemical reaction under elevated temperatures (T=150 - 180°C) and pressure (p=30 bar). An electrolyzer produces hydrogen at this pressure level in the STORE eUNIT, so no additional energy consuming compression is necessary. The hydrogen is fed into a hydrogenation unit filled with the porous catalyst forming a catalyst bed. The energy carrier is subsequently rinsed over the catalyst bed at 30 bars and the reaction of hydrogen and the LOHC occurs at the active precious metal sites of the porous catalyst. The chemical binding of H2 to the molecules of the energy carrier takes place on the catalyst. This reaction is an exothermic (i.e. energy is produced) reaction, allowing to use this waste heat for other applications. The loaded energy carrier (LOHC+) will be pumped to the storage tank.

LOHC RELEASE

The release process takes place in our RELEASE eUNITS, where the hydrogen is released at elevated temperatures (T=270-300°C) and pressure (p=2-5 bar). This reaction is endothermic (i.e. the process consumes energy). The energy required for the dehydrogenation can be provided by burning a part of the originating hydrogen itself. The loaded LOHC+ is fed into the RELEASE eCELL and at the active sites of a precious metal catalyst the dehydrogenation takes place. The resulting hydrogen is reconverted into electrical energy in a fuel cell. The unloaded liquid energy carrier (LOHC-) will be pumped to a tank to be loaded again; in the storage process when there is excess energy available.

STORE eRACK & RELEASE eRACK

Our 66 kW eRACKS are the basic components for all our products.

The electrical efficiency is 25% (power to power). The by-product is useable heat.

Based on the 66 kW eRACK, we offer our eBLOCK container solutions from 66 kW up to 1.65 MW electrical power.

The store eRACK converts electrical power via electrolysis to hydrogen and stores hydrogen into LOHC.
The release eRACK sets the hydrogen free, which is then burned in the fuel cell in the unit.
The basic eRACK is a standard 19-inch rack 1100*600*2000 mm (D*W*H) that can be scaled to containers or hall size storage (up to GW buildings).
Each eRACK is monitored remotely and almost mainenance-free.
