Hydrozine, liquid organic hydrogen carrier

Innovative new ways of generating, using and storing energy are of great importance to realize the energy transition from fossil to sustainable. For the generation of electricity, large/scale solar and wind energy are seen ways to make the energy grid more sustainable. However, there are also situations where a connection to the grid is not easy or completely impossible. In such situations it is important to store in a storage medium such as, for example, the hydrogen gas. However, hydrogen in gaseous form has the disadvantage that is not easy to store and transport in large quantities. To solve these problems, the liquid organic hydrogen carrier (LOHC) Hydrozine can be used.

Hydrozine is a colorless liquid that stores up to 4 times as much hydrogen compared to pressure botles and is also safe because it is not highly flammable. It can be produced from water and CO2 by means of electrolysis or by converting low-value biomass flows. Water and CO2 are used, as it were to transport energy from A to B.

DENS Technology

  1. Renewable energy produced must be stored so that it can be used at any other time
  2. The production of Hydrozine takes place with three ingredients: renewable energy, water and biogenic CO2 (non-fossil carbon dioxide).

Use in the DENS generator:

  1. In the DENS reformer, the Hydrozine is converted into H2 (hydrogen) and CO2 gas. This gas mixture is then fed to the fuel cell.
  2. The hydrogen from the gas mixture is converted into water vapor and electrical energy with the help of oxygen from the outside air. Because both the process and the conversion in the fuel cell take place at low temperatures, no harmful substances such as sulfur oxides, nitrogen oxides or particulate matter are formed. In addition, the process is completely whisper quiet.
  3. The renewable energy stored in the Hydrozine can now be used anytime in a variety of applications.
  4. The use of the fuel emits an equal amount of CO2 as H2O (water), making the entire use 100% renewable and 100% future-proof.

Power generation technology

DENS has developed the technology in a modular way for the supply of power. Use is made of a reformer system, a PEM fuel cell system and a battery pack. The battery pack can be used as an independent energy supply and a hydrogen source can be connected separately to the fuel cell system. In addition, it is possible to connect  solar panels or a windmill, so that the system can use other energy sources. In addition to the stationary solution in the form of a generator, work is being done on the mobile application that can be built into larger equipment such as (lifting) cranes, excavators or wheel loaders.
