The construction industry is responsible for 23% of the world´s GHG. Regulatory restrictions and public procurement processes push for the reduction of these emissions. Electrification of construction equipment is a solution as it reduces emissions. However, charging without emission is still a challenge. One of the alternatives to this problem is to use Hydrogen or Liquid Organic Hydrogen Carriers (LOHC) as main energy source. The LOHC Hydrozine can easily facilitate this transition; however, there are still problems to be solved.
DENS’s mission is the creation of highly reliable power sources that provide renewable and zero-emission power everywhere. Based on a patented technology we develop and build reformers that provide clean and affordable hydrogen gas (H2) via the conversion of Hydrozine (or otherwise known as formic acid). With our Project DENS X4 we aim to introduce the world's first commercially available Hydrozine stationary 100 kW power generator, where our proprietary reformer transforms Hydrozine into H2 gas and subsequently supplies a fuel cell for electricity generation on demand. It is an excellent replacement of high polluting and noisy diesel generators, which emit substances like CO2, NOX, SOX, soot.
Nowadays, 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 a storage medium is necessary being the Hydrogen gas or the LOHC potential alternatives. However, hydrogen in gaseous form has the disadvantage that is not easy to store and transport in large quantities. So LOHC are more feasible; in this case Hydrozine can be used. Hydrozine is a colorless liquid that stores up to 4 times as much hydrogen compared to pressure bottles and it is safer than H2 gas which is highly flammable. The Hydrozine is produced with three ingredients: renewable energy, water and biogenic CO2 (non-fossil carbon dioxide) so this is a renewable energy storage carrier.
In the DENS reformer, the Hydrozine is converted into H2 (hydrogen) and CO2 gas. This gas mixture is then fed to a fuel cell which converts the mixture into water vapor and electrical energy. The conversion in the fuel cell takes place at low temperatures, so no harmful substances such as sulfur oxides, nitrogen oxides or particulate matter are formed. In addition, the process is completely whisper quiet. Through this cycle the original renewable Hydrozine is converted into energy emitting an equal amount of CO2 as H2O (water), making the entire use 100% renewable.
