Hydrogen container / PtG-Container

Hydrogen is considered the cornerstone of the energy transition and hydrogen containers or PtG containers (power-to-gas) are part of this development. Whether as enclosure for the electrolysis system or as a mobile and flexible hydrogen filling station for fuel cell vehicles: CARU Tech offers special modules for the assembly of electrolysers, controls and ancillary systems.

With support of CARU-Tech’s fully prepared power-to-gas container, hydrogen is obtained from water by electrolysis and partially downstream methanation. In this process, water is split into hydrogen and oxygen under the influence of electricity. If the resulting waste heat is also used and fed into a heating network, for example, the efficiency of the conversion of electrical energy into chemical energy in the electrolyser is around 70 to 80 percent.
The process is climate-neutral and makes an important contribution to climate protection and security of supply. The hydrogen produced in this way can be used, for example, as fuel for fuel cell vehicles or fed into existing gas networks. A plant with a capacity of up to 1 megawatt of electrical power can operate around 1,000 vehicles.

How are hydrogen containers constructed?

The plant essentially consists of the following operating units:

  • Hydrogen production
  • Water treatment plant
  • Power electronics with rectifier
  • Cooling system
  • Ancillary equipment

The PtG container is delivered as a turnkey space for converting electrical energy into hydrogen.
It is built in special CARU Tech container modules and is suitable for permanent outdoor installation. The electrolyser is housed in the container as well as the heating and cooling interfaces, the transformer and the power electronics.
