General

Excess regeneratively generated electricity from wind power plants and photovoltaic plants can be stored in the existing gas networks as chemical energy in the form of hydrogen or synthetic natural gas using the storage technology known as Power-To-Gas - just like a giant rechargeable battery. In connection with the future expansion of regenerative power generation, it is becoming increasingly important to call up excess energy when needed.

Advantages of the chemical storage of electricity in the form of hydrogen or methane (natural gas) produced from hydrogen through the use of carbon dioxide are the high energy densities, the rapid availability and the diverse direct possibilities of use for mobility, the energy industry and industry. Hydrogen, for example, is also required as an energy carrier for fuel cells, which in future will also make an important contribution to effective, decentralised energy supply and individual mobility.

IPS-FEST GmbH considers hydrogen electrolysis as a key technology. The idea is captivating: to convert excess power into hydrogen by electrolysis, to store it temporarily in the gas network and to be able to retrieve it at any time (e.g. H2 fuel cell, hydrogen filling stations or re-powering).

In this context, producing hydrogen from water by electrolysis is also the most energy-efficient way. The energy required for this is supplied by the surplus electricity generated from renewable sources when there is low demand for energy.

Principle and possible uses

Within the framework of this electrolysis process, corresponding direct current outputs are required to operate the splitting of the water. IPS-FEST produces the power supplies required for the electrolysis process according to the specifications of the respective application. IPS-FEST also supplies the corresponding power supplies in the form of DC thyristor converters and AC-IGBT inverters for the re-conversion of hydrogen into electricity if required. The stored hydrogen is converted into direct current and fed back into the three-phase supply networks via so-called DC/AC converters.

Example for a re-conversion into electricity

Mobile fuel cell 1MW as energy supplier in a container! In the container the power supply of IPS-FEST, the fuel cell/electrolysis and the required control system are already installed. The installation in a mobile container means that the fuel cell is not bound to a specific location and can be installed practically anywhere. The power supplies of IPS-FEST GmbH, which are highly valued for their high operational reliability and longevity, are proving their worth every day in tough industrial use all over the world. They are available in liquid-cooled or air-cooled design.

The power supplies of IPS-FEST GmbH are matched exactly to the individual requirement profile in close cooperation with the customer. We accompany you during the implementation of your application from the planning phase to the realisation.
