The Open DC Alliance is a leading consortium dedicated to promoting and standardising DC technologies. As a member of the Alliance, DEHN can contribute to the development and implementation of future-oriented DC solutions that improve the efficiency and environmental impact of the energy supply. DC technologies offer significant environmental benefits. They reduce energy losses and increase energy efficiency which, in turn, reduces CO₂ emissions and allows a more sustainable use of resources.
Renewable energies, like photovoltaic systems, and storage systems, such as fuel cells, can be integrated much more efficiently into a DC grid. That is why direct current is an essential component for the success of the energy transition. The two DC INDUSTRIE research projects reveal that energy consumption in existing systems can be reduced by up to ten per cent. Another benefit is the reduced need for copper in conductors. While conductors with four to five wires are required for alternating voltage, one to two wires less are needed for direct voltage. This represents a copper saving of more than 40 per cent.
For many years, DEHN has been committed to protecting DC systems and offers customised protection solutions. The company has a DC test field where surges and DC networks can be simulated. The specific source characteristics of PV systems can also be reproduced there.
The company was particularly active in the forerunner project DC-INDUSTRIE and was able to gain valuable insights and experience.
These are channelled into pilot projects dealing with DC grids in industrial applications and buildings. DEHN supplies, for example, DC surge arresters for local public transport systems and special surge protection solutions for photovoltaic systems.
