en.Wedoany.com Reported - The EU-funded DC Power project is developing a medium-voltage direct current (DC) grid with an operating voltage of 3 kilovolts (3kV), aimed at connecting renewable energy sources, batteries, and high-power industrial applications to enhance energy efficiency and reduce system complexity. The project is coordinated by Jens Merten from the French Alternative Energies and Atomic Energy Commission (CEA).

Direct current (DC) power technology is already common in everyday devices such as smartphones and laptops, but the DC Power project is expanding its application to larger scales. This medium-voltage DC grid can integrate renewable energy sources and energy storage devices more efficiently than traditional alternating current (AC) systems, while also serving high-power industrial scenarios.

The technology is planned to be demonstrated at two real-scale industrial sites in Greece: a data center and an electrolysis facility. By reducing unnecessary power conversion steps between AC and DC, the project consortium aims to improve energy efficiency and reduce material usage and system complexity.

In addition to efficiency gains, the DC Power project is also addressing challenges such as grid stability, interoperability, and the development of new medium-voltage DC standards. These efforts are crucial for advancing the decarbonization of Europe's energy-intensive industries and meeting the rapidly growing power demands of sectors like data centers and electric vehicles. In discussions, Jens Merten noted that medium-voltage DC grids are still a relatively new concept but have the potential to become a key component of Europe's industrial energy system in the future.
