Fusion energy developer Proxima Fusion has announced an extension to its Series A round with €15m ($17.6m) in additional funding as it seeks to develop a “sovereign” fusion power plant for Europe.

The company said the additional funding came from CDP Venture Capital, an entity backed by the Italian state, the European Innovation Council Fund (EICF) and Brevan Howard Macro Venture Fund.

The €15m Series A extension brings the company’s total funding to €200m and shows investors’ understanding that Europe needs to build its own sovereign fusion company, a statement by the Munich-based company said.
