Sodium-ion funding, Polish storage acquisition, and California fuels purchase
Peak Energy closed a $108 million Series B led by General Motors Ventures to scale sodium-ion battery production and data-center energy infrastructure, with a 4 GWh Sacramento plant slated for the first quarter of 2027. Tauron bought a 28.27 MW/120 MWh battery project in Lower Silesia, set for commercial operation in February 2027 and backed by a capacity contract through 2045. XCF Global agreed to acquire a roughly 50 million-gallon annual renewable fuels plant in Paramount, California, producing sustainable aviation fuel and renewable diesel.
Peak Energy’s oversubscribed round drew backing from General Motors Ventures and several technology investors. The company reports more than $1 billion in customer commitments and plans for its Sacramento plant to begin output in the first quarter of 2027; passive cooling is intended to simplify systems and reduce upkeep.
Tauron’s purchase covers a construction-ready project with 40 containers linked to its grid, plus a capacity-market contract spanning 2029–2045. XCF’s Paramount site would make sustainable aviation fuel, renewable diesel and naphtha; restart is expected to take nine to twelve months and cost about $30 million.
The battery investments could affect local manufacturing workers, grid operators and data-centre users by adding storage capacity and domestic supply. Tauron’s project may support network reliability and long-term energy contracting in Lower Silesia. XCF’s restart could affect plant employees and regional fuel markets by increasing renewable fuel output, while broader benefits depend on construction, permitting and operational timelines.
