December 23, 2025 | A couple of big funding rounds for silicon technologies this month, as well as technologies for grid monitoring, residential applications, data center power, and an Indian EV player.
$80M: Series D for Silicon Solid-State Batteries
Blue Current announced a more than $80 million Series D extension funding round anchored by Amazon.com, with participation from Koch Disruptive Technologies, Piedmont Capital, Rusheen Capital Partners, and Allen & Company. The fundraise accelerates the commercialization phase of Blue Current’s silicon composite battery platform, delivering best-in-class safety and performance for the mobility and stationary storage sectors. In connection with the fundraise, James Hamilton, Amazon Senior Vice President and Distinguished Engineer, is joining Blue Current’s Board of Directors. Blue Current’s solid-state battery platform has been designed from first principles to deliver on the promise of next generation solid-state batteries – improved energy density and charge rates, inherent safety and thermal stability, and the ability to operate at low pressures. The Blue Current platform employs earth-abundant silicon and elastic polymer anodes paired with fully dry electrolytes across multiple formulations optimized for mobility applications and stationary energy storage systems. The result is a cost-effective, highly scalable solution that can be manufactured at scale using today’s established lithium-ion battery equipment.
$55M: Series B for Continuous Grid Monitoring Technology
Gridware announced a $55 million Series B strategic growth round led by Tiger Global and Generation Investment Management to accelerate deployment of its continuous grid monitoring technology globally. The round also continues support from existing investors Sequoia Capital, Convective Capital, Fifty Years, True Ventures, Lowercarbon, and Y Combinator. Gridware’s pole‑mounted Gridscope system enables Active Grid Response (AGR) by measuring mechanical, electrical, and environmental signals and enabling real-time understanding of grid conditions—identifying hazards as they emerge. By pinpointing the location and identifying the cause of outages, AGR positions line crews to respond quickly and safely, and before disaster occurs. Gridware’s solution empowers utilities to restore power faster, and in some cases prevent failures all together, ultimately strengthening the resilience of our grid.
$40.3M: Series A for Production of SiC
Zadient Technologies raises Eur 35 million in a Series A equity funding to accelerate the production of silicon carbide (SiC) semiconductors in Europe. The fund “Révolution Environnementale et Solidaire”, funded by Crédit Mutuel Alliance Fédérale’s societal dividend and managed by Crédit Mutuel Impact, led this round alongside European Innovation Council Fund. Zadient’s historical shareholders also took part in this round. Zadient Technologies is a French company developing an innovative process for the production of SiC that delivers both very low production costs and unprecedented very high purity. It operates at the beginning of the SiC semiconductor value chain, producing the source material from which SiC wafers and chips are fabricated. It also addresses yield improvements in large diameter wafer production which is presently a main constraint in the industry.
$30M: Series F for Batteries for AI Data Centers
ZincFive, the world leader in nickel-zinc (NiZn) battery-based solutions for immediate power applications, has successfully closed an oversubscribed $30 million Series F funding round. With this funding, the company has raised $254 million since its founding in 2016 and is positioned to rapidly scale its commercial footprint and manufacturing capacity to meet accelerating demand for AI data center power solutions. Since inception, ZincFive has been backed by a strong consortium of climate and industrial investors, including Helios Climate Ventures, Climate Investment (CI), Japan Energy Fund, General Ventures, and Clear Creek Investments, among others. With nearly 2 GW of nickel-zinc battery backup cabinets deployed or contracted across the global data center industry, ZincFive is rapidly scaling production to execute on its growing commercial pipeline for safe, sustainable, and high-performance power solutions for mission-critical applications.
$21M: Series A for Integrated Energy Solutions
Enshift focuses on sustainable energy solutions for investment properties from a single source. Following strong growth in 2025 and projects worth CHF 60 million, the company intends to drive forward its expansion in Europe. To this end, the Zug-based company has secured an investment of CHF 16 million and entered a partnership with UBS, “which will support Enshift’s green investments in the future and enable further expansion of the business in Europe,” according to a press release.
$3.5M: Series B for Industrial Heat
247Solar, the MIT-born innovator of clean, always-on industrial heat plus electricity for commercial and industrial customers, has secured $3.5 million from existing investors, with additional commitments under active due diligence. The new funding will help the company advance its $250M active pipeline on six continents that includes a Top-20 global utility, off-grid mining operations, and other applications.
$3.5M: Series B for Indian Battery Manufacturing
India’s EV battery startup Neuron Energy has secured ₹31 crore in a Pre-Series B funding round. The funds, led by Equanimity Ventures along with investments from the Rajiv Dadlani Group, Thackersay Family Office, Chona Family Office and other high-net-worth investors, will enable Neuron to boost its manufacturing capacity to 3 GWh annually. The plan includes building a fully automated, state-of-the-art battery facility for electric four-wheelers and buses at Chakan, Pune — signaling the company’s ambitions beyond two-wheelers. Beyond scaling production, the capital infusion will fuel R&D, support expansion into heavier EV segments, and help Neuron Eye a global footprint. According to Neuron, the low-CapEx and low-OpEx model it follows has helped it maintain profitability year-on-year; with this round, total funding now reaches ₹80 crore.
