| DG Matrix | DG Matrix innovative solutions unlock gigaton-scale emissions reductions by enabling electrification anywhere and everywhere with less material and a smaller footprint. | $60M | Series A | Feb 18, 2026 |  |
| ZincFive | ZincFive is an intelligent energy storage and delivery solutions company providing nickel-zinc battery based UPS solutions for mission-critical applications in data centers, intelligent transportation, motive power, and other industries. With 74 patents awarded and 29 patents pending, ZincFive leverages nickel-zinc chemistry within our solutions toprovide high power density and performance simultaneous with superior safety and environmental advantages. ZincFive was founded in 2016 and is based in Tualatin, Oregon. | $30M | Series F | Dec 04, 2025 |  |
| GDI | GDI develops and manufactures silicon anodes for Li-ion batteries. The company was founded in 2009 and is based in Rochester, New York. | $11.5M | Series A | May 19, 2025 |  |
| Coreshell Technologies | Coreshell Technologies is accelerating the world’s transition to electric transportation and renewable energy by solving the key degradation issue in rechargeable batteries. Their breakthrough nanolayer thin-film coating technology protects batteries from degrading chemical reactions and is uniquely capable of seamlessly fitting into existingmanufacturing while producing the step change needed in the capacity, safety, and cost of batteries. |  |  | Mar 18, 2025 |  |

| Aqua Membranes | Aqua Membranes is revolutionizing RO membrane filtration with its unique printed spacer technology. The Polymer is applied directly to the flat sheet membrane to create a customized raised pattern that replaces conventional extruded mesh feed spacers. Unlike traditional membrane spacers that trap particles and biofilm within the spacer mesh andthereby obstruct flow, the printed dimensional spacers optimize flow patterns and turbulence throughout the membrane element, minimizing the entrapment of particulates and organic fouling. Printed spacer technology also increases permeate flow, improves flux and recovery, minimizes system pressure drop, and extends the operational life of a membrane element.Aqua Membranes' unique technology is perfect for spiral-wound membrane manufacturers eager to improve their product performance and whose customers demand more durable, low maintenance elements that can withstand challenging feed streams. Its technology provides a more open design and reduces fouling. Their technology offers a significant reduction in both Capital and Operating Expense in membrane plant operations. | $4.2M | Series B | Oct 07, 2024 |  |
| Maxterial | Maxterial modifies the surface shape or texture of versatile materials, through a method that is very affordable and easy to introduce into the existing manufacturing process. The resulting microtextured materials dramatically reduce the contact area for the objects and droplets that contact the material surface. | $8M | Series A | Jun 20, 2024 |  |
| Alsym Energy | Alsym™ Energy has developed an innovative low-cost, high-performance rechargeable energy storage technology that’s free of lithium and cobalt, and ideal for applications such as stationary storage, maritime shipping, and electric vehicles.By using readily available, inherently non-toxic and non-flammable energy storage materials, Alsym is workingto deliver wide-duration storage with performance comparable to lithium ion at a much lower cost, speeding the pace of decarbonization for people around the world. | $78M | Series C | Feb 22, 2024 |  |
| Ambient Photonics | The proliferation of connected devices promises to revolutionize consumer, commercial and industrial applications with greater convenience, lower operational costs and data-driven performance improvements. Already consumers have fallen in love with smart home conveniences, while many businesses have begun to reap the benefits of connected devicedriven efficiency gains such as electronic shelf labels and occupancy sensors. Giga scale applications for these technologies are around the corner: the potential exists for billions of wireless sensors to be installed during the coming decade, with nearly half located inside buildings. However, the challenge of reliably and affordably powering these devices has continued to limit IoT viability at scale.Connected electronics require continuous power, which until now has meant batteries that must be periodically replaced or recharged. Legacy photovoltaic technologies like amorphous silicon cells long used on solar calculators and childrens toys don’t yield sufficient power in the real-world, low light operational conditions for most IoT sensors. At the same time, the exorbitant price tag for high performance, low-light PV technologies like gallium arsenide cells has made them suitable only for space satellite and research applications, not mass-market electronics.Ambient has solved both the low power density and high cost problems of legacy low light PV technologies and created the world’s most powerful low light energy harvesting photovoltaic cells — making endless power for IoT electronics a reality for the first time. | $30M | Series A | Sep 05, 2023 |  |
