| ARC Clean Energy | ARC Clean Energy is a clean energy technology company that offers safe, reliable, and economical carbon-free power. It is developing the ARC-100, an advanced small modular reactor (SMR). It leverages the proven technology developed by the US government’s Argonne National Labs, which operated successfully for thirty years in Idaho. The ARC-100’ssimple, modular design provides 100 megawatts of electricity that is cost-competitive with fossil fuels. The ARC-100 has been selected by New Brunswick Power in Canada for implementation on their Point Lepreau site with completion targeted for the late 2020s. | $15M | Series B | Dec 16, 2025 |  |
| Ion Membranes | Ion membranes is a company that designs and manufactures ion exchange membranes and separators for the green energy industry. Our products are used in batteries, electrolyzers, fuel cells, chlor-alkali facilities, electrodialysis water treatment processes, and other applications that require ionic range separation. | $750K | Seed | Nov 23, 2023 |  |

| Ratio Energy | Ratio Energy creates battery energy storage facilities, energy management systems, and software for energy optimization in the field of renewable energy. Its objective is to bring a strong mathematical and creative spirit into renewable energy. | $477.2K | Pre-Seed | Oct 10, 2023 |  |
| Ni-CAT Battery Materials and AI Company | Ni-CAT is working on AI-assisted research and development of next-generation battery materials, which is the key to the transition to battery electric vehicles. Ni-CAT believes that the speed of EV transition is still not enough to prevent global warming and replace carbon-based fuels in near future, and it is not related to money or resources. Webelieve that speeding up EV transition is possible with our novel methodology, which combines three approximation to the solution: our unique AI-assisted materials research, digitalized reactor farm and our novel surfactant-assisted synthesis.As the electrification of the automotive industry expands, we deliver state-of-the-art technologies to meet the industry’s high-quality standards. To help our customers to step up the EV transition, we will be working on our research and development of lower-cost/higher performance, ultra-high energy density battery materials to serve innovative solutions for a brighter future. With our expertise in the application of machine learning in material science, we are developing low cobalt/high nickel lithium cathode materials. Cathode determines the type of a lithium battery and is the limiting factor for nickel-based batteries. Further improvement in battery performance is possible through AI-assisted custom high nickel cathode materials with increased charge rate, charge to discharge ratio, tap density, or any other specifications. By our unique computer-controlled digital reactor farm, we numerize synthesis parameters and output specifications for the machine learning algorithm we have been developing. | $197.1K | Seed | Sep 20, 2022 |  |
