| Marvel Fusion is a developer of fusion energy technology used to offer environment-friendly and safe energy. Its reactor is based on the short pulse, high energy, and electrically efficient laser that is suited for commercializing baseload fusion electrical power helping consumers to access clean, safe, and reliable energy sources.The company wasfounded in 2019 and is headquartered in Munich, Bayern. | $40M / Series A / Feb 03, 2022 | ||
| Avnos is commercializing technology to capture CO2 without consuming water, producing water for every ton. The company uses water to capture CO2, eliminating heat consumption and reducing costs. | Seed / Jan 01, 2022 | ||
| Loam Bio is a developer of microbial carbon sequestration technology for soil carbon restoration. Crops can be inoculated with symbiotic microorganisms that live in a mutualistic relationship with crops and build organic carbon in the soil, allowing farmers to improve the host plant's fertility and disease resistance while also assisting thesoil around the plant's roots to store carbon more effectively, resulting in proper quality soil for future planting. Loam Bio was established in 2019 by Guy Hudson. | $30.1M / Series A / Oct 28, 2021 | ||
| General Fusion pursues a commercially oriented path toward fusion energy by developing a magnetized target fusion (MTF) technology. The company applies advances in plasma physics, modern electronics, materials, and compression mechanisms to generate fusion-relevant conditions. It operates a demonstration system, Lawson Machine 26 (LM26), thatinjects magnetized plasma into a liquid metal liner and compresses it using coordinated mechanical pistons to reach high temperatures and pressures. The technology serves as a practical stepping stone toward building a fusion demonstration facility and ultimately delivering fusion-derived electricity to the grid. The approach focuses on closing the gap between demonstration milestones and a deployable power-plant system. | Venture - Series Unknown / Jan 14, 2021 | ||
| CarbonCure Technologies creates, develops, and licenses solutions that consume waste CO2 to make better concrete. It spurs the market shift towards affordable green concrete, by enabling concrete manufacturers to convert waste CO2 into solid minerals, locked away as a solid within concrete during manufacturing. It is a green building technologycompany currently serving concrete product manufacturers in the US and Canada. It offers concrete producers the ability to manufacture green concrete products without compromising on either quality or price.CarbonCure is a retrofit innovation that repurposes CO2 gas from large final emitters as a feedstock in concrete plants. The gas is permanently converted into embedded solid mineral carbonates that yield material, environmental, and production advantages. By enabling concrete manufacturers to consume CO2 into concrete products during manufacturing, the technology differentiates an otherwise traditional commodity concrete product, while achieving superior material performance characteristics. In addition to technology, CarbonCure provides demand-pull marketing and environmental reporting/certification services to reinforce its customers’ exclusive competitive positioning. The technology is licensed at a very low-CAPEX to concrete producers, generating a recurring revenue stream.CarbonCure Technologies was founded in 2007 and is headquartered in Halifax, Nova Scotia. | Venture - Series Unknown / Sep 17, 2020 |
