Valar Atomics is developing advanced nuclear reactors intended for scalable deployment and is pursuing clusters of small reactors—sometimes called "gigasites"—to serve high-demand users such as data centers and manufacturing. Founded in 2023 and based in California, the company is also exploring applications beyond grid electricity, including producing synthetic fuels and supplying industrial heat. Its technology and commercial approach target energy-intensive industries and the growing electricity needs driven by AI infrastructure. Financially, Valar recently raised approximately $450 million (about $340 million equity and $110 million debt) at a reported $2 billion valuation, following a prior $130 million raise in 2025. The company is backed by defense-tech investors including Palmer Luckey and Shyam Sankar.

Solestial develops silicon solar cells engineered for space that can self-cure radiation damage and are packaged in ultrathin, low-mass, flexible solar power modules. The modules can be produced on automated machines at costs lower than traditional III-V multijunction products and are designed to last up to 10 years in various space destinations. Since opening its Tempe, Arizona manufacturing facility in 2023, the company has added square footage each year, more than doubled its workforce, and delivered commercial products to dozens of companies. The company is scaling manufacturing to 1 megawatt per year — a rate the company says is comparable to the estimated annual manufacturing capacity of all US and EU III-V space solar companies combined. Solestial says it is hiring, scaling production, and qualifying its technology amid strong market demand across satellite constellations, lunar exploration, national security, and other missions. Leadership changes accompanying the fundraise include the appointment of Margo de Naray as CEO and the founding CEO Stanislau Herasimenka moving to CTO to focus on the product roadmap and operations technology. Solestial develops space-grade solar panels using inexpensive, scalable terrestrial manufacturing processes with the goal of cutting costs to roughly one-tenth of standard III/IV panels. Its core cell technology uses low-temperature heat curing (80°C) that can self-cure radiation damage, a feature validated at prototype stage. The company is now focusing on full panel assemblies, including interconnects and extra-thin silicon substrates, and is subjecting those assemblies to accelerated stress testing to demonstrate multi-year orbital lifetimes. Solestial has delivered several small panels for demo flights while customers help the firm build flight heritage and validate mass-production readiness. Management targets mass production in about two years with the capacity to produce tens of thousands of panels to serve satellite constellations and larger space installations. Financially, Solestial raised a $10M seed and previously received roughly $2.5M in SBIR awards to validate the technology. The company rebranded from Regher Solar to reflect plans to expand beyond panels into broader in-space power solutions over time.

MetOx manufactures high-temperature superconducting (HTS) wire using proprietary processes to produce its scalable, high-performance Xeus™ wire. The company's Xeus wire targets applications in renewable energy, fusion energy, high-field magnets, and electrification of the power grid. MetOx is expanding its Houston, Texas production line to scale large‑scale production of Xeus wire. The company emphasizes building domestic manufacturing capacity to advance grid modernization and create quality manufacturing jobs. MetOx has partnered with Elemental Impact to accelerate production and deployment of its HTS technology. MetOx develops High Temperature Superconducting (HTS) technology and is focused on scaling domestic HTS manufacturing capacity. The company plans to build additional high-capacity HTS manufacturing facilities in the U.S. to improve production efficiency, scale, and supply-chain security. MetOx positions its technology for power transmission, grid expansion, renewable energy, hyperscale data centers, AI applications, and fusion energy. The company is partnering with the U.S. Department of Energy and strategic investors to advance clean-technology manufacturing. Its recent financing activity and an $80 million DOE grant are intended to accelerate manufacturing scale-up, job creation, and a more resilient HTS supply chain. MetOx is headquartered in Houston and emphasizes domestic production to meet surging market demand. MetOx International develops and manufactures high-temperature superconducting (HTS) wire using proprietary production technologies. Led by CEO Bud Vos, the company is accelerating manufacturing scale-up to supply HTS solutions across energy transmission, wind power, fusion energy, medical applications, aerospace, and defense. MetOx leverages its proprietary production methods to deliver lightweight, high-power solutions aimed at enhancing energy infrastructure and supporting emerging applications. The company intends to use new capital to expand operations and advance its development efforts. Financially, MetOx has closed a $25M Series B extension to support that scale-up. The funding is intended to help the company commercialize and scale its manufacturing capabilities for a range of high-demand HTS markets. MetOx Technologies manufactures high-temperature superconducting (HTS) wire using an enhanced and patented manufacturing process. The company is based in Houston, Texas and sells large quantities of HTS at prices intended to support widespread adoption. Proceeds from a recently completed $23 million Series A will be used to construct an advanced production facility expected to produce approximately 1,200 kilometres per year of HTS wire, roughly doubling 2020’s global supply of magnet wire. MetOx says its production system targets a cost-effective, scalable supply to address current shortages as mainstream use of superconductors grows. Management highlights applications including grid expansion, compact fusion, and powerful new medical devices among other uses. Fort Capital Partners acted as financial advisor for the Series A.

Carbon Ridge, based in Los Angeles, is focused on designing modular onboard carbon capture and storage (OCCS) systems that can be retro-fitted into vessel exhaust lines. The technology is engineered to cut carbon dioxide and other greenhouse-gas emissions from ships by up to 95% while shrinking equipment size and volume by as much as 75% compared with conventional CCS approaches. In addition to the capture hardware, the company offers an end-to-end service stack that covers CO₂ transportation, permanent sequestration, and credit monetization. Carbon Ridge positions its OCCS platform as a low-cost, near-term route for maritime decarbonization that avoids operational disruption for ship owners. The firm plans to use its latest capital infusion to complete development and launch an onboard pilot in 2023. Prior to the recent raise, no other funding figures were disclosed in the article, leaving the company at an early stage of commercialization.
