Captura designs and manufactures a PFAS-free bipolar membrane electrodialysis platform that generates acid and base streams for applications including direct lithium extraction, industrial water treatment, long-duration energy storage, and CO2 management. The platform was originally developed to power Captura’s Direct Ocean Capture (DOC) system, which removes CO2 from seawater for permanent storage or utilization. Captura operates the only U.S.-based production plant that produces complete electrodialysis systems and plans to scale domestic manufacturing capacity following its Series B raise. The company reports that its technology offers greater performance with significantly lower energy consumption and capital costs compared with leading market alternatives. Captura recently secured multiple purchase orders for its first electrodialysis stacks addressing the lithium extraction market, with initial deliveries expected this summer. CEO Steve Oldham says the company is now manufacturing systems for customers while continuing to advance commercial deployment of DOC globally.

Inherit Carbon Solutions structures and develops carbon-capture projects and sells carbon removal certificates to corporate clients such as Microsoft, DNV and Nordea. The company acts as a facilitator across the value chain—sourcing CO2 from emitters (for example biogas at wastewater plants), arranging capture and liquefaction, transporting CO2 by truck to Øygarden and onward pipeline storage via Northern Lights. Inherit opened its first operational capture project at the Slemmestad wastewater facility and is working on a larger project in Denmark. Founders Kaja Voss (CEO) and Mike Carpenter each hold about 20% of the company. Financially, Inherit raised NOK 40 million in January in its third funding round, which valued the company at NOK 133 million pre-money and resulted in Equinor Ventures taking a 22% stake. The company reports navigating a tighter market for carbon credits and changing buyer dynamics but expects regulatory developments, particularly in the EU, to support demand over time.

Green2X develops technology that converts biomass into biomethane, positioning itself to become a leader in next-generation biofuels. Backed by fresh funding, the company is building a pilot facility on the island of Møn to validate and optimise its process. The pilot is a precursor to a full-scale plant in Vordingborg, budgeted at DKK 1.5 billion, which is projected to produce more than 175 million normal cubic metres of biomethane annually—about 10 % of Denmark’s current gas consumption. Green2X also plans to expand into Malmö after Vordingborg comes online, creating a broader Scandinavian production network. CEO Mikkel Sjølin Kiil emphasises that the business case remains attractive despite inflation, higher costs, and a volatile policy environment in renewable energy. The company ultimately seeks to establish a European green-energy hub and scale its biofuel solutions globally.

Lithium de France is building an industrial platform that couples deep geothermal energy production with direct-lithium-extraction (DLE) technology to supply low-carbon heat and battery-grade lithium from the same brine. Its first operational site is in Schwabwiller (Alsace du Nord), where drilling on the initial geothermal well began on 24 November. The company holds several Exclusive Exploration Permits, including “Les Sources,” and continues subsurface studies across the region; it also selected Sedgman to carry out the front-end engineering design for its initial commercial plant. A scientific partnership has been signed with France’s BRGM to refine resource models, and the firm recently secured its first lithium supply agreement with Renault Group. Backed by parent company Arverne Group, Lithium de France aims to supply local agriculture and industry with continuous clean heat while delivering strategic European lithium volumes. To fund these plans the company has completed multiple capital rounds, most recently a €44 million raise that follows an €8 million Series A first close and a separate €40 million project financing supported by Equinor Ventures. These proceeds are being deployed to finish drilling, advance detailed engineering, and move the Schwabwiller project toward commercial operation.

ElectronX is building the first U.S.-regulated, direct-access exchange and clearinghouse for electricity derivatives. In August 2025, it secured both Designated Contract Market and Designated Clearing Organization status from the CFTC, enabling it to list fully collateralized, centrally cleared power products. The platform will launch next month with 1 MWh hourly futures and binary options for the ERCOT market, giving traders and asset owners intraday hedging tools that mirror physical power strategies. Additional contract suites for PJM, CAISO and other RTOs/ISOs are planned for 2026. Headquartered in Chicago with an office in New York, the company aims to address short-term price volatility as electrification and renewable penetration accelerate. ElectronX has raised more than $55 million to date, capital that supports technology development, regulatory compliance and market rollout.
