Blue Current is a battery technology company focused on commercializing silicon solid-state batteries that eliminate flammable liquid electrolytes. Its platform pairs earth-abundant silicon and elastic polymer anodes with fully dry electrolytes, yielding improved energy density, faster charge rates, inherent safety, and operation at low pressures. The design can be manufactured on existing lithium-ion battery equipment, positioning the product for cost-effective, domestic scale-up across electric mobility and stationary storage markets. After more than a decade of research and development, the company operates from a headquarters and pilot line facility in Hayward, California. With safety as a guiding principle, Blue Current’s batteries aim to reduce fire risk while extending cycle life and charging performance. The newly raised capital moves the firm into a full commercialization phase, enabling multiple high-value use cases across energy-reliant industries.

Zero Industrial is a development company focused on decarbonizing industrial heat by deploying commercially available thermal energy storage (TES) systems at industrial facilities. The company provides full project development services including technology selection, project design, and engineering for each TES system. Zero Industrial will fully finance projects and sell clean heat or steam to customers under long-term Heat-as-a-Service contracts without requiring upfront capital from the industrial facility. Founded in 2024 and based in Charleston, S.C., the company is actively originating and developing projects in the United States and Canada and is exploring additional international markets. Management plans to accelerate deployment of TES projects in North America to shift curtailed or off-peak clean electricity into baseload heat and steam, reducing energy costs and emissions. The company recently closed a $10 million financing to support project development and deployment.

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.

Avnos is commercializing its proprietary Hybrid Direct Air Capture (HDAC) system, a water-positive approach that simultaneously captures atmospheric CO₂ and produces clean water, eliminating two major cost barriers—external heat and water consumption—found in conventional DAC systems. HDAC’s efficiency and geographic flexibility allow deployment across diverse industries and locations, and the technology is now being scaled through Project Cedar, a flagship U.S. facility slated to be operational by the end of 2026. The plant will deploy four HDAC modules capable of removing 3,000 metric tons of CO₂ and generating over 6,000 tons of water annually. Backed by partnerships with Shell, Mitsubishi Corporation, the Office of Naval Research, and the U.S. Department of Energy, Avnos has secured more than $100 million in combined private and public funding to date. The company is headquartered in Los Angeles and positions its water-generating, energy-efficient process as a repeatable blueprint for global carbon-removal infrastructure.

Carbon Engineering develops large-scale Direct Air Capture (DAC) technology that extracts CO2 from the atmosphere for permanent geologic storage or to produce sustainable fuels. The company focuses on improving efficiencies and reducing costs through ongoing technology development at its CE Innovation Centre. The CE Innovation Centre in Squamish, British Columbia is described as the world’s largest dedicated DAC research and development facility. Recent investments from Airbus and Air Canada will fund CE’s technology development efforts to accelerate scalable, affordable decarbonization solutions. CE highlights two aviation pathways enabled by DAC: carbon dioxide removal (CDR) and sustainable aviation fuel (SAF) made from atmospheric CO2 that is drop-in compatible with existing aircraft. With partners, CE is working to deploy large-scale commercial DAC facilities in multiple markets around the globe. Carbon Engineering develops Direct Air Capture and Air To Fuels technologies that remove CO₂ from the atmosphere and convert it into low‑carbon intensity fuels. The company has been capturing CO₂ since 2015 and began converting captured CO₂ into fuels in 2017. CE plans to construct and operate the Newport Innovation Centre in Squamish, containing an advanced development facility and a fully integrated plant for both technologies. The government-funded plant will be capable of capturing 4.5 tonnes of CO₂ and producing at least 320 litres of ultra‑low carbon fuel each day; CE states commercial plants could capture one megatonne of CO₂ per year and produce over 100 million litres of fuel annually. Financially, CE recently closed a private investment round in March totalling CAD$90 million and has received earlier investments such as $3 million from Sustainable Development Technology Canada in 2015. The company will continue core R&D and begin design and engineering of commercial plants, with support from multiple government programs and innovation funds. Carbon Engineering develops and commercializes direct air capture (DAC) technology that captures and purifies atmospheric CO₂ and an AIR TO FUELS™ process that converts captured CO₂ into ultra‑low carbon transportation fuels. Its pilot plant in Squamish, B.C. has been removing CO₂ since 2015 and converting it into fuels since 2017. CE’s DAC process has been demonstrated at costs under USD$100 per tonne and the company says industrial‑scale facilities could capture up to one million tonnes of CO₂ per year. The company plans to scale from pilot demonstration to mainstream market deployment by expanding its Squamish pilot plant and engineering its first commercial facilities. The $68M equity financing announced will finance commercialization activities and bridge the company from pilot to industrial deployment. CE emphasizes both permanent underground CO₂ storage and fuel synthesis as complementary pathways for large‑scale negative emissions and emissions‑reduction in transportation. Carbon Engineering develops and commercializes Direct Air Capture technology to remove CO₂ from the atmosphere and convert it into synthetic transportation fuels. From a pilot plant in Squamish, B.C., CE has been removing CO₂ since 2015 and converting it into fuels since December 2017. The company reports its Direct Air Capture can capture CO₂ at scale for less than USD $100 per ton. CE's AIR TO FUELS™ process combines captured CO₂ with clean electricity to produce ultra‑low carbon fuels. It plans to expand its working pilot plant and design its first commercial AIR TO FUELS plant, with a full commercial facility capable of producing 320,000 litres of synthetic fuel per day and capturing one million tons of CO₂ per year. Headcount increased 33% in the prior six months as the company scales operations and seeks strategic partners and customers for supply agreements.
