  Participated · Series A · Sep 2024

  Eion develops and deploys enhanced rock weathering (ERW) on agricultural lands, applying olivine and routine farming practices to capture carbon while balancing soil pH. The company holds an industry-first patent for directly measuring carbon removed by mineral weathering in soils using immobile trace elements, and relies on routine soil samples and standard equipment to monitor removal and soil conditions. Led by CEO Anastasia Pavlovic, Eion emphasizes integrating with existing agricultural systems to scale without compromising safety or rigor. The company is focused on commercial deployment, delivering against new contracts, and continuing R&D to improve measurement and application methods. Eion is targeting to deliver 10 million tons of permanent carbon removal annually starting in 2030 and aims to create stable jobs in rural communities. Eion commercializes CarbonLock, a pulverized olivine soil amendment that sequesters CO2 via enhanced rock weathering (one ton applied can absorb one ton of CO2). The olivine is mined in Norway, shipped to Mobile, Alabama, crushed to increase surface area, and applied to fields typically once every two years at roughly two tons per acre. CarbonLock also acts as an agricultural lime, reducing soil acidity, which helps farmer adoption. Eion validates sequestration by tracking the fate of olivine through measurements of magnesium and rare earth elements and monitors for heavy metals like nickel and chromium. The company is finalizing its methodology, expanding operations, and planning to build a mill to scale production. Current revenues have been supported by carbon-credit buyers such as Stripe’s climate program; Eion is exploring additional revenue sources including payments from farmers or food brands, potential federal cost-sharing, and has an off-take agreement with mineral supplier Sibelco.

  Voltpost retrofits existing lampposts into a modular, upgradable Level 2 EV charging platform designed for rapid, low‑cost curbside and parking lot deployments. The system is powered by a mobile app and emphasizes minimal installation time, no trenching, and a small physical footprint. Voltpost positions its product to generate new municipal revenue streams, provide infrastructure data for city planning, and accelerate EV adoption—particularly in underserved urban areas. The company highlights the ability to install chargers in about an hour, enabling faster rollout compared with traditional curbside solutions. Voltpost has run demonstrations with drivers, OEMs, and government agencies, maintains a demo unit at Newlab at Michigan Central, and participated in Plug and Play Detroit Mobility and associated pitch events. Its recent grant awards from Michigan programs support deployments in the Detroit metro area and broader Michigan market expansion. Voltpost designs sleeve-mounted chargers that tap into existing lamppost electrical feeds and dispense a 20-foot retractable cable from about eight feet, with the plug docked below for easy access. Each charger delivers 7.6 kilowatts and a single post can support two chargers; current hardware fits metal posts only. The team built its own equipment after customer discovery with city agencies and utilities found bring-your-own-plug designs failed UL requirements and drivers preferred integrated cables. Voltpost plans to sell to cities, utilities and private hosts, bundling installation, maintenance and operations into an annual fee while leaving per-session pricing to the host. The company is in talks with municipal, utility and private partners across the U.S. and hopes to launch initial pilots with one partner in each sector. Voltpost recently closed seed financing and intends to raise a Series A to scale after early deployments.
