Founded in 2019, Aircela has developed a modular system that integrates direct air capture, electrolysis and hydrocarbon synthesis (Fischer–Tropsch or methanol-to-gasoline pathways) to produce liquid e-fuels compatible with conventional engines. In spring 2025 the company installed a refrigerator-sized prototype in Manhattan capable of roughly 3.8 liters per day of gasoline production while capturing about 10 kg of CO2 daily, and it maintains a waitlist for commercial units. Aircela emphasizes decentralized deployment to place production near points of consumption and reduce logistics for sectors like aviation, maritime and heavy machinery. Financially, the company has raised US$5.5 million in a Seed round with strategic backing from Maersk Growth and prominent individual investors. The startup positions its e-fuels as a complementary solution to electrification for hard-to-electrify applications and is using its recent funding to advance commercialization and scale modular unit deployments.

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.

Kvasir Technologies is a DTU spin-out that has developed a patented process to convert non-edible lignin-based residues from agriculture and forestry into refined, climate-neutral fuels intended as direct replacements for conventional marine fuels. The company operates a test facility in Fredericia with up to two tonnes-per-day production capacity and plans a commercial-scale demonstration plant in Aabenraa. Kvasir recently raised €10 million in a Series A to fund scale-up and commercialisation and has secured a strategic partnership with European Energy to form KVEEN Biofuels. The technology is positioned to be used within existing ship engines and infrastructure, aiming to lower barriers to adoption in the maritime sector. Existing investors EIFO, Mærsk Growth, and Footprint Fund participated in the round alongside new investment from European Energy.

Founded in 2022 and operating between Paris and Strasbourg, Nabu offers a platform that converts client documents and instructions into compliant customs declarations and automated workflows. Its AI-based system aims to reduce manual workload, improve speed and accuracy, and handle declarations significantly faster with fewer errors. The platform is used by a wide range of organisations, from independent customs brokers to large international transport groups, and a growing share of activity already takes place outside France. Nabu plans to continue enhancing automation and user experience and to extend its functionality beyond customs declarations to cover additional cross-border formalities as it expands across Europe.

Fleetzero is a marine technology company that sells Leviathan™ electric and hybrid propulsion systems that can be retrofitted onto existing ships or installed on new builds. The system is marketed as cheaper, safer and cleaner than traditional marine powertrains, delivering maintenance and fuel savings while enabling future autonomous operations. The firm is also developing unmanned cargo vessel technology, positioning electrification as a key enabler for marine autonomy. Fleetzero recently opened a Houston, Texas headquarters that houses manufacturing, an R&D center and a marine robotics lab. The first production line has an annual capacity of 300 MWh of marine energy-storage systems, with plans to scale to 3 GWh per year within five years. The company believes its high-volume manufacturing approach can help revive U.S. and European shipbuilding. Commercial deployments of the Leviathan™ system are already underway with global vessel operators.
