Zurich, Switzerland · StartupClimeworks is a Swiss climate tech pioneer specializing in direct air capture (DAC) of CO₂ – essentially technology to filter carbon dioxide directly out of the atmosphere. Founded in 2009 as a spin-off from ETH Zürich by engineers Jan Wurzbacher and Christoph Gebald, Climeworks has the distinction of building the world’s first commercial DAC plants. Its modular CO₂ collectors use a special filter that binds CO₂ when air passes through, then releases pure CO₂ when heated, allowing it to be captured and stored or reused. In 2017 Climeworks opened a prototype DAC plant in Iceland in partnership with Carbfix, where captured CO₂ is injected underground and mineralized into rock. By 2021, they launched “Orca” in Iceland – the largest DAC plant at the time – able to remove 4,000 tons of CO₂ per year, selling carbon removal as a service to corporate clients like Stripe, Microsoft and Shopify. Climeworks gained widespread attention as the first DAC unicorn: in April 2022 it raised $650M in an equity round (Europe’s largest-ever climate tech funding) at a valuation reportedly around $2 billion. Investors include Carbon Removal Partners and Big Oil venture arms, reflecting broad interest in negative emissions tech. As of 2025, Climeworks is scaling up “Mammoth,” a 36,000 tCO₂/yr plant in Iceland, and planning multi-megaton facilities by 2030. The EU and US policy push for carbon removal (with 45Q tax credits, etc.) strongly benefits Climeworks. The company also sells captured CO₂ for reuse in drinks and agriculture (a smaller market) and operates demonstration units in countries like Switzerland and Italy. With global climate goals increasingly reliant on carbon removal, Climeworks is positioned as a leader in an emerging industry. It touts a goal of removing 1% of global CO₂ emissions by 2050. While challenges remain (DAC is energy-intensive and currently expensive, around $600/ton), Climeworks has achieved real progress – turning sci-fi into reality. Its name comes up frequently in climate policy discussions, and it was highlighted at COP26 as an example of scalable climate innovation. In summary, Climeworks is a trailblazer in direct air capture, turning a bold lab idea into the world’s first commercial carbon removal service, putting Zurich on the climate tech map.

Paris, France · StartupNeoplants is one of Europe's most consumer-friendly deep-tech startups, known for engineering "plants with a purpose." Its flagship product, Neo P1, is a golden pothos that has been genetically modified to actively metabolize volatile organic compounds (VOCs) such as formaldehyde and benzene—pollutants common in homes due to paint, furniture, and cleaning products. Rather than simply filtering air passively, the plant converts toxins into harmless sugars and amino acids, turning living organisms into functional indoor air purifiers.
The company began commercial sales in the United States, where GMO consumer regulations are more permissive, but 2026 marks a strategic pivot back to Europe. Neoplants is positioning itself to launch in the UK and select EU markets as the New Genomic Techniques (NGT) framework evolves. This regulatory shift is crucial: it could unlock a path for consumer biotech products to be sold in Europe at scale. Neoplants is actively engaging with regulators and policymakers to ensure its products meet safety and transparency standards, framing its technology as a climate and public-health benefit rather than a controversial GMO niche.
Neoplants is also a serious biotech company under the consumer-friendly brand. It operates a 12,000-square-foot R&D facility in Saint-Ouen, Paris, with capabilities closer to a pharma lab than a greenhouse. The 2026 R&D pipeline includes plants engineered to capture CO2 at orders-of-magnitude higher rates than typical trees, targeting corporate offices and commercial spaces where sustainability investments must be visible and measurable. That positions Neoplants for a dual-market strategy: consumer air purification today, B2B climate infrastructure tomorrow.
The company's ecosystem roots are strong. The founders, Lionel Mora and Patrick Torbey, met at Entrepreneur First in Paris, and Neoplants was an early resident at Station F. It also benefited from the Wilco healthcare and biotech accelerator. Its investors reflect the blend of deep-tech and consumer focus: True Ventures led the seed, Heartcore Capital and Collaborative Fund support the consumer angle, and angels such as Niklas Zennstrom and Xavier Niel provide strategic visibility. In 2026, Neoplants represents a "solarpunk" vision of European tech—advanced biology that is both functional and approachable, turning climate and health solutions into products people can live with.

Stockholm, Sweden · StartupNorthvolt is a Swedish battery manufacturer founded to build a European supply of sustainable lithium-ion cells. In November 2024, Northvolt AB filed for Chapter 11 protection in the United States to pursue a financial restructuring while seeking strategic solutions for Northvolt North America. On March 12, 2025, the company filed for bankruptcy in Sweden and a trustee was appointed to oversee the process. Northvolt remains a landmark industrial project for Europe’s battery ambitions, but its current status is restructuring and insolvency rather than a typical growth-stage startup.

Stockholm, Sweden · StartupStegra (formerly H2 Green Steel) is one of Europe’s most ambitious industrial decarbonization projects, aiming to rebuild steelmaking around renewable energy and green hydrogen. The company is building a fully integrated production campus in Boden, northern Sweden, where abundant hydropower and regional mining supply chains converge. The core innovation is the direct-reduction process: instead of using coal to reduce iron ore, Stegra uses green hydrogen, cutting CO2 emissions by roughly 95% compared with blast-furnace steel. That technical shift is the foundation for a new European supply of low-carbon steel, which is increasingly demanded by automakers, construction firms, and consumer brands. The company rebranded to Stegra in September 2024 to signal that it is more than a steel mill. Its long-term platform vision is to combine renewable power, hydrogen production, and mineral processing into a repeatable template for heavy industry. By 2026, the Boden plant is reported to be more than halfway constructed, with gigascale electrolyzers (supplied by Thyssenkrupp Nucera) being installed and key offtake contracts signed. Customers reportedly include Porsche, Mercedes-Benz, Scania, and IKEA, and more than half of initial output has been pre-sold — a strong indicator that the “green premium” market is real. Stegra’s financing structure is as notable as its technology. Rather than relying solely on venture capital, the company blends project-finance debt with growth equity, totaling more than €6.5 billion in commitments. This makes it one of the largest private industrial raises in Europe and a flagship case for climate infrastructure funding. Its origins are tied to Vargas Holding, a Swedish venture-builder that also co-founded Northvolt and Polarium, acting as an institutional co-founder rather than a conventional accelerator. Early support from EIT InnoEnergy helped validate the project at the EU level. Stegra’s investor roster reflects its strategic importance: Altor Equity Partners, GIC, Just Climate, Temasek, and Porsche SE are among its backers. In 2026, Stegra represents the “Northvolt effect” done right: a proof that Europe can re-industrialize around clean energy and keep advanced manufacturing on the continent. If it succeeds, it will be a template for decarbonizing other hard-to-abate sectors, from cement to fertilizers, and a cornerstone of Europe’s green-industry competitiveness.

Dunkirk, France · StartupVerkor is the industrial champion of the French "Battery Valley" and one of Europe's most important energy manufacturing plays. While many battery startups emphasize chemistry R&D, Verkor's differentiator is execution at scale. Its gigafactory in Dunkirk, which began commissioning in late 2025, is designed to reach 16 GWh of annual capacity—enough to power roughly 300,000 electric vehicles. The facility is among the most advanced battery plants in Europe, built to supply automotive OEMs with locally produced, low-carbon cells.
The year 2026 is Verkor's start-of-production milestone. Its cells are the core of the new Alpine A390 and other Renault Group EV programs, giving the company a high-profile anchor customer and a direct path to volume demand. Verkor positions itself around "low-carbon performance" by combining France's low-emission nuclear grid with a highly digitized Industry 4.0 production system that reduces scrap rates and energy intensity. The company argues that its batteries carry a materially smaller carbon footprint than cells manufactured in coal-heavy regions, which is increasingly important as automakers track embedded emissions across supply chains.
Beyond production, Verkor is investing in future chemistry and process innovation. The Verkor Innovation Centre (VIC) in Grenoble is expanding its work on next-generation chemistries, including sodium-ion cells that reduce reliance on lithium and cobalt. This R&D focus strengthens supply-chain resilience and creates optionality for lower-cost, lower-risk storage solutions as electric mobility scales. Verkor's roadmap also includes tighter integration between materials sourcing, cell design, and recycling, positioning it to meet Europe's stringent regulatory requirements on battery sustainability and traceability.
Verkor is backed by a mix of strategic and infrastructure capital. Macquarie Asset Management and Meridiam provide long-term project finance muscle, Renault Group anchors demand and industrial validation, EQT Ventures provides growth capital, and Sibanye-Stillwater supports raw material security. It was co-founded and supported early by EIT InnoEnergy and has strong operational ties to Schneider Electric, which helped design its digital factory systems. With support from the Macron administration and the European Investment Bank, Verkor has become a poster child for European industrial sovereignty. In 2026, it stands as proof that Europe can manufacture critical clean-tech hardware at global scale—and do it with a lower-carbon footprint.
