Hyke
Hyke is a Norwegian zero-emission electric ferry startup founded in 2018 by designer and entrepreneur Bård Eker as a spin-out from Eker Group. Its lightweight, fully electric ferries use up to 88% less energy than diesel equivalents and are designed for autonomous operation in urban and inland waterways. The F-15 shuttle completed a 14-month public transport trial in Fredrikstad carrying over 41,000 passengers between April 2024 and mid-2025. Hyke supplied river shuttles for the Paris 2024 Olympic Games with backing from RIVE Private Investment, and former Norwegian Minister of Transport Ketil Solvik-Olsen joined as a key executive.
Hystar
Hystar is an Oslo-based green hydrogen company founded in 2020 as a spin-off from SINTEF. The company manufactures PEM (proton exchange membrane) electrolysers with membranes 90% thinner than conventional alternatives, significantly cutting electricity consumption and the levelised cost of green hydrogen. Hystar raised $36 million in a Series C round in May 2025 co-led by Nysnø Climate Investments and Orlen VC, building on a $26 million Series B in 2023. The company also secured €26 million from the EU Innovation Fund in late 2024 to support construction of a 1.5 GW automated gigafactory in Høvik, Norway, targeting 4.5 GW capacity by 2031.
IGC 2027 - Iceland Geothermal Conference
The Iceland Geothermal Conference (IGC) is a leading international event on geothermal energy, held at the Harpa Conference and Concert Centre in Reykjavik. The 6th edition, under the theme 'Geothermal for a Changing World', guides participants through the full geothermal value chain across four tracks: financing and policy, project development, next-generation technologies such as EGS, and community and societal impact.
Ilion Water Technologies
Developed Voltage Induced Reverse Osmosis (VIRO), a pressure-free desalination technology that uses a low-voltage panel to drive water through standard RO membranes, removing the need for high-pressure pumps. Spun out of ENS-PSL Paris.
Innovafeed
Produces sustainable insect-based ingredients from the Black Soldier Fly for aquaculture, pet food and plant nutrition. Founded in 2016, it has produced over 15,000 tonnes of protein and oil and secured €51M to scale commercial growth.
KLAK – Icelandic Startups
KLAK is a non-profit accelerator and entrepreneurship support organization founded in 2000, formed through the 2013 merger of Klak and Innovit. It is owned by the University of Iceland, Reykjavík University, the Kría Innovation Fund, and the Federation of Icelandic Industries. KLAK runs three to four sector-specific accelerator programs annually, operates the Gulleggið startup competition (Iceland's largest, with over 3,000 ideas submitted since 2008), and provides mentorship and international growth support to early-stage Icelandic companies.
Lanéva Boats
Monaco-based builder of electric leisure boats, working from Le Thalès on rue du Gabian with a second office in Nice. Lanéva designs and builds custom electric yachts, converts existing high-end vessels to electric or hybrid propulsion, and restores classic boats with modern drivetrains. It came through the MonacoTech incubator and positions itself around zero-emission pleasure boating.
Lech Kaniuk
Polish-Swedish serial entrepreneur who co-founded and scaled PizzaPortal (acquired by Delivery Hero) and the solar-roofing company SunRoof. He has founded more than ten companies, angel-invested in dozens of startups and authored three books on startup fundraising.
Luís Castro Henriques
General Partner at EDP Ventures, the corporate venture arm of Portuguese energy group EDP. He leads investments in renewable energy, grid, storage and energy-transition technologies, aligning startup innovation with EDP's decarbonisation strategy.
Luxembourg-City Incubator
An EU-accredited business incubator launched in September 2017 by the Chamber of Commerce with the City of Luxembourg as its main sponsor. Located at the House of Startups, it provides 2,000 m² of closed offices and open coworking areas for early-stage local and international startups. Focus sectors include urban tech, logistics, and environmental technology.
MannaEV
MannaEV is Malta's first electric motorcycle delivery and battery-swapping startup, founded in early 2023 by three co-founders with backgrounds from Google, Alibaba, TikTok, and Lazada. The company operates an on-demand same-day delivery platform powered by smart electric motorcycles and a battery-swapping network, eliminating range anxiety and enabling rapid fleet turnaround. Within its first year MannaEV scaled to 500+ customers and deployed 50+ electric motorcycles across three battery-swapping hubs on the island without external VC funding. It won multiple categories at the Malta Business Awards 2024 and has a commercial partnership with Bolt Malta.
Mosa Meat
Mosa Meat is a Maastricht-based food-technology company founded in 2016 by the team behind the world's first cultured hamburger, presented in 2013. It develops cultivated (lab-grown) beef produced from animal cells rather than slaughtered livestock, aiming to make real meat with a far smaller environmental footprint as it works toward regulatory approval and scale-up.
Naco Technologies
Naco Technologies develops proprietary PVD nano-coatings that replace expensive platinum-group metals in hydrogen electrolysers and fuel cells, reducing the cost of green hydrogen production at scale. Founded in 2010 by Aleksandrs Parfinovičs and Raivis Nikitins, the company secured €8 million in equity plus a €2.3 million EIC Accelerator grant in 2023, followed by a further €2.5 million pre-Series A round in 2025. Naco's coatings target bipolar plates, gas diffusion layers, and membrane electrode assemblies.
NanoSci
NanoSci is a Warsaw-registered Polish deep-tech startup, founded in 2020, that develops photocatalytic air-purification technology licensed to manufacturers of ventilation, lighting and transport equipment. Its core IP — researched at the University of Gdańsk under Prof. Adriana Zaleska-Medynska — is built on porous titanium dioxide (TiO₂) nanolayers and nanotube arrays activated by UV-LED light. The photocatalytic reaction generates hydroxyl radicals that continuously decompose volatile organic compounds, nitrogen oxides, odours, bacteria, viruses and fungi into harmless CO₂ and water vapour, with no replaceable filters and very low energy use. Rather than selling finished consumer devices, NanoSci provides modular photocatalytic engines to OEM and white-label partners; an early collaboration with bus maker Solaris demonstrated the technology in public-transport air conditioning. Two branded lines are now visible: Jupitair, targeting food and greenhouse environments (with deployments in Singapore and the Philippines and a place in Thailand's SPACE-F accelerator), and Airchanger, a decentralised heat-recovery ventilation unit with integrated purification. The company has raised early equity alongside Polish state grants and support from accelerators including AcceliCITY and Estonia's Beamline.

newcleo
newcleo develops Generation IV lead-cooled fast reactors (LFRs) fuelled by recycled nuclear waste, targeting a closed-fuel-cycle that dramatically reduces long-term radioactive waste. Founded in 2021 by Stefano Buono — previously founder of NASDAQ-listed nuclear medicine company Advanced Accelerator Applications, acquired by Novartis for $3.9 billion — newcleo has raised over $755 million to date, including $85 million in early 2026. The company is building PRECURSOR, a 10 MW non-nuclear lead-cooled test system at ENEA's Brasimone Research Center in Italy, with a full demonstration reactor planned for France by 2032 and €28 million invested in Turin research facilities.
