Pronoe is a CO2 removal company. We restore the ocean’s natural ability to capture and permanently store CO2 from the air, in a sustainable, scalable and asset-light manner. In practice, we design automated water treatment systems that seamlessly integrate into the operations of existing coastal industries. As a result, Pronoe’s activities generate high-quality CO2 removal certificates to customers, valorize otherwise wasted effluents, and locally mitigate ocean acidification. To the benefit of the climate, coastal communities and ecosystems, worldwide.

We develop unmanned electric boats to innovate in the maritime sector.

Eco-friendly aquaculture for sustainable seafood production.

The pioneering, eco-friendly technology performs sophisticated water bottom cleaning in the most cost and time-efficient way, providing a positive impact on the environment. PurOceans can clean up floors of the water bodies from oil, microplastic and chemical sediments without: Applying any bio/chemical substances, Mechanical intervention/lifting of soil, Using electric impulses, Other nowadays methods, that one way, or another, harm flora and fauna. And, it has a number of advantages: New technology - eliminate the pollution from waterbodys floor on the depth of 25 meters (in future up to 200 meters depth), Provide efficient cleaning (proven results - 98% of water/floor purification), Eco-friendly solution no chemical/mechanical intervention, No adverse effect - no damage to flora & fauna in any way. How it works: The technology is based on the principle of FLOTATION (molecular adhesion of petroleum hydrocarbons to the boundary between two phases air and liquid).

Our ongoing project focuses on the development and deployment of Quantum Key Distribution (QKD) devices. By integrating cutting-edge fiber-based and free-space transceivers leveraging the principles of quantum physics, we contribute to the sustainable growth of the blue economy. These secure cryptographic key exchange solutions not only safeguard sensitive data but also support marine innovation and environmental conservation, aligning with the principles of responsible resource management and economic development within coastal and marine sectors.

The Missing Link to Scalable and Sustainable Fish Farming The global demand for aquatic protein is growing rapidly, yet the aquaculture industry faces a critical barrier to sustainable expansion: poor fish health and welfare, resulting in high mortality, disease outbreaks, and unstable production. Despite advances in nutrition, technology, and system design, fish farmers still lack the tools to systematically monitor and control the fish’s immune system—the very foundation of resilience and productivity. QuantiDoc’s VeriBarr™ solution fills this gap. Backed by over 12 years of scientific research and development, VeriBarr™ is the world’s first standardised technology for continuously monitoring the outer immune system in fish. The solution analyses barrier tissues—gills, skin, and gut—which act as real-time biomarkers for health status. These tissues are the first to respond to environmental stressors such as water quality, feed, handling, and disease agents. QuantiDoc’s proprietary database, developed from thousands of samples across 13 commercially important fish species, now enables farmers to benchmark fish health against scientifically validated reference intervals. VeriBarr™ transforms biopsies into actionable insights, making early intervention and production optimisation possible for the first time. In the words of a recent feature in iLaks, Norway’s leading aquaculture news outlet: "You will not succeed with industrial fish farming without monitoring the immune system." Link (in Norwegian) : https://ilaks.no/man-vil-ikke-fa-til-industriell-oppdrett-uten-a-overvake-immunforsvaret/ The Challenge: Despite billions invested in technology, the fish farming industry has lacked the ability to detect when fish are transitioning from healthy to vulnerable. This often results in late interventions, high losses, and compromised welfare. Regulators and consumers are demanding higher standards of animal health and transparency, while investors seek more predictable outcomes. The Opportunity: QuantiDoc’s technology is ready to scale. With contracts in place, and successful pilot projects showing mproved biological control, we are at a tipping point. By implementing VeriBarr™, fish farmers can: 1. Detect early signs of stress and disease weeks before clinical symptoms 2. Reduce mortality and improve growth 3. Optimise environmental conditions and operational practices 4. Certify health and welfare throughout the production cycle Deliver better economic outcomes and greater sustainability Strategic Goal: QuantiDoc aims to become the global standard for immune system surveillance in aquaculture. Our technology directly supports the EU’s Blue Economy goals by enabling resilient food systems, better resource use, improved animal welfare, and reduced environmental impact. With BlueInvest support, QuantiDoc will scale operations, accelerate digital integration, and expand into international markets where healthy fish = sustainable food. VeriBarr™ isn’t just a tool. It’s the foundation of scalable and responsible aquaculture.

In our innovation-driven startup, KorallionBio, microalgae take centre stage. For each sustainability question we meticulously select the ideal microalgal strains and optimise the growth, induction of biosynthesis and downstream processing methods in order to bring novel biobased products to market. The idea is simple: KorallionBio‘s cascade approach focuses on maximizing the value from a production process by using every part of the materials involved. It starts with creating an initial product, where anything not used is typically considered waste. In the next step, this leftover material is further processed to extract any remaining useful products or ingredients. At this point, KorallionBio steps in using microalgae, which convert the remaining nutrients and molecules in this waste into high-value biomolecules. This final step ensures that all possible value is extracted and nothing goes to waste.

Recycllux offers the first fully integrated, data-driven solution for marine plastic waste management, combining Earth Observation (EO), AI, and Blockchain to provide real-time waste detection, targeted interventions, and full traceability. Unlike traditional cleanup efforts that rely on manual collection and fragmented reporting, Recycllux automates waste identification, optimizes collection logistics, and ensures verifiable impact reporting through blockchain technology. This end-to-end approach — from detection and collection to recycling and impact reporting - helps companies, coastal authorities, and ports demonstrate sustainability efforts transparently and efficiently and streamlines compliance with regulations.

RedoCell aims to revolutionise the power supply for container ships by developing high-capacity battery units with up to 75 MWh of storage capacity, each configured in a standard 20-foot transport container. At the heart of our technology are innovative fuel cells specifically designed to optimise the use of our advanced energy materials. Complemented by our simple plug-and-play principle, shipping companies can reduce their energy costs without risk, while meeting their emissions targets, and without the need to modify their vessels. We aim to offer a flexible pay-per-use pricing model to create a sustainable and future-proof energy strategy for the maritime industry. This will enable ship operators to make their fleets sustainable and competitive.
