This roundup includes 13 achievements from the PortXL alumni community of innovative changemaker companies, published from February to April 2026. It fills us with pride and joy to see this progress.
CLCircular (PortXL ’24) has become the first logistics monitoring company using IoT sensing technology to obtain B Corp certification after demonstrating compliance with high standards of social and environmental performance, transparency, and corporate accountability. For further reading, see Source1.
Nanosieve (PortXL ’25) has received a Letter of Intent (LOI) to evaluate its technology for reducing methane slip and fugitive emissions from LNG systems and operations. See Source2.
Ensemble (PortXL ’22) partnered up with NoBa Capital and became part of their portfolio via their inaugural Elevate cohort. NoBa stated they backed Ensemble because “They understand the operational and economic realities of the environments they serve. They are not layering tech onto a surface problem. They are rebuilding how workforce data is structured, interpreted and acted upon.” See Source3. Ensemble was also highlighted by ZEBOX for their successful deployment of their Athena solution at RAK Ports. See Source4.
GBMS (PortXL ’22) published an update on their collaboration with CMA CGM. Through ZEBOX, the collaboration with CMA CGM was structured, the proof of concept was launched, and clear KPIs validated the impact of the solution. The value is proven, and now they will scale. Deployment is underway within the fleet center and onboard vessels. See Source5.
Eco Wave Power (PortXL ’19) passes real-world sea conditions test at Jaffa Port in Israel. The EWP-EDF One wave energy pilot project has maintained zero downtime, with consistent performance recorded in wave conditions of one meter and above since the beginning of 2025, according to Eco Wave Power. During January 2026, over approximately 11 days characterized by wave heights ranging between one and two meters, the project generated over 2,300 kWh of renewable electricity. See Source6.
SeaO₂ (PortXL ’24) was highlighted by the EU’s Directorate-General for Maritime Affairs and Fisheries (DG MARE) and introduced their next phase, planned for 2028: Project Breaker. It will introduce a commercial component, as it is designed to generate and deliver carbon credits. To fund this phase, SeaO₂ is preparing a Series A of around €12 million for early 2027. SeaO₂ has already pre-sold carbon-removal credits to early buyers, including Klarna, with delivery set for once operations begin. See Source7.
Mythos AI (PortXL ’23) announced a strategic collaboration with ANELLO Photonics to advance resilient navigation for maritime autonomy. The collaboration is focused on enabling plug-and-play, GPS-denied navigation capabilities for next-generation maritime platforms. See Source8.
Lobster Robotics (PortXL ’23) signed a Letter of Intent (LOI) with Blue Ecology Contractors to strengthen and expand their collaboration on offshore ecological monitoring activities. By combining the ecological monitoring and operational expertise of Blue Ecology Contractors with the state-of-art autonomous underwater technology of Lobster Robotics, the parties aim to offer most efficient and innovative solutions for offshore ecological research and monitoring campaigns. See Source9.
Carbonblue (PortXL ’24) launched a 20kg/day pilot plant for making lime sustainably from industrial waste. Their process dramatically reduces CO₂ emissions because it doesn’t involve fuel combustion, and utilizes abundant, low-carbonate industrial waste, as source material. A demonstration plant of 1mt/day is to be constructed later in 2026. See Source10.
GT Wings (PortXL ’23) announces strategic manufacturing partnership with Zunsion Technology for their Airwing production. The agreement creates a framework for industrial scale production of AirWing™ units in China, combining GT Wings’ wind propulsion technology expertise with Zunsion’s automation manufacturing capabilities. See Source11.
InnoTractor (PortXL ’20) developed PortGuard, in close collaboration with the Port of Rotterdam, and together with DronePort Rotterdam, Avanade, S2IX and Digidentity. PortGuard is a federated data space designed to enable Strategic Asset Intelligence in a world shaped by geopolitics, growing digital dependency and the increasing need for trusted collaboration. See Source12.
Excess Materials Exchange (PortXL ’24) is part of the core task force of the Circularity in Practice initiative, inspired by HRH Charles III of the United Kingdom and supported by the British Chambers of Commerce. See Source13.
Seaqualize (PortXL ’21) shared statistics about their role in the completed Vineyard Wind 1 project off the coast of Massachusetts, USA. They reported 99.6% uptime, among other impressive stats. Bravo! See Source14.
