- Most decarbonization efforts in the maritime sector are currently focusing on updating the fleet with new ships and the transition to green fuels, which leave the shipowners with few options to achieve the emission objectives
- In the United Kingdom Alisha Fredriksson (Suede/ /Canada) and Roujia Wen (China) Founded Seabound, a startup that builds a retrofitable carbon capture system that imprison the Co₂ of the ship’s exhausts
- The team is among the ten tops of the innovators of the Young Inventors Prize, which will be awarded by the European Patent Office (EPO) June 18, 2025
MUNICH,, May 8, 2025 / Prnewswire / – Depending on the Organization for economic cooperation and developmentGlobal navigation is a major contributor to emissions, releasing more than 800 million tonnes of CO₂ each year. THE European Commission Also reports that EU maritime transport exceeded 124 million tonnes in 2021, representing 3 to 4% of total block emissions. While alternative fuels and new ships conceptions offer long -term solutions, most existing ships do not have an achievable renovation option to reduce CO₂ emissions to achieve emission objectives. Alisha Fredriksson (30) and Roujia Wen (29) co-founded Selo Carbon capture system To help shipowners cut emissions without replacing their fleets. By capturing the CO₂ in solid limestone rather than storing it in the form of liquid or gas, the Seabound solution makes unloading and the treatment simple, eliminating the need for CO₂ equipment on a complex board or a specialized portable infrastructure. Their invention earned them a place among the ten world innovators, known as Tomorrow ShapersFor the price of young inventors 2025, selected from more than 450 candidates by an independent jury.
A modular solution for maritime decarbonization
Most carbon capture systems require costly and high energy intensity systems to compress and store CO₂ on board, but the compact system and based on Seabound containers Capture the CO₂ directly from the exhaust of a ship and binds it with a lime sorbant to form solid limestone dumplings. This removes the need for co₂ under pressure reservoirs and also rationalizes logistics on the edge because limestone can be discharged in shipping containers in the form of ordinary cargo.
The sea system is designed to provide flexibility to shipowners – modular units can be extended to match a ship’s emissions. The system works effectively, using exhaust heat to maintain the process while requiring only minimal energy for sensors and valves. Limestone can then be sold to be used as a building materials or the nearby post-proxy port to release CO₂, which can be used in other products (for example, the production of electronic fuels) or for sequestration, with recycled lime for future capture. Technology also removes sulfur emissions, making it a dual -use purifier that helps ships reduce pollution without costly replacement of the fleet.
Concepts with sea tests
Fredriksson and Wen met at the University and co-founded Seabound in 2021, motivated by the need for a practical solution to sea programs. Fredriksson had worked with maritime e-fuel, where the captured co₂ was necessary as raw material but was lacking in supplies. Wen, with training in applied mathematics and AI, helped Design a modular carbon capture system that could be easily installed on existing ships. “”We line the CO₂ in solid form using calcium -based materials, which makes storage as simple as the transport of goods. No specialized equipment, no extreme conditions, just a stable and scalable way to reduce sea emissions, ” explained Wen.
They itered through several work prototypes in their London Workshop before switching to large -scale tests at sea. According to Seabound, their system was tested on a commercial cargo and managed to capture the CO₂ at 78% efficiency and 90% efficiency. “”Shipping is one of the last sectors to be decarbonized, because existing solutions are neither effective nor economically viable. Carbon capture was an emerging technology in other sectors, so we started to think about ways to make it work and we decided to take up the challenge together,“Addition of Fredriksson.
The price of young inventors celebrates global innovators 30 and under the use of technology to meet the global challenges posed by the United Nations Sustainable Development Goals (SDGs). The invention of Fredriksson and Wen supports the ODD 13 (climate action) by providing a practical and scalable solution to reduce carbon emissions in the maritime industry.
The prices of the 2025 edition will be announced during a ceremony live Since Iceland June 18, 2025.

About the price of young inventors
Intended for individuals aged 30 and under, the price of young inventors highlights the transformative power of young people focused on young people and recognizes remarkable young people paving the way for a more sustainable future. Created in 2022, trophies were the first time during the European Inventor Prize ceremony. From 2025, the price will increase equipment with its own dedicated event, held separately from the price. Among the 10 Shapers of tomorrow selected for each edition, three will receive a special prize: world manufacturers, community healers and nature guards. In addition, a winner of the people’s choice, voted by the online public, will be revealed. Each Shaper of tomorrow will receive EUR 5 000, the three special winners will each receive an additional EUR 15 000. The winner of the people’s choice will receive a EUR 5 000. Learn more On the criteria of eligibility and selection of the price of young inventors.
About EPO
With 6,300 staff members, the European Patent Office (EPO) is one of the largest public service institutions to Europe. Whose head office Munich with offices in Berlin,, Brussels,, Hague And ViennaThe EPO was founded in order to strengthen cooperation on patents Europe. Thanks to the centralized EPO patent procedure, inventors can obtain high -quality patent protection in up to 46 countries, covering a market of some 700 million people.
