Connected Places Catapult is inviting applications for the Clean Transport Accelerator: Maritime, a six-month programme supporting small and medium-sized enterprises (SMEs) developing innovative solutions for the maritime sector.

The accelerator focuses on decarbonisation, future fuels, electrification and other technologies that support the sector’s transition to cleaner operations. It is seeking up to six SMEs with solutions at TRL 5–8. The programme is delivered in collaboration with a consortium of partners including Serco, Port of Tyne, Portsmouth International Port and the National Shipbuilding Office, with support from Maersk.

Participating SMEs will receive tailored commercial support based on a detailed business needs assessment. Support may include market analysis, value proposition development, pricing strategy, financial forecasting and communications guidance.

Successful applicants will also have the opportunity to apply for up to £30,000 in funding to deliver a four-month trial of their solution with a programme partner, benefiting from access to industry expertise, facilities and testing environments.

The Clean Transport Accelerator: Maritime builds on four years of success from the Catapult’s previous Maritime Accelerator programme, which has so far supported 29 SMEs and delivered 11 trials.

On 30 June, Connected Places Catapult will hold an application support webinar to give applicants the opportunity to find out more about the programme offering, challenges, application process, scoring criteria, and the assessment process. Register to attend the webinar here.

    • you must be UK-registered
    • you must have a solution which is technical readiness level (TRL) 5 – 8. This means that the solution has, at least, been tested or demonstrated in its intended environment and, at most, has been deployed as a first-of-a-kind commercial system
    • your solution must address at least one of the identified challenges
    • you already operate in the maritime sector, or are looking to bring your solution into maritime space from another sector
    • you must be willing to travel on occasion for face-to-face meetings such as the Welcome Day on the 29th of September
    • you must be available to actively participate in the programme activities between September 2026 and March 2027 inclusive
  • Challenge put forward by Serco

    How might we enable better insight into current fleet operations to solve future challenges related to emissions, predictive maintenance and/or duty cycles?​

    We are seeking innovative solutions that offer:

    • Management and filtering of the flow of data to improve relevance ​
    • Improved data insights & analysis on existing vessel operations & emissions​
    • Optimisation of duty cycles for reduced emissions​
    • Predictive maintenance of existing vessels​
    • Insights into future fleet operations, including but not limited to – retrofittable clean technologies or clean autonomy​
  • Challenge put forward by: Port of Tyne

    How might we enable accurate and consistent capture of scope 3 emissions from entry to exit, including enabling third parties to capture and share their data more easily in alignment with the port?

    We are seeking innovative solutions that offer:​

    • Accurate information capture or a framework for information capture from suppliers​
    • Inventory tracking & predictions on future emissions, which may be supported by AI or digital storage​
    • Digital tracking & integrated systems​
    • Better transparency and efficiency of scope 3 emissions tracking​
  • Challenge put forward by Portsmouth International Port

    How might we enable the use of excess clean energy to improve utilisation of shore power assets and strengthen the commercial case for ports, whilst increasing access to low-carbon energy for third parties?​

    We are seeking innovative solutions that offer:​

    • Aggregation and management of third-party demand (e.g. construction, events, temporary high-power use)​
    • Deployment and trial of portable hardware solutions (e.g. battery systems) that can be utilised, shared and/or relocated by third parties​
    • Integration of software to support management, compliance and commercial pathways for energy redistribution in ports ​
    • Future integration with wider systems​
  • Challenge put forward by National Shipbuilding Office

    How might we enable the use of decarbonisation technologies in vessel manufacturing and shipyard operations to reduce lifecycle emissions, lower energy demand, and deliver lower embodied carbon assets?​

    We are seeking innovative solutions that offer:​

    • Increasing use of low-carbon fuels or electricity to reduce reliance on fossil fuels in shipyard manufacturing​
    • Circular use of materials and/or energy within shipyard processes such as vessel building and repairs, or component manufacturing​
    • Optimisation of manufacturing processes to reduce energy demand​
    • Reduction of waste across shipyard operations​
    • Predictive maintenance of plant to improve efficiency and reduce energy use​
