The Senergy project was developed to demonstrate a novel solar thermal collector system using polymer nanocomposites enhanced with carbon nanotubes. Led by Ulster University’s Centre for Sustainable Technologies, the project aimed to address the limitations of conventional solar water heaters in cold and windy climates, particularly in Northern Ireland. Senergy Innovations Ltd had previously conceptualised a low-cost, all-plastic solar collector design, and this project enabled the advancement of that concept toward commercial viability.
During the project, the design was reviewed with local plastics industry experts to assess manufacturing feasibility. Ulster University collaborated with Semple & McKillop Consulting Engineers to develop a simulation model of the collector array integrated into a domestic hot water system. Modelling indicated that a 9 m² array could supply approximately 25% of the annual hot water demand for a typical three-bedroom house in Belfast.
Second-generation prototypes were fabricated and tested in Ulster’s solar simulator laboratory. These prototypes resolved issues encountered in earlier designs, such as water leakage and fragility. Plans were made to install an outdoor demonstrator to validate the simulation model and showcase the technology to potential investors – helping Senergy to secure a significant award from Innovate UK to further develop the technology.
CASE was instrumental in enabling prototype development, upgrading testing facilities, and fostering collaboration between academia and industry. The project provided Senergy with a platform to progress its technology and engage stakeholders in the renewable heating sector.
