Become the engineer who connects clean tech and energy systems
Energy systems are no longer defined by a single technology. Renewable generation, storage, electricity and heat, buildings, transport, markets and policy increasingly have to work together. Engineers need to understand how individual technologies perform and how decisions in one part of the system affect the rest.
The Master’s in Sustainable Energy Systems prepares you to work across those connections. In Year 1, you build a shared foundation in energy technologies, systems, economics, policy and sustainability. In Year 2, you choose one of seven specialisation tracks, from combined energy systems and Energy-to-X to offshore, digital and circular energy systems.
