Dr Ian Mabbett talks about SUNRISE, a project which aims to develop new materials for energy generation, storage and use that are integrated into buildings. The project takes ideas from labs into production, ideally locally where needed, then produces buildings that act as energy hubs across India, where 300 million people lack reliable 24/7 power. The work impacts on many of the UN’s Sustainable Development Goals, including affordable and clean energy, clean water and sanitation; and responsible consumption and production.
