Balanced Energy Networks

A working demonstration at London South Bank University will physically connect heating, cooling, electricity, and carbon capture into a single, cost-minimising network. This project tackles the "energy trilemma"—the challenge of keeping energy supplies secure, affordable, and low-carbon all at once. Currently, these systems operate largely in isolation, wasting energy when demand is low and struggling to meet peaks. The team will build an inter-seasonal thermal storage system that stores heat from summer for use in winter, and a bi-directional electricity network that can both send and receive power. Crucially, they will attach a device that generates electricity while simultaneously removing carbon dioxide from the air, making the whole system carbon neutral. If successful, this integrated approach could reshape how urban energy grids are designed. Instead of separate networks for heat, power, and emissions, future infrastructure could balance all three in real time, cutting costs and carbon simultaneously. The demonstration at a university campus provides a testbed that could be scaled to hospitals, business parks, or entire city districts. The project does not aim to discover new fundamental science—it is an engineering demonstration of how existing technologies can be combined into a practical, working system.
