Energy as a Service to lower costs for renewable tech

Boxergy will offer customers ‘energy as a service’, lowering costs and making it easy for them to switch to greener technology. Their Hero product uses AI to build a smart platform that lets customers add to their existing renewables and connects them with others creating a virtual power plant that pays them to use energy.

Charge electric storage heating with renewable energy

Connected Response’s solution aims to transform the lives of households that have electric storage heating and hot water systems who commonly complain that they are too warm in the morning but cold in the evening. They do this by charging the systems with renewable energy, improving comfort and reducing bills – good for people and for the planet!

Turn electric water heaters into intelligent batteries

Plentify’s innovation, HotBot, transforms your electric water heater into an intelligent battery to slash your utility bills and reduce carbon emissions. HotBot automatically adjusts the heating schedule of your water heater to maximize the use of affordable renewable energy and lower time of use tariffs, while giving you full control of your water heater via its slick app! 

Use electricity to create zero emission boilers

Tepeo are developing a zero emission boiler that uses electricity instead of gas or oil and stores it as heat ready for when it is needed, much like a battery. Their tech does the clever stuff to ensure it is charging at the cleanest, greenest and cheapest times of the day whilst supporting renewable generation.

Make electrical heaters carbon neutral

Themo are on a mission to make electrical heaters carbon neutral via their smart thermostat that knows exactly when there is a lot of solar and wind electricity in the grid and it will choose to optimise your home heating cycles to those time periods. By using the Themo thermostats your house will be warm, but your carbon footprint will be zero!

Why are we focusing on heat?

At EDF, our mission is to help Britain achieve Net Zero and heating is one of the UK’s biggest sources of carbon emissions. In June 2019, the UK Government committed to a Net Zero carbon emissions target across the economy by 2050 and decarbonising heat is key to achieving this. The Department for Business, Energy and Industrial Strategy (BEIS) has recently set out proposals for the future of low carbon heat beyond 2021.

We want to explore what innovations are available now and collaborate with the best young companies innovating in this space and help them develop and grow, and help Britain achieve Net Zero.
