Cleaner engines

We’re deploying new hybrid generators to lower carbon emissions as part of our industry leading Green Action Plan. 

Project-on-a-Page summary

Project data

Start date: 01/10/2020
End date: 31/10/2022
Budget: £433,000

On rare occasions we deploy back up generators to keep power supplies 99.99% reliable for millions of customers in London, the South East and East of England. We do this to keep our customers safe and warm, especially during periods of bad weather. Cleaner engines is aiming to understand how we could deploy hybrid generators which produce fewer carbon emissions than those currently in use.

We’re investigating several different types of hybrid generators, including some which use a biofuel made from hydrotreated vegetable oil (HVO). In the project we’ll work with a variety of potential suppliers to design and demonstrate different types of hybrid generator. We’re testing numerous different versions to make sure we select the one which provides the best performance, efficiency, reliability and emissions reduction.

We’re designing and testing brand new types of generators that have never been deployed before. The project will trial several innovative new fuels, including a biofuel made from vegetable oil and a fuel made from glycerine which was developed for Formula E race cars.

The project will help us understand which type of hybrid generator will be best for our customers and produce the greatest reduction in emissions. We will also learn how the new types of fuels could be stored and used in practice. Overall, the project will also inform our industry leading Green Action Plan and help us lower our carbon footprint.
