Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what analysis his Department has undertaken of the potential impacts of co-locating WECCS (waste-energy carbon capture and storage) with EfW (energy-from-waste) plants on regional energy systems and grid infrastructure, including any potential to reduce the need for new grid connections.

Carbon capture, usage and storage (CCUS) is fundamental to the deep decarbonisation of industries such as EfW. CCUS is the only net zero compliant technology for many types of plants in the residual waste management sector.

The residential waste sector also has a high percentage of biogenic CO2, which if captured have the potential to create greenhouse gas removals.

CCUS technology requires energy to power the facility, and therefore the energy balance of an energy-from-waste (EfW) facility is expected to be impacted by the deployment of CCUS. These impacts will vary depending on the facility, notably whether the EfW facility is new or whether CCUS is being retrofitted on an existing site.
