Grid to cut carbon emissions 27 July 2020

UK electricity grid’s carbon emissions could turn negative by 2033, says National Grid (via The Guardian)

Carbon emissions from Britain’s electricity system could turn negative by as early as 2033 if the UK uses carbon capture technology alongside more renewable energy to reach its climate targets, according to a report from National Grid.

The electricity network operator on Monday set out its vision for an “emissions negative” grid that would include 30m electric vehicles on UK roads, and 8m heat pumps used to replace gas boilers in energy-efficient homes.

In National Grid’s most progressive vision for Britain’s pathway towards its 2050 climate targets it claims that net carbon emissions from the electricity sector could turn negative within 13 years by using carbon capture technology alongside bioenergy sources.

Mark Herring, the head of strategy at National Grid ESO, said three of the report’s four most-credible pathwaysto a net-zero economy by 2050 meant relying heavily on low-carbon electricity.

National Grid expects a boom in renewable energy projects, including at least 3GW of new windpower capacity and 1.4GW of solar generation every year from now until 2050, alongside a widespread rollout of electric vehicles, which will effectively act as smart-charging “batteries” to help balance the electricity grid.

It also expects a revolution in consumer energy use, including significantly better energy efficiency and the end of gas boilers. Instead, millions of homes will consume less than a third of the energy used today, and will rely on heat pumps fitted with thermal “heat batteries”.
