In order to meet its 2050 climate goals, the nation will have to reduce the amount of natural gas used for heating, however the electricity system will not be able to cope unless thermal storage technology is improved, Bloomberg reports.
То reduce its greenhouse gas emissions from the heating sector is “one of the toughest challenges the country faces in its low-carbon transition,” according to a report published Friday by the U.K. Energy Research Centre, a body that advises the public and private sector on sustainable energy.
The U.K. is heavily dependent on gas, since it comprises about two thirds of the domestic energy demand. The main issues stem from the fact that when the weather’s cold, the gas system handles a morning surge in demand by drawing on fuel stored in pipelines overnight, since gas pipelines have a dual purpose function. At the present, the electricity system can not do the same due to a lack of large-scale storage options.
Transferring demand for heating from the gas network to the electricity system would be a “significant challenge” in cold weather, UKERC said in the report published Friday.
UKERC analysis of local gas demand during coldest days of winter 2017-18 shows a very fast ramp up in demand from 05:00. until 08:00 when heating consumption surged by more than 100 gigawatts. That happened on 25 percent of days during the heating season last winter. Meeting that demand would be a huge leap for the power system, where peak supply only reached 53 gigawatts last winter.
