ESG Today writes that the new system will replace the existing one, which uses natural gas in the process of manufacturing 700 million pints-worth of beer every year. Thus, electric heat pumps will be taking over the management of the heat used for beermaking. Some of the heat used in the process will be recovered and reused across various processes at the facility, with the aim to reduce the carbon footprint of the brewery.

Heineken officials say that the retrofitting will take until 2024 to complete and will help reduce 45% of the natural gas usage. The ultimate goal is for the Dutch beer company to achieve a net-zero carbon footprint by 2030 across its whole production range and for its value chain, "from barley to bar", by 2045.

Chelsey Wroe, Head of Sustainability at Heineken UK, said that "we need to act now if we are going to meet our 2030 net zero ambitions. Heat pumps are a key technology on our journey to decarbonizing our breweries and enable us to create a circular process with the excess heat that is created during the brewing process."
