Energy efficiency in our operations
One of the metrics we use to measure our performance is energy intensity: the amount of energy consumed for every unit of output.
The refinery energy intensity index decreased from 96.9 in 2021 to 95.6 in 2022, in part due to higher utilisation rates, notably at the Shell Energy and Chemicals Park Singapore and Norco refinery in the USA.
Chemical steam cracker energy intensity in 2022 was 19.3 gigajoules per tonne (GJ/tonne) of high-value chemical (HVC) production, up from 18.1 GJ/tonne HVC in 2021. The increase was in part due to economic under-utilisation and less demand across our sites.
In 2022, the overall energy intensity for the production of oil and gas in our Upstream and Integrated Gas businesses (excluding liquefied natural gas and gas-to-liquids) increased from 1.14 in 2021 to 1.19.
