Tom Baxter examines the challenges and opportunities of electrifying process heating
THE chemicals sector is a significant energy user and consequently a direct and indirect contributor to the UK’s GHG footprint (
see Table 1)
1.
The indirect footprint occurs as a result of the emissions from production of gas or electricity which occur outside of the plant boundary. As is evident from the table, energy use in the chemicals sector is dominated by natural gas and electricity – natural gas being mainly used for process heating through combustion and electricity for electric drives.
Both natural gas and electricity usage for heat and power in the chemical industry will have to be addressed for the UK’s pathway to net zero by 2050. Whilst electricity can be readily made net zero through the use of renewables, the replacement for unabated combustion of natural gas is not so straightforward.
