Is there a role for CHP in the Net Zero economy?

With de-carbonisation of the UK’s grid electricity supply can Combined Heat and Power (CHP) still have a role in moving towards a Net Zero economy? 

With increasing electricity prices and static, or even reducing gas prices there can be significant economic benefits from installing a new reciprocating engine CHP plant on a site that has a suitable and consistent heat load.  However, the carbon reduction benefits may now be less clear cut.

Many existing CHP units are reaching the end of their planned or contracted service life or may need investment to comply with tighter NOx emission limits under the Medium Combustion Plant Directive. The economic benefits of re-lifing or replacing existing CHP plant can be very attractive, particularly if it provides an opportunity for efficiency improvements. But what would be the impact be on commitments to reduce carbon emissions?
