To ask the Scottish Government what research it has commissioned on converting gas boilers to run on alternative fuels.
In February 2022 we published research commissioned through the ClimateXChange (CxC) into direct, point-of-use greenhouse gas (GHG) emissions associated with zero carbon heating technologies, including hybrid boilers ( Direct greenhouse gas emissions from low and zero carbon heating systems (ed.ac.uk) ).
In May 2021 we published an evidence review, commissioned through the CxC, of all aspects of the use of hydrogen to heat buildings ( Evidence review for hydrogen for heat in buildings (climatexchange.org.uk) ), including converting gas boilers to run on hydrogen.
We will continue to monitor the growing body of research commissioned by other bodies and factor that in to our own decisions concerning further studies.
