This one is easy, no - there is no need to change or upgrade your boiler to use renewable gases. Renewable gases (i.e. BioLPG and rDME) are known as ‘drop-in fuels’ which means you can use them in the same boiler and LPG storage tank you currently have. Made from a diverse mix of biological feedstocks and processes, they are chemically indistinct from fossil LPG, which means no retrofit costs, and an easy switch for people to make. They can even be blended with fossil LPG which sets them apart from other biofuel solutions, which cannot be blended with their conventional counterparts and require new infrastructure.
So whilst LPG is already a lower carbon energy source, BioLPG and rDME take this one step further offering up to 90% carbon emissions reductions and carrying the same low NOx, SOx and Particulate Matter. For more information, read more about a green future with renewable gases.
