Supply is set to rise to over 35 million litres in bulk and close to one million litres in cylinders within the coming year, taking renewable liquid gases to a combined market share of well over 3%.

Figures show this growth is down to industry investment, with a reported £1 billion of actual and planned investment this decade, £415 million of which is planned up to 2030. Around £75 million is specifically being invested in renewable liquid gases over the next year.

George Webb, chief executive of Liquid Gas UK, said: “Renewable liquid gases like bioLPG are playing a practical role in decarbonising heat, particularly for rural and off-grid homes and businesses which aren’t suitable for electrification.

“Supplying 25 million litres of renewable liquid gases to customers is a real milestone, and the fact this is expected to rise by 40% over the next 12 months shows the pace of change and determination to deliver a futureproof fuel across our sector.”

The biggest industries of growth identified across the sector are domestic heating, agriculture, leisure and industrial processing.

Industrial demand is a significant driver of this growth, reflecting the role LPG and renewable liquid gases can play in supporting UK manufacturing and processing industries that rely on high-temperature heat, such as glass manufacturing.

For the four million UK homes off the gas grid, renewable liquid gases offer a seamless, drop-in alternative to electric technologies, integrating into existing LPG systems.

“The census highlights the opportunity for a broader energy mix to contribute towards the decarbonisation of heat,” said Mr Webb.

“Thanks to industry investment, renewable liquid gases are already being supplied into the UK market.

“Looking forward, with the right long-term policy framework in place, we can accelerate supply, unlock further investment, and help deliver a fair transition to Net Zero for those in rural and off-grid areas,” he added.
