Economy Minister Conor Murphy has launched a Call for Evidence to explore the potential use of biofuels as an alternative to home heating oil and fossil-based LPG. Biofuels, specifically Hydrotreated Vegetable Oil (HVO) and Bio-Liquefied Petroleum Gas (Bio-LPG), can be used as an alternative heat source to fossil fuels. Industry research and analysis indicate biofuels are the most likely renewable heat alternative for homes and businesses that cannot be heated by heat pumps, the gas grid or heating networks.
