The trade body OFTEC has secured publication of a new Publicly Available Specification (PAS 5420) to assure the sustainability of renewable liquid fuels such as Hydrotreated Vegetable Oil (HVO) as part of its commitment to offer low carbon heating solutions for off-gas grid buildings.
The specification sets out:
- That currently available renewable liquid fuels for use in fixed combustion applications for heating, hot water and cooking must be wholly derived from waste sources, such as used cooking oil, to ensure sustainability and decarbonisation of the liquid fuel heat sector with bio-liquids which do not impact land use or contain polluting fossil fuels.
- Audit requirements to maintain sustainability and decarbonisation via liquid fuels going forward, and;
- the process for next generation renewable liquid fuels to be evaluated for suitability for fixed combustion applications.
The publication by the British Standards Institution (BSI) follows an extensive review process by industry specialists alongside a public consultation. It replaces the existing voluntary industry standard BLPS 25 which OFTEC had previous published. Waste derived HVO is already recognised in the Standard Assessment Procedure (SAP 10.2) for compliance with building regulations, but this new specification provides the means and mechanisms to assure that only sustainable liquid fuels are used in the heat market.
The announcement comes as OFTEC calls on the government to adopt a technology neutral approach to off-grid decarbonisation which recognises renewable liquid fuels. OFTEC argues that harder to treat rural off gas grid oil properties would otherwise face unaffordable high costs and disruption to switch away from liquid fuel systems and that end users should have the option of using HVO via a more affordable non-disruptive conversion, which itself immediately reduces emissions by 88%.
Around 150 oil heated properties across the UK have already been converted to HVO as part of an industry demonstration project which has been running for over two years. OFTEC’s registered technicians are already skilled, with the fuel and infrastructure already existing, to be able to scale up decarbonisation of the liquid fuel heat sector.
