How ending the Non-Domestic Renewable Heat Incentive will set back the UK’s net zero target

Luke Worrall, business development manager at biomass installation specialist NerG, explains why ending the Non-Domestic Renewable Heat Incentive will harm the UK’s efforts to reach net zero carbon emissions by 2050 unless policy gaps are addressed.

The Government’s planned end to the Non-Domestic Renewable Heat Incentive (NDRHI) this month will leave manufacturers without a financially viable green alternative to generate heat for many crucial industrial processes. This could force businesses to seek out cheaper, non-renewable sources of energy. 

On 11 March, 2020, in his budget speech, the Chancellor announced that the Government would be extending the Domestic RHI scheme into 2022, and that it would introduce a third allocation of Tariff Guarantees for the Non-Domestic RHI scheme — with the latter scheme ultimately coming to an end on 31 March 2021.

The subsequent closure consultation by the Government was met with mixed views from environmental groups. The Association for Renewable Energy & Clean Technology (REA) said that while the move to enable biomethane projects to claim payments from both the RHI and Department for Transport’s Renewable Transport Fuel Obligation (RTFO) scheme was welcome news, there were also concerns.

The association noted, “This consultation also brings into sharp relief that the Non-Domestic RHI will close in March with no comparable scheme or ambition in place to continue its success. As it stands, there will now be a very limited route to market for commercial heat decarbonisation projects and the pipeline for such developments is dramatically slowing. This is a policy gap that needs urgent attention if the UK is to achieve its 2050 net zero decarbonisation targets, which require the almost total decarbonisation of heat in all buildings.”

While the Chancellor’s most recent budget in March 2021 announced a £4 million biomass feedstock innovation programme, even this will not cater for the immediate need for industrial businesses to meet their heating needs.

According to the Department for Business, Energy and Industrial Strategy (BEIS), “Emissions from heat are the single biggest contributor to UK emissions. In 2016, they accounted for 37 per cent of UK emissions. The decarbonisation success seen in the power sector must now be replicated in heating if we are to meet our climate change commitments.”

The issue is that many industrial businesses rely on high-temperature heat for use in industrial processes, be it hot water, steam or thermal oil. Ground or air source heat pumps aren’t capable of delivering these temperatures, leaving biomass as the only viable renewable technology to support businesses in meeting this energy demand. This is essential for cooking, sterilising and processing many of the foods and products consumers use every day.

On average, biomass wood chips deliver over 92% carbon saving compared to high-temperature alternatives such as natural gas and gas-oil boilers. However, without the funding support provided by the NDRHI, many manufacturers will opt for cheaper, fossil-fuel powered alternatives.

According to Ofgem, “As of November 2020, the NDRHI has helped to produce a total of 54,701 GWh of renewable heat.”

Unfortunately, hydrogen is still a long way off and without Government incentives that help to justify the initial capital expenditure of a biomass system, many manufacturers will continue with traditional fossil-fuel powered gas or oil boilers.
