In March 2011 the Government published its policy for the non-domestic Renewable Heat Incentive (RHI), including the intention to introduce air quality emission limits for biomass boilers (including CHP) that participate in the scheme. Proposed limits were first published for consultation in 2010. These limits were confirmed with the maximum permitted emissions being 30 grams per gigajoule (g/GJ) net heat input for particulate matter and 150g/GJ for NOx.
To be eligible for both the domestic and non-domestic schemes, biomass products must comply with emissions limits as outlined above. Evidence of compliance must be in the form of a vaild emissions certificate. Alternatively, for the non-domestic RHI, an environmental permit for the site is allowed.
A dedicated website of products that are covered by RHI emissions certificates is now available at rhieclist.org.uk. The website is administered by HETAS. Contact HETAS for further guidance on Air Quality Requirements and EC-Listing on firstname.lastname@example.org or call 01684 278170.
Ofgem, the scheme administrator for both the domestic and non-domestic RHI has produced a template emissions certiifcate which can be used for both schemes, but will be assessed separately against the requirement of each scheme. These templates are available at rhieclist.org.uk/apply-for-listing. Alternatively, contact HETAS for further guidance.
If your product is not already covered by a vaild RHI emissions certifcate you should:
- View the template certificate and read the guidance – rhieclist.org.uk/apply-for-listing
- Arrange for an authorised testing laboratory to perform the required assessment of your product
- Ensure the testing laboratory completes the template emissions certificate in accordance with the guidance set out on it
With the domestic RHI due to be launched over the coming week the Department of Energy & Climate Change, Ofgem and HETAS are urging manufacturers to get their certificates sorted now. At present, only around 25 manufacturers have their appliances listed on the RHI EC website. Please contact HETAS for further guidance on Air Quality Requirements and EC-Listing on email@example.com or call 01684 278170.
