Here’s how we calculate the figures for our green gasmills...
Carbon dioxide savings are calculated based on the maximum carbon intensity of biomethane required for RHI eligibility, which is 34.8gCO2/MJ.
This is considered against the carbon intensity of natural gas of 51.23gCO2/MJ (Defra GHG Conversion Factors 2015), giving a saving of 16.43g CO2/MJ.
It is worth noting that this represents a worst case scenario saving. The size of the proposed Green Gasmill enables even greater efficiency and the savings are likely to be significantly higher.
The number of households that could be supplied by the proposed development is calculated based on Ofgem's typical domestic gas consumption of 12,500kWh per year, which is an average across the UK.
*Variances in households numbers can result from using local consumption rates or different feedstock combinations.
As more and more people understand what's at stake, they become a part of the solution, and share both in the challenges and opportunities presented by the climate crises.
