abstract |
Anaerobic digestion (AD) has the potential to support diversion of organic waste from
landfill and increase renewable energy production. However, diffusion of this technology
has been uneven, with countries such as Germany and Sweden taking the lead, but limited
diffusion in other countries such as the UK. In this context, this study explores
the financial viability of AD in the UK to offer reasons why it has not been more
widely used. This paper presents a model that calculates the Internal Rate of Return
(IRR) on a twenty year investment in a 30,000 tonnes per annum wet mesophilic AD plant
in the UK for the treatment of source separated organic waste, which is judged to
be a suitable technology for the UK climate. The model evaluates the financial significance
of the different alternative energy outputs from this AD plant and the resulting economic
subsidies paid for renewable energy. Results show that renewable electricity and renewable
heat sales supported by renewable electricity and renewable heat tariffs generates
the greatest IRR (31.26%). All other uses of biogas generate an IRR in excess of 15%,
and are judged to be a financially viable investment. Sensitivity analysis highlights
the financial significance of: economic incentive payments and a waste management
gate fee; and demonstrates that the fate of the digestate by-product is a source of
financial uncertainty for AD investors. |
