Eden Project biomass energy crop feasibility study

Abstract

A biomass feasibility study has been completed for The Eden Project in Cornwall, England. The aims of this study are to investigate the feasibility of using energy crops as an alternative energy source, replacing the need for fossil-fuelled energy systems whilst providing assistance to the local agricultural economy. The supply of Short Rotation Coppice, miscanthus and local forestry wastes are shown to be viable for the scheme. Each of these sources could be grown or sourced locally, providing economic, practical and environmental benefits to Eden and the local community over the long term. The most appropriate energy system is a 300 kW wood-chip boiler providing the base load site hot water requirement all year round. The development of a mixed biomass fuel supply, based at first on local forestry wastes, with energy crops input over time once they have been established, is recommended. This provides support for, the development of a quality wood fuel supply infrastructure and a secure supply route for locally grown energy crops. However, there are a number of issues with integrating the biomass boiler within the existing site that still need to be overcome.
