A hybrid wind-biomass system project being led by the UK's De Montfort University is a novel approach to designing a stand-alone system for local areas which does not need any form of storage, but which is wholly based on the use of renewable energies. The Joule III project aims to integrate three renewable forms of energy. A wind turbine is the primary source of power, but when winds are inadequate it is supplemented by an engine generator set fuelled either by biogas or a wood gasifier. The green credentials of the system are further enhanced by the engine generator set being a combined heat and power system and therefore of high efficiency, providing both electrical power and hot water. The project is not a simulation but is testing an actual installation on a university and farm complex where a range of demand profiles are to be simulated. Feedstock for the gasifier is supplied by short rotation coppice plantation on the farm.
