Hydrogen from Biomass as an energy carrier has generated increasing interest in recent years. The solar energy industry is continuously looking for ways to store solar energy to be able to generate a better overlap between peak energy production and peak energy usage and to address the demand for transport fuels. Large paraboloidal dish solar concentrators are able to generate temperatures in excess of 1000°C and drive thermochemical reactions that can operate at such temperatures. ANU has commenced the investigation of supercritical water gasification of biomass for application with dish concentrators. The hydrogen produced presents a suitable energy storage solution in connection with solar thermal applications. Additionally, up to 30% of the energy stored in the product gas would come from the sun while in conventional approaches the equivalent of 30% of the product gas would have to be burned to provide the energy driving the reaction. One of the main objectives of this project is to study the reaction behaviour of the supercritical water gasification process in conditions with a simulated 'unreliable' energy source such as the sun. This paper describes a range of biomass sources and possibilities for application and presents a setup for investigation of the supercritical water gasification process in connection with solar thermal energy input.
