National Solar Energy Centre, Newcastle
Laboratories • High temp. materials • SEM • Optics
Heliostat and Receiver Performance
Solar Breakfast, July 2015 | Wes Stein
A CSIRO heliostat: • About 50kg of steel •5m2 of high reflectivity glass mirror •Actuators •Fancy electronics
Cost of “dumb” materials – about $50/m2
Thermal decomposition of carbonaceous or organic materials such as coal, natural gas or biomass to fuels. Because they are endothermic reactions, the fuel product has solar energy embodied in the chemical bonds.
CH4 + H2O = CO + 3H2 +206 kJ/mol
CH4 + CO2 = 2CO + 2H2 +247 kJ/mol
