Solar-Driven Supercritical CO2 Brayton Cycle
Sector: Commercial • Location: Australia
Source: Australian Renewable Energy Agency (ARENA)
Building on CSIRO’s solar air turbine technology, this project examined ways to reduce the cost of solar energy to less than 10 cents per kilowatt hour (c/kWh) which would make solar energy cost competitive with existing power stations.Key resultsThe conditions under which Supercritical CO2 (sCO2 ) is required to operate within the power cycle result in short life spans for traditional seal materi

Description
Description | Building on CSIRO’s solar air turbine technology, this project examined ways to reduce the cost of solar energy to less than 10 cents per kilowatt hour (c/kWh) which would make solar energy cost competitive with existing power stations.Key resultsThe conditions under which Supercritical CO2 (sCO2 ) is required to operate within the power cycle result in short life spans for traditional seal materials. This was identified within the reciprocating pump seals and valve seats, which were observed to deteriorate at an advanced rate. CSIRO continues to experiment with the sCO2 system and is working with manufacturers of pumps and developers of seal materials to better understand the behaviour and mechanisms of attack for sCO2 in the presence of carbon based seals materials. CSIRO is also investigating the configuration and layout of the seal with a mixture of materials to take advantage of specific properties of individual components and materials to combine and work to provide a long lasting seal. |
