24 ЭНЕРГОРЕСУРСОСБЕРЕЖЕНИЕ И ЭНЕРГОЭФФЕКТИВНОСТЬ Solar towers with thermal storage for integrated solar combined cycle plants PhD, University of Technology in Sydney, Australia Group-Mechanical Engineering leader, Laing O’Rourke, Australia ERK Eckrohrkessel GmbH, Berlin, Germany Institute for Sustainable Futures at the University of Technology, Sydney, Australia Hybridization is a low-cost approach to implement power plants worldwide. <...> Generally, integrated solar combined cycle power stations combine the energy harvested from solar radiation with another fuel to cut fuel costs and environmental impact. <...> Several operating plants would qualify for conversion into integrated solar combined cycle ones, and plants in the planning stage should consider this option. <...> The example described below investigates the conversion of a Western Australia power plant into an integrated solar combined cycle plant using a solar tower and thermal storage. <...> Current global efforts to reduce CO2 emissions aim to incentivize utility and industrial plant operators to build renewable and low-carbon intensity generation assets. <...> Renewable energy technologies, such as concentrated solar power (CSP), progressed significantly in the past decade in regard to efficiency and cost. <...> However, when making investment decisions without including external costs for fossil fuels or government incentives for renewable electricity, the current economic climate favors natural gas-fired open cycle gas turbines (OCGT) and combined cycle gas turbines (CCGT) plants when compared to concentrated solar power installations. <...> To lower the specific investment of CSP systems and prepare for rising natural gas prices in the future, existing OCGT and CCGT plants could be retrofitted and new plants designed with a CSP component. <...> This would create environmental benefits, such as carbon intensity reduction, as well as economic benefits, such as lower investment CSP installations and renewable energy certificates. <...> Of particular interest is the retrofit of solar towers to reduce cost and allow independent operation of CCGT and CSP component. <...> Current ISCC plants use parabolic trough systems with thermal oil to boost the steam output of the CCGT’s heat recovery steam generator (HRSG). <...> Typically, daytime electricity prices are significantly higher <...>
