Allocated to $39 million for the department of energy (doe) solar photovoltaic application advance of supercritical carbon dioxide commercial solar-thermal power generation technology

Solar photovoltaic (pv) net news: on January 5, the U. S. department of energy ( DOE） Allocated to 1. $25. 5 billion cash advance innovative solar project development, China solar power network, including the solar-thermal power generation related r&d project from about $44 million. DOE in recent years, as the project continues to advance, in support of supercritical carbon dioxide constantly upping the solar-thermal power generation related technology research and development, China solar energy network, has made significant progress. DOE expressed, the goal of this project is to accelerate the supercritical carbon dioxide brayton cycle technology commercialization, and utility operators and light power developers provide operational experience. Since this century, the heating system in energy, pavilions mouth power station under the condition of environmental problem, supercritical carbon dioxide brayton cycle technology has drawn wide attention. It is worth mentioning that allocated solar-thermal power generation projects in the capital of the vast majority of ( $39 million) Will be used to promote the supercritical carbon dioxide brayton cycle technology commercialization, in order to help us achieve the goal of solar-thermal power generation cost as soon as possible. Among them, the EPC project owner units is given priority to with soe/state, this also reflected from the side, in the project bidding and parity, solar panels, state-owned enterprises have become the absolute main force. SCO2 through customized high pressure test loop test, solar controller is proved to satisfy all the turbines mechanical performance index.

just in March 2019, DOE has funding to support the advanced high strength carbon dioxide heat exchanger creep and fatigue properties of nickel alloy sheet ', 'apply to power cycle and energy storage system based on carbon dioxide, a senior compressor', 'is suitable for the advanced thermal circulation of low-cost short/long term thermal chemistry and chemical energy storage', 'reduce the supercritical carbon dioxide and heat power generation system close to the end of the cost of capital type hot isostatic pressing mechanism made way', 'used in CSP turbine machinery new self-lubricating efficient vertical arrangement of brush seal of carbon nanotube array', such as a number of supercritical carbon dioxide related technology research and development projects. In this aspect is particularly active in the United States, the U. S. department of energy ( DOE） In 2011 began to implement in the field of solar energy application & other; Sunshot” Research plan, the project of the supercritical carbon dioxide brayton cycle system research and development project main body of the project for the project research and development of 10 mw supercritical carbon dioxide generators and test, by the American sandia (solar panels, Sandia） National laboratory - Nuclear energy system laboratory ( NESL） Bear the relevant experimental study. This paper statistics the September to today issued a total of 2. 85 gw pv power plant EPC and 1. 9 gw component bid opening information!

the article content is for reference only. According to the test data, compared with the traditional thermal power plant steam turbine - 35% 40% thermal efficiency, the use of supercritical carbon dioxide solar-thermal power generation technology of steam turbine thermal efficiency can reach 50%. In the planning of the propulsion technology maturity and application, the U. S. department of energy ( DOE） Has to carry out the implementation of the 10 mw demonstration project is discussed when the market application and advance the schedule. Specifically, photovoltaic modules in photovoltaic component application widely in development of 410 mw, 603 mw nuclear, guangzhou energy saving 220 mw, 345 mw, jin can group the people vote for 200 mw, 190 mw hubei energy group, huaneng 180 mw, the deduction of $39 million will be used in one or two research and development projects, construction and demonstrate supercritical carbon dioxide brayton cycle technology, relevant systems should be implement in 550 & deg; & C to 630 deg. C between thermal energy storage. By 2030, according to the goal of DOE, solar controller contains 12 hours the thermal storage system of thermal power generation cost will reduce to $50 / mw ( 5 cents per kWh, solar panels, or about RMB 0. 35 yuan/kWh) , heating system and promote the supercritical carbon dioxide brayton cycle technology commercialization as soon as possible is one of important measures to realize this goal. The plan is mainly divided into the following process: in April 2019, by the southwest research institute ( SwRI) GE GE joint design and manufacturing, with the United States is the world's highest operating temperature of supercritical carbon dioxide ( sCO2) The turbine was tested. 2020 ~ 2025, the implementation of application in the field of thermal power generation, pavilions mouth power station within 10 ~ 100 mw power level efficiency over steam turbine; Five years before the test, and SETO SwRI team partners design multistage axial-flow sCO2 steam turbine expander, thermal storage air conditioning GE meanings for the design of the turbine rotor has made a significant contribution.
