Aalborg CSP A/S to supply steam generation system for Chinese concentrated solar power plant

Aalborg CSP A/S in collaboration with Jiangsu Livo New Energy Technology Co., Ltd is to supply a steam generation system for the 50 MW Shenzen Jinfan concentrated solar power (CSP) plant in China.
Aalborg CSP A/S to supply steam generation system for Chinese concentrated solar power plant

The Shenzen Jinfan concentrated solar power (CSP) is among the first 20 demonstration plants that China intends to build by the end of 2018. It is a flagship project which has an exceptionally long 15-hours energy storage capability. It is also a good example of how European design combined with local manufacturing can secure on-demand and cost-competitive renewable power generation in China.

The project forms part of China’s five-year plan aiming to change the landscape of large-scale electricity production. In the first batch, China awarded 20 demonstration plants to produce 1 GW power with RMB1.15/kWh feed-in-tariffs (FiT) if completed before the end of 2018. To reach low price levels, solar projects with large energy storage capabilities have been announced, among which the 50 MW Shenzen Jinfan CSP plant has been proven to be one of the most efficient due to its exceptionally long, 15-hours energy storage capability. This enables the facility to supply power for 24-hours straight in Aksa County.

Aalborg CSP together with its local manufacturing partner, Livo New Energy Technology have been selected to supply the boiler equipment capable of securing uninterrupted conversion of solar heat to superheated steam at 136 bara and 538°C. The SGS4 steam generation system intended for the Shenzen Jinfan project was specifically designed to meet emerging market expectations for cost-efficient and reliable electricity production when using molten salt - an essential criteria that developing markets, such as China, are demanding to meet low price levels.

“Molten salt is an efficient heat transfer media but it is also known to place high demands on component reliability and project costs" said Jens Taggart Pell, Vice President of Technical Sales, CSP Power Plant division of Aalborg CSP. "With our local strategic partner, we are able to deliver a proven European technology that can also compete with local prices, thereby fostering technology deployment in China. We are pleased to share our technology know-how and extensive project experience with the Chinese CSP market and look forward to helping more solar plants achieve their energy production targets”.

The SGS4 steam generator technology adds to award-winning operational features utilised by the plant, including natural circulation, leakage-free design, and fast-start-up time. These operational benefits will deliver significant savings in terms of component CAPEX and OPEX as the plant will be able to produce more energy compared to an ordinary heat exchanger and reduce the need for certain auxiliary components, such as circulation pumps and different drain valves.

Besides the steam producing equipment, Aalborg CSP’s scope of supply also includes instruments, valves, heat tracing for the pressure vessels and interconnecting piping. Production has already commenced in China and delivery of components is expected to be complete by next summer, so that the facility can supply renewable power to the grid before the end of 2018.
