Impacts of Investment Cost, Energy Prices and Carbon Tax on Promoting the Combined Cooling, Heating and Power (CCHP) System of an Amusement Park Resort in Shanghai

Abstract

Poor economic performance has limited the diffusion of the combined cooling, heating, and power (CCHP) system. Various factors influence the economic performance of the CCHP system. To analyze the impacts of these different factors and promote the CCHP system, this study evaluated its comprehensive performance through a multi-criteria method, using an amusement park resort in Shanghai as a research case. First, three CCHP systems with different penetration rates were presented and simulated in a transient simulation model for comparison. The economic and environmental performance of these different penetration CCHP systems were evaluated based on the dynamic payback period and carbon dioxide emissions. The impacts of investment cost, energy prices, investment subsidy and a carbon tax on the economic performance of the three systems were discussed, and a sensitivity analysis was used to compare these factors. The results show that the current subsidy can reduce the economic gap between the CCHP system and the conventional system, but it still needs to be increased by 1.71 times to achieve market competitiveness of the CCHP system with 100% penetration under the current investment cost and energy prices. In addition, the introduction of a carbon tax could accelerate the promotion of the CCHP system. When the carbon tax reaches 25 $/ton, the CCHP system becomes the best choice of energy supply system.

“…The green shoot scenarios were exempted. In their estimations, energy demand will rise more steadily in all scenarios with time until 2030 and 2035 levels, which were presumed higher [41,42].…”

Potential Analysis and Optimization of Combined Cooling, Heating, and Power (CCHP) Systems for Eco-Campus Design Based on Comprehensive Performance Assessment

“…Yan et al (Yan et al, 2016) and Zheng et al (Zheng et al, 2018) analyzed the sensitivity of electricity price and natural gas price and explained the changes in important criteria at different prices. Zhang et al (Zhang et al, 2020) analyzed the performance of the CCHP system and deduced that it can be improved by changing the electricity price, natural gas price, investment subsidy, and carbon tax. Delgado et al (Delgado et al, 2017) analyzed the sensitivity of interest rate, heat export, and energy price escalation rates to address the behavior of the results due to changes in the economic context.…”
