Government and enterprise co-production of energy storage solutions

Do government subsidies increase total factor productivity of energy storage enterprises?

Based on panel data of Chinese 101 energy storage enterprises from 2007 to 2022, this paper examines the effectiveness of government subsidies in the energy storage industry from the perspective of total factor productivity (TFP). The results unveil that government subsidies significantly increase the TFP of ESEs.

Does Unified Energy Storage Co-deployment affect the economics of renewable generation?

The results show that the nationally unified energy storage co-deployment requirement, namely, 15% capacity ratio of renewable installation and 4 h duration, will negatively affect the economics of renewable generation, leading to an average cost increase in 15% and 21% for wind and photovoltaic generation, respectively.

How do government subsidies help energy storage enterprises?

Government subsidies alleviate the financial constraints of energy storage enterprises. Government subsidies promote R&D investment in energy storage enterprises. Differentiated subsidy strategies can generate higher TFP improvement returns. Government subsidies are an important means to guide the development of the energy storage industry.

Why do local governments support large-scale energy storage projects in China?

Local governments in China tend to support large-scale ESE to deploy energy storage projects rapidly and accelerate the construction of new power systems in their localities.

Why is the energy storage industry important?

Under dual-carbon targets, the development of the energy storage industry is of strategic significance for building a new energy system, improving the energy structure, ensuring energy supply, and promoting the low-carbon transition in China (He et al., 2023; Lee et al., 2023).

How can energy storage systems meet the demands of large-scale energy storage?

To meet the demands for large-scale, long-duration, high-efficiency, and rapid-response energy storage systems, this study integrates physical and chemical energy storage technologies to develop a coupled energy storage system incorporating PEMEC, SOFC and CB.
