Yes, there are specific challenges in non-China markets that contribute to the higher costs of thermal energy storage (TES) systems compared to China.
Key Challenges Driving Up TES Costs in Non-China Markets
- Lower Scale and Commercialization Levels: China has much greater adoption of long-duration energy storage (LDES) technologies, including TES, with gigawatt-hour scale projects already underway. In contrast, other countries are still in early commercialization stages. This difference in scale and maturity drives economies of scale and cost reductions in China that are not yet realized elsewhere.
- Domestic Market Conditions: Cost advantages in China stem from factors like lower domestic labor rates and extensive government subsidies. These conditions significantly reduce installation and operational costs but are difficult to replicate in other countries with higher labor costs and different subsidy frameworks.
- Policy and Market Support Gaps: Non-China markets such as the U.S., U.K., India, and Australia are focused on developing energy storage but still require clearer policy support and procurement timelines for LDES, including TES. The lack of aggressive supportive policies can slow deployment and keep costs higher due to smaller market sizes and limited demand push.
- Grid Design and Integration Challenges: Traditional electricity grids outside China are often not designed around storage technologies, including TES, which complicates integration and increases costs. TES can be less energy-dense and harder to integrate efficiently, especially with heat pumps and in utility-scale grid balancing applications, which can raise the overall cost and complexity in these markets.
- Limited Applications and Efficiency Factors: TES has niche applicability, particularly in buildings and district heating, rather than broad utility-scale use outside China. The additional space, weight, and sometimes limited tangible local benefits can make TES a less attractive, costlier investment.
Summary Table
| Challenge | Impact on TES Cost/Adoption | China vs. Non-China Market |
|---|---|---|
| Scale and Commercialization | Higher scale lowers per-unit costs | China has large-scale projects; others early stage |
| Labor Costs and Subsidies | Lower labor and government support reduce costs | China benefits from low labor costs and strong subsidies |
| Policy and Market Development | Lack of clear policies slows deployment | China has favorable policies; others developing |
| Grid Design and Integration | Complex integration increases costs | Grids in non-China markets often less storage-ready |
| Application Niche and Efficiency | Limited applications raise cost/limit ROI | TES more widely backed and integrated in China |
Thus, the higher cost of thermal energy storage in non-China markets is primarily driven by lower deployment scale, less favorable labor and subsidy conditions, policy and grid challenges, and limited application scope, which together raise installation and operational costs compared to China.
