Carbon peak and energy storage

What is a carbon peak?

“Carbon Peak” refers to reaching a point in time when CO2 emissions reach their peak and gradually decline thereafter.

What is CO2 energy storage (CCES)?

The technology of compressed carbon dioxide (CO 2) energy storage (CCES) is further proposed according to CAES as well as CO 2 power cycle. Because of the distinct thermophysical characteristics of CO 2, CCES exhibits superior performance. Firstly, CO 2 has a high critical temperature (304.5 K).

What are China's Carbon peaking objectives?

Based on the “Carbon Peaking Action Plan before 2030” issued by the Chinese government, China’s carbon peaking objectives are as follows: non-fossil fuel energy shares should reach 20% and 25% by 2025 and 2030, respectively; CO 2 emissions per unit of GDP in 2025 should decrease by 18% from 2020 levels, with the carbon peak achieved by 2030.

How do we estimate carbon storage in the 21st century?

Recent global-scale studies focusing on mapping carbon storage in the first two decades of the 21st century exemplify divergent approaches to carbon storage estimation. For example, used machine learning to derive Above Ground Biomass (AGB) estimates from satellite data and environmental features.

What is compressed carbon dioxide storage (CCES)?

As a type of energy storage technology applicable to large-scale and long-duration scenarios, compressed carbon dioxide storage (CCES) has rapidly developed. The CCES projects, including carbon dioxide battery in Italy and carbon dioxide storage demonstration system in China, have also been completed.

What is a carbon storage model?

Carbon storage models address three broad issues: (1) historical time-series reconstruction, (2) nowcasting and (3) forecasting of potential estimations. Like in most modelling problems, there is no universally accepted model solution. This results in a variety of approaches suited to specific contexts of application.
