As coal plants shut down, many places face the loss of jobs and taxes. But in Colorado, one town hopes to transform a coal plant into a new kind of renewable energy storage.
From this point of view, carbon peak, carbon neutralization has become the primary goal of China and the world development. Since primary energy accounts for the vast bulk of global energy consumption, as seen in Fig. 3.Therefore, in order to achieve the dual-carbon goal faster and better, the transformation of energy structure has become …
The residual elastic strain energy is stored in the coal. The above energy conversion mode is repeated for each crack propagation until the coal specimen completely fails. It can be seen that the dissipation and release of elastic strain energy is the direct embodiment for coal failure. Thus, elastic strain energy is the root of coal failure.
