Abstract: The provided is energy storage method and device for biomass cascade pyrolysis coupled with new energy power generation. The key point of the technical solution is that, with inexpensive, clean and safe biomass as energy storage medium, the redundant unstable electric energy is converted by a cascade pyrolysis energy storage system into an easy-to-store liquid and solid chemical energy in biomass pyrolytic products, and based on use requirements, can be further converted into clean fuels for power generation or exported renewable chemicals, so as to realize continuous stable output of the new energy power generation systems. Furthermore, the cascade pyrolysis energy storage system can, based on the principle of “energy level matching”, fully recover and utilize the electric energy, high-temperature heat energy and low-temperature heat energy generated in pyrolysis processes, thereby maximizing the energy utilization efficiency of the system.
