Approaches for Dispatchable Biomass Plants with Particular Focus on Steam Storage Devices
An increasing share of fluctuating energy generation leads to new challenges in power grids. In addition, the demand for flexible power plants is growing. Solid biomass-fueled combined heat and power (CHP) plants are able to get modified into dispatchable power plants. Boundaries for this operation mode are summarized and several measures to achieve a flexible power generation in biomass CHP plants are concluded. The integration of a high-temperature storage system for buffering the plants' steam seems to be the most promising, however, the least investigated option. The tasks and necessary features of such storage systems were investigated and an overview of available technologies and systems for the storage of steam is given.
