Flexible bioenergy supply for balancing fluctuating renewables in the heat and power sector—a review of technologies and concepts

摘要

Today bioenergy plays a major role in the renewable energy provision, for heat and power and for liquid biofuels as well. With an increasing share of renewables on the one hand side and a limited availability of biomass on the other hand, the provision of bioenergy has to consider the demands of the future energy system with high shares of fluctuating wind and solar power. This includes new and improved technologies and concepts for biogas, biomethane, and liquid and solid biofuels, which are discussed in the following, while for the electricity sector, the demand for more flexible provision might take place in the years to come; for more flexible heat provision, the transition is expected in a longer time frame. For their market implementation adopted regulatory framework and price signals from electricity markets are necessary.
