energibuffer

Energibuffer is a storage or buffering system designed to temporarily hold energy, smoothing variations between energy supply and demand. It serves as an interface between generation, especially intermittent sources such as wind and solar, and end use, helping to stabilize grid frequency, limit voltage swings, and provide ramping support during abrupt changes in production or demand.

Common forms of energibuffers include electrical storage devices such as batteries, including lithium-ion and flow types, capacitors, and flywheels; thermal buffers such as hot water tanks or phase change materials; and chemical buffers like hydrogen storage. Hybrid configurations combine several technologies to balance costs, efficiency, and response time.

Control systems coordinate charging and discharging, accounting for state of charge, efficiency, equipment aging, and market signals. Performance metrics include capacity (energy stored), power rating (how fast energy can be released), round-trip efficiency, and cycle life. Applications vary from rapid frequency regulation to longer-term peak shaving and renewable integration.

Typical deployments include microgrids, remote installations, industrial facilities, and electric vehicle charging hubs. Energibuffers also support resilience by providing backup energy during outages and enabling more robust scheduling of generation and loads. Economic and regulatory factors, safety, and environmental impact influence selection and siting.
