High-tech production plants, usually with fully-automated processes, make it possible to use biomass to generate energy. These plants are, by nature, expensive and the fully-automated processes and procedures susceptible to disturbances.
As the fermentation and gas tanks contain a mixture of gas and air, these parts of the plant are classified as potentially explosive.

A reliable system of protection against lightning and surges is needed to safeguard the high availability and smooth operation of biogas plants.
