Works with compressed gases. Primarily focussing on the manufacture and upkeep of methane generating plants, Louderspring can be contracted to provide gaseous fuel, but also for a larger fee, can install the structures required for an organisation to produce and create its own natural gases. The basic plant costs between £750,000 and £1m. A plant generating 1,000m³ of biomethane, with gas piping and connections to other systems would cost around £15m
