Abstract
Currently, ACEA utilises biogas obtained from the treatment of the organic fraction of municipal solid waste for thermal and electric energy recovery through endothermic engines (3 MW, in total). By 2020, the biogas produced at the site will no longer be used as a fuel for the combined heat and power units, but it is expected to feed a purification system in order to obtain a flow of biomethane to be injected into the natural gas network. This is part of the Italian strategy to achieve the Horizon 2020 European targets aimed at promoting the renewable production of transport fuels. In order to encourage sustainability and innovative prototype technologies, ACEA has also been involved in some European research projects, in particular for the conversion of biogas into other energy carriers. furthermore, ACEA ha recently built a flexible experimental platform that can used for the validation step of prototypes in an industrial field.

66% of the electricity energy is selfconsumed, and the remaining 34% is sold to the network
Since the hydrogen production from water electrolysis is very demanding of energy, this process is sustainable only when it is possible to utilise low-price electricity and the off-peak periods of electricity production
