Abstract

The waste management and the energy storage from intermittent renewable sources are considered to have a strategic role in the field of the energy production and environmental protection according to the promotion of the renewable power plants and to the waste treatment with low pollutant emissions. For this reason, in this paper a novel approach to these topics is proposed by introducing a hybrid storage power plant based on the energy production from the renewable energy sources and on the waste gasification by means of the plasma arc technology. The idea is based on the hydrogen production from renewables and its utilization as plasma gas in a plasma gasification process that is considered one of the most effective and environmentally friendly methods for solid waste treatment and energy utilization. The hybrid storage power plant consists in the coupling of the Hydro-Plasma Gasification Combined Cycle (HPGCC), where the waste to energy conversion is realized, with the renewable hydrogen production unit (RHPU), in which the renewable energy is electrochemically split into hydrogen and oxygen by electrolysis. The hybrid storage power plant has been studied by using a numerical model that, by estimating both the syngas composition and the energy required for the gasification reactions, has allowed to estimate the overall plant performance. Results show that the overall efficiency of the HPGCC plant is very high (over 40%) in comparison with the efficiency of conventional technologies based on waste incineration (20%) and the storage efficiency (~70%) is comparable with high efficiency energy storage systems such as CAES system.
