Opportunities of power-to-gas technology in different energy systems architectures.

Highlights • Power-to-gas can provide energy storage for renewable energy storage. • PtG can play different roles in different energy systems. • PtG can support the transition of energy system toward sustainability. • PtG can be an important source of renewable gases such as hydrogen, methane or SNG. Abstract This paper presents an overview of power-to-gas opportunities. Power-to-gas technology is gaining more and more popularity. It can provide large and long-term storage for increasing share of renewable sources in the energy system. In this paper, we would like to review the role of the power-to-gas system in different energy system architectures. Authors have analyzed the literature in the context of the problems, which could be solved by power-to-gas technology. Additionally, different assessment such as techno-economic, Life Cycle Assessment and Multi-criteria decision analysis for power-to-gas were revised. [ABSTRACT FROM AUTHOR]
