“…In Lower Saxony, salt caverns were identified with a total volume of 1.1 billion m 3 , equivalent to ∼380 TWh H 2 [40]. Thema et al [41] use 70 TWh H 2 for the whole of Germany. Pressures up to 200 bar may be employed in salt caverns [42].…”

In order to achieve significant greenhouse gas emission reductions, decarbonisation of all economic sectors must be considered. Here, the authors study the provision of renewable energy for the power, district heating, transport and industrial sectors in nine North European countries by integrating a large amount of wind and solar power into the system with power-togas and power-to-fuel plants enabling balancing and sector coupling. Simultaneous optimisation of plant capacities and operation was performed. Two different synthetic liquid fuel production pathways were compared. The cost of synthetic liquid fuel remained, depending on the production pathway and amount, 30-120% higher than estimated fossil alternative cost. Biomass potential emerged as a limiting factor with high shares of biomass-based synthetic liquid fuel production. The need for energy storage system was estimated. The total optimal capacity of synthetic natural gas, hydrogen, synthetic liquid fuel, and heat storages varied between 37 and 54 TWh (1.7-2.5% of energy demand) depending on the scenario, when emergency stocks were not included. The cost of energy storages remained small compared to the total system cost, with heat storages exhibiting the highest cost.

“…At present, a variety of applications of PtG technology have been developed to produce methane or hydrogen [12], to balance wind and solar power fluctuations and to increase the security of supply [13]. Renewable intermittent power must be managed via the future development of storage technologies [14], and massive energy storage alternatives [15] are needed to store excess electricity generated by RES.…”

“…Despite the current barriers of PtG, which relate mainly to its high costs and efficiency rates obtained at the development stage, it has been identified as a cost-efficient option for renewable gas and a long-term storage solution. PtG contributes to the decarbonization of different sectors and allows the substitution of European energy carriers based on fossil fuels [13]. However, at present, these technologies face numerous barriers to their deployment in the European Union, and, in particular, in Southern Europe.…”

“…The academic literature has analyzed the impact of PtG on future energy systems in European [10,12,14,17] and non-European [18] countries. In particular, the impact of these technologies in the German energy transition scheme has been examined extensively by different authors [11,13,19]. Technical parameters and technology costs have been analyzed, and a consensus reached that PtG is a sustainable solution for decarbonization.…”

Methodology for Dimensioning the Socio-Economic Impact of Power-to-Gas Technologies in a Circular Economy Scenario

Innovative and sustainable energy technologies are needed in the transition of energy toward a circular economy. Because of the use of renewable energy and carbon utilization, power-to-gas could be a cutting-edge technology that supports the circular model in future sustainable energy markets. However, this technology faces new technical and socio-economic challenges. The use of power-to-gas is limited because of barriers that limit the mobilization of investment capital. In addition, social and economic impacts on the territories in which these facilities are located are under study. In this context, the aims of this paper are: (i) To explore the determinants and barriers for power-to-gas technology to enhance the understanding of investment in innovative energy technologies; and (ii) to support effective policymaking and energy companies’ decision-making processes. This study defines and measures, from a circular economy perspective, the main impacts of the deployment of this technology on a territory in terms of volume of investment, employment generation, and CO2 capture. The study also provides a simplified methodology to contribute to the analysis of the use of power-to-gas. Finally, it improves the knowledge of the socio-economic impact of this cutting-edge technology for the transition of energy to a zero-emission scenario.

“…Power-to-Gas, also called PtG, is an essential technology to convert the energy sector into a renewable system which can provide the required long-term storage capacity and reduce carbon footprints by gradually substituting fossil feedstocks with renewable gas [9,10]. The technology uses renewable electric power to produce hydrogen by electrolysis (Power-to-Hydrogen), which then can be further converted into methane with carbon dioxide from an external source in the methanation step (Power-to-Methane).…”

Power-to-Methane as one part of Power-to-Gas has been recognized globally as one of the key elements for the transition towards a sustainable energy system. While plants that produce methane catalytically have been in operation for a long time, biological methanation has just reached industrial pilot scale and near-term commercial application. The growing importance of the biological method is reflected by an increasing number of scientific articles describing novel approaches to improve this technology. However, these studies are difficult to compare because they lack a coherent nomenclature. In this article, we present a comprehensive set of parameters allowing the characterization and comparison of various biological methanation processes. To identify relevant parameters needed for a proper description of this technology, we summarized existing literature and defined system boundaries for Power-to-Methane process steps. On this basis, we derive system parameters providing information on the methanation system, its performance, the biology and cost aspects. As a result, three different standards are provided as a blueprint matrix for use in academia and industry applicable to both, biological and catalytic methanation. Hence, this review attempts to set the standards for a comprehensive description of biological and chemical methanation processes.
