a b s t r a c tThe Power-to-Gas (PtG) process chain could play a significant role in the future energy system. Renewable electric energy can be transformed into storable methane via electrolysis and subsequent methanation.This article compares the available electrolysis and methanation technologies with respect to the stringent requirements of the PtG chain such as low CAPEX, high efficiency, and high flexibility.Three water electrolysis technologies are considered: alkaline electrolysis, PEM electrolysis, and solid oxide electrolysis. Alkaline electrolysis is currently the cheapest technology; however, in the future PEM electrolysis could be better suited for the PtG process chain. Solid oxide electrolysis could also be an option in future, especially if heat sources are available.Several different reactor concepts can be used for the methanation reaction. For catalytic methanation, typically fixed-bed reactors are used; however, novel reactor concepts such as three-phase methanation and micro reactors are currently under development. Another approach is the biochemical conversion. The bioprocess takes place in aqueous solutions and close to ambient temperatures.Finally, the whole process chain is discussed. Critical aspects of the PtG process are the availability of CO 2 sources, the dynamic behaviour of the individual process steps, and especially the economics as well as the efficiency.

“…In [16], the economic potential of a grid-balancing system based on traditional gas turbine plants with innovative P2G plants was evaluated, which can effectively contribute to reducing the uncertainty of dispatch plans. Furthermore, [17] investigates the economic feasibility of P2G systems and gas storage options for both hydrogen and renewable methane. In [18], the energy hub concept was used to model and evaluate the economics of P2G.…”

The power-togas (P2G) technology-a promising way to connect power and gas networkswill be widely used in the power-gas-heating integrated system (PGHIS) to promote its operational flexibility. However, the higher operational costs will affect the application of P2G on PGHIS scheduling, which cannot be ignored. In this paper, a PGHIS scheduling model considering the P2G cost and wind power utilization is proposed to analyze the impact of the P2G cost characteristics. First, a PGHIS including P2G is introduced, and different kinds of P2G operational costs are clarified to capture the cost characteristics of the P2G. Then, a multi-objective day-ahead scheduling model of the PGHIS is proposed to coordinate the tradeoff between its operational costs and the wind power utilization. Finally, the ε-constraint and entropy weight methods are used to solve the multi-objective model. The numerical results demonstrate that P2G cost characteristics can significantly affect the day-ahead scheduling of the PGHIS, and the proposed model can effectively achieve a compromise solution. INDEX TERMS Cost characteristics, day-ahead scheduling, integrated energy system, power-togas (P2G), wind power utilization.

“…Because of its low permeability and good self-healing capacity, salt rock is recognized as an ideal medium for large-scale energy high capacity storage (Yang et al, 2015) such as strategic petroleum reserves (SPR) (Liu et al, 2016;Zhang et al, 2017), compressed air energy storage (CAES) (Aghahosseini and Breyer, 2018;Budny et al, 2015;Wang et al, 2016;Wang et al, 2018), hydrogen energy storage (Le Duigou et al, 2017;Ozarslan, 2012;Slizowski et al, 2017b),and particularly natural gas storage (Liu et al, 2018;Wang et al, 2013).…”

Underground TWH caverns in salt rock have high construction efficiency and large usable volumes and provides an ideal space for large-scale natural gas storage. In this study, the solution mining process of TWH cavern is thoroughly analyzed. Applying basic principles of the Navier-Stokes equation method and reasonable assumptions, we established a new 3D mathematical model which includes flow and mass transfer and boundary movement for TWH salt cavern construction. Then, the velocity field and the concentration field can be solved by the SIMPLE algorithm, while the boundary movement of cavern expansion can be solved by the VOF algorithm. We developed a new VC++ computer code program TWHSMC for solution mining and herein we present the numerical results. Finally, the simulation cavern shapes results by program are compared with the experimental ones. The results indicate that our model successfully and accurately predicts the cavern shape and demonstrates the reliability and applicability of the model.
