“…PtG was found to be favored for large-scale uses (i.e., bulk, distributed and commercial storage including for hydrogen-fueled mobility, renewables integration, frequency regulation), but less suitable for kW-scale applications such as residential energy storage, where batteries scored higher than PtG. Study [12] did not involve any Canadian regional scenario-based analysis, but provided a generic technology screening methodology with preliminary results on the suitability of PtG, prior to the detailed evaluation of PtG deployment schemes.…”

“…As of 2013-2016, the shares of renewables in the Canadian energy and power sector were of approximately 27% and 66%, essentially consisting of base-load hydroelectricity (i.e., 63% of total electricity generation), with supplemental wind (i.e., 2%) and solar generation (i.e., <1%) [12,[104][105][106]. Approximately 80% of the country's 2016 annual electricity production was zero carbon (including nuclear, hydro, wind, solar), with a recommended 100% goal in 2050 (also including biomass and tidal) [107].…”

“…Walker et al [12] applied an analytical hierarchy process (AHP) to compare the suitability of PtG and other energy storage technologies (e.g., flywheels, batteries, pumped hydroelectric storage, compressed air energy storage) for small-to large scale applications, including residential and bulk energy storage, and utility-scale frequency regulation. AHP was applied as a decision tool to the selection of the best storage technology, with this decision objective broken down into weighted criteria.…”

Technical, economic and environmental assessments of projected power-to-gas (PtG) deployment scenarios at distributed-to national-scale are reviewed, as well as their extensions to nuclear-assisted renewable hydrogen. Their collective research trends, outcomes, challenges and limitations are highlighted, leading to suggested future work areas. These studies have focused on the conversion of excess wind and solar photovoltaic electricity in European-based energy systems using low-temperature electrolysis technologies. Synthetic natural gas, either solely or with hydrogen, has been the most frequent PtG product. However, the spectrum of possible deployment scenarios has been incompletely explored to date, in terms of geographical/sectorial application environment, electricity generation technology, and PtG processes, products and their end-uses to meet a given energy system demand portfolio. Suggested areas of focus include PtG deployment scenarios: (i) incorporating concentrated solar-and/or hybrid renewable generation technologies; (ii) for energy systems facing high cooling and/or water desalination/treatment demands; (iii) employing high-temperature and/or hybrid hydrogen production processes; and (iv) involving PtG material/energy integrations with other installations/sectors. In terms of PtG deployment simulation, suggested areas include the use of dynamic and load/utilization factor-dependent performance characteristics, dynamic commodity prices, more systematic comparisons between power-to-what potential deployment options and between product end-uses, more holistic performance criteria, and formal optimizations.

“…Besides the four aspects mentioned above, the PtG technologies also can be implemented in other energy sectors such as providing renewable fuels in transportation, utilizing waste heat in a heating system and participating in chemical industry [19][20][21][22]. However, these extensive applications of PtG technologies will only be briefly introduced, as this paper mainly focused on analyzing the economic potentials of PtG technologies in electric power systems.…”

Regarded as a long-term, large capacity energy storage solution, commercialized power-to-gas (PtG) technology has attracted much research attention in recent years. PtG plants and natural gas-fired power plants can form a close loop between an electric power system and a natural gas network. An interconnected multi-energy system is believed to be a solution to the future efficient and environmental friendly energy systems. However, some crucial issues require in-depth analysis before PtG plants can be economically implemented. This paper discusses current development status and potential application of PtG plants in the future interconnected multi-energy systems, and further analyzes the costs and benefits of PtG plants in different application scenarios. In general, the PtG plants are not economical efficient based on current technologies and costs. But the situation is likely to change with the development of PtG technologies and interconnected operation of gas-electricity energy system.

“…They highlight the importance of offgrid solutions that are cost-competitive and benchmark realistic costs of a small scale hydrogen production system. Walker et al, Götz et al, Garcia et al and Rönsch et al [3][4][5][6] highlight the various energy recovery pathways of the power to gas concept. Walker et al's work [3], shows the potential use of hydrogen produced from surplus electricity in the transportation, industrial sector, and the natural gas sector as a fuel.…”

There is a need for energy storage to improve the efficiency and effectiveness of energy distribution with the increasing penetration of renewable energy sources. Among the various energy storage technologies being developed, 'power-to-gas' is one such concept which has gained interest due to its ability to provide long term energy storage and recover the energy stored through different energy recovery pathways. Incorporation of such systems within the energy infrastructure requires analysis of the key factors influencing the operation of electrolyzers and hydrogen storage. This study focusses on assessing the benefits power-to-gas energy storage while accounting for uncertainty in the following three key parameters that could influence the operation of the energy system: (1) hourly electricity price; (2) the number of fuel cell vehicles serviced; and (3) the amount of hydrogen refueled. An hourly time index is adopted to analyze how the energy hub should operate under uncertainty. The results show that there is a potential economic benefit for the powerto-gas system if it is modeled using the two-stage stochastic programming approach in comparison to a deterministic optimization study. The power-to-gas system also offers environmental benefits both from the perspective of the producer and end user of hydrogen.
