The role of power-to-gas in the integration of variable renewables

Abstract : Limiting the raise of global temperatures requires a rapid and massive deployment of solution to reduce carbon emissions at all levels. The development of intermittent renewable energy resources has received significant support from governments, and its production will considerably increase. The introduction of this high electrical production presents some challenges, in particular, the allocation of high production in low consumption periods. One of the most promoted solutions to cope with this challenge is the integration of power-togas technologies (P2G). In this sense, the European Union, and some of its members have presented their plans supporting the production and consumption of hydrogen. At the same time, it can be noted that the development strategies for these technologies are largely deployed at the local level. To allow local territories to contribute to the decarbonization of the energy system, national governments are extending the application of its energy policy to its territories. This is the case in France that over the last decades, has adopted laws to extend the application of its energy policy at local level, with the objective of ensuring better, faster deployment of its energy transition and reaching the carbon neutrality by 2050. As a result, the French regions have targeted objectives for the development of their local energy resources. The SUD Provence-Alpes-Côte d'Azur Region (PACA) in southern France, in response to these air, energy, environment, and climate change adaptation responsibilities, has targeted as objective to reach the carbon neutrality by 2050, which is concerned by the massive development of solar photovoltaic production as the region has considerable access to solar resources. The region as well has presented a hydrogen plan to support the development of this energy in the region and contribute to the national efforts. This study, conducted with TIMES PACA a bottom-up optimization model representing the energy system of the PACA region, analyzes how P2G technologies contribute to the development of solar resources. Results show that P2G technologies are essential for the decarbonization of the regional energy system and the renewable deployment, what is needed to the national and global decarbonization objectives and is expected to structure the whole hydrogen chain.
