abstract = {Decarbonization and growth of variable renewable generation have increased interest in hydrogen as a low-carbon energy carrier. Underground hydrogen storage in geological formations is one of the few scalable options for large-capacity energy storage, and retrofitting existing natural gas infrastructure to store methane–hydrogen blends offers a practical transition pathway. Yet valuing such storage contracts is difficult because hydrogen markets remain immature. This paper develops a real-options framework for methane–hydrogen storage contracts with a prescribed hydrogen energy fraction. Extending the Hamilton–Jacobi–Bellman approach used for natural gas storage, the model incorporates stochastic hydrogen prices and blend-specific operational constraints, including reduced effective energy capacity. Contract values and optimal operating policies are computed by solving a multi-factor HJB equation with a semi-implicit finite-difference scheme. The framework is verified against natural gas benchmarks and assessed by Monte Carlo cash-flow evaluation. Results show how value and policies depend on blend ratio, volatility, capacity, and contract duration.},

abstract = {The article presents the findings of a research project that focuses on the role of rural areas as key players in addressing the current climate emergency. The article addresses the challenge of a just energy transition by examining the obstacles to the implementation of renewable energy infrastructure. The investigation is situated within the context of Galicia, a rural region in the northwest of Spain. The study conducted an extensive review of the literature, surveys, and interviews, which revealed a significant gap between local communities and planning decisions to be one of the primary obstacles to a just transition. In light of these findings, the research puts forth an integrated planning methodology founded on social and metabolic principles. This methodology investigates the communal management of energy resources with the objective of improving local welfare and integrating this into the planning process. This methodology proposes a series of steps and associated tools for the analysis of the potential for local energy generation using biomass, hydropower, solar, and wind infrastructures. Landscape and social considerations are articulated through continuous community engagement. The energy generation capacity will be used as a catalyst to address the most pressing issues and to improve living conditions in rural areas. The article confirms the need for a holistic approach to energy infrastructures, paying particular attention to landscape integration and endogenous development.},

abstract = {The energy transition is one of the most important processes of the last decade in Spain, affecting all aspects of life (social, political, economic and demographic). Its main objective is to eventually replace the fossil-fuel-based energy matrix with renewable energy sources to avoid climate change and meet sustainable development goals. This transition has affected a large number of population groups and institutions in carbon-intensive regions such as As Pontes, who are the main stakeholders in this process. These stakeholders have generated different narratives around the implementation of decarbonization policies and their short- and long-term impacts on the local population and the territory. These narratives affect the acceptance and pace of implementation of decarbonization measures and policies adopted by national and regional governments. Based on a qualitative analysis of published material (press articles, policy reports published by central and regional governments, reports published by environmental groups, financial institutions and large companies), this article first identifies the different stakeholders involved in the decarbonization process and maps them according to their power and interest in the energy transition process and then highlights the prevalent energy transition narratives, with their impact on the pace of the energy transition in Spain, focusing on the case of As Pontes. The results show that the narratives propagated by different stakeholders have a great impact on the acceptance of the decarbonization policies and measures adopted by the central government and the pace of the energy transition in different parts of Spain, including the region of As Pontes.},
