This study examines the effects of transitioning to hydrogen production in the National Capital Region (NCR) and Palawan Province, Philippines, focusing on technology, environment, and stakeholder impact. This research, conducted through a July 2022 survey, aimed to assess public awareness, knowledge, risk perception, and acceptance of hydrogen and its environmentally friendly variant, green hydrogen, infrastructure. Disparities were found between urban NCR and rural Palawan, with lower awareness in Palawan. Safety concerns were highlighted, with NCR respondents generally considering hydrogen production safe, while Palawan respondents had mixed feelings, particularly regarding nuclear-based hydrogen generation. This report emphasizes the potential ecological advantages of hydrogen technology but highlights potential issues concerning water usage and land impacts. It suggests targeted public awareness campaigns, robust safety assurance programs, regional pilot projects, and integrated environmental plans to facilitate the seamless integration of hydrogen technology into the Philippines’ energy portfolio. This collective effort aims to help the country meet climate action obligations, foster sustainable development, and enhance energy resilience.

This study evaluates key technological factors for grid-scale energy storage in Palawan, Philippines, to support renewable energy integration and enhance grid stability. Using the Analytic Hierarchy Process (AHP) and input from various stakeholder groups, we assessed technology attributes such as cost-effectiveness, safety, reliability, and storage capacity. Hydrogen Energy Storage (HES) emerged as the highest-rated technology, with a score of 0.28, followed by lithium-ion batteries at 0.24. This reflects broad support from both scientific communities and the general public. The initial stakeholder evaluation highlighted three key attributes: maintainability (0.094), energy efficiency (0.092), and geographic and climatic suitability (0.085), indicating a focus on practical, localized concerns. The study emphasizes that by combining technical viability with community values, we can develop practical and inclusive off-grid energy solutions. Insights from this comprehensive evaluation provide targeted pathways for policy design, including incentives, public outreach, and equitable financing schemes. Ultimately, aligning technological solutions with social preferences and technical standards can facilitate a just and sustainable energy transition in Palawan.

This study introduces an integrated Life Cycle Assessment–Multi-Criteria Decision Analysis–Nash Equilibrium (LCA–MCDA–NE) framework to assess the feasibility of hydrogen energy storage (HES) in Philippine island grids. It starts with a cradle-to-gate LCA of hydrogen production across various electricity mix scenarios, from diesel-dominated Small Power Utilities Group (SPUG) systems to high-renewable configurations, quantifying greenhouse gas emissions. These impacts are normalized and integrated into an MCDA framework that considers four stakeholder perspectives: Regulatory (PRF), Developer (DF), Scientific (SF), and Local Social (LSF). Attribute utilities for Maintainability, Energy Efficiency, Geographic–Climatic Suitability, and Regulatory Compliance inform a 2 × 2 strategic game where net utility gain (Δ) and switching costs (C₁, C₂) influence adoption behavior. The findings indicate that the baseline Nash Equilibrium favors non-adoption due to limited utility gains and high switching barriers. However, enhancements in Maintainability and reduced costs can shift this equilibrium toward adoption. The LCA results show that meaningful decarbonization occurs only when low-carbon generation exceeds 60% of the electricity mix. This integrated framework highlights that successful HES deployment in remote grids relies on stakeholder coordination, reduced risks, and access to low-carbon electricity, offering a replicable model for emerging economies.
