- Portugal Offshore Wind, Green Hydrogen, and Sustainable Fuels: Power-to-X PathwaysPublication . Simoes, Sofia; Portillo, Juan C. C.; Simões, Teresa; Estanqueiro, Ana; Catarino, Justina; Costa, Paula; Oliveira, Paula; Ribeiro Pinto, Paulo Jorge; Lopes, Fernando; Lopes, Tiago; Gano, António; Duarte de Castro Fontes, Maria Margarida; Gírio, FranciscoABSTRACT: Portugal has a vast coastal area and significant offshore wind resources. The country has set ambitious targets and designated specific areas for offshore wind development. Current national policies are actively encouraging investment in these projects. This report compiles the latest strategies for offshore wind and green hydrogen in Portugal. It introduces the Power-to-X (P2X) concept, explores potential offshore wind-based P2X business models, and outlines the key processes and technologies involved. It also maps potential consumers of green hydrogen, along with the associated supply chains for hydrogen and sustainable fuels. A techno-economic analysis was conducted to identify viable pathways for Portugal. This involved selecting one of the planned offshore wind zones and, based on its location and potential capacity, determining the optimal onshore site and scale for a hydrogen and sustainable fuels hub. The report presents a comparative evaluation of seven scenarios, offering valuable insights for both public and private sector stakeholders.
- Stakeholder views of land conflicts in utility-scale solar energy: toward a spatial assessment toolPublication . Alves, André; Simoes, SofiaABSTRACT: Renewable energy sources (RESs) power plants, particularly solar photovoltaic (PV) infrastructure, are being deployed at an unprecedented scale to allow the transition to carbon neutrality. Rapid expansion of PV facilities cannot proceed without careful consideration of spatial planning and environmental impacts. Although social acceptance of RES is generally high, there is little consensus on where such plants should be located, as stakeholders perceive their impacts in diverse and often conflicting ways. This study aimed to (i) assess the spatial distribution of planned utility-scale solar power plants (SPP) in Portugal in relation to environmentally and culturally sensitive areas; (ii) analyse stakeholder perceptions of SPP impacts across different land uses and territorial settings; and (iii) develop an impact index that incorporates stakeholder information to classify PV projects by degree of impact. An online survey was conducted to examine perceived impacts associated with SPP development, and a classification methodology was designed using an additive aggregation method to produce a geographic information system-based index to classify projects. The questionnaire answers reveal substantial heterogeneity in individual preferences but also indicate intragroup convergence and intergroup divergence among stakeholder groups. The impact index provides a framework for classifying land-use conflicts related to large-scale solar projects and enables preliminary assessment of planned developments in relation to stakeholder alignment. These findings contribute to spatial energy planning by demonstrating how stakeholder perceptions of land-related impacts can be operationalised to inform siting decisions for RES plants.
