- Competing water uses between agriculture and energy: Quantifying the future impacts of climate change for the Portuguese power sectorPublication . Fortes, Patricia; Simoes, Sofia; Brás, Teresa; Amorim, FilipaABSTRACT: This paper analyses to which extent the competition for water resources between water demand for agriculture and hydropower may affect the future Portuguese carbon-neutral power sector under RCP8.5 climate scenario. Climate change effects on the availability of wind, solar PV and electricity demand are also modelled by the energy system eTIMES_PT model. Results show that, by 2050, Portuguese irrigation water demand is projected to increase between 3.5%-9.7% and 19% in Douro watershed, responsible for more than 50% of the national hydropower production. Consequently, annual average hydropower capacity factor reduces around 9-10%. Comparing with historical average hydrological years, climate change can lead to a reduction of hydropower production between -9% to -30%, which may be aggravated to -21% to -39%, with water competition. This reduction is compensated with a rise of Offshore Wind less affected by climate change.
- European policies on Circular Economy and Climate Mitigation: synergies or antagonisms?Publication . Trindade, Paula; Barbosa, Juliana; Amorim, Filipa; Simoes, Sofia; Lima, Ana TeresaABSTRACT: The main objective of this paper is to review policy goals, measures and instruments across the following policy areas: climate, energy; environment (including CE) and industry. This review's objective is twofold: (1) to assess and characterise synergies and antagonisms among policy domains regarding CE and climate mitigation, and (2) to identify innovative and effective policy approaches for integrating CE into climate action. The analysis will focus on the EU+ policy level, with some incursions at Member State level (+UK) for the cases where best practices in integrating CE policies are identified. The policies assessment will feed into the climate mitigation scenarios for circular construction.
- New Greenhouse Gas simulation and mapping tools to support local carbon neutrality agendas: application to the city of AlmadaPublication . Amorim, Filipa; Simoes, Sofia; Barbosa, Juliana; Oliveira, Paula; Trindade, Paula; Aelenei, Laura Elena; Catarino, Justina; Viana, Susana; Figueiredo, LeonorABSTRACT: The aim of this work is to develop three innovative decision support tools: (1) a scenario tool that enables users to interactively design scenarios of activity variables that support decarbonisation trajectories on a local scale; (2) a mitigation tool that translates scenarios into greenhouse gas (GHG) emissions, taking into account the identification and prioritisation of the most innovative, cost-effective mitigation options (technological and behavioural) for Portuguese municipalities; and (3) a mapping tool to identify GHG emissions ‘hot spots’ on a local scale. In the first phase, these tools are applied and tested for the case study of the city of Almada in support of the ‘Agenda for a Carbon Neutral Almada by 2050’. These tools will also contribute to the training and involvement of local stakeholders, to improve the design of local GHG emissions mitigation strategies and roadmap. In the second phase, these tools will be further developed so they can be used in other Portuguese municipalities.
- Simulated hydropower production under climate change scenarios at Torrão reservoir, in northern PortugalPublication . Diogo, Paulo; Mujtaba, Babar; Beça, Pedro; Simoes, Sofia; Fortes, Patricia; Amorim, FilipaABSTRACT: Climate conditions have a significant impact on energy demand and production. The project CLIM2POWER, completed in 2021, aimed to develop a climate service at European scale for the planning of the power infrastructures operations using seasonal forecasts and long-term climate projections. This work presents part of the project, and focus on assessing the climate change impacts on hydropower production of Torrão Dam. Torrão reservoir is located on the Tâmega river, a tributary of the Douro river in northern Portugal. The long-term (2016-2100) climate data used is obtained from the EURO-CORDEX simulations, on a daily time scale. Two different combinations of regional and global climate models for scenarios RCP 4.5 and 8.5 (four combinations) were used: ICHEC-EC-EARTH-CLMcom-CCLM4 (CCLM4) and ICHEC-EC-EARTH-DMI-HIRHAM5 (HIRMAM5). Long-term precipitation data was bias-corrected using the multiplicative shift method, and for rainfall-runoff simulation, HEC-HMS model was used. The results showed that 30-years total annual precipitation for future periods (i.e, 2016-2040, 2041-2070 and 2071-2100) was 3.4%-28.1% lower than the historical one. 30-years annual total discharges of all future periods decreased for both models and RCPs (1.2%-30.2% less than the historical ones). Regarding future 30-year annual average capacity factors, there was reduction (1.8%-24.8%) with respect to historical one, except in two future periods for CCLM4 model of RCP 4.5 scenario i.e., 1.2% increased in the period 2016-2040 and 1.5% increased in the period 1971-2100. This suggest that hydropower production is not only dependent on future precipitation trends but also on the hydropower production procedures.
