- ItemOpen AccessALMIA Educativa as an educational strategy towards an effective energy transition of a rural village(2022) Arco Bravo, Isabel del; Ramos Pla, Anabel; Zsembinszki, Gabriel; Gracia Cuesta, Alvaro de; Cabeza, Luisa F.The 2030 Agenda for Sustainable Development [1] was adopted in 2015 by the United Nations (UN) and its member states with the main objective of providing a path to protect the planet from degradation and to people prosperity and world peace. A total of 17 Sustainable Development Goals (SDGs) are included in the agenda, with specific targets and actions to achieve this ambitious overarching goal. In Sustainable Development the person is key for policies and efforts to improve conditions in each social context. The three key aspects to consider are: (i) the promotion of remote human and socially equitable development for all humanity based on inclusion, (ii) the guidance of economic development at the service of human development, and finally, (iii) the promotion of responsible use of the planet’s natural resources [2]. The fast growth of population in large urban areas is expected to generate or aggravate many problems related to citizen insecurity, energy and water supply, excessive production and over-consumption, waste generation, etc. At the same time, access to affordable, reliable, sustainable, and modern energy for all people living in rural areas must be ensured. Education is a fundamental tool to build sustainable societies actively involving all citizens in the sustainable development. The objective of this paper is to describe the ALMIA project as a strategic plan for the transformation of a small village called Almatret (Catalonia, Spain) towards sustainable development as a net positive energy and sustainable village, aligned with the implementation of the 17 SDGs. This paper focuses on ALMIA Educativa as an educational strategy to make the energy transition effective in the rural village.

- ItemOpen AccessNew Concept for High Temperature Thermal Energy Storage Using a Concrete Tank(2022) Cabeza, Luisa F.; Vérez, David; Zsembinszki, Gabriel; Borri, Emiliano; Prieto, CristinaThe use of concrete is showing great potential as thermal energy storage material for concentrating solar power plants (CSP) due to its versatility, relatively low cost, and the possibility to reach a high operating temperature, above 500ºC thus increasing the plant efficiency. However, actual configurations based on concrete show different drawbacks including difficulties during the manufacturing on-site, different thermal expansion coefficients between concrete and pipes, and poor thermal conductivity of concrete. In order to address those challenges, this study proposes a new TES concrete tank concept based on three main pillars: modularity, improved concrete formulation, and direct contact concept. A preliminary assessment of the thermal performances of the new concept was analyzed through simulations showing the temperature distribution of the modules.
- ItemOpen AccessLife Cycle Assessment (LCA) of Several Concentrating Solar Plants (CSP) in Tower Configuration with Different Storage Capacity in Molten Salts(2022) Gasa, Gemma; López-Román, Antón; Prieto, Cristina; Cabeza, Luisa F.The objective of this study is to analyse the impact of the thermal energy storage system (TES) in the life cycle assessment (LCA) of a concentrating solar power plant (CSP) with central receiver technology. The study uses a base case of a plant with 110 MWel and 17.5 hours of direct storage with molten salts. First, this plant was compared with a plant of equal power but without storage. Subsequently, the LCAs of four plants with different thermal energy storage capacities, 3, 6, 9 and 17.5 equivalent hours, were compared. The results show that TES is key for solar thermal plants, not only to guarantee dispatch capacity, but also to reduce their environmental impact. Comparing different thermal storage capacities, the most environmentally efficient plant of those analysed is the one with a storage capacity of 9 h.
