Descripción del proyecto
Concepto híbrido para la producción de energía eléctrica y térmica
La energía solar eficiente y el almacenamiento son cruciales para la energía sostenible. El equipo del proyecto ASTERIx-CAESar, financiado con fondos europeos, está desarrollando una central termosolar de alta eficiencia que incorpora una solución integrada de almacenamiento de electricidad. Integra la energía solar concentrada basada en aire y de receptor central con el almacenamiento de energía en aire comprimido para maximizar la eficiencia de la conversión energética y facilitar la gestión eficaz de la energía en las redes eléctricas. Como resultado, permitirá la creación de nuevas estrategias operativas y modelos de negocio. Este innovador concepto híbrido está sentando las bases de una era futurista en la que las centrales renovables adaptables generarán tanto energía eléctrica como térmica, proporcionando calor de proceso y apoyando la desalinización por ósmosis inversa.
Objetivo
Highly efficient energy conversion of solar power and storage will play a vital role in a future sustainable energy system. Thus, this project focuses on the development of a novel high-efficiency solar thermal power plant concept with an integrated electricity storage solution. The project combines air-based central receiver Concentrated Solar Power (CSP) and Compressed Air Energy Storage (CAES) to maximize conversion efficiency and power grid energy management, enabling a new operation strategy and business models. The hybrid concept initiates a futuristic era with adaptive renewable power plants, producing both electrical and thermal energy, including process heat supply and reverse osmosis desalination. Because cheap off-peak electricity is used to provide the air compression work of the topping Brayton cycle, the overall peak solar-to-electric energy conversion efficiency of the proposed power plant may reach up to 40% efficiency, which roughly doubles the peak efficiency with respect to state-of-the-art CSP technology. The project’s activity will cover the techno-economic-environmental optimisation of the innovative CSP-CAES plant using representative boundary conditions, provided by grid operators and specialised partners, as well as the development and extensive testing of key components needed for its implementation. The main development will cover: (i) an advanced high-efficiency solar receiver, (ii) optical sensors and AI-based control, (iii) optimized CAES with heat exchangers and compressor/expander detailed designs and (iv) innovative integration of desalination. The proposed technology is set forth by an interdisciplinary partnership spanning the entire CSP value chain. Targeting a TRL of 6-7, the ASTERIx-CAESar concept will be validated with a demonstration scale of 480 kWth prototype in a relevant environment.
