Description du projet
Concept hybride de production d’énergie électrique et thermique
Une production et un stockage efficaces de l’énergie solaire sont essentiels pour une énergie durable. Le projet ASTERIx-CAESar, financé par l’UE, développe une centrale héliothermoélectrique de haute performance qui intègre une solution de stockage de l’électricité. Elle intègre l’énergie solaire concentrée à base d’air et à récepteur central au stockage d’énergie à air comprimé pour maximiser l’efficacité de la conversion énergétique et faciliter la gestion de l’énergie pour les réseaux électriques. Ceci permettra d’élaborer de nouvelles stratégies opérationnelles et de nouveaux modèles commerciaux. Ce concept hybride innovant jette les bases d’une ère futuriste où des centrales électriques renouvelables adaptatives produiront à la fois de l’énergie électrique et de l’énergie thermique, fournissant de la chaleur industrielle et soutenant le dessalement par osmose inverse.
Objectif
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.
