Highly Efficient and Low-impact InnOvative TheRmal stOrage system for enhanced disPatchability in concEntrated solar tower plants

HELIOTROPE is a groundbreaking research and development endeavor dedicated to advancing Concentrated Solar Power (CSP) technology to unprecedented heights.

This project focuses on developing state-of-the-art molten salts and materials technologies for thermal energy storage systems, pushing the boundaries of operational temperatures beyond the current industry standard of 600ºC. A holistic approach is at the heart of HELIOTROPE's mission.

Sustainable novel molten salts as thermal energy storage mediums and the remarkable ability to withstand absorber surface temperatures of up to 850ºC are introduced, promising to enhance CSP plant efficiency and dispatchability. This technological advancement aims to redefine the capabilities of CSP plants.

Furthermore, HELIOTROPE aligns closely with key European energy policies and initiatives, contributing significantly to energy security, reducing reliance on fossil fuels, and lowering greenhouse gas emissions.

The project supports the vision outlined in the European Green Deal, Clean Energy for All Europeans, and the Fit for 55 legislations, fostering sustainability and competitiveness in the energy sector.

HELIOTROPE aspires to reshape the CSP plant landscape, making them not only more efficient but also inherently environmentally friendly.

The project represents a significant stride towards a sustainable energy future, where CSP technology leads the way in innovation and progress, redefining the boundaries of what is possible in the pursuit of a cleaner, more sustainable energy world.
