Thermal Storage

Delivering dispatchable renewable energy through thermal storage innovation

Thermal storage is one of the most effective technologies to provide dispatchable renewable energy

At Sener, we believe that thermal storage is one of the most effective technologies to provide dispatchable renewable energy — enabling solar plants and industrial systems to decouple generation from consumption and operate continuously, day and night. Our thermal storage solutions are a key component of hybrid renewable infrastructures, combining reliability, scalability and proven field performance. We specialize in molten salt systems, high-temperature steam cycles and integrated control architectures, all designed to maximize efficiency and extend energy availability.

Participation in CSP projects exceeding 2,000 MWe, including plants with molten salt storage systems deployed

Sener has developed proprietary thermal storage systems in landmark solar thermal projects such as Gemasolar (Spain), Kathu (South Africa) and NOORo III (Morocco).

We deliver thermal storage solutions that boost plant flexibility, performance and sustainability

Our systems reduce curtailment, stabilize grids and lower LCOE, making renewable energy more viable in both utility-scale and behind-the-meter applications. We design for durability, safety and operational efficiency under a wide range of operating conditions.

Why choose us

We design and implement thermal storage systems adapted to CSP, industrial heat processes and hybrid renewable plants. Our molten salt technology is the result of years of in-house R&D, focused on high energy density, thermal stability and long-duration discharge. We also integrate thermal storage with energy management systems (EMS), enabling smart control, load balancing and performance optimization.

How we work

We provide a full range of services: from conceptual engineering and feasibility studies to detailed design, commissioning and asset monitoring. Our team works closely with solar developers, utilities and industrial partners to integrate thermal storage into new or existing infrastructures. We simulate thermal behavior, assess material compatibility and implement control strategies tailored to each project’s energy profile and operating logic.

We create and integrate thermal storage from concept to commissioning

Thanks to our proprietary models and simulation tools, we adapt each solution to specific energy loads, renewable generation curves and dispatch profiles — ensuring both economic and technical performance across the system lifecycle.

Experience in thermal storage worldwide

Sener has developed thermal storage solutions linked to CSP plants and hybrid systems, combining engineering, MEP and safety expertise to ensure performance and sustainability.
