Concentrated solar power plants (CSP) use high amounts of direct beam irradiation to efficiently produce heat (and electricity, after that heat is fed into a turbine). Parabolic trough collectors (Figure 1) are a highly popular CSP technology and a type of concentrated solar collectors that use receiving mirrors curved in a parabolic shape along their […]

Types of Sensible Thermal Energy Storage for Industry: Which One Fits Your Facility? 1. What Are We Talking About (and What Is Outside the Scope)? Thermal Energy Storage (TES) is becoming an increasingly common component of solar thermal energy systems for industry. By making it possible to store heat generated during periods of high solar […]

Why Talk About CAEs Now? The energy sector is entering an important deployment phase. Energy efficiency and fossil fuel reduction technologies are being applied in industrial environments with measurable results. The next step is to facilitate the implementation of these projects. Energy Saving Certificates (CAEs) introduce an additional variable into decision-making by assigning a direct […]

HCE Supply for CSP Plants Over the past year, FersiSolar structured and executed its first Huiyin Receivers (HCEs) supply project for a CSP plant. That first operation marked the beginning of a line of work that has since been consolidated through new technical assessments, economic analyses, and discussions with operators facing similar challenges in their […]

Following the successful completion of yet another project, FersiSolar once again demonstrates what consistent solar field expertise looks like when applied to real operating conditions – translated into delivered results.  Project Context and Scope of Services  The project addressed a familiar but critical challenge in large solar thermal plants: the gap between expected performance under theoretical design conditions and actual performance under real‑world operation. While the plant was […]

El sector energético está experimentando su mayor transformación. Conceptos que antes eran técnicos, como “descarbonización” o “servicios energéticos”, hoy están en el centro de las estrategias de cualquier empresa competitiva. Por eso, hemos dado un gran paso en la Asociación Nacional de Empresas de Servicios Energéticos (ANESE). ¿Qué son los Servicios Energéticos y cómo funcionan? […]

We recently completed an exhaustive inspection and technical evaluation campaign at a Concentrating Solar Power (CSP) plant, specifically focusing on the Heat Collecting Elements (HCEs), or receivers. These components are, without a doubt, the core of the Parabolic Trough Collector (PTC) technology, and their performance defines the economic and operational efficiency of the entire power […]

The decarbonization of industry represents one of the major challenges of the energy transition. Heat is at the heart of this challenge: two-thirds of annual energy consumption in industries in the European Union is used for process heat. At present, the vast majority of this consumption is supplied by fossil fuels, with natural gas playing […]

Over the last weekend, FersiSolar joined the program of the annual conference of SolarPACES, the leading technology collaboration programme of the International Energy Agency (IEA) on concentrated solar power technology (CSP). In this year’s edition, the conference included a tour of the Andasol 3 solar thermal power plant, which is operated by Marquesado Solar. As […]

In Fall 2025, FersiSolar has successfully managed the first order of Huiyin receivers (Heat Collection Elements, HCEs) for a concentrated solar power plant. This is a major achievement for the Spanish company, which is committed to concentrated solar thermal energy and technical advisory services for CSP projects worldwide. Replacing damaged HCEs improves plant productivity, extends […]

The production of gypsum requires a constant heat supply to ensure product quality and process efficiency. Concentrated solar thermal energy with thermal energy storage offers an alternative to gas for industrial processes in the minerals sector. With this technology, it is possible to generate hot air and reach temperatures of up to 400°C, achieving 78 […]

La integración de energía solar como fuente de calor industrial en una planta de manufactura de pinturas representa una solución viable para avanzar hacia una industria de pintura con cero emisiones. En este proyecto estudiamos la viabilidad de implementar un campo solar térmico capaz de suministrar aire caliente industrial con energía solar a 200ºC, cubriendo […]

We have often discussed the importance of decarbonizing process heat in industry and argued that concentrated solar thermal energy could play an important role in this. But how are fossil fuels actually replaced in practical terms? In this text, we dive into the topic. Above is the schematic that will guide us. We will focus […]

Wouldn’t it be amazing to live in a more just and equal society where extreme poverty and hunger are a thing of the past? A future in which our species is not exploiting its environment to the point of tipping the whole planet off balance? The energy transition should be and could be a step […]

Tanques de almacenamiento en construcción en Hungría. Fuente En la publicación anterior, hablamos mucho sobre el almacenamiento de calor en las industrias. Establecimos los fundamentos de la tecnología, su nivel de madurez y su impacto ambiental. Pero en ningún momento discutimos de cómo se usan estos sistemas en la práctica, lo cual quizás sea la […]

El almacenamiento térmico en la industria puede generar tanto a un ahorro energético considerable, como a la descarbonización de la energía que consumen las industrias – dos pilares clave de la transición energética. A pesar de todo esto, la mayoría de las personas piensa solo en el almacenamiento de electricidad que sí que tiene un […]

Cover image: Redstone power plant in South Africa. Source How can we make solar power at night? Solar PV is extremely successful at generating solar power during daytime. However, once the sun sets the grid needs to rely on more expensive nuclear, geographically limited hydro or polluting gas and coal. If we want to use […]

Solar energy for industrial processes Or how to reduce CO2 emissions in industry The decarbonization of industrial heat is an important challenge on the path toward reducing emissions in industry. 32% of global energy consumption is used in industry, and 74% of this energy consumption is used for heat production, according to the International Energy […]
