Bluesolar Technologies, founded in 2019, is a Spanish company that developed a hybrid solar technology combining photovoltaics (PV) and concentrated solar power (CSP) to provide continuous, dispatchable renewable energy. The firm’s management and founders, including CEO Sebastián Caparrós and Director José Julio Caparrós, possess extensive experience in renewables and engineering. The technology was co-developed with Ghenova Ingeniería and in collaboration with numerous Spanish and European research centers like CSIC and Fraunhofer. The company’s core product is a hybrid panel that integrates a patented optical light-selective filter into a standard PV panel. This filter transmits the most efficient light wavelengths for electricity generation to the PV cells while reflecting the remaining energy (infrared and blue wavelengths) to a central tower receiver. This reflected energy heats molten salts, a mature thermal storage technology, which can then be used to generate electricity via a turbine or provide heat for industrial processes, even at night. This dual-generation system increases the overall energy efficiency by up to 50% compared to a standard PV panel. Bluesolar Technologies addresses the energy industry’s challenges of energy storage, industrial decarbonization, and green hydrogen production. Its B2B model focuses on being a technological partner for new greenfield developments and retrofitting existing PV plants to convert them into baseload generators. The company targets two main markets: dispatchable renewable electricity generation and providing a heat source for industrial processes, desalination, and behind-the-meter hydrogen production. In November 2024, the company inaugurated its first pilot plant, BlueSolar1, in Puertollano, Spain, a project co-funded by CDTI and the Andalusian Technological Corporation (CTA).
