Albufera Energy Storage, established in 2013 in Madrid, Spain, specializes in developing and commercializing advanced aluminum-based battery solutions. The company stands out for its innovative approach to energy storage, holding three patents in aluminum battery technology. Their work focuses on creating sustainable, efficient, and cost-effective energy storage solutions while providing expert consulting services and training. The company’s mission centers on addressing critical challenges in energy storage through aluminum-based technologies, which offer improved safety features and environmental benefits compared to traditional battery types.
The company maintains its primary operations through its subsidiary, Albufera Integration, which began operations in southern Madrid in 2019. This division handles product supply, battery sizing for large installations, training programs, and engineering services. Their integrated approach to battery technology development and commercialization positions them as a significant contributor to sustainable energy storage solutions in the European market.
Battery Technology
Albufera Energy Storage’s primary focus lies in three distinct aluminum battery technologies:
- The aluminum-ion batteries developed by the company achieve specific energy values of up to 80 Wh/kg, surpassing traditional nickel-cadmium and lead-acid batteries. These units demonstrate exceptional durability with over 6,000 charge-discharge cycles and maintain efficiency rates of 90% or higher. The technology operates effectively across temperatures ranging from 0°C to 50°C without capacity loss.
- Their aluminum-air batteries represent a significant advancement in electric mobility applications. By utilizing atmospheric oxygen as an active material, these batteries reduce overall system weight and cost. The technology has demonstrated impressive specific energy values of 2,140 Wh/kg in material test cells, with ongoing development aimed at achieving 1,000 Wh/kg in vehicle prototypes by 2025.
- The company’s aluminum-solid state batteries incorporate high-viscosity gel or solid electrolytes, making them particularly suitable for portable electronic equipment. These batteries excel in applications requiring longer charge-discharge cycles, typically over five hours, and offer enhanced safety features compared to liquid electrolyte alternatives.
Recent Projects
Through 2024, Albufera Energy Storage has advanced several significant initiatives. The company has focused on developing rechargeable aluminum-air batteries under the NEOTEC program, which involves material characterization, component integration, and cell testing. They have also made progress in creating high-efficiency cathodes for metal-air rechargeable batteries and developing a sulfur-aluminum battery featuring advanced polymeric gel electrolytes. These projects receive support from various national and international funding sources, including the European Union’s H2020-FETOPEN program.
