Panasonic has successfully implemented a groundbreaking renewable energy project at its factory in Cardiff, Wales, in the United Kingdom. The project involves the integration of solar power, hydrogen fuel cell generators, and storage batteries to power the factory that produces microwave ovens using 100% renewable energy sources. The company has installed 21 units of 5 kW pure hydrogen fuel cell generators as part of a distributed system optimized for the factory's electricity demand. By combining these generators with photovoltaic systems and storage batteries, Panasonic aims to efficiently generate and store only the necessary electricity on-site. A key component of the project is Panasonic's energy management system (EMS), which will monitor changes in electricity demand and weather patterns to ensure a stable supply of renewable energy to the factory. The EMS is set to begin operation by March 2025. Furthermore, the integrated control of 21 pure hydrogen fuel cell generators will not only improve maintainability and operational efficiency but also contribute to the decarbonization of electricity used in the factory. By utilizing green hydrogen produced in the UK, Panasonic hopes to showcase the potential of hydrogen technologies and accelerate innovation in the industry. The project also focuses on utilizing the heat generated during electricity production for heating and hot water in the factory, achieving high energy efficiency and promoting a hydrogen society. With a vision for a decarbonized future, Panasonic aims for the facility to serve as a hub for fostering partnerships, technological advancements, and industry growth in the UK's hydrogen sector.
