Panasonic Corporation is making strides in sustainable manufacturing by implementing a demonstration project at its microwave oven manufacturing plant in Cardiff, Wales. The project integrates renewable energy sources like hydrogen fuel cells, solar power, and storage batteries to power the facility. With the installation of 21 units of 5-kW hydrogen fuel cell generators, alongside photovoltaic generators and storage batteries, Panasonic aims to achieve 100% renewable energy supply for its operations. The company plans to use green hydrogen produced in the UK, classified as 'green' due to its production using electrolyzers powered by carbon-free sources. By utilizing excess heat from the fuel cell generators for heating and hot water, Panasonic is not only reducing CO2 emissions but also maximizing energy efficiency. The project also includes the establishment of an energy management system to monitor electricity demand and weather changes. This initiative aligns with Panasonic's environmental vision to achieve net-zero CO2 emissions by 2030 and reduce global CO2 emissions by more than 300 million tons by 2050. Through these efforts, Panasonic is showcasing its commitment to sustainability and innovation in the manufacturing sector.
