Japanese energy supplier, Akasaka Heating & Cooling Supply, is pioneering the use of green hydrogen to power its district heating system in central Tokyo. By leveraging green hydrogen produced at an undisclosed location in Japan, the company aims to reduce CO2 emissions in its energy production process. The initiative involves sourcing green hydrogen, storing it in specialized hydrogen storage alloy tanks, and utilizing it to generate heat and electricity through Panasonic fuel cell systems. These fuel cells will provide power for various applications within the district, promoting energy efficiency. Additionally, the company plans to blend the remaining green hydrogen with natural gas for use in hydrogen-mixing combustion boilers, further optimizing energy utilization. This innovative approach not only ensures a more sustainable energy supply but also emphasizes safety by using non-hazardous storage alloys that reduce the hydrogen volume and operate at low pressure levels. With the integration of green hydrogen technology, Akasaka Heating & Cooling Supply sets a precedent for eco-friendly energy solutions in urban settings, marking a significant step towards a greener and more efficient energy future.
