The natural refrigerant subsidy will continue to be available in the same industrial sectors: cold storage, food manufacturing, and food retail.
About Japan’s natural refrigerant subsidy scheme:
Since 2014, subsidies have been a major driver of growth in the number of CO2 stores in Japan as well as NH3/CO2 cold store facilities. The stated goal of the subsidy is to encourage the “shift to natural refrigerants […] and to widely promote the use of energy-efficient equipment”.
In the upcoming HPT Magazine issue 3/2018, there will be an article covering this development.
Japan’s Ministry of the Environment says that the subsidy aims to “contribute to driving down the cost of natural refrigerant equipment to achieve cost parity with conventional F-gas equipment, and to accelerate the spread of the technology”.
