In March 2008, Japan’s Ministry of Economy, Trade and Industry established its “Cool Earth-Innovative Energy Technology Program” as a long-term objective to halve current global greenhouse gas levels by 2050. The program includes a roadmap that lists
technological fields that Japan should prioritize to achieve these reductions. The roadmap includes heat pump technology, but there are concerns that it will be difficult to meet efficiency goals outlined in the roadmap through heat pump development only. Therefore, NEDO has given careful consideration to not only individual elemental technology development but also heat pump system development through its efforts in diverse areas
such as heat source utilization, and construction/installation sites. In 2010, NEDO implemented the Research Project on Next-generation Heat Pump Systems aimed at developing innovative heat pump systems that have high-efficiency operability and meet user demands. The focus of this paper is to provide an overview of energy consumption in Japan
and NEDO’S efforts in addressing energy consumption challenges through heat pump development.
