「In FY2019, the technology was selected for demonstration under the Ministry of the Environment’s Environmental Technology Verification (ETV) program and was demonstrated. As a result, it significantly exceeded the target performance values of the comparison technologies and obtained ETV certification as a verified technology.」
The geothermal technology was demonstrated under the ETV program and progressed to certification as a verified technology. It has advanced from the research and demonstration stages to the certification stage leading to wider adoption. - FY2019AdvancedAnnual report
「In September 2014, as part of efforts to commercialize this research technology, the project was selected for the FY2014 Renewable Energy Heat Utilization Technology Development Program solicited by the New Energy and Industrial Technology Development Organization (NEDO), then an incorporated administrative agency, and the Company conducted five years of joint research. Subsequently, in August 2018, it implemented a cascade type that combines conventional open-loop technology, with the aim of expanding the scope of applications for the technology developed through the five-year joint research. In February 2019, based on performance data from the initial stage of the cascade type, the technology was selected by the Ministry of the Environment as a technology for demonstration under its FY2019 Environmental Technology Verification (ETV) program. The Company plans to obtain certification as a verified technology.」
The Company completed five years of joint research with NEDO and implemented the cascade type in August 2018. It was also selected as a technology for demonstration under the FY2019 ETV program and plans to obtain certification as a verified technology. - FY2018RestatedAnnual report
「The five-year development period for the joint research runs through 2018. Following the construction and operation of a demonstration plant and verification of its various performance characteristics, the Company plans to commercialize the technology.」
The Company continues to disclose its joint research with NEDO, development period through 2018, verification using a demonstration plant and patent acquisition. - FY2017AdvancedAnnual report
「The five-year development period for the joint research runs through 2018. Following the construction and operation of a demonstration plant and verification of its various performance characteristics, the Company plans to commercialize the technology. The research and development resulted in Patent No. 5963790, “Groundwater-circulation geothermal heat extraction system and geothermal heating, cooling or hot-water supply system,” granted on 8 July 2016.」
