【Propane Sangyo Shimbun】”Reliable Evidence” At a Briefing session on Environmental Technology Demonstration Project

2020/03/04

The environmental technology demonstration project (ETV project) small and medium-sized hydropower technology classification project briefing session for the first year of the Reiwa was held on February 26 at the Mini Hydropower Development Support Association in Toshima-ku, Tokyo. This briefing session is mainly aimed at users, including those who are considering the introduction of so-called micro hydropower technology with an output of less than 50 kW, and manufacturers / developers who are working on similar technologies. The Environmental Technology Demonstration Project allows a third party to objectively demonstrate the environmental conservation effects, secondary environmental impacts, and other important performance from an environmental point of view for advanced environmental technologies that have already been put into practical use. , When purchasing or introducing environmental technology, it is possible to easily compare and examine environmental conservation effects and make appropriate selections. The purpose of this is to promote the spread of environmental technology, to protect the environment and to develop the environmental industry. In the first year of Oriwa, the Mini Hydropower Development Support Association was selected as a demonstration organization for the small and medium-sized hydropower technology category, and from the standpoint of a reliable third-party organization that is neither an environmental technology developer nor a user, environmental technology environmental conservation effects, etc. Plays the role of showing objective data based on tests and the like.
This time, Jun Kuwahara, CEO of ELIS (Okayama City), explained the case of the company's breast shot water wheel, which was demonstrated for manufacturers and developers in 2016. The target of the demonstration was the Takao ELIS Power Station in Niimi City, which started operation in March 2014. The basic specifications are a waterway head of about 1.3 m, a maximum flow rate of about 0.8 m3 / s, and a rated output of 7.5 m3. The diameter of the turbine is about 3m and the width of the turbine is 1.3m.
Kuwahara said, "The rated output of 7.5kW is by no means large, but the advantage is that it can be operated stably by installing it in a waterway with a stable flow rate throughout the year. The operating efficiency is higher than that of solar power generation." After explaining this demonstration, "We were always able to obtain data on electric power, but the merit of the ETV business was that we were able to obtain an objective evaluation of the flow rate and noise. In addition, this result led to better research and development. Reliable evidence was obtained, and the plus was great. " (Excerpt)
