Japan Gastech Consortium Chairman Nobuo Tanaka expects Gastech Japan 2017 to be a milestone for power suppliers and users to come to a consensus on the role of gas in the energy mix of the future.

Gastech Japan 2017, the world's largest event for the gas industry, will be held at Makuhari Messe, in Chiba Prefecture, from Tuesday to Friday. It is expected that 25,000 visitors from all over the world will attend the exhibition that features 600 exhibitors and more than 200 speakers.

"Gas is a clean energy source. Its availability will improve and investment will also be increasing," Tanaka, the chairman of The Sasakawa Peace Foundation and the former executive director of the International Energy Agency, said in an interview in Tokyo.
