NEDO aims to internationally disseminate Japan’s advanced technologies that can contribute to safety, energy security, economic efficiency and the environment (S+3E) by demonstrating such technologies overseas. Furthermore, international demonstrations to be carried out in energy markets with more advanced energy policies are designed for Japan to gain meaningful results for domestic use. Through these efforts, the projects aim to contribute to the spread of Japan’s energy-related industries, to energy transition and decarbonization in Japan and abroad, and to Japan’s energy security.

1. International Demonstration Projects on Japan's Energy Efficiency Technologies

(1) Intended Technologies for Demonstrations

Twelve technical fields

[1]

Observation and stabilization technologies for electric grid systems

[2]

Constructing distributed energy systems and technologies contributing to improvement of accommodation capabilities

[3]

Excess electrical energy transforming technologies

[4]

Technologies contributing to electrified area extension

[5]

Low-cost hydrogen technologies (manufacturing, transportation and storage, and utilization)

[6]

Carbon recycling-related technologies expected to offer reduction and substitution effects, such as methanation and so on

[7]

Sustainable bio-fuel or synthetic fuel manufacturing technologies

[8]

Smart city-related technologies using big data, AI, dispersion management technology

[9]

Technologies contributing to transformation and decarbonization in the transportation industry

[10]

Energy efficiency technologies leveraging IoT and AI in industries, business operation, and households

[11]

Not conventional but advanced renewable energy technologies

[12]

Other technologies contributing to energy transition and decarbonization

(2) Implementation format

Project implementation consists of the following phases: (1) surveys of the suitability of demonstration requirements; (2) pre-demonstration surveys; (3) demonstration research (demonstration projects in the case of entrustment); and (4) follow-up activities. Each series of projects is regarded as a single theme, and, after public solicitation for proposals are conducted to select implementers of phase (1) surveys, a committee of outside experts conducts reviews to decide whether to proceed from phase (1) to phase (2), and from phase (2) to phase (3). Decisions regarding whether to implement phase (4) are made separately.

Phase (1) is implemented as entrusted projects, while phase (2) and subsequent phases are generally implemented as subsidized projects (percentage paid by NEDO: 1/2 in the case of large companies or 2/3 in the case of SMEs).
