International Demonstration Project on Japan's Technologies for Decarbonization and Energy Transition

Project overview

Project period: starting in FY1993, FY2023 budget: JPY6.5 billion (for international demonstration projects)

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 Project on Japan's Technologies for Decarbonization and Energy Transition

(1) Intended Technologies for Demonstrations

Twelve technical fields

Observation and stabilization technologies for electric grid systems
Constructing distributed energy systems and technologies contributing to improvement of accommodation capabilities
Excess electrical energy transforming technologies
Technologies contributing to electrified area extension
Low-cost hydrogen technologies (manufacturing, transportation and storage, and utilization)
Carbon recycling-related technologies expected to offer reduction and substitution effects, such as methanation and so on
Sustainable bio-fuel or synthetic fuel manufacturing technologies
Smart city-related technologies using big data, AI, dispersion management technology
Technologies contributing to transformation and decarbonization in the transportation industry
Energy efficiency technologies leveraging IoT and AI in industries, business operation, and households
Not conventional but advanced renewable energy technologies
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).
