NEDO Interview

Initiatives in the Area of Smart Communities Since around the year 2000, NEDO has been developing grid interconnection technologies to deal with the large-scale connection of power generated from sources such as solar and wind as well as conducting demonstration projects, and our efforts to expand their practical use have advanced. Building upon our knowledge and experience, we are conducting our demonstration projects with the aim of realizing “smart communities” that use not only electricity but also heat as an energy source, and can share information with the consumer side and the transportation system, and improve efficiency and optimize overall local energy supply and demand. We spoke with NEDO Smart Community Department Director General Masaaki Yamamoto about the current situation and progress in this area.

Maximizing the Use of Renewable Energy In December of 2013, in order to provide a stable supply of electricity and reduce environmental impacts, a demonstration project to make efficient use of renewable energy and overcome issues including supply and demand fluctuations and load on the power grid by utilizing the storage capacity of electric vehicles was launched on the island of Maui in Hawaii, where the transition to renewable energy has been advancing.

Absorbing fluctuations in wind and solar power through electric vehicle storage capacity The introduction of renewable energy production such as wind and solar power generation has been increasing in the state of Hawaii, and there is a plan to meet over 40% of electricity demand through renewable energy by 2030. Underlying this are concerns about the adverse effects on the environment of heavy dependence on fossil fuels and rising fuel costs due to transportation cost increases that are a specific challenge for

In addition, we are trying to optimize the balance of electric supply and demand on the island by instantly interrupting charging in situations where the power supply is insufficient, such as when wind power generation stops unexpectedly. Interest among the public is very high. By May 2014, 300 individuals had volunteered their own EVs and expressed interest in participating. Based on our upcoming analysis and review results, we would like to expand this system that can help to achieve a low-carbon society on islands and subtropical regions that have an environment similar to Maui’s. 8

Supporting the Improvement of Global Energy Efficiency and the Diversification of Energy Sources

Project Formation Research on High-Efficiency Coal Utilization Systems NEDO has started the “Project Formation Research on High-Efficiency Coal Utilization Systems” to promote the export of infrastructure from Japan. In order to export Japan’s technologies related to highly efficient use of coal to overseas, NEDO is conducting the “Project Formation Research on HighEfficiency Coal Utilization Systems.” This is in line with an infrastructure export strategy by the Japanese government, which sets an export sales target for 2020 at 30 trillion yen, three times as much as the current export sales of 10 trillion yen. This export sales target includes 9 trillion yen from energy field. NEDO began this project in 2011. Specifically, a feasibility study has been conducted in order to advance the overseas expansion of highefficiency coal utilization systems that include Japan’s high-efficiency power generation technology, carbon dioxide capture and storage (CCS) technology and operation management technology. Through the study we are examining each country’s energy efficiency and market conditions to expand systems matched to country-specific issues. For example, Japanese technology would enable a country to make use of unused low rank coal in ways that are highly efficient and environmentally-friendly. Combustion tests and other tests for partner countries to show how they can properly make use of coal can be used as effective promoting tools for Japan’s advanced technological achievements.

Overseas dissemination of NEDO’s high-efficiency CCT technology (2012 results) Our goal is to improve the energy efficiency and support the diversification of energy sources in partner countries while at the same time strengthening the global competitiveness of Japan and contributing to solving global environmental problems.

Since NEDO is a governmental agency it seems that the level of trust from partner country representatives is high. 32 research projects have been conducted in 19 countries by 2013. Since partner country representatives understand the high level of the Japanese technology, we anticipate that, while we do not predict immediate agreements, projects with signed agreements will emerge in the near future. We have high hopes because if all of the project formulation research of the past two years reaches project

implementation stage, we can achieve reductions of roughly 1,500 tons of CO2 emissions. If coal-fired power plant construction goes forward, the scale of investment may reach the 100 billion yen mark, and this holds major significance for Japanese industry if they are selected to participate in the project. The “Project Formation Research on High-Efficiency Coal Utilization Systems” will serve as a part of infrastructure system export strategies and has the ability to make great contributions to both developing the Japanese economic growth and reducing CO2.

Research project objective: Dissemination of Japanese Clean Coal Technology 1. Promote a project by Japanese entities in areas where it is difficult for private entities to develop the project on their own. 2. Conduct activities to gain understanding and cooperation about the high level and efficacy of Japanese technology from partner countries and the management teams of partner companies through result reporting, policy discussions and bilateral meetings. 3. In addition to the research studies, provide assistance for testing processes to verify possible applications of Japanese technologies in partner countries (combustion technology, furnaces, gasification, etc.).

NEDO and UK Government Concludes MOU for Smart Community Project in Manchester

NEDO concluded on March 12, 2014 a memorandum of understanding (MOU) with the Department for Business Innovation & Skills (BIS), the Department of Energy and Climate Change (DECC) of the British government and the Greater Manchester Combined Authority (GMCA) to conduct a smart community demonstration project in Manchester leveraging Japan's heat pump technology and Information and Communication Technology (ICT). NEDO Chairman Furukawa, at the MOU signing ceremony in the presence of Mr. Hayashi, Japan's ambassador to the United Kingdom in the Houses of Parliament, stated that this unprecedented demonstrative project that would aggregate residential negawatt (conserved electricity by the demand side) to trade in the power market could play a significant role in making a shift of the principal source of energy from gas to electricity as well as in establishing a low-carbon society in England, drawing a number of lessons Japan could learn at the same time and contributing to the advancement of economic and technological exchange between Japan and England through the dissemination of the state-of-the-art smart technology.
