Examples of NEDO‘s R&D technologies in Energy ConservationToday, I would like to introduce NEDO’s energy conservation projects in the commercial, transport and industrial sectors.Let me begin with by giving an overview of Japan’s energy consumption.
3 1. Trends of Energy Consumptions in Japan Japan’s Energy Conservation Trends First of all, I would like to give some background information on energy conservation in Japan. This slide shows changes in Japan’s primary energy consumption per GDP.We have steadily improved our economy’s efficiency for almost forty years as the indicator here shows. However, there still is a problem regarding Japan’s energy consumption.The problem is the total amount of gross consumption we can see in the next slide.Source: Development of Energy Conservation Policy, Law and Management Concept in Japan (Akira Ishihara, ECCJ)
4 Japan’s Energy Consumption Trends Final energy consumption has increased about 1.3 times since 1973, whereas real GDP increased about 2.4 times in the same period.Industrial sector energy consumption has leveled off, but a significant increase in energy consumption has been observed in the consumer sector (commercial and residential subsectors).(Petroleum equivalent in million tons)(JPY trillion)Real GDP1973→20112.4 timesFinal energyconsumption1973→20111.3 timesTransportation1.9 timesConsumer2.5 timesIndustrial0.9 times23.3%Transportation sectorConsumer sector33.8%Energy consumption in Japan can be divided into three groups: the industrial sector, the transport sector, and the consumer sector.Energy consumption in the consumer sector has been increasing significantly, and it accounts for 33.8 percent of total energy consumption.Consequently, reducing the use of energy in this sector continues to be a key issue.Industrial sector42.8%Source: Comprehensive Energy Statistics and Annual Report on National Accounts
5 Energy Policy for Promoting Energy Conservation in Japan IndustrialsectorTransport sectorCommercial subsectorResidential subsectorRegulationEnergy Conservation LawTop Runner Program of Energy Conservation LawSupportPromotion of products with a high levelof energy conservation performance(via tax system, funding and loans)Promotion of R&D for innovative energy conservation technologyPromotion of high energy efficient consumption equipment for supplying hot water and air conditioningNext, I’d like to explain about Japanese Regulation and Supports.There are regulations and support measures for the promotion of energy conservation in the industrial and transport sectors and commercial and residential subsectors.The Energy Conservation Law covers all sectors.The Top Runner Program is based on the Energy Conservation Law. It regulates all sectors except the industrial sector in order to promote energy efficiency.The Energy Conservation Law prescribes energy efficiency standards for appliances and vehicles corresponding to those of the Top Runner Program.The concept of the Top Runner Program is that standards are set higher than the best performance value for each product on the market. Standard setting takes into account technological development.NEDO supports the promotion of research and development for innovative energy conservation technology, and also supports the promotion of high energy consumption efficiency equipment for the commercial subsector.
6 Outline of 2011 Strategy for Energy Efficiency Technologies ObjectivesIn order to achieve goals for 2030 included in the Basic Energy Plan, the 2011 Strategy for Energy Efficiency Technologies aims to develop energy efficiency technologies, promote the introduction and international deployment of such technologies, serve as a guideline for stimulating economic growth and realize Japan’s aspiration to be the world’s leading nation in terms of energy efficiency technologies.This strategy therefore prioritizes wide-ranging energy efficiency technologies and selects key technologies that can meaningfully contribute to Japan’s energy-saving efforts.Key technologiesIndustrial sectorResidential/Commercial subsectorsTransport sectorCross-sectorTechnologies to minimize exergy lossTechnologies to improve system energy efficiencyTechnologies to manufacture energy-saving products ZEB and ZEH Energy-saving information devices and systemsEnergy efficiency technologies to suit personal preferencesStationary fuel cells Next-generation vehiclesITSIntelligent logistics system Next-generation heat pump systemsPower electronicsNext-generation heat and power networks Next, let me introduce NEDO’s activities in the energy efficiency technology area.At present, due to the Great East Japan Earthquake in 2011, promotion of energy efficiency technologies has been prioritized along with the introduction of renewable energy.Under these circumstances, NEDO is working to undertake various energy efficient technology development projects in the industrial sector, residential/commercial subsectors, transport sector and cross-sector.This slide shows an outline of the Japan’s strategy for energy efficiency technologies.As you can see, energy efficiency technology covers a wide range of technologies.In order to promote the Japanese government’s policy toward the future and to achieve its goals, NEDO developed the 2011 Strategy for Energy Efficiency Technologies together with the Ministry of Economy, Trade and Industry and prominent experts in the energy efficiency area.The strategy prioritizes a wide range of energy efficiency technologies and focuses on key technologies that can meaningfully contribute to Japan’s energy-saving efforts.From these key technologies, heat pumps, net-zero energy buildings (ZEB) and intelligent transport systems (ITS) were selected for further promotion.

The technology development of such power equipment for early practical application and industrial adoption is expected to greatly contribute to building an even more stable and efficient power supply system that can provide the power that is essential for economic growth.Research and development activities were divided into four themes: superconducting magnetic energy storage systems, or SMES; superconducting transformers; superconducting cable; and yttrium-based superconductor.Coated conductors for mass-production (10-20km)Preliminarywork forapplications

Multiple systems can be installed in response to load changes.◎ Air compressors using the same system have also beendeveloped.Micro Screw Expander Steam GeneratorThis slide shows an example of a Strategic Innovation Program for Energy Efficiency Technologies project. The project was carried out to develop a small once-through boiler power generation system.NEDO entrusted its work related to this project to Kobe Steel Limited. Preparatory research and research for practical application were carried out from 2001 to 2003 and from 2004 to 2006 respectively.Steam is used for various purposes at factories and other facilities. Steam used in manufacturing processes is normally depressurized to appropriate pressure levels by pressure reducing valves. However, pressure energy released in the depressurizing process is not utilized.Steam generators are attracting attention as an effective way to recycle pressure energy.Kobe Steel Limited started preparatory research in 2001 and research for practical application in 2004.Through NEDO’s project, a micro screw expander steam generator named “Steam Star” was put on the market in June 2007.This generator uses steam produced from a small once-through boiler to generate electricity, a process which was thought to be difficult to put into practice.Steam Star has received many awards, and 76 units were in operation as of September 2012.

However, pressure energy released in the depressurizing process is not utilized. As a result, steam generators have been developed to generate electricity by effectively recycling the untapped pressure energy.The steam generators are equipped with screws that can rotate by a small amount of low-pressure steam.A maximum power output of 160 kW has been achieved from steam at about 10 atmospheres.Background and technology overview● Steam is depressurized to appropriate pressure levels by pressure reducing valves in order to be used in manufacturing processes such as heating, distilling, drying and sterilizing.
