  1. Commercialization of Residential FC in Japan ～ Current status and driving forcefor the success ～ Toshiba ENE-FARM ENE-FARMis acommon brand name of a residential fuel cell system in Japan. 13, November 2013 Toshiba Fuel Cell Power Systems Corporation 1

  2. General Approach of Residential PEFC in Japan • Outline of Toshiba Activity to Residential PEFC • Summary Background of Successful Commercialization

  3. History and Plan of ENE-FARM Commercialization in Japan • After technology verification and large scale monitoring program, Japan started initial commercialization of 1kW class residential PEMFC “ENE-FARM” in FY2009. Around 50,000units are now operated in Japanese household. Large Scale Monitoring

  4. Large Scale Monitoring Program by Japanese Government In advance of commercialization, over 3,300unit of residential PEFC were installed and verified in FY2005 through 2008 under governmental program. In the program, system showed enough performance and reliability as future commercial product. The Amount of CO2 Reduction [kg/month] Five system manufacturers joined to the program, and delivered 3,307units. Toshiba delivered 748 units among them. Thermal Load of each House [MJ/month] Residential PEFC showed the performance to reduce 100kg/month of CO2 as the average. 4

  5. Status of ENEFARM Dissemination Trend of sales volume Start commercialization Another 53k for FY2013 by METI Sales started in 2009 with the declaration by government and energy companies on January, 28, 2009. The sales volume has been increased year by year. Accumulated volume is expected to be more than 40,000unit in FY2012 ［Annual volume] 2013 ［Fiscal year］ * the volume of 2012 is roughly estimated based on subsidy condition as of end of August

  8. 2nd Generation Model of Toshiba ENE-FAEM (TM1-AD) The highest energy saving “1.5ton/year” The higher total efficiency “94% Total (39%E & 55&H) High value added “GI capability w/o battery” Cost competitiveness “Leading cost reduction among Japanese ENEFARMs” Fuel diversity and its tolerance “Already delivered commercial units in Japan” The longest durability “80k hrs w/o CSA replacement” Easier installation “Lighter and smaller system” Higher maintenance capability “3.5yrs maintenance interval. Work w/o system shut down”

  9. Cost reduction approach “REDUCE” was one of core concept in accelerating the cost reduction. 30% of cost reduction was achieved with technology approach. System / Package： ・Simplify system ・Apply multimodulepiping ・Apply low cost BOP Reformer ・Optimize catalyst ・Minimize length of welding FC unit Module pipe Inverter & Controller ・High performance one integrated to single board FY2011 New CSA ・Reduce cell number (15%) ・Reduce catalyst (20%) ・Apply low cost material CSA

Successful shifting to commercialization in Toshiba PEFC • Development • >35% Electric / >85% Total Efficiency • System durability longer than 70kh • Reliability better than 5% annual failure rate • Significant CR (to 1/8 level through 5years) • Tolerant system for raw fuel (NG & LPG) • Light weight for installation (104kg) • Low noise design (<40dB) • Verification • Delivered around 800units since 2005 until 08 • The longest units recorded 30kh in real field • Total fleet operation time to be 10million hrs • CO2 reduction to be 1.2-1.4t/year • Reliability potential for commercialization 15,000 – 20,000 units in FY2013 4,200 • Commercialization readiness • Preparing production process • Maintenance and sales channel with energy companies • Getting Japanese certification 2013

  11. Business and Market Expanstion toward the future Various application offers the possibility to expand ENE-FARM market and business toward the future. • Continuous improvement of ENE-FARM as core product (cost, performance, reliability and durability and maintainability) • Offering and preparing wider application to expand the market (HEMS, expanded GI option, fuel diversity, option for colder area) HEMS、Smart grid with PV andBattery -20degC ambient
