I developed a detailed energy technology model using TIMES, which is also widely used by IEA, the British government, and the EU. TIMES simulates the combination of technologies which give the highest cost-performance within an energy system. i.e., it calculates the optimal technological combination for an ideal society. I referred to “NEDO Fuel Cell & Hydrogen Technology Development Road Map”, “Hydrogen Road Map”, IEA-ETSAP Energy Technology Database, and other academic journals for information on the current state and future of hydrogen technologies. Goals of the model: 1. Market forecasting: merits of entering a market; resiliency of business model 2. 3. 4. Investment strategy: infrastructure investment in pipelines, connector lines R&D strategy: what are goals of R&D (performance or cost)? Policy evaluation: how big will a given market become given current policies? 16 Copyright 2015 FUJITSU RESEACH INSTITUTE Prefecture Level Resolution • Detail energy system by prefecture • Reflect regional characteristics Coal LNG Oil Sankey 17 Copyright 2015 FUJITSU RESEACH INSTITUTE Energy Demand Curve By inputting actual energy consumption patterns, we see variance by time of day and season.

Concluding Remarks To maximise renewables, the FIT premiums will decrease to 40% of 2015 level in 2030. Under these assumptions, biomass electricity market is expected to be 1.44billion US$ in 2030. To avoid instability in the electricity system due to the increase of intermittent renewables, Japanese government is aiming for 3.7-4.6% biomass electricity in 2030, but under current policies the share will be 2.2% in 2030. Japanese government should/will implement the following policy measures: Make biomass competitive against other renewables by differentiating FIT price Control the introduction of wind turbines through FIT price adjustment and/or upper limits on introduction into system. Expand biomass financial support. Make biomass-generated heat subject to FIT. 41 Copyright 2015 FUJITSU RESEACH INSTITUTE Some difficulties biomass faces To use subsidies from Japanese government, mainly Japanese companies products are employed. Japanese companies electricity generator is too big capacity. • Several hundreds MW Japanese customers tend to introduce too big capacity compared to the supply of biomass. Japanese government is thinking about to introduce carbon emission/energy efficiency regulation to coal power station( etc. CO2 emission/kWh) After the earthquake, coal played some role to offset the shortage of electricity supply. Biomass might be used to decrease the carbon intensities of coal power station. As a result, biomass price will increase sharply which makes biomass only power station become less competitive. 42 Copyright 2015 FUJITSU RESEACH INSTITUTE Biomass 2 Hydrogen (Fukuoka-city) Offsite Hydrogen Station Onsite Hydrogen Station Greenhouse Sewage Treatment Back-up Power Source: Fukuoka City 43 Copyright 2015 FUJITSU RESEACH INSTITUTE Copyright 2015 FUJITSU RESEACH INSTITUTE 44
