research benefits public? Institute of Sustainable Science International Symposium on Global Sustainability － As an example, economical ｅｆｆｅｃｔ of the Fusion research is analyzed － energy sales is not the only outcome of the research. →economical effect out of the market. ”Externality” is important;. － “Impact pathway” shows 4 effects of the fusion R&D. 1) The direct effect of the purchase ; The increase of Gross Domestic Production (GDP) as a measure. Input-Output table is usually used .
2) The growth of local community and its economy. Secondary and further effect of purchase. Employment. Some of these effects can be estimated with local community effect out of input-output table. Evaluation procedure is established.3) Improvement of technical capability of the industry Technical spin-offs as part of Externality. Results usually appears slow and occasional. Not obtained from the market. Contribution.4) Energy and related technology. Appears decades later. Contribution of industry is mach larger than Original R&D. Contribution to the global environment problem.

Technical spin-offs International Symposium on Global Sustainability Institute of Sustainable ScienceThe spin-off technology is studied with actual fusion R&D projectperformed in the Japan Atomic Energy Research Institute.Total 66 billion Yen (inflation corrected) was spent in 40years.Products were identified (ca180)by the researchers and industry.Then their market sizes were evaluated by a third party(business consulting institute).Impact on the market is estimated to be 2.7x109 Yen.Contribution of research institute is 1.2x108 Yen.
Future Energy Market International Symposium on Global Sustainability Institute of Sustainable ScienceMarket under environmental constraintFuture energy mix was analyzed to consider the entire market.Environmental constraint requires reduced carbon dioxideemission.Fusion will not have chance in “business as usual” scenario.Fusion electricity is estimated to have ca. 30% of global market.It is possible to supply same amount of electricity without fusion.Difference of total electricity cost corresponds a benefit of fusion.While reduction of the expense benefits consumerReduction of the electricity cost can lead to loss in GDP. This methodology can be used for any energy
Energy supply without fusion Institute of Sustainable Science International Symposium on Global Sustainability・Future energy market is analyzed to fill the demand with minimal cost.・Fusion will not appear in “Business as usual” scenario.・Market can be filled without fusion. actual estimated Gton oil equivalent/year 30 Renewable hydrogen renewables 20 hydro nuclearUnconventional gas gas 10 Unconventional oil oil coal 0 1900 1950 2000 2050 2100 year

Fusion market analysis International Symposium on Global Sustainability Institute of Sustainable ScienceIn the sales value of electricity, 35% is generation cost.Contribution of the research is evaluated according to the currentJapanese electricity market. Fusion reactor and accompanied plant are the product of theresearch. Fusion specific devices have global export market.(on the other hand fission reactor is assumed to have difficulty inglobal market because of nuclear proliferation, fuel cycle andsocial acceptance)For the long period up to 2100, 2% discount rate was applied. - reduces to 10% as present value equivalent.
Supply chain of energy Institute of Sustainable Science International Symposium on Global Sustainability Social demand requirements resource waste Fuel Energy Waste supply Technology management flow Large quantity stock Energy externality Cheap price production Logistics inevitableDifference from LCA：dynamic. Not the estimation of inventory →constraints may occur with ample resource →constraints without material, by externality →market growth can be also limited.

Influence to the power grid International Symposium on Global Sustainability Institute of Sustainable Science The grid capacity of 10-20GW is required to supply startup power of regular size fusion reactor. The influence also depends on the grid configuration, as response time of each power station is different. Response speed Hydro fast 10%/min Oil 5%/min Coal slow 1%/min Nuclear not allowed now Solar/Wind No responseFusion requires large power Can small grid respond?

These 3 stages sometimes overwrap.• In each stages selection criteria and stakeholder are different. Technical-researchers Socialーgovernment, society,public commercialーbusiness, company Technical feasibility consumer Technical success Researcher• Due to the difference in institute Social feasibility criteria, winners could be Social value Government different.
