In this study, the amount of carbon dioxide produced by hydrogen vehicles was estimated, and compared to the carbon dioxide emissions of gasoline, hybrid, electric vehicles. Although the quantity of carbon dioxide produced by electric vehicles depends on the power mix, in Japan, electric vehicle and hydrogen vehicle emissions are currently almost the same. However, by 2030, electric vehicle carbon dioxide emissions, are expected to be lower than those of hydrogen vehicles, when the power mix will reach current government targets. The government is currently promoting the use of hydrogen vehicles, but high capital investment will be required for the necessary hydrogen refueling stations. Above all, hydrogen is a very dangerous gas that can explode due to minor errors. Conversely, electric vehicles have already gained popularity and do not carry the same risks. For these reasons, it is more reasonable to promote the use of electric rather than hydrogen vehicles. Finally, this study considers the current situation and feasibility of carbon dioxide capture and storage.","subitem_description_type":"Other"}]},"item_10_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"39672","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ito, Toshihide"}]},{"nameIdentifiers":[{"nameIdentifier":"39673","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Miyazawa, Tatsuki"}]},{"nameIdentifiers":[{"nameIdentifier":"39674","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yamamoto, Kyosuke"}]}]},"item_10_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"関西大学"}]},"item_10_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10484636","subitem_source_identifier_type":"NCID"}]},"item_10_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1341156X","subitem_source_identifier_type":"ISSN"}]},"item_10_version_type_17":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"伊藤, 俊秀"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"宮澤, 樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山本, 恭輔"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-06-11"}],"displaytype":"detail","filename":"KU-1100-20200130-01.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KU-1100-20200130-01.pdf","url":"https://kansai-u.repo.nii.ac.jp/record/16093/files/KU-1100-20200130-01.pdf"},"version_id":"ac8fc539-5ffa-45a6-9f2b-d92383905b32"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"水素自動車","subitem_subject_scheme":"Other"},{"subitem_subject":"二酸化炭素","subitem_subject_scheme":"Other"},{"subitem_subject":"CCS","subitem_subject_scheme":"Other"},{"subitem_subject":"hydrogen vehicle","subitem_subject_scheme":"Other"},{"subitem_subject":"carbon dioxide","subitem_subject_scheme":"Other"},{"subitem_subject":"関西大学","subitem_subject_scheme":"Other"},{"subitem_subject":"Kansai University","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"水素自動車が排出する二酸化炭素に関する一考察 : 問われる水素社会の虚構","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"水素自動車が排出する二酸化炭素に関する一考察 : 問われる水素社会の虚構"}]},"item_type_id":"10","owner":"10","path":["2114"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-06-11"},"publish_date":"2020-06-11","publish_status":"0","recid":"16093","relation_version_is_last":true,"title":["水素自動車が排出する二酸化炭素に関する一考察 : 問われる水素社会の虚構"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2023-05-17T02:00:38.363196+00:00"}
