Abstract(J)2050年カーボンニュートラルを実現するには、経済効率が高くスケールアップが可能な脱炭素化手法が必要になる。これには、都市レベルで、屋根上太陽光発電とEVを蓄電池として限活用した「SolarEVシティー構想」が大きな可能性を秘める。将来、ますますコストの安くなる屋根上PVとEVをリンクし、安価でカーボンフリーの電気を市中で十分活用できるシステムを構築することで、都市の脱炭素化を加速させる。今後、EVの普及と共に、屋根上PVとリンクしたV2H(vehicle to home)、V2B(vehicle to building)システムの導入を進め、できるだけ多くのEVオーナーに十分なメリットを提供していけるかが課題である。

Abstract(E)Achieving carbon neutrality in 2050 will require decarbonization methods that are economically efficient and scalable. In this regard, there is great potential for the "Solar EV City Concept," which utilizes rooftop solar and EVs as storage at the city level. By linking rooftop PV and EV, which will become increasingly cheaper, buildings can utilize abundant cheap and carbon-free electricity helping accelerate decarbonization of the city. With the spread of EVs, we need to promote V2H (vehicle to home) and V2B (vehicle to building) systems linked to rooftop PV to build the SolarEV City. The issue is whether we can provide sufficient benefits to as many EV owners as possible through the system.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
