氫能最大的問題就兩個,生產跟儲存,剩下都非常棒
大概就跟台籃的雲豹或鋼鐵人一樣,問題只在進攻跟防守而已
日本對於氫能有極大的信心源自於國內的基礎建設
他們有非常完善且密集的地下天然氣管道來供暖,同時他們也是LNG超級進口大國
兩者結合來,天然氣供暖後尾氣來提煉氫氣是再適合不過了
用這樣的背景來看,日本確實有本錢發展氫能,無論是氫內燃機或FC
因為尾氣成本本來就低,就整個國家能源戰略的副產品當然好用
但反過來說,全球又有幾個日本這種基礎建設?
不管FC/氫內燃機,你氫氣要怎麼運輸儲存? 還不就高壓罐或高壓桶槽?
當然你也可以建地下管啦,只是你要確定那個成本和影響耶
先不提製氫來源,所以你氫氣做出來,還要額外花能源壓縮
不壓縮一來載運量少,二來你把氣體灌到桶槽的時候要額外的設備打進去
然後再用槽車或拖車(燃料未知)運到各地加氫站去,這效率請問一下好在哪裡?
此外加油站人員大概都要有特高壓或高壓氣體操作執照以及經驗,不然會出人命
生產面的部份,日本可以用供暖的天然氣尾氣來生產
石油大國、煉油大國大廠也有副產品或尾氣來生產成本極低的氫氣
那上述都沒有的國家大概最好用的就是大家最愛的電解水
電解水眾所周知的效率差,除非你電多到用不完
但電那麼多,大概就是綠能因為不穩定性所以超過需求的裝置容量在設置
那至於設置那麼大的裝置容量綠能效率如何?
可以去問問歐洲為什麼要買那麼多LNG...
有人也會提出加州那個分散式"自給性"加氫站,但也不太適合多數地區
1. 加州氣候是世界聞名的好,前陣子暴雪下到亂七八糟加州不過也就下些雨
(當然加州人在那邊抱怨陽光稅繳了不值得就另外一回事)
2. 需求高的時候那個加氫站比充電站還搞笑,充電站至少你等前一台車充完就有
加氫站前一台車充完你要等製氫機生產,當陽光不足的時候他本身還是吃電啦
FCV有搞頭的大概還是商用車,我從數年前就開始談過
一般自小客乘用車87%發展受限
你有固定路線、固定駕駛時間、固定地點填充燃料
尤其是煉油廠的運輸油罐化學槽車等等,用FC應該是有些搞頭
但豐田終究是面向大眾一般乘用車市場
氫氣運用日本本土OK,推廣各地市場想太多惹
留個神主牌每年丟點香油錢進去就好
※ 引述《QuentinHu (囧興)》之銘言:
: 豐田章男辭社長,接受Financial Times 的訪問有提到以下
: https://www.ft.com/content/11e4e53e-d4b0-4de3-b4eb-28c97b52b0a1
: “Because of my strong passion for cars, I am an old-fashioned person in regar
: ds to digitalisation, electric vehicles, and connected cars. I cannot go beyon
: d being a car guy, and that is my limitation,”
: 某種程度上等於是承認要為目前電氣化失敗負起一定程度責任,也是說明Toyota集團的高
: 層,有了解自己失敗在哪
: 可以猜測一些計畫會被取消,例如氫動力,當初看到Yaris 氫動力跑車,就覺得根本搞錯
: 方向,整個跑車計畫的公關,等於只在講氫動力很強,是現在燃油車的替代燃料,用跑車
: 來展示技術是在講燃料的容積密度問題,這是非常工程的角度,坦白說No body cares ,
: 也完全忽略現今電動車發展大勢,早就不是單純換掉動力單元,還加上了智慧控制跟駕駛
: 而且當動力演進趨同化,你有同步電機我也有,新創廠也能買到刀片電池跟麒麟電池,那
: Toyota除了可以用CTC整合跟上,跟規模夠大有辦法降低成本以外,更重要的是這些成本
: 差,Toyota應該是要在車子產品本身塞入更多消費者會愛好的功能,但這幾年根本沒看到
: 他們在相關的軟體跟connectivity聯網上有開發出什麼相關功能跟應用
: 未來電氣化加速,個人推測,純燃油跑車例如GR Yaris / Corolla /Supra 都很有可能是
: 最後一代純燃油款
