給不想看完的人簡單的概論一下
電力—》電解水產生氫氣—》儲存氫氣—》氫能發電—》使用
電力—》存到電池—》使用
那一開始的電直接直接拿來電動車用不就好了......
拿去電解水產生氫氣不是多繞一圈嗎？
特斯拉現在在做的不就是這個嗎？
照原本蔡英文的說法
氫能—》電力—》非核家園
但氫氣你還是要電力去電解產生，哪來的電力去電解啊！
這種理智文一定會被噓的，因為不可質疑覺醒飯盒青年！
※ 引述《iebpk (夢十夜)》之銘言：
: 氫能到底好不好，來聽聽鋼鐵人馬斯克怎麼說啦
: https://youtu.be/YNV8qi_rJBg
: 結論：很笨 extremely silly
: It's just very difficult to make hydrogen,
: store it and use it on a car. Hydrogen is
: an energy storage mechanism. It's not a
: source of energy. So, you have to get the
: hydrogen from somewhere.
: 實在很難做出氫,儲存它,再用在車上. 氫是個儲存
: 能源的方式,不是一種能源. 所以你必須從其他地方
: 取得氫.
: If you get the hydrogen from water, so you're
: splitting H20. The electrolysis is extremely
: inefficient as an energy process. If you took
: a solar panel and use the energy from the solar
: panel to just charge a battery pack directly,
: compared to trying to split water, take the
: hydrogen, dump the oxygen, compress the
: hydrogen to an extremely high pressure or
: liquify it, and then put it in a car and run
: the fuel cell, it is about half the efficiency.
: It's terrible. What would you do that?
: It makes no sense.
: 如果你把水拿來分解H20. 電解水是效率非常低的過程.
: 如果你把太陽能板給充電池拿來比, 跟把水分解,拿氫,
: 丟掉氧,要極高壓壓縮氫或是讓它液態化,再把它放到車
: 上跑. 這效率差了一半. 太慘了. 為什麼要那樣做?
: 完全不合理.
: And then hydrogen has very low density. It's
: a pernicious molecule that likes to get all
: over the place. You get metal and .... from
: hydrogen. If you get hydrogen leak, it's an
: invisible gas. You can't even tell that it's
: leaking. And it's extremely flammable. When
: it does, it has an invisible flame.
: 而且氫的密度很低. 是很危險的分子會到處竄....如果
: 氫漏出來,是隱形的,你也看不出來在漏. 又易燃,燃燒
: 的火也是隱形的.
: If you're gonna pick an energy storage mechanism.
: Hydrogen is an incredibly dumb one to pick. You
: should just pick methane. That's much much easier.
: Or propane.
: 如果你要選儲存能量的方法,氫是非常愚蠢的選擇.不如選
: 甲烷,簡單多了. 或是丙烷.
: The best case hydrogen fuel cell doesn't win
: against the current case of batteries, so then
: obviously it doesn't make sense. That will
: become apparent in the next few years. There is
: no reason for us to have this debate. I've said
: my piece on this. It will be super obvious as
: time goes by. I don't know what more to say.
: 最理想的氫能燃料電池贏不過現有的電池,所以這很明顯不
: 合理. 再過幾年會更明白, 我們不需要在這裡辯論. 我要
: 說的就是這樣. 過些時間事情會變得清楚. 我不曉得還有
: 什麼能說的了.
