所以用鋰電池作為汽車能源只是過渡性質, 非長遠之法. - #128 [mrbeansr], 17-10-20 18:05不過至少兩個方法都比直接在車上燃燒化石能源好很多!

電動車能源來自發電廠, 如果發電廠產生能源方式不夠環保, 電動車表面上環保, 但實際上是將問題交到發電廠身上.
fuel cell 使用 Hydrogen, 如果生產 Hydrogen 的方式不夠環保, 也是有環保問題在背後的.
不過至少兩個方法都比直接在車上燃燒化石能源好很多! - #126 [mrbeansr], 17-10-20 17:15HKYAN 排山倒海式貼圖文, 圖片又 oversize, 除了自己友, 有幾多人有心機睇?
不過可以洗版同自己友冚野
回返正題
中國電動車會爆但英國人又買難道他們是儍的嗎?
公有公理, 婆有婆理
從某些港人政治觀點看來, 英國人是儍的
但買 BYD 的英國人和美國人, 包括畢非達 (入股 10% BYD), 就是一個商業決定.
HKYAN [#94] 都講:
In the EV technology, BYD just an option, this option mostly is the cost,
but not its technology!
HKYAN 最新觀點 [#123]
“電池大巴並唔環保,佢使用既電池數量係電動私家車既多倍,電池生產過程,非常污染環境...”
國際性環保組織做了一個 40 國家研究, 有晒 data, 包括電力生產污染.

The ‘electric cars aren’t green’ myth debunked’
It’s time to bust this thing wide open.
‘Electric cars have higher manufacturing emissions than normal cars. Electric cars also use electricity that has its own footprint. And put together these two factors are a ‘dirty little secret‘ that negate any climate benefit of electric cars!
No. Let’s clear this thing up once and for all.
It’s all about the juice
One of the most irritating things about articles discussing electric car emissions is the way it’s always very black and white. In one corner you have the ‘zero emissions’ brigade and in the other the ‘worse than combustion engine’ crew.
But as ever, real life comes in shades of grey.
The reality is that even after you account for the bigger manufacturing footprint of an electric car it is all about the fuel mix of the power you use, the ‘juice’ if you will.
Using coal powered electricity electric cars do nothing to cut emissions, using natural gas electricity they’re like a top hybrid and using low carbon power they result in less than half the total emissions of the best combustion vehicle, manufacturing included.
In our recent study ‘Shades of Green: Electric Cars’ Carbon Emissions Around the Globe‘ we calculated grid powered electric car emissions in twenty countries. But we actually had data for quite a few more countries we didn’t include.
So let’s break out the data and put this thing to rest.
Mapping electric car emissions
The following map compares the carbon footprint of electric driving using average grid electricity in 40 or so countries. The actual carbon intensity of electricity you use may differ from the national average for a number of reasons, but it’s a great starting point.
The results are shown in terms of grams of equivalent carbon dioxide per vehicle kilometer (g CO2e/km). Each estimate includes emissions from vehicle manufacturing, power station combustion, upstream fuel production and grid losses.
Of the 40 countries covered in this map emissions vary from 70g CO2e/km in hydro loving Paraguay, up to a 370g CO2e/km in heavy coal using India. The US average is 202g CO2e/km, in China it’s 258g and in Canada 115g.
Compared to combustion vehicles
In coal heavy India, China, Australia and South Africa electric cars using grid power are just like typical gasoline vehicles, in the 25-30 MPGUS range. In the UK, Germany, Japan and Italy they are as good as the best petrol hybrids, in the 45-50 MPGUS range. But in low carbon supply places like France, Brazil, Switzerland and Norway they are in a different league, averaging well beyond 100 MPGUS for equivalent emissions.
Electric cars are as green as their juice
Critics of electric cars love to talk about manufacturing emissions and putting horses before carts. But they never seem to offer any better solutions...
Electric cars are far from perfect, and there are plenty of valid ways to critique them. But let’s not pretend that a gasoline vehicle can compete with an electric car in terms of carbon emissions. It’s just not a contest.
Give an electric car the right juice and it crushes combustion engines.

- #123 [HKYAN], 17-10-19 14:33電池大巴並唔環保,佢使用既電池數量係電動私家車既多倍,電池生產過程,非常污染環境,而現在大陸既電池廠大部分集中在安徽河南河北一帶,果度一百年都唔會空氣好,而且電池用完後,棄置亦係一個大問題!所以,從生產電池材料開始,到生產電池,發電,充電,棄置,其污染指數到最後可能大於現有能源,根本唔可能作為大批量集體運輸用途。但現在大陸電池廠正在拼命上馬,所以,大陸一定要搞一帶一路輸出過剩項目以續命!
但電動車不是壞東西,就等於你有電燈,也可以有手電筒,沒有衝突,但拼命發展電筒來照明就過火了!
而且,大陸政府對電動車補貼係公開秘密,所以,梁震英重岸99去補貼香港巴士公司去買大陸電池巴士,人地都掩住嘴偷笑,因為佢地目標係拿政府補貼,巴士送俾你都得! - #122 [HKYAN], 17-10-19 14:11所以,英國美國日本都全部集中燃料電池巴士,只有香港政府重晒時間去玩大陸既電池大巴,唔使前都晒時間

中國是全球最大車市,當地為了防治空污,力推電動車。儘管中國車廠爭相投入研發,分析師說,特斯拉(Tesla)電動車的品質遠勝中國車,樂觀預估特斯拉將在中國攻城掠地。
CNBC、霸榮(Barron’s)報導,Piper Jaffray 的 Alexander Potter 17 日報告稱,他本週在北京拜會電動車貿易團體後,認為從當前情況看來,特斯拉無須擔憂中國車廠的競爭壓力。品牌和車輛表現有其重要性,這方面無人能與特斯拉抗衡,更別提中國車廠。
中國將實施電動車配額制,2019 年起大型車廠的電動車銷售必須達到生產總額的 10%,2020 年升至 12%。
Potter 指出,搭過中國電動車的人都會說,這些汽車並非出色的消費產品,此種情況下,電動車需求成長難以永續。特斯拉是唯一無須政策補助,仍有競爭力的電動車。就算沒有相關政策,特斯拉也不會陷入絕境,其他車廠則不是這麼一回事。未來幾年更有實力的車廠也會推出電動車,屆時才會知道這些車廠的電動車能否激發消費需求。
Autocar 報導,中國汽車工業協會(CAAM)預估,今年中國電動車銷售將達 70 萬輛,打破新高。今年 9 月中國電動車銷售年增 80% 達 7.7 萬輛,今年前 3 季電動車總銷售量達 39.8 萬輛。由於第四季是中國汽車銷售旺季,車協估計今年銷售量上看 70 萬輛,高於去年的 50 萬輛。 - #112 [HKYAN], 17-10-19 10:44Where is BYD? don't be silly!

Fuel cells in vehicles generate electricity to power the motor, generally using oxygen from the air and compressed hydrogen.
…hydrogen vehicles centralize pollutants at the site of the hydrogen production, where hydrogen is typically derived from reformed natural gas. Transporting and storing hydrogen may also create pollutants
