Thread: Avto akumulator je mrtev: naj živi gorivne celice

Industrija in akademska imajo vse, ampak obupal na baterijski pogon avtomobilov in pripravljajo pot za vodik postati gorivo prihodnosti. Moj kolega James Ruppert bo vesel, da slišim, da včeraj, v kleti Institute of Civil Engineers, sem imel avtomobilski razodetje. Sem bil na sestanku kaj se imenuje UKH2Mobility, krovno ime za vlado sponzorirane srečanje gospodarstva in znanosti, vsi, ki delajo za vodik resno goriva prihodnosti.
Michael Fallon, vlada Business in Enterprise vlade, pomirja hrup približno 400m iz javnega denarja, ki se uporablja za, er, olje kolesa prihodnosti vodikovega goriva omrežja. Denar bo tudi zagotoviti, da Združeno kraljestvo pripravlja ustrezne tehnologije za postopen prehod na vozila, ki se napaja z gorivnimi celicami.
da, vem. Weve slišal je vse pred. Pogumni novi svet nizko-Co2 in vse to. Vendar pa je bilo samo odvržejo pripombo, ki ga Toyotas Akihito Tanke, da električni avtomobili ni bila prejete javnosti, kot tudi bil upal.
Potem se je, da sem spoznal, avtomobilska industrija je precej obupal z baterijskim napajanjem - čeprav ne električni pogon - avtomobilov. Počasi EV prodaje v ZDA - ki je pričakuje, da bo velik trg zgodnjega Usvojitelj - zapustili šefi z drago občutek potopu. Tik pod 15.000 EVs so premaknilo v 2012, izginjajo majhen odstotek 14m novih avtomobilov, ki so prispeli na cestah, ZDA.
Ive zdaj govoril dovolj ljudi v industriji, da zavedaš, da je EV nikoli ne bo postala resno sila na trgu. In Ive osebno doživeli razlogov, zakaj ko sem tekel Nissan Leaf dolgoročno preskusom avtomobil.
Prvič, ne morete spremeniti vaš um. Sem bil hurtling proti Gatwick, pozno za let. Pričakuje, da ga pogrešam, sem mislil, da bi našli let iz drugega letališča. Vendar Leaf strjena lava zaslužiti mi Luton ali Stansted. Drugič, strašno razpon v hladnem vremenu je resen problem. Na zasneženih vikend je padla šele 41 milj na napolnjenosti. Dobim občutek, da je to vprašanje ubijanje EV kjerkoli zunaj Orange County.
Na prvi pogled bi lahko rekli isto za vodik revolucijo dolgo obljubil. Ampak sem slišal nekaj zelo zanimiv idej na konferenci. Trdil da gorivnih celic je dvakrat tako učinkovita kot konvencionalne motorja in polnjenja za 300 milj območju morala tri minute. Mrežo dovajanja postaj bo valjani ven na countrys obremenjenih progah.
Je tudi poudaril mi da polnjenje električnih avtomobilov še tri ali štiri obleče velike obremenitve lokalnega energetskega omrežja, ki bo morda potrebna nadgradnja drago. Vodik, nasprotno pa bo svoje, dogovorili, dovajanje goriva omrežja.
Lahko deluje? Tudi, Ive imel srečo voziti več gorivne celice vozila (vključno z Merc B-razreda in Honda FCX, ki sem odpeljal v Londons City Hall) in so nujni predlog. Kot vsa vozila, električni pogon, so hitro, gladko, torquey in zelo rafinirano. Pogledal samo iz vožnje vidika, električni pogon avtomobilov so cilj absolutno splača prizadevati.
Weve dobil dobro desetletje, ostalo od motorja z notranjim izgorevanjem vladajoči vrhovni. Kot enega delegata UKH2Mobility ga mi, do leta 2025 bo bil vsak zadnji kapljico energetske učinkovitosti Vila iz konvencionalne notranjim izgorevanjem in svet bo res pripravljen za skok v prihodnost. Vendar to ne vključuje baterijski pogon avtomobilov.

Industry and academe have all but given up on battery-powered cars and are preparing the way for Hydrogen to become the fuel of the future. My colleague James Ruppert will be pleased to hear that yesterday, in the basement of the Institute of Civil Engineers, I had an automotive revelation. I was at a meeting of whats called UKH2Mobility, an umbrella name for a government-sponsored gathering of industry and academia, all of whom are working to make Hydrogen a serious fuel of the future.
Michael Fallon, the government Business and Enterprise minister, made soothing noises about 400m in public money being used to, er, oil the wheels of the future Hydrogen fuel network. The money will also be used to make sure that the UK is developing the technologies needed for a gradual switch to cars powered by fuel cells.
Yeah, I know. Weve heard it all before. Brave new low-Co2 world and all that. However, it was just a throw-away remark by Toyotas Akihito Tanke that electric cars had not been received by the public as well as had been hoped.
It was then that I realised the car industry has pretty much given up with battery-powered - though not electrically-driven - cars. Slow EV sales in the US - which was expected to be a big early-adopter market - have left bosses with an expensive sinking feeling. Just under 15,000 EVs were shifted in 2012, a vanishing small percent of the 14m new cars that arrived on the US roads.
Ive now spoken to enough people in the industry to realise that the EV is never going to become a serious force in the market. And Ive personally experienced the reasons why when I ran a Nissan Leaf long-term test car.
First, you cant change your mind. I was hurtling towards Gatwick, late for a flight. Expecting to miss it, I thought I would find a flight from another airport. But the Leaf couldnt get me to Luton or Stansted. Secondly, the terrible range in cold weather was a serious problem. On a snowy weekend it dropped to just 41 miles on a full charge. I get the sense that this issue is killing the EV anywhere outside Orange County.
At first glance, you might say the same for the long-promised Hydrogen revolution. But I heard some very intriguing ideas at the conference. Its claimed that a fuel cell is twice as energy-efficient as a conventional engine and refuelling for a 300-mile range should take three minutes. A network of fuelling stations will be rolled out along the countrys busiest routes.
It was also pointed out to me that charging even three or four electric cars puts a huge load on the local power network, which might require expensive upgrading. Hydrogen, by contrast, will be its own, bespoke, fuelling network.
Can it work? Well, Ive had the fortune to drive a number of fuel cells vehicles (including the Merc B-Class and the Honda FCX, which I drove to Londons City Hall) and they are a compelling proposition. Like all electrically-driven vehicles, they are quick, smooth, torquey and very refined. Looked at just from a driving point of view, electrically-driven cars are a goal absolutely worth pursuing.
Weve got a good decade left of the internal combustion engine reigning supreme. As one UKH2Mobility delegate put it to me, by 2025 every last drop of energy efficiency will have been wrung from conventional internal combustion engines and the world really will be ready for a leap into the future. But it wont involve battery-powered cars.
