Multiple Manufacturers Push Hydrogen Fuel Cell Cars, But Can They Catch Tesla?

MojoKid writes After years of working on prototype vehicles, multiple car companies have announced a major push for hydrogen fuel cell automobiles. At the LA Auto Show last week, Toyota showed off its Mirai, a four-door passenger sedan with a $57,500 base sticker price and a hydrogen-only fuel system. Honda recently delayed its hydrogen-powered FCX Clarity Fuel Cell Electric Vehicle until 2016, while Hyundai is planning to build 1000 fuel-cell powered Tucson's by the end of the year. Currently, most proposed hydrogen fuel cell vehicles are actually combined hydrogen-electric designs. Hydrogen gas, under enormous pressure, is used to drive a generator, which then charges a lithium-ion battery. Toyota plans to sell up to 3,000 Mirai a year by 2017, which would put it well below Tesla's own sales projections for its Model S — but at a lower overall price point. The pressurized fuel tanks in the Mirai can hold a total of 122 liters of hydrogen for an estimated range of 300 miles. A standard gasoline-powered car with a 122L capacity at 30mpg would be capable of traveling 960 miles. Proponents of hydrogen point to the vastly improved fueling time (roughly equal that of gasoline) as opposed to the 20-60 minutes required to recharge a vehicle like Tesla's Model S.

      Well, first you'd need to find a place with a nitrogen-cooled tank made out of a special alloy open-cell metal foam encased in a high-pressure-rated carbon fiber hull. Hydrogen is incredibly difficult to store, and requires specialized equipment and constant active cooling, which means running pumps and high-power apparatuses to continuously refine and condense liquid nitrogen and dry ice coolant.

      Your car would store the hydrogen less efficiently: parking for a long time would drain your tank, so infrequent drivers will consume more fuel than frequent drivers. Electric cars do this, too, regardless of electronics; but even a NiMH battery can hold 70% of its charge after 1 year of disuse. Tesla drains too much power keeping standby electronics on standby. Gasoline sours, but you can add treatment to store it for years. Between electric and hydrogen, it's potentially a wash, unless hydrogen leaks much faster.

      Beyond that, the fill-up method is roughly the same as gasoline, aside from needing to use a sealed, pressurized connector. Misaligning the connector will vent hydrogen, if it's misaligned in such a way as to satisfy the safety mechanism yet not gain positive seal. Fortunately, the car will likely contain a one-way valve (a ball on a spring, or a ball not on a spring but with a grate behind it such that internal pressure forces it up to seal), so your tank won't vent: it'll only open the valve when the pressure outside is greater than the tank pressure.

This is not exactly a secret; there are several books about it. Hydrogen is a terrible fuel for vehicles, only slightly better than purest snake oil. The energy per unit volume is so low that you have to have ridiculously high pressures to accomplish anything (at 5,000 psi hydrogen only has an energy density of 0.25 pounds per gallon, one twenty fourth that of gasoline) and that means either super expensive exotic techniques or very heavy fuel tanks.

      Here, I'll chart my theoretical system:
      1. Oil comes into a burner and fires the hot side of the sterling engine. Besides exhaust, this would be insulated to help maximize heat. 500F (260C) would be a goal, hotter if I can get it. Utilize waste heat recovery so the exhaust is condensing, such as by heating the incoming air.
      2. The 'cold' side of the stirling engine would be hooked to my hydrolic system, which would have a maximum of 180F(82C), which gives a carnot* efficiency of 33%
      3. Hopefully everything could be cooler, of course. 120F/50C gets me to 40% max efficiency. 600F on the hot side gives me 45%, at which point the stirling might actually be at 30%

      With an external-combustion engine like a sterling engine, the heat is lost.

      Where? Into my house it's not lost. My house is water-heated, I toss a heat exchanger on the hot side and I'm using the 'waste heat', by dumping it into my 20C house. Sure, I'll lose some efficiency compared to dumping it outside, but the point is efficient combustion and capture as much of the waste heat as possible, not a stirling(or other engine) maximized for electrical generation efficiency.

      Also, fuel usage will go up by the amount of electricity I'm generating(and no longer buying from the electric company). Trick is, with a properly sized system I can claim 90% efficiency* in using my oil overall, even if the electrical generation portion is only 20% efficient. I just use the other 70% of the energy derived from burning the oil as low grade heat(house thermostat is normally set to 65F, about 18C).

      Because I'm 'effectively' using 90% of the energy in the extra oil I burn to create electricity under this scenario, so long as I'm not creating so much electricity that I'm producing more heat than what I need for heating needs. Obviously I wouldn't run this in summer unless there's a power outage. At which point it'd be hooked up to a heat exchanger OUTSIDE.

      Remember, my measure of 'efficiency' amounts to 'what percent of the energy in this gallon of oil did I actually use for my intended purposes'. Burning it and recovering heat is a known high efficiency process.

      Okay, example time:
      I use 100 units of oil a year right now. Because my boiler is 90% efficient, that means I need 90 units worth of heat.
      I put in an engine of some sort - it could be diesel(they can run on #2 heating oil), turbine, or stirling. The choice of which is engineering. Set up to have the heat scavenged for my house, it's 20% efficient.

      So now I burn 100 units, I get 20 units of electricity, 70 units of heat. Since the goal is not overproduction of either resource(IE more than I consume), and I was previously buying the electricity directly(it was still ending up as waste heat in my house). I'm now short 20 units of heat.
      So I increase my burn to 129 units of oil. I produce 25.8 units of electricity(cutting my electric bill even more), and 90.3 units of heat(rounding...).

      29 units of oil to produce 25.8 units of electricity = 89% efficient. Going by local electric prices and the cost of home heating oil, I can produce the electricity cheaper than the electric company, and that's without considering that the oil companies cut the price more the more you buy.

      Remember, my limitation is the heat demand of my house - while 90% efficient use of the fuel is cheaper than the power company, a 30% efficient generator isn't. Also, the power company will stop paying retail if I exceed my net usage, though I checked, a cogeneration system DOES count the same as solar panels and wind turbines, so net metering applies. It's part of 'winter power is more expensive than summer' that goes on here.

      It doesn't matter whether the electrical generator is 1% efficient or 50%, as long as I have the ability to scavenge most of the waste heat for a purpose I'd be burning the fuel for anyways. The only difference is the total amount of electricity I can generate - 1% wouldn't be much electricity displaced. 50% I might as well act as a generation source for the power company.

      *Efficiency in this case is a combination of burn efficiency(99%+) and looking at exhaust temperature vs inlet temperature - 70F when you're drawing in 0F air is still energy lost, and while you could put a heat exchanger there to warm up the incoming air using the exhaust air, I don't think it would be worth the cost to do it safely.

      Around this, you place a gyroscope constructed of a sphere of ultrapolished silicone, 2cm thick, plated on its interior with 7mm of niobium, and assembled from two fused hemispheres. The gyro itself is suspended in superfluid helium-4 at 1.95K, and rotates in a plane parallel to the surface of the Earth.

We also have a network in place for distributing electricity.

      If you run down the list of known chemical and electrical means to store energy, you find out the storage medium with the best energy density (both by weight and by volume) which is easiest and safest to store, transport, and use are... diesel, gasoline, and kerosene. There's a very good reason those have become the fuels which dominate transportation. They're hardly the cheapest (coal is an order of magnitude cheaper per Joule, which is why EVs are able to operate more cheaply than ICE vehicles).

      There's a bad tendency for people who dislike one aspect of a fuel (e.g. it pollutes) to downplay any advantages of that same fuel. Unfortunately that results in said people ignoring common sense qualities which affect the economic viability of alternative fuels. Such is the case with hydrogen. It doesn't pollute at the combustion stage, so supporters flock to it while ignoring everything else. It's damn hard to store (needs to be compressed to 1000+ atmospheres, and even that doesn't have competitive volumetric energy density with gasoline). It's difficult to distribute (H2 is a tiny molecule, and will leak from hoses and fittings which are otherwise airtight and watertight).

      And does it really not pollute? Well how do you make the hydrogen in the first place? If you use electrolysis to crack water, first you need to generate the electricity. That's usually from a coal plant operating at 45% efficiency at best. Then the electrolysis is about 65% efficient at best. Then you put the hydrogen through a fuel cell which can be 90% efficient in the lab, but peaks at about 70% efficient in commercial applications. Multiply these efficiencies and you get 20.5% efficient - worse than gasoline ICEs, which are currently about 25%-30% efficient. Since a smaller percentage of the energy in the fuel gets sent to wheels on the ground, it can potentially pollute more than gasoline. The story changes if we can convert most of electrical production to a clean source like nuclear, but the recent trend has been anti-nuclear and pro-renewables, which ironically results in the shortfall being taken up by more coal and gas.

      The most promising conversion method is actually to process natural gas to strip the hydrogen. But why do you want to do that when natural gas in itself is nearly as good a fuel? Is it so you can brag there's no carbon coming out the tailpipe? When all you've done is secreted away the carbon emissions in the early processing stages?

      My money is on electric vehicles.

      The same is true for EVs - the EPA MPGe figures assume 100% efficiency for the production of electricity and charging. Factor in 45% production efficiency and 70% charging efficiency (what an engineer recorded after years of charging his Prius converted to a plug-in hybrid) and they're only slightly more energy efficient than ICEs. I'm not against EVs per se - one of the places I used to work at used electric golf carts to move equipment around so I completely agree there are applications where they are superior. And as you point out there are several potential breakthrough technologies (tied to battery energy density and charging speeds/efficiency) which could make them completely viable. But don't ignore other advantages of hydrocarbon fuels simply because you don't like the idea of spewing carbon into the atmosphere.

With the increased share of non-programmable renewables like wind and solar, hydrogen stations can produce their hydrogen when there is an excess of available power.

      It's not just the price of batteries, which may very well come down: it's their weight.

Sure, hydrogen cannot compete in the short range with batteries, but it is much better in the long range. And yes, batteries are much heavier than the tanks containing hydrogen.

      The energy density of Li-ion batteries is about 100 Wh/kg, hydrogen is 32500 Wh/kg. Even accounting for 50% conversion efficiency and a hydrogen tank 10 times as heavy as the hydrogen, you still get over 1600 Wh/kg, well over 15 times Li-ion! Then of course you need to add the fuel cell system, which is dimensioned by power (not by energy as the tank is), and its weight is why FC cars are better in the long range, where this weight is a smaller fraction of the total FC system weight.

      Running fuel cells on hydrocarbons directly is not an option (slow chemistry), but they can be reformed on-the-fly to hydrogen; in fact you can do that with diesel. The only problem is, the system gets so much complicated it is soon not worth the bother when you have a highly dynamic load as is the case for a car.

If there's one every hundred miles or so along every long-distance travel corridor (which in the US is mostly just the interstates, though there are a few areas with long-distance highways) then coverage will be complete.

      With electric vehicles, 95+% of charging is done at places where vehicles spend lots of time parked, primarily homes and workplaces. Such charging doesn't need to be particularly fast. Fast charging only matters when you're driving distances beyond the range of your battery.

      You mention North Dakota, for example. Move the slider on that map to 2015 and you'll see they plan to put three superchargers there. That will cover the long-distance travel across ND, and most long-distance travel within ND. Add another supercharger on highway 2, midway between Grand Forks and Minot and you'll have covered nearly all of the rest. Add four of five more and you'll be able to get to any destination in the state without worry.

      Purely battery electrical vehicles give customers control of charging their cars. You only need a charging station if you are on a long range journey.

      Agreed. Because you can charge your battery electric car in your garage using a regular power point, albeit slowly, you don't actually need a single dedicated fast-charging station in your whole city in to use a BEV. That lets early adopters buy BEVs without waiting for infrastructure to develop. OTOH, hydrogen vehicles aren't possible without the supply infrastructure, so even if they are suitable for more early adopters than BEVs, the early adopters themselves are prevented from owning them.

      It's the same with commerical fuelling/charging stations: Hydrogen filling stations must be dedicated facilities like conventional fuel stations, with EIS and council planning (and protesting neighbours), and require special dedicated equipment. And then the station itself needs a yet larger scale hydrogen production/supply infrastructure to fill its own tanks before the station itself is practical, meaning that the filling stations themselves may be impossible in many regions that lack the industrial supply infrastructure.

      But mains electricity is everywhere.

      Any location with a commercial power supply can install a fast-charge station, and any location with any electricity can install trickle-charge plugs. It doesn't require special facilities (gas storage tanks, safety clearances). In most areas it probably doesn't even require special building approval. So a shopping mall can install charging stations in their car park since they already run power lines out to the car-park light-poles. Any commercial car park building can install charging stations. Your office or apartment building can install them in their private car park. Etc. It makes it much more likely that the infrastructure will develop rapidly and organically as the number of electrics on the road increases.

      So even if there are more early adopters willing to drive medium-range hydrogen vehicles than short-range battery electrics, hydrogen is so restrictive that the overwhelming majority of those potential hydrogen early adopters are excluded. OTOH, almost all potential BEV buyers already have standard power-points they can immediately plug into; and every potential fleet buyer can install faster-charging stations at their depot/garage without special facilities or planning permission. That solves the chicken and egg problem.

Any car that's going for half of my year salary is getting passed up. Adoption is going to be abysmal. At the price this thing is at, I may as well buy a Tesla, which is way more compelling. My last car was from 2006, it's paid off, and you're going to have a hard time convincing me to give that up. I've got rent to make and a lot of other expenses... the new car is the last thing on my list, and at that price, it ain't happening.

  61. Economics of auto parts by sjbe · · Score: 1

    Can you explain to us how the accounting is done?

    Yes though you are asking a bigger question than you may realize.

    If I buy a part 20 years on for a vehicle for which I'm not even the first owner, and it's a part which can fit 20 different vehicles, how do you account for the profit?

    Whose profit are you trying to account for? The manufacturer of the part? The OEM who built the car? The dealer? For OEM parts the OEM (think Ford or GM) will purchase the parts from a supply chain during the production run and they will usually contract for several years worth of replacement parts in addition to the production run - usually something like 3-7 years worth. Once the original production run ends it usually moves into aftermarket manufacturers, sometimes custom replacements or sometimes the original manufacturer will continue to produce the part for some time if there is a market for it. It's not unheard of for the OEM to keep the supply chain for replacement parts running for 15-20 years though that isn't the norm.

    You don't have accurate statistics on failures on vehicles that old, because people don't bring them back to the dealer for service.

    Actually dealers do see a lot of older vehicles for service so they have pretty decent information. Aftermarket parts dealers also have a pretty good idea what parts fail commonly on which vehicles. Furthermore the parts that are failing in year 5 are mostly going to be the same as the parts failing in year 20 with a few additions.

    From my various forays into automotive parts replacement and part ordering, I know that without exception the manufacturers charge absolutely abusive prices for replacement parts.

    Actually it isn't usually the manufacturer charging the outrageous markup, it is the dealer who is independent. (And you are right, it is outrageous) The OEM usually charges the dealer a 10-40% markup. Anything you buy from a dealer typically has a minimum of an 8X or more markup over the actual manufacturing cost. To give you an example, my company makes a jumper harness for a GM vehicle. Costs us about $3.00 to make it and we sell it for roughly $4.00. We are a Tier 3 so by the time it gets to GM it probably costs somewhere around $6-8 once you factor in the markups along the way and they probably double the price they sell to a dealer. If you were to march into a dealer and try to buy our part by itself from a dealer it would cost you somewhere between $30-50 if they would even sell it to you as a standalone product which they probably would not. I've seen assemblies that cost $3 to actually make selling for $200+ and the majority of that markup comes from the dealer.

    You're telling me that having more expensive parts doesn't lead to more profit?

    No, I said a larger part count for the OEM generally leads to less profit. Increasing part counts has no benefit to the OEM. Ford has competition and they cannot simply pass on any markups to the car buyer. In essence they have a cap on how much the can sell the car for. If they make a more complicated part that will cost more to make, it will break more often and sooner and Ford will make less profit. There is a limit to what they can charge for aftermarket parts too though the price elasticity is less sensitive. If a car constantly breaks people tend to get rid of the car in the long run. Furthermore the reputation benefits foregone in lost sales alone far outweigh any minor additional profit from more expensive replacement parts.

    Automakers derive significant profit from parts sales, and EVs both have less parts and are less prone to failure than vehicles with ICEs.

    They do get some profit from part sales but only after the warranty runs out and not nearly as much as you probably think. The expense of recalls from failures can easily swamp any profit from a vehicle line. Eve

      I defy you to find an engineering consensus that there is a "best way to do it" and certainly nothing as simple as just swapping out the torque converter. That might be your opinion but it isn't a widely shared one.

      That's because there's a lot of assholes out there. It wasn't my idea, I simply recognized it as the best solution. So have some automakers. It's not an accident that Honda got it right, or Subaru for that matter. Once you get caught doing something stupid, you have to pretend like it was smart or you look like an asshole to idiots. Since most auto customers are that, you don't have to do it right to sell cars. Ford proved that forever. They did see their lead slipping, though, so they decided what the fuck, I'll do it correctly and see how that works out. And guess what? They're selling lots of those cars.

      The only other design which makes sense is true parallel hybrid, with different wheels driven by different power systems. And sure, you can use a manual box, but that's actually trickier to do well (don't have the luxury of having the transmission tell you what it's about to do.) But if you're not driving separate wheels, then it pretty much has to go there. There's literally nowhere else that makes sense, because literally everywhere else adds complexity. Putting it between the engine and the transmission is the option which adds the least parts, even down to bracketry.

  62. Hydrogen cars = doomed. by aurizon · · Score: 1

    There is no chance of a hydrogen economy. The production of hydrogen by electrolysis is then followed by a compression stage to 5000 psi (now there is a bomb for you!!!). This energy of compression is mostly lost, about 30% could be recovered by letting the hydrogen for the fuel cells de-compress (expand) via a small turbine. This electricity can be stored in a battery to assist the fuel cell electricity storage. The production of hydrogen by electrolysis or from coal/coke is very inefficiecnt
    Hydrogen has the widest known explosive range of any gaseous fuel, so any leaks will constitute a great risk of explosion - far worse than the Tesla. A car full of compressed hydrogen, refilled and used again and again, is sure to leak. Sure they will put some sticky tracer in the hydrogen so you can smell it, but it can still detonate with the tiniest spark.
    Lithium or other future batteries will block any chance hydrogen has of success. They might get fully swappable lithium batteries in quick swap battery cases, so a battery change takes a minute or so - much like a fill up of gas.
    Capacitors will never work, the energy density is too low, Capacitors are the functional equivalent of a spring - fast, but not large enough.
