This sounds like a big deal if it works out. However, there are many false steps along the way (and many steps to be taken) [ towards cellulostic ethanol].
SO there is already quite a market for H2. Question is - should they generate it by steam reforming of methane (as they do now) or from excess solar and / or wind energy? Depends on the price of carbon (if you had one?), or mandates.
Well that's something no-one predicted. If "they" could even move the mining machines to where the heat could be used (like in houses in cold places), it would be something, but most of the heat is just exhausted to the air wherever electricity is cheap.
Could improve the stop/start city performance of most hybrids, IMO, and thus valuable.
Humans can drive without HD maps, and in most cases, without maps at all. Humans have driving and traffic rules and object recognition. We can drive without Lidar and Radar, just high resolution colour stereo imaging and almost perfect object and scene recognition (it not perfect, then fit for purpose anyhow). We do not need to know where everything on the route is in advance, just the few turns we may need to make. It looks like a solution looking for a problem to me.
A very good idea. H2 is a lousy way to store and move energy, Ch4 is much better. IMO, it doesn't matter where the carbon comes from. If you have CO2 from ethanol, well and good, else, use any source, like wood, even coal.
The US army could do quite well if they piggy back on Uber - Uber will move 10x faster than they will, and while the results may be a bit rough, at least they'll get through some designs fast.
I'd still add a 100 - 200 Kw Generator, maybe based on CNG (or just diesel), to extend the range and give you some extra "get you home" range. Also, if you used the genset for say 1/2 the time, you would have less recharging to do and could turn the bus around quicker.
Fine, but how much does it add to the cost of a bus and who can maintain the increasingly complicated systems...
Good, but a bit "battery intensive". I wonder can you plug banks of PV into them for extra greenery.
The diesel fightback continues: first Bosch, now this. We can expect BMW as well - Audi seem to have new egg on their face, but they'll get over it. The problem is what to do with all the existing diesel vehicles in cities; can they be cleaned up, or do they need to be replaced (or converted to natural gas). If they have to be replaced, can we get a rational sequence for retiring them, or do we just do it by model year. The main thing is to get the worst polluters off the roads soonest.
Obviously - if you can diesel, you can expect CO2 to go up in the short term UNLESS you can afford Norway level subsidies for hybrids and EVs. + Norway gave free use of bus lanes and tolls and parking - who could resist such a bribe set.
Or, you could put diesel engines in the buses for occasional use, make them like range extender or PHEVs. If you have this, you can manage the charging depth much better and keep the batteries in use much longer. @harvey, I had considered the idea of paying drivers to conserve fuel. My view was that it is easy to start, but hard to end.. Say you introduce it in year 1, and based the payback on the previous year's mpg - OK, the mpg will increase, and the guys get some cash. What happens for year 2 - do you reset the base level to the year 1 levels (which will make the drivers unhappy), or leave it at year zero levels, which makes the bus company unhappy. What if they get more efficient buses, do you have to reset the base levels ... It looks like an HR minefield. Or, you could rank the drivers against each other, but that would favor drivers on the smoothest routes. Or, you could rank the drivers by personal improvements over the last year or two, and they are ranked for a payout for the top 5(say) as long as there was a > 1% improvement. But that would make it difficult to get them to switch routes. Never simple, is it ...
Looks like it is for petrol engines as the torque level is quite low. It will be interesting to see how much extra it costs and how much it increases fuel efficiency. I wonder will they start to make higher voltage mild hybrids. My understanding is that the 48V limit is for safety reasons - could they bring it up to 72 or 96V and still keep it legal (or in what trade blocks could they do that).
It doesn't look like it could carry containers, so what use it it? is there that much large non-containerized traffic on the roads ?
Here is a better report on it. http://www.autoexpress.co.uk/car-news/103331/new-bosch-tech-drastically-cuts-diesel-nox-emissions They say it will take 2 years to get into cars. However, it looks like various companies are fixing it bit by bit anyhow, but this demonstrates how far they could go.
Diesel refuses to die. I wonder does this use the new Bosch technology or is this yet to come. Once again, when the gun is to the head, it is surprising what VW can do, given a year or two.
I wonder does this use the new Bosch technology ? It is funny how, once the gun is put to the head, the diesel people seem to be making good progress with NOx. Still, it is nice to give electrics a run for their money. And no reason not to (mild)hybridies this (except for the cost).
Good news for European car manufacturers if this is real. It is unusual to hear statements like, they have "solved the NOX problem." Questions: How much extra will this cost? When will it be available on new cars? Will it be retrofittable ? Can they fit the necessary hardware soon, even if the software takes longer? How reliable will it be?
The BUsBaar system of Opbrid looks better. It can charge at 1 MW compared to 200K for this one. + there are no wireless losses.
I imagine you'll find that charging at chargers like these won't be cheap, it will be "competitive" with gasoline on a per mile basis. Also, it may not be very good to charge at such high C rates. I dread to imagine what it will cost to charge in Europe where gasoline is $6 - $8 / us gallon. So, you'll be able to charge cheaply at home and in work, but once you deviate from your known routes and need fast charging, you'll be paying full price.
Looks very good. The auto rickshaws have very high pollution for their size. Replacing the drive-chain with an electric one would solve the local pollution problem, but they would not need very much energy as they are very low power vehicles. So they won't stress the grid out so much.
This sounds like a good thing - especially if it scales up to match the Haber process.
