Interesting, to me in particular, because I know there has been some significant advocacy to have the nuke plants produce the hydrogen.

I bet the dates will be pushed back or not happen.

I am seeing several natural gas powered or suplimented trucks around my area.

Fuel cells are good for baseload. Delivery trucks, which do not go long distance, and are often used in more crowded areas where pollution is a consideration, would be well suited to fuel cells.

They have to be hybridized and already require power elecronics and VFDs.
The hybridization allows for energy recovery which is well suited to a start-stop scenario like delivery, garbage collection, etc.
Larger individual users would allow for larger plants or more cost-effective infrastructure
High-temperature electrolysis is not super efficient, but it is much better than low temperature variants, and could be a good way to baseload power stations and renewables.

There's some logic to this application, with lots of remaining technical challenges...

"Medium- and heavy-duty trucks contributed 23 percent of the overall greenhouse gas emissions in 2015, according to the EPA. In total, transportation contributed 27 percent of overall greenhouse gas emissions in 2015."

So total transport emmissions, excluding Medium- and heavy-duty trucks, were 4% of total? Phooey

Should probably read "Medium- and heavy-duty trucks contributed 23 percent of transportation greenhouse gas emissions in 2015"

We're not going to be burning fossil fuels at 40% (or 60% for CCGT) to make hydrogen.

I'm not a "hydrogen economy" proponent, but this makes more sense than their competitor's views.

Using "renewables" to make hydrogen/charge batteries doesn't necessarily make the outcome "green"

So the morale of the story is others are not sleeping at the wheel and are researching this market knowing fully well that the niche is in the big transporters with known routes+transports...

I wonder if there will be additional "green" credits for implementers?

But sometime the PR....

Is this a fake news ploy Anheuser tapped into to in an attempt to look environmentally friendly?
From what I understand, they own no trucks. Third parties transport and distribute the beer.

Werner Transportation has the Columbus, OH brewery contract to transport finished beer to the distributors
and the distributors are independently owned.

Skyactiv, Werner has all the empty transport as well from all of our glass plants to all of ABI's breweries. I'm sure InBed isn't buying trucks for Werner! I don't know about the retail side of their business, though.

Agreed. Burning anything to make the power is ridiculous.

Nothing is "green". Not fossil fuels, not "renewables", etc. Everything has some baggage. Its where you stick that baggage, and centralize/decentralize to better manage it or control release of certain pollutants.

IMO, fuels (liquids and propane/CNG) should be generally saved for mobility given energy density. H2 obviously has tremendous energy density, but the storage/stowage is more of a challenge. Delivery trucks that have a higher use and less downtime would be a better user than, say, a passenger car where some of mine might not get refueled for 6 months.

Some people would poop in their drinking water since its easy and cost effective...

I also have to laugh a bit at those who would want to play ostrich on the basis of component tech not being ready, yet also complaining about trying to develop and push the component tech that is the foundation of new approaches.

Very much on the same page...the fuels with the highest utility should be transport fuels has been my premise for my entire engineering career.

That is significantly more than a normal diesel truck.
