I don't think so. Building an electric car emits a ton of CO2 as well. The figure that is often used is that building your car generates just as much CO2 that what it will generate during its lifetime of driving. So even if your truck runs 100% on renewable energy (and that's a big if, not to mention that creating this system also generates pollution before becoming green), retrofitting existing vehicles with technol…

That figure is flat-out wrong, though. It's a myth.

Can you link to an analysis?

Making electric trucks makes more sense. Then you can centralize the CO2 collection to the power plants and make it much more efficient.

And building a regular fuel car doesn't? (Assuming we need to build some kind of car anyway?)

"Electric cars are bad for environment because of building them and producing batteries" is plainly just a myth.

Why do you assume that, given the parent comment explicitly talks about retrofits?

That’s pure fiction. Even large batteries (100+ KWh) pay for their manufacturing emissions within a few years.

A car is a bit more than a large battery.

Seems like this might be a better solution for shipping than for trucks. Batteries are not really a viable solution for shipping, except on short routes. They're probably stuck with hydrocarbon fuels, but this might work, and the extra mass of CO2 carried wouldn't really be a big deal for a ship. Probably won't work with current dirty bunker fuel though, as I expect that contains too many contaminants; it would need the fuel to be cleaned up a lot first so I wouldn't expect the shipping industry to be overly enthusiastic.

Here’s a comprehensive study from the Union of Concerned Scientists.

With a carbon tax. It will automatically make fossil fuels more expensive, while this device produces a fuel not subject to the tax.

Carbon tax is a good idea. But it's not happening! Writing proposals, calling representatives, signing petitions and voting isn't helping. I mean, how do we actually make it happen?

> voting isn't helping

Because the will of the people is in the other direction. At this point, its a matter of convincing the greater public of the evidence.

People are stubborn and difficult to convince. And you need to convince roughly half of the voting population (maybe ~50-million people) before things happen in the USA. That's how democracy works.

There's also a power-imbalance that gets somewhat political: how smaller states have 2 senators and therefore control the vote despite having a very small population. Convincing those people is more important, because their vote matters more than most people.

200,000 Wyoming residents have the voting power of 700,000 California residents, due to how Senators work.

77% of semi truck routes are 250 miles or less, a distance easily covered by today’s EV technology.

You’re manufacturing a car either way aren’t you?

What fraction of the total semi truck traveled miles are on those short routes?
