CCS - Carbon Capture and Storage

[nwdiver]

As usually bandied about, 'CCS' is not net removal of CO2, it is low(er) emission fossil combustion.

It could be. It's just a matter of cost and whether you're capturing CO2 from power plant effluent or the atmosphere. If someone wants to pay $10 for a gallon of gasoline so $7 goes toward removing 15kg of CO2 from the atmosphere (10kg for the gasoline and 5kg for the energy needed to remove the 10kg). I'm ok with that as long as this is 'permanent' sequestration where the carbon is bound in rock not just underground in a gas pocket.

Good description of the outrageous opportunity cost, and why CCS is a numbskull idea

I think we need to make a distinction between tech solutions to hide current fossil fuel emissions and enhancement of natural processes which remove historical emissions.

Yeah ... they should just give you their work for free and thank you.

The way I see it, 400 ppm of CO2 in the atmosphere isn't sustainable, we already are melting most of the arctic ice as is. We need to get back to preindustrial levels (~270 ppm) of CO2 in the atmosphere as fast as possible. It will take a trillion new trees (at about a ton of carbon each), or some industrial process to do so, plus cutting the vast majority of fossil use to zero.

I strongly commend Elon for putting money on this.

Facebook is not the product. You are. Facebook is just a bait to collect your personal data. You are not the customer. Companies that purchase the data are.

Given that Everything Elon Does Is About Mars, remember that carbon capture will be important for Mars. The atmosphere is mostly carbon dioxide.

Helpful chart. I was trying to educate my Dad about why co2 is a problem on earth / why fossil fuels co2 is a problem, and he said the atmosphere is so big, man couldn’t have much effect. If you look at the chart and round to the nearest %, nitrogen, oxygen, and Argon make up 100% of atmosphere but these gasses do not trap heat.

Maybe... but the atmosphere on Mars is SUPER-thin. ~10mBar compared to ~1000mBar on Earth. And the objective on Mars isn't to remove CO2, it's to make CH4. Elon would probably like to add some CO2 to the atmosphere to make Mars a bit warmer. The atmosphere may not be the best source of C to make CH4.

True.

But, probably a good idea to have the removal solved before they start adding.

@nwdiver 's table really highlights just how inhospitable Mars is to humans.
No oxygen gas, and just about only carbon monoxide and CO2.

Musk wants to colonize a circa 1970's car exhaust pipe. If Mars also has some SoX it will be perfect.

There's actually a tiny amount of oxygen in the atmosphere.

That doesn't even mention the radiation and toxic soil.

It's typical Musk, though: as long as you have energy and the elements, it just needs engineering.

Every resource problem can bereduced to just add energy
