Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

You keep jumping back and forth between biofuel and biomass. You can bury solid biofuel, you can pump liquid biofuel, both are stable if you put them somewhere without much oxygen

Biomass is something different... Do it right and you can just use it as fertilizer. Just grow a bunch of algae and spray it over dry land... It's that easy. It'll feed the soil, which locks up a lot of carbon back into the food chain. Stack wood in a desert, who cares. There's so many better ways to do this

And CO2 is a fucking gas. Yes, it's liquid under pressure or at low enough temp... But it does not stay that way! We live in Earth, and most cavities aren't able to stay pressurized without leaking

You fail to comprehend the concept or need for "sequestering". What you are talking about perpetuates the atmospheric carbon cycle. It does not decrease atmospheric carbon dioxide. The mass biodegrades, re-releasing the carbon. "Sequestration" locks that carbon out of the biosphere. You are not talking about sequestration.

You keep jumping back and forth between biofuel and biomass.

Biomass is the raw substance. Biofuel is processed biomass. Processing it into a solid fuel is relatively trivial by little more than compressing it under relatively low pressure. Processing into liquid fuels is far more complicated and energy intensive than CO2 capture after combustion. For sequestration purposes, biomass would not be processed into liquid fuel. Liquid biofuels would only be used for transportation purposes.

And CO2 is a fucking gas

Not at the depths and pressures we're talking about.

But it does not stay that way! We live in Earth, and most cavities aren’t able to stay pressurized without leaking

I think you need to revisit that misconception. The cavities we're talking about certainly are.

You can bury solid biofuel,

Not in the volumes necessary for atmospheric carbon capture, no, we cannot. Furthermore, solid biofuels are not stable, certainly not as stable as CO2.

At this point, you just seem obscenely delusional to me. What you're saying is so far beyond reason I don't even know where to start.

You are not informed enough to have an opinion on the topic. I'm sorry, you're just spewing nonsense, you need to keep your opinions to yourself

This does not surprise me. I mean, you suggested spraying carbon-rich "fertilizer" within the biosphere as a valid approach toward reducing atmospheric carbon.

Your basic understanding of the concept of "sequestration" is irreparably flawed.
