Even if proposed for vicarious motives, the technology as such may still be the right way to go. From an environmental perspective, CO2 sequestration for EOR (enhanced oil recovery) makes little sense, other than reducing the carbon footpri

Sequestring CO2 is a huge scale problem, and all solutions have significant flaws. Forests require vasts amounts of land, and storage is only assured as long as nobody decides to chop down the forest for other more pressing purposes (looki

If you look at the weight of the tech product (phone) in isolation, you are correct although not in a very meaningful way. If you look at the amount of physical material that went into the process leading up to producing that product, the

Underground saline aquifers are an excellent place to store CO2, and worldwide storage space is estimated to be orders of magnitude above what is ever going to be needed. Also, keep in mind that CO2 is not stored as a gas, but in dense phas

For any mitigation solution, you have to ask 3 questions 1) How much does it cost 2) How much space does it require 3) How does it scale Planting trees performs excellent on (1) but terribly on (2) and (3). According to Bill Gates' re

Theoretically yes, although reasorbtion of CO2 takes a long time.

This is a place where carbon capture and storage would be a natural fit. Seriously. Cement is but one example of industrial processes that inherently release large amounts of CO2 even if we were to go 100% renewable energy-wise. Applying

That's what geological storage is all about. After all, the carbon came from the ground in the first place.

People may have different motivations for promoting CCS (carbon capture and storage). However, the underlying motivations for a subgroup of those promoting a technology shouldn't be a reason for dismissing the technology itself. I agr

Quite possibly, and in any case I did not have many illusions that we'd actually catch that ship. But I am not sure whether this particular news item shows that anything has really changed in terms of policy. France has been bombing I

If IS takes the pain to fund and coordinate something like this, it is surely because they want to obtain something. If the attack would not change status quo in any way, there would be no reason to invest time and resources in carrying it

You make a lot of claims. Mostly unsubstantiated. I do not see a point in engaging. And by the time the Dutch flee the Netherlands, it's too late to talk I'm afraid.

Any non-expert has a very limited capability of reviewing any significant fraction of published literature on such a vast field in detail, yet alone understand it or put it into proper perspective. Therefore, we (me, you and the parent post

Hi, I didn't really expect an answer, so thank you for giving one anyway. From what you write, I get the impression that could be described as a "slippery slope" kind of situation, which I can understand. I don't know

Well, I for one would be genuinely interested in how someone working in a field that I personally (and many with me) do find morally reprehensive (whether it be gambling, drugs, weapons, fossile fuels...) think about their role in the big p

The CO2 content of the exhaust from a coal-fired power plant is (fortunately) many orders of magnitude higher than what's found in the atmosphere. It would be much cheaper to capture it at the source. But even that is still considere

The atmosphere water content is self-regulating, since it works as a cycle (water evaporating, condensing and raining down, with the atmospheric content mainly regulated by how much vapor the air can hold). Not so with CO2. There is no si

Even if done at an industrial scale, it would serve no purpose from a climate perspective. Adding CO2 to a drink does nothing to get rid of it. Once the drink is consumed, the CO2 is right back out there. You only delay the release into

The issue of intermittency is in my opinion vastly undercommunicated in public debate about renewable energy, at least in Europe. A diagram like this [1] can be used to illustrate the issue. Although this diagram is from a hypothetical UK
