This is not the world we want to see, this is not at all the world our future generations want to live in. the world we conquered with technology want to change its way from developed to sustainable developed one. But question arises what makes this Sustainable development which is just limited in some papers of the books to actions.
Is there any technology that can gift us a world that is safe and give us hope to sustain. Answering all these questions a technology came out naming itself as CARBON ENGINEERING
Saying that ‘Yes our technology can be a last hope to humanity’.
As the world today is being highly affected by the imbalanced poisoned gases released,
Among them carbon dioxide taking the major role became one of the biggest culprit for climatic catastrophe to the global warming what if we take it back.
This is possible by using two major technologies one (DAC) directly capture the CO₂ from atmosphere and the other AIR to FUEL technology
Carbon Engineering’s DAC is not just the technology that has the ability to suck the c02 from air but it has become a cleaner to the world.
It does this in a closed loop where the only major inputs are water and energy, and the output is a stream of pure, compressed CO₂.
Coming to background in brief this DAC process starts with a “wet scrubbing” air contactor which uses a strong hydroxide solution to capture CO₂ and convert it into carbonate.
This carbonate solution is converted into small pellets of calcium carbonate by pellet reactor .These pellets, once dried, are processed in Calciner that heats to decomposition temperature, breaking them apart to release the CO₂ as a gas and leave behind solid lime or calcium oxide. This calcium oxide is hydrated in a slaker, and is then returned into the pellet reactor to regenerate the hydroxide capture solution, closing the chemical loop.
Coming to the technology, it found the way to recreate the world by sending this captured c02 underground so that we can regenerate the degrading fossil for future generations. This is the only technology to achieve industrial-scale carbon dioxide removal (CDR) as it flexible to any climate and geological conditions of a country. The captured, compressed CO₂ from DAC offers a wide range of opportunities not only to produce materials such as steel, concrete, fillers, and coatings but also chemicals such as plastics, industrial chemicals, fertilizers, and carbonates .
Instead of burying the CO2 this technology captures and plans to use it as an input to make synthetic fuels that can be a substitute for diesel, gasoline, or jet fuel. Creating synthetic fuels involves combining a carbon-based molecule, usually CO2, with hydrogen.
The resulting carbon intensity of fuels largely depends on the sources the electricity, the CO2, and the hydrogen. If the electricity and the CO2 are from fossil fuels and fossil fuel exhausts stream, and the hydrogen from steam of natural gas , then the resulting fuel is extremely carbon-intensive.but
If the electricity and the CO2 comes from renewable sources , and the air, and the hydrogen from solar-powered electrolysis, the resulting fuel is extremely low carbon.
Carbon Engineering wants to make such a very low-carbon fuels. The company calls the process “AIR TO FUEL”.
Getting the CO2 for the process from the air rather than from fossil fuel emissions and taking the responsibility to transform synthetic fuels from low-carbon to ultra-low-carbon is challenging for carbon engineering, as getting hydrogen from electrolysis rather than steam reforming natural gas is more expensive. Because, of a simple reason that natural gas tends to be cheaper than electricity.
This company may have solved one of the hardest problems in clean energy
If costs of the hydrogen are managed somehow, the next challenge is competing in a market specifically, a market in which the carbon content of fuel matters.
As of now, the current worlds governments set some (low-carbon fuel standard(LCFS) that requires some declination in the carbon intensity for the companies that sell fossil-based fuels so these companies have to source some lower-carbon fuels to offset them, this made a credit trading for carbon engineering.
As the carbon engineering is producing fuels with low carbon intensity it found government as its source for initial financing, funding. So at the end Carbon Engineering just needs a buyer for its initial fuels and a contract for some very cheap renewable energy,
Conclusion: the carbon engineering air capture technology has been stuck in a catfight between one group of people saying it’s a silver bullet and one group saying its bullshit. The truth is it’s neither.”
For now, DAC, in the form of AIR to FUEL, is the only way that has entered into the world which opened all its gate ways to avoid emissions from burning fossil fuels. Due to its flexible technology, there’s a potential for distributed production of air fuels everywhere. Every country could have access to its own source of what is effectively carbon-neutral oil. It will become one of the key remaining pieces of the decarbonization puzzle.
And finally, hoping a day to come where carbon prices are high, emissions are heading toward zero, and governments begin to spend serious money on negative emissions.
In the end, DAC, like most clean energy technologies, is neither a silver bullet nor bullshit. It’s just a promising development in a world that needs all the promising developments it can get.
