Carbon capture and storage technology8/15/2023 ![]() Atwater says “to reach our condition of sustainable level of carbon in the atmosphere below our current levels and back towards pre-industrial levels, we’re going to need to decarbonize and electrify everything that we can.” But for industries that are “almost impossible to decarbonize,” storage opens up an opportunity to put those emissions to good use. These techniques are sometimes shrouded with controversy-namely because many argue that capture and storage lets fossil fuel companies off the hook for their giant carbon footprints. Those are the things that we make at the gigatonne scale.” “The big markets are for things like fuel, cement, and steels. A net-zero energy system requires a profound transformation in the way we produce and use energy that can only be achieved with a broad suite of technologies. “Carbon negative technologies, unless you’re going to just pump that carbon dioxide underground that you’ve captured, they’re going to have to create new products like fuels, specialty chemicals and materials,” says Atwater. The strategy is to trap carbon dioxide where it is produced at power plants that burn fossil fuels and at factories so that the greenhouse gas isn’t spewed. There’s also no large-scale infrastructure supporting their growth and expansion. The possibility of capturing carbon dioxide greenhouse gas (CO 2 ), an approach known as carbon capture and storage (CCS), could help mitigate global warming. Most anti-carbon tech are in their infancy. “There’s literally gigatonnes of demand for carbon credits, and there’s only kilotonnes of capacity.” ![]() “We simply don’t have enough technologies to meet the demand. ![]() While carbon credit markets are emerging across the corporate sector, right now, there’s a gap between demand and capacity for storage methodologies. “There’s no worldwide agreed-upon price of carbon per tonne at the moment, which is one of the problems.” ![]() “If you’re simply going to sequester carbon, it requires citizens and leaders of advanced industrial societies to agree to basically tax themselves to underwrite the cost of storing that carbon,” says Atwater. Meanwhile, a huge issue for carbon capture and sequestration technology is the price tag. To keep a big forest-based carbon sink going, plants will have to be continuously harvested and protected from decay. “Once they reach ‘steady state’ (a mature forest, for example), the rate of carbon dioxide uptake due to growth is not much larger than the rate of carbon dioxide emissions due to respiration from living plants and decomposition of ‘dead’ biomass.” Also, new forests only remove significant amounts of carbon while the forest, or kelp forest in the ocean, is growing, Kelemen explains. ![]()
