Biden administration earmarks $1.2 billion for two large-scale carbon capture projects

The Department of Energy is giving grants of up to $ 1.2 billion to two direct air capture (DAC) projects that aim to remove more than 2 million metric tons of carbon dioxide from the atmosphere every year. The agency says that's equivalent to the annual emissions of around 445,000 gas-powered cars. The DOE notes that the projects in Texas and Louisiana will "create 4,800 good-paying jobs" as well.

DAC employs a chemical process to separate CO2 from the air. Facilities can then store CO2 underground or put it into carbon-containing products like concrete that prevent the gas from getting back into the atmosphere.

These are the first commercial-scale DAC projects in the US. They'll each be capable of removing more than 250 times as much CO2 from the atmosphere than the current largest DAC location, according to the DOE. Occidental Petroleum subsidiary 1PointFive and its partners are building the Texas facility. The company's CEO says that, when the project is fully operational, it has the potential to remove up to 30 million tons of CO2 from the atmosphere each year.

The two projects are the first selections from the Regional Direct Air Capture Hubs program, which the Bipartisan Infrastructure Law funded. The aim of the program is to mitigate the impact of climate change by developing a nationwide group of large-scale carbon removal sites that will work in harmony with other efforts to reduce emissions.

The DOE says that, when it is sufficiently scaled up, DAC technology can help the US meet its target of neutralizing emissions by 2050. However, as Reuters notes, to reach the level of scale needed for DAC to have a big enough impact globally, it's imperative to reduce the costs involved quickly.

To that end, the agency has announced several efforts to lower the costs of DAC to below $ 100 for each net metric ton of CO2-equivalent by the end of the 2020s. It's funding 14 feasibility studies along with five engineering and design studies for projects that are in earlier stages. There's also a $ 35 million government procurement program in place for carbon removal credits.

To reach the Biden administration's goal of having a net zero emissions economy by 2050, the DOE estimates that between 400 million and 1.8 billion metric tons will have to be removed from the atmosphere and captured from emissions sources every year.

Water-soluble circuit boards could cut carbon footprints by 60 percent

German semiconductor maker Infineon Technologies AG announced that it’s producing a printed circuit board (PCB) that dissolves in water. Sourced from UK startup Jiva Materials, the plant-based Soluboard could provide a new avenue for the tech industry to reduce e-waste as companies scramble to meet climate goals by 2030.

Jiva’s biodegradable PCB is made from natural fibers and a halogen-free polymer with a much lower carbon footprint than traditional boards made with fiberglass composites. A 2022 study by the University of Washington College of Engineering and Microsoft Research saw the team create an Earth-friendly mouse using a Soluboard PCB as its core. The researchers found that the Soluboard dissolved in hot water in under six minutes. However, it can take several hours to break down at room temperature.

In addition to dissolving the PCB fibers, the process makes it easier to retrieve the valuable metals attached to it. “After [it dissolves], we’re left with the chips and circuit traces which we can filter out,” said UW assistant professor Vikram Iyer, who worked on the mouse project.

The video below shows the Soluboard dissolving in a frying pan with boiling water:

“Adopting a water-based recycling process could lead to higher yields in the recovery of valuable metals,” said Jonathan Swanston, CEO and co-founder of Jiva Materials. Jiva says the board has a 60 percent smaller carbon footprint than traditional PCBs — specifically, it can save 10.5 kg of carbon and 620 g of plastic per square meter of PCB.

Infineon has produced three different circuit board prototypes using the Soluboard framework. The company is currently only using the dissolvable PCB for demo and evaluation boards, and it says around 500 units are now in use. However, it’s “exploring the possibility of using the material for all boards” with an eye on expanding adoption over the next few years. Based on the results of stress tests, it also plans to “provide guidance on the reuse and recycling of power semiconductors removed from Soluboards” to lessen the chances of the salvageable parts from future production models going to waste.

US Department of Energy wants to dramatically reduce the cost of carbon capture technology

The US Department of Energy wants to accelerate the development of carbon capture technology. On Friday, the agency announced a program called Carbon Negative Shot. Part of its Energy Earthshots initiative, the goal here is to foster the development of carbon capture technology that can sequester CO2 at a cost of less than $ 100 per ton, and can be deployed at the gigaton scale. To put that in perspective, that much carbon is equivalent to the annual emissions of approximately 250 million cars.

“By slashing the costs and accelerating the deployment of carbon dioxide removal — a crucial clean energy technology — we can take massive amounts of carbon pollution directly from the air and combat the climate crisis,” said Secretary of Energy Jennifer M. Granholm. “With our Carbon Negative Shot, we can help remove the greenhouse gases already warming our planet and affecting our health — positioning America as a net-zero leader and creating good-paying jobs for a transitioning clean energy workforce.”

If it wasn’t clear already, the Energy Department has set an ambitious target. In September, Orca, the largest direct carbon capture facility ever, opened in Iceland. The plant will capture 4,000 tons of CO2 per year at a cost of about $ 600 per ton for bulk purchases. Chimeworks, the company that operates Orca, aims to reduce the cost to $ 300 or less per ton by 2030. That’s a long way away from the Energy Department’s goal of less than $ 100 per ton, but sustained and substantial support and investment from the government is exactly what could make that happen.
