This is a breakthrough in the fight against climate change. The team of engineers from University Duval-a placed their faith in an old idea, creating something that’s never been done before: an electrochemical system powered by hydrogen to capture 99% CO2 from the atmosphere with high efficiency!
The new method may also make it possible to commercialize more environmentally friendly fuel cells shortly.
The development of a new system has been detailed in an article published by Nature Energy.
The researchers behind it were challenged with setbacks while working on another research project, but they eventually came up against the right solution and developed something that can be used as-is or tweaked for other purposes after testing different versions over time – which is unusual because most projects don’t give you much feedback during their infancy phase!
The development of this new technology is the next step in increasing efficiency for hydroxide exchange membrane (HEM) fuel cells, which are much cheaper and more environmentally friendly than traditional acid-based cells.
The team discovered that HEM fuel cells are extremely sensitive to carbon dioxide in the air, which makes it difficult for these batteries to work properly.
The HEM fuel cell’s weakness is its sensitivity to carbon dioxide. Without enough of this gas, batteries won’t be able to work properly and the team will have yet another obstacle in their path!
Researchers have been working tirelessly to find a solution for how carbon dioxide can be used as an advantage. After all, it is the most dangerous substance in existence! However, researchers now believe they’ve found one–and its name is hydrogen gas cells or HEM fuel cell technology.
Hem chemistry isn’t new; however, what these scientists discovered was that placing small amounts of minerals close together at high pressures will create basic materials from which anything else might arise…
When the researchers dug into how these fuel cells worked, they discovered that not only were there numerous ways for them to capture carbon dioxide and other gases in our atmosphere. The technology was extremely effective at separating those molecules from each other on their side of this device!
To make it easier for their cells to operate, the team placed a carbon dioxide separator upstream from its fuel cell stacks. This is done by taking advantage of this built-in “self-purging” process found in HEM fuel cells and using an innovative design that allows them maximum power output with less waste product!
“It turns out that our strategy is extremely effective. If we have the right design and configuration, we can remove 99 percent of the carbon dioxide from the atmosphere in a single pass “Yushan Yan, the study’s principal investigator and a University of Delaware professor, said.
The team’s new, more compact system is capable of filtering larger volumes of air than the early prototype. It has been claimed that this soda can-sized device can remove 98% or CO₃from from entering your home in just one hour!
They discovered that a smaller electrochemical cell measuring 2 inches squared and flowing at an incredible rate of approximately two liters per minute could be used to continuously remove roughly 99% of the CO2 found in the air as it flows through.
They found that a small electrochemical cell measuring 2 inches squared and flowing at two liters per minute can remove roughly 99% of the CO2 in the air passing through it.
The prototype developed by the team is intended to scrub CO2 from a vehicle’s exhaust, but it has the potential of being used in other applications such as aircraft and spacecraft.
Despite the potential for improving carbon capture overall, some scientists have expressed concern that it will not be enough to avert a global climate crisis.
Scientists at the United States Center for International Environmental Law have labeled carbon capture a “dangerous distraction” that will only delay our transition away from fossil fuel consumption.
The new carbon capture facility will be able to remove up to 1 million tons of CO2 from the atmosphere per year and its construction has been approved by Scottish ministers. It’s set for completion within five years!
