Researchers Develop a System capable of Capturing 99 Percent of CO2 from Air, thus, boosting Carbon Capture and Storage Market
Pollution is the single most significant area of concern for humankind today. It is at the center of numerous world problems and needs to be urgently addressed. Carbon Capture Systems are one consistently growing industry aimed at similar objectives and could answer numerous pollution-related disadvantages.
A research team, in recent research, used a unique electrochemical device fueled by hydrogen. In this manner, they could absorb 99 percent of carbon dioxide from the air. The model is a big step forward for Carbon Capture and Storage Market, and it could help bring more ecologically friendly fuel cells to market.
Researchers have improved HEM (Hydroxide Exchange Membrane) fuel cells for a long time. The approach must be a cost-effective and environmentally friendly alternative to today's acid-based fuel cells in order to work. The issue of HEM fuel cells, on the other hand, has kept them off the road. Carbon dioxide in the air is extremely harmful to the cells. In other words, carbon dioxide makes it impossible for a HEM fuel cell to breathe.
This flaw affects the efficiency and performance of the fuel cell by up to 20%. Hence, effectively making it no better than a gasoline engine. For more than 15 years, research groups have been looking for a solution to the carbon dioxide conundrum.
The study team now has an electrochemical device that looks like a standard filtration membrane for separating gases. Nevertheless, it has the ability to continually pick up minute amounts of CO2 from the environment. Similar to a complex method like an electrochemical system.
The team built the devices with their wires embedded inside the membrane. Hence, creating a shortcut for carbon dioxide particles to go from one side to the opposite one. It also allowed the team to come up with a small-volume, helical module with an enormous surface area. The statement denotes that they now have a smaller container that can filter more air at once. Further, it is also practical and cost-effective for fuel cell applications. The team chose to have a few componentscomponents as it meant lower costs and a simple way to scale up for the market.
According to the findings, a mere two-inch-by-two-inch electrochemical cell can eradicate 99 percent of the carbon dioxide found in the air. Most importantly, it can be done while it is moving at a rate of roughly two liters per minute. The researchers believe an early prototype spiral device can filter 10 liters of air per minute, thereby removing 98 percent of carbon dioxide.
The electrochemical system is fueled by hydrogen. Hence it could be employed in airplanes and buildings where air recirculation is needed as an energy-saving solution as the hydrogen economy develops.
