Coal-fired power plants account for roughly 30% of global CO2 emissions. There might be a promising way to remove carbon dioxide from fossil-fuel power plant exhaust before it reaches the atmosphere in a simple, economical and potentially reusable material. Aluminum formate (ALF), can separate CO2 from the other gases coming from coal-fired power plants smokestacks and lacks shortcomings other proposed carbon filtration materials have. Made of two substances found easily and abundantly, creating enough ALF for wide use should be possible at a very low cost.
