Overview of Direct Air Capture Technology
Direct air capture (DAC) is an emerging technology designed to remove carbon dioxide from the atmosphere, operating like a vacuum for emissions already produced. Investment in this area has increased, with substantial funding from both oil and gas companies and government initiatives, such as the Biden administration’s $1.2 billion allocation to direct air capture hubs. This technology evolves from a theoretical concept to practical applications, supported by significant attention from the policy and entrepreneurial sectors. Acknowledging that decarbonization alone is insufficient to address climate change, DAC presents a complementary solution to capture CO2 that cannot be eliminated through traditional means.
