Flying Towards a Greener Future: United Airlines' Big Bet on Clean Air

United Airlines is taking a bold step towards reducing its carbon footprint. The company has invested in a cutting-edge technology that sucks carbon dioxide straight from the air. This isn't just about waiting for sustainable aviation fuel (SAF) to become more available. United Airlines Ventures Sustainable Flight Fund has put money into Heirloom, a company specializing in direct air capture (DAC). DAC is a game-changer. Unlike traditional methods that capture CO2 from specific sources, DAC grabs it right out of the atmosphere. Heirloom's technology uses the natural power of limestone to do this efficiently and at a low cost. This makes it a promising solution for removing carbon dioxide from the environment. United Airlines Ventures (UAV) is leading the charge with this investment. The fund, backed by over 200 million dollars and supported by 18 corporate partners, is all about finding profitable ways to decarbonize aviation. Andrew Chang, the head of UAV, sees carbon capture as a key player in the energy sector's growth. Heirloom's technology fits perfectly with United's goal of achieving net-zero emissions by 2050. United Airlines has made a deal with Heirloom. The airline has the option to buy up to 500, 000 tons of carbon dioxide removal. This CO2 can be used to make more SAF or stored underground permanently. This is United's third investment in carbon capture, but it's the first time they've backed a company that's commercializing DAC technology. Heirloom, founded in 2020, is already making waves. In 2023, they opened North America's first commercial DAC facility in Tracy, California. They're also part of Project Cypress, a big DAC hub supported by the Department of Energy. This project aims to bring large-scale carbon removal to Louisiana and create nearly 1, 000 new jobs. Heirloom's approach to DAC is straightforward: capture CO2 from the air and combine it with green hydrogen to produce SAF. This creates a circular carbon flow, reusing carbon already in the atmosphere and supporting the US workforce. The aviation industry is under pressure to reduce its carbon footprint. The International Air Transport Association (IATA) has been making progress towards net-zero emissions by 2050. However, the path to achieving this goal isn't straightforward. The industry needs to reduce emissions as much as possible and remove any remaining emissions that can't be eliminated. Heirloom's strategy involves two main buckets for DAC: one for SAF production and another for removing residual emissions. As the demand for SAF grows, so will the need for DAC to fill both buckets. This technology is crucial for handling the remaining emissions even after a full conversion to SAF. The aviation industry is facing a challenge. It needs to reduce its carbon footprint significantly by 2050. United Airlines' investment in Heirloom is a step in the right direction. However, the industry needs to do more than just invest in new technologies. It needs to think critically about how to implement these technologies effectively and ensure they have a real impact on reducing emissions.
