Heirloom

Heirloom is on a mission to restore balance to our atmosphere. We are removing 1 billion tons of carbon dioxide by 2035, using natural processes to engineer the world's most cost-effective Direct Air Capture solution.

Naturally occurring minerals - alongside forests, soils, and the ocean - are one of our planet's most vital carbon sinks. Over geological timescales, carbon dioxide in the air and water chemically bind to these minerals and permanently turn to stone.

Our technology enhances this natural process, called carbon mineralization, to help minerals absorb CO2 from the ambient air in days, rather than years. By combining the best of engineering and nature, we can offer the most cost-effective and scalable Direct Air Capture solution in the world.

Company Summary   Our mission is to accelerate our planet’s transition to a carbon negative society. We will capture 1B tons of CO2 from the atmosphere by 2035 (equivalent of ~60M Americans’ annual emissions today), and build a multi-billion dollar business along the way. The problem we are solving is that according to IPCC, billions of tons of CO2 need to removed from the atmosphere (in addition to decarbonizing the entire economy) by 2050 to keep global warming to 1.5 °C, but current technologies are too expensive and not scalable to the volume necessary.   Unlike traditional engineered removal solutions, our Nature published technology combines the natural properties of minerals (carbon mineralization) with engineering to provide a low cost path to $50/tCO2 for Direct Air Capture (DAC), the cost at which carbon removal will be transformative.    Our early customers are corporations and other entities that need to reduce and offset their carbon emissions to meet compliance...

The Heirloom team is on a path to creating a sustainable, scalable, and economically viable carbon removal system. This technology - which requires a unique blend of geology, chemistry, industrial engineering, and process engineering -  doesn’t yet exist at the scales necessary to make a difference, so we need to build it ourselves.  We are looking to hire a dedicated chemical/materials engineer to assist in Heirloom’s R&D projects related to mineral carbonation. This position requires good communication, excellent attention to detail, and a strong desire to do hands-on work. You will have the opportunity to meaningfully contribute to Heirloom’s mineral carbonation research program.  What You Will Do Design and perform analytical testing using a variety of methodologies to assess the carbonation performance of mineral feedstock under varying conditions. Collect, interpret and analyze data, compile results, and prepare reports. Perform routine characterizations of mineral...
