Direct Air Carbon Capture (DAC) technologies extract CO2 directly from the atmosphere. For DAC to be an effective solution, and not a burden on decarbonization efforts it needs to be designed correctly, meaning it must be scalable, affordable, and fossil fuel independent.
Current Barriers for a Successful, Affordable DAC Technology
Temperature-, pressure, and electro-swing DAC requires new manufacturing to scale
99.7% of New Carbon Free Energy is Intermittent, but a reliable grid connection creates emissions
Low DAC utilization leads to increased Capex costs, but firm power increases Opex
Solves this Challenge
Para‖‖el Carbon is developing the world’s most affordable direct air capture (DAC) process, relying only on water, wind, sunshine, and abundant minerals. Our technology fits seamlessly into a net-zero world, avoids increasing demand for fossil fuel extraction, and operates economically with intermittent renewable power. Importantly, its scalability enables profitable, gigaton-scale carbon removal, improves grid decarbonization economics, and promotes a circular economy.
Our process delivers cost-effective carbon management by combining geomimicry with electrochemistry. Many of Earth’s minerals (and organic matter) readily sequester CO2, but these systems are too limited by speed or scale to handle the excessive amounts of CO2 humans are injecting into the air. Para‖‖el Carbon enhances and accelerates ancient mineral reactions with modern electrochemical processing to solve the speed and scale challenge.
Para‖‖el Carbon’s patent-pending DAC system captures CO2 from air using minerals that transform their chemical structure while doing so. In order to regenerate our capture medium and to liberate and permanently store the captured CO2, these minerals are processed using aqueous, acid-base reactions. The acids and bases we use are produced by water electrolysis.
Our DAC technology is special: our electrolyzer also produces green hydrogen, which is an important tool for decarbonizing industries. By designing a product that integrates CDR with hydrogen production, we can double our climate impact.
Our project will utilize CO2 to create infrastructure materials from highly alkaline materials, by-products and wastes. We will also durably store CO2 via underground injection.
Through these pathways, we will store more than 2 gigatonnes of CO2 per year from the air by 2040.
