The Problem:
Producing sustainable fuels requires affordable, low-carbon CO2 and H2, but DAC and electrolysis remain costly ($600–1,000/t CO2, $4–7/kg H2) for feedstock generation. E-fuel projects face risks using point-source CO2 and struggle to co-locate low-carbon CO2 and H2. Parallel Carbon captures CO2 as a co-product to H2 production, delivering high-purity, low-carbon gases at the same site, targeting under $2/kg H2 and $200/t CO2 before 2030, even at sub-commercial scale.The Solution:
Parallel Carbon’s solution integrates DAC with a membrane-free water electrolyser to co-produce CO2 and H2 from renewable electricity, reducing capex while supplying feedstocks for e-fuels. The electrolyser also generates acids and bases for DAC use. Our DAC system operates passively using wind and convection, reducing energy demand and equipment size. Intermittent electrolyser operation on low-cost renewables, paired with passive DAC, delivers the lowest-cost CO₂ and H₂ with minimal resources.The Differentiator:
Our startup combines direct air capture and hydrogen production in one low-cost, integrated system. Unlike others, we use membrane-free electrolysis and passive mineral cycling to co-produce CO₂ and H₂ with minimal energy, land, and water use. This dual-output model offers two revenue streams and supports clean fuel production at scale.Biggest Achievement:
