## Summary

Selected for two separate DOE DAC Hubs (Red Rocks + CALDAC). Breaking ground on commercial pilot in California in 2026. Geothermal-powered DAC cuts energy cost barrier.

## Company Overview

AirMyne is a direct air capture (DAC) company that uses geothermal energy to power its liquid sorbent CO2 capture process — addressing the largest cost driver in DAC by using low-temperature geothermal heat for sorbent regeneration rather than electricity. The company is breaking ground on a commercial pilot facility in San Joaquin County, California in 2026, with CO2 to be stored in adjacent Class VI sequestration wells.

AirMyne has been selected for two separate DOE DAC Hub programs: the Red Rocks DAC Hub and CALDAC — a rare dual-hub selection that signals strong government validation of its technical approach and team. DOE DAC Hub selection provides both direct funding and access to infrastructure partnerships (geological storage, monitoring, CO2 utilization) that accelerate commercialization timelines.

The geothermal co-location strategy is geographically specific but powerful where applicable: California's San Joaquin Valley has both geothermal heat resources and Class VI CO2 storage capacity in close proximity, making it one of the most cost-advantaged DAC sites in the US. If AirMyne's geothermal-powered process achieves its cost targets, it could undercut electricity-powered DAC alternatives by 40-60% at mature scale.

## Frequently Asked Questions

### What does AirMyne do?
Direct air capture using liquid sorbents regenerated by geothermal heat — eliminating the electricity cost that makes conventional DAC expensive, with California commercial pilot breaking ground in 2026.

### What DOE programs has AirMyne been selected for?
Two separate DOE DAC Hubs: Red Rocks DAC Hub and CALDAC — rare dual-hub selection validating AirMyne's technical approach.

### Why is geothermal DAC cheaper?
Sorbent regeneration (releasing captured CO2) is the most energy-intensive DAC step. Using low-temperature geothermal heat instead of electricity cuts this cost by 40-60% vs. electricity-powered DAC.

### Where is AirMyne's pilot facility?
San Joaquin County, California — co-located with geothermal heat resources and Class VI CO2 sequestration wells, one of the most cost-advantaged DAC sites in the US.

### What CO2 removal cost does AirMyne target?
AirMyne is targeting a levelized cost of carbon removal below $200/tonne CO2 at commercial scale — significantly cheaper than most liquid sorbent DAC approaches that estimate $300-600/tonne. The geothermal heat integration is the key cost reduction lever.

### Who are AirMyne's potential carbon credit buyers?
AirMyne targets large voluntary market buyers — Microsoft, Stripe Climate, Google, Shopify — that have made advance purchase commitments (APCs) for high-quality, permanent carbon dioxide removal. DOE's CDR Purchase Pilot Prize is another potential offtake pathway.

### What is Class VI well injection and why does it matter for AirMyne?
Class VI wells are EPA-regulated injection wells specifically permitted for geological CO2 sequestration. AirMyne's California pilot co-locates with Class VI sequestration infrastructure, enabling captured CO2 to be injected into deep geological formations where it mineralizes permanently over centuries.

### What does AirMyne's dual DOE DAC Hub selection signal?
Being selected for both the Red Rocks DAC Hub and CALDAC is exceptionally rare — most DAC companies are part of one hub. It signals broad government confidence in AirMyne's technical approach and team, providing access to federal funding, co-development partners, and geological storage infrastructure critical for commercialization.
