Aernata
Aernata produces clean methanol fuel from industrial CO2 emissions, converting waste carbon into a storable, transportable energy carrier for sectors where electrification is difficult. The company's catalytic process yields approximately 14.5 GJ of fuel energy per tonne of CO2, with a transparent energy accounting methodology published on its website. Aernata targets industrial emitters and shipping companies seeking low-carbon liquid fuel alternatives.

Problem
Industrial emissions release large volumes of carbon dioxide into the atmosphere, contributing to climate change while the world still depends on fossil fuels. Captured CO2 is often stored rather than used productively, and sectors like long-distance shipping lack viable electrification options, leaving a gap for low-carbon liquid fuels.
Solution
Aernata produces clean methanol fuel from industrial CO2 emissions, converting waste carbon into a usable energy carrier. The company uses a catalytic process where CO2 reacts with hydrogen to produce methanol and water, yielding approximately 14.5 GJ of fuel energy per tonne of CO2. This approach provides a practical pathway for reducing atmospheric carbon while generating storable, transportable fuel that can serve applications where direct electrification is difficult. Aernata's website also includes live atmospheric carbon counters for Earth and Mars, demonstrating the scale of CO2 available for fuel conversion and communicating the company's technical methodology.
Target Audience
Primary customers are industrial emitters seeking to reduce their carbon footprint while generating revenue from waste emissions, as well as shipping and logistics companies looking for low-carbon liquid fuels.
Features
- Converts CO2 to methanol via the reaction CO2 + 3H2 → CH3OH + H2O, producing roughly 0.728 tonnes of methanol per tonne of CO2
- Tracks real-time atmospheric CO2 levels using NOAA global monthly mean data (426.10 ppm as of July 2026) and projects figures for both Earth and Mars
- Calculates fuel energy yield at approximately 4.02 MWh per tonne of CO2, based on methanol lower heating value
- Provides transparent energy accounting that compares the 51–53% fuel-energy-to-electrolysis-electricity ratio and discloses excluded production costs
- Uses published data sources including NOAA, NASA, DOE, and IPCC references for all calculations
