Episode notes

In this episode of Earthlings 2.0, we speak with Alex Ip, co-founder and CEO of CERT Systems. CERT is a Canadian startup developing an electrochemical process that converts captured CO₂ into high-value chemicals, such as ethylene, using only electricity and water. Alex explains why these chemicals are so foundational to modern life, and why they’re also responsible for a significant share of global emissions. We unpack how CERT’s room-temperature “CO₂-to-chemicals” process works, what it means to replace both fossil fuel energy and feedstocks, and how circular carbon feedstocks could reshape supply chains on Earth, and maybe even enable local manufacturing on Mars.

Editor's Note: This episode was recorded and edited before the National Renewable Energy Laboratory was renamed to the National Laboratory of the Rockies

Key Points:

Chemicals are a major but overlooked emissions source – Products like ethylene, ammonia, and methanol are essential to modern life yet account for a significant share of global greenhouse gases, making chemical manufacturing a critical and often ignored sector for decarbonization.
CERT turns CO₂ into chemicals at room temperature – Using electrochemistry instead of heat, CERT’s process converts CO₂ and water into valuable chemicals like ethylene using only electricity, eliminating fossil feedstocks and enabling a low-temperature, modular approach.
Circular feedstocks can reshape supply chains – As CO₂ capture scales from point sources today to direct air capture in the future, chemical production could become more distributed, climate-aligned, and locally sited, breaking dependence on fossil infrastructure.
