Your essay offers a valuable perspective on CO2 removal from the top of the value chain, but it overlooks critical challenges at the operational level, leading to incomplete conclusions.

As an innovator at the bottom of the value chain, I tackle the chemistry and physics of carbon capture directly, manipulating molecules and measuring energy in joules. Every decision balances useful work against entropy. For the past three years, novel CO2 capture pathways have lacked support in the U.S., stifling innovation.  Climate venture capitalists offer little support, as they predominantly back technologies tied to U.S. DOE initiatives, overlooking innovative, thermodynamics-driven solutions outside this framework.

CO2 removal at the scale required would be the largest market in history, demanding unprecedented energy. Thermodynamic constraints make current capture technologies inefficient, as they destroy carbon exergy, rendering them unusable at scale.

The Biden administration’s Carbon Removal Moonshot failed by neglecting innovation and thermodynamic principles. Spending without technical grounding doesn’t guarantee success. Trump’s cancellation of these programs is defensible on technical merits.

You correctly note that U.S. energy innovation is being ceded to other nations. Abandoning exergy-destroying CO2 capture technologies could be beneficial if paired with robust support for next-generation methods that preserve and refine carbon exergy. Energy-efficient, cost-effective solutions are feasible now, but U.S. policy has sidelined innovation for the past three years.

Innovators like me are forced to seek funding elsewhere. I’m preparing two funding applications for Tencent—one for flue gas capture, another for direct air capture. If China values energy efficiency and thermodynamics, they could own my technology. Then, with aggressive development, they can dominate CO2 removal for decades.  This raises concerns: if China controls 80% of the CO2 removal market, will U.S. policymakers be willing to funnel billions of taxpayer dollars to them?

I urge those interested in large-scale carbon removal to study the thermodynamics of capture. My essays aim to clarify these issues, and I invite further discussion to drive meaningful progress.

Many of the Carbon capture solutions I’ve read about are energy intensive.

IF they powered by renewable energy, they can be a good thing. But if powered by fossil fuels, or the renewable energy used must be backfilled with fossil fuels, their benefit is minimal.

i hope you will discuss this in your series and also promote less fuel intensive solutions. I look forward to the remainder of this series!
