Transforming Industrial Emissions from Liability to Asset

January 29th, 2026: KENTECH Electrode Converts Diluted CO2 in Single Step

Overview

For decades, carbon capture has faced a fundamental problem: systems designed to grab CO2 from industrial exhaust typically require a pure, concentrated stream of the gas to function. Real-world flue gas—the exhaust from power plants and factories—is a messy cocktail of nitrogen, oxygen, and trace pollutants. Most conversion technologies simply cannot handle it.

A team at South Korea's KENTECH has now demonstrated an electrode that captures and converts diluted CO2 in a single step, producing formic acid directly from simulated industrial exhaust containing just 15% CO2. The three-layer electrode performed where competing systems failed entirely—and even worked at atmospheric CO2 concentrations around 400 parts per million. The advance transforms the economics: instead of paying to separate CO2 before converting it, industrial emitters could potentially produce a $700-million-per-year commodity chemical directly from their smokestacks.

Scenarios

1

Industrial Pilot Plants Demonstrate Commercial Viability by 2030

Discussed by: Korea Institute of Science and Technology (KIST) researchers in technoeconomic analyses; industry analysts covering the CO2 utilization sector

KIST has announced plans to complete a 100-kilogram-per-day pilot plant by 2025, with process verification leading to potential commercialization by 2030. If the KENTECH electrode architecture can be scaled while maintaining its performance advantage in diluted CO2 streams, industrial facilities could begin retrofitting smokestacks with integrated capture-conversion systems. The key variable is whether the technology maintains its efficiency edge at industrial scales with real—not simulated—flue gas containing trace impurities.

2

Cost Parity with Fossil-Derived Formic Acid Achieved

Discussed by: National Renewable Energy Laboratory (NREL) technoeconomic analyses; Angewandte Chemie scale-up studies

NREL researchers have identified pathways to cost parity with conventional formic acid production when renewable electricity costs fall to 2.3 cents per kilowatt-hour or below. As solar and wind costs continue declining, electrochemical CO2 conversion could become economically competitive without subsidies. This would transform carbon capture from a compliance cost into a profit center, potentially accelerating adoption across heavy industry.

3

Hydrogen Economy Drives Formic Acid Demand Surge

Discussed by: Energy analysts at VoltaChem consortium; fuel cell researchers; International Energy Agency hydrogen reports

Formic acid stores hydrogen at higher volumetric density than 700-bar compressed tanks—the current industry standard. If hydrogen fuel cell vehicles and industrial applications scale as projected, demand for safe, liquid hydrogen carriers could multiply. Formic acid produced from captured CO2 would offer both the storage medium and a carbon-negative production pathway, potentially creating a multi-billion-dollar market that does not currently exist at scale.

4

Technical Barriers Stall Scale-Up Beyond Laboratory

Discussed by: ACS Environmental Science & Technology Letters reviews; academic researchers documenting scale-up challenges

The gap between laboratory demonstration and commercial deployment has proven difficult to bridge for electrochemical CO2 conversion. Catalyst degradation, electrode fouling from real-world impurities, and the challenge of stacking multiple cells for industrial output could limit the technology to niche applications. The KENTECH advance may remain a scientific achievement that does not translate to widespread deployment if manufacturing and durability challenges prove intractable.

Historical Context

Sleipner CCS Project (1996)

September 1996 - Present

What Happened

Norway's Sleipner gas field began injecting CO2 separated from natural gas production into a sandstone formation beneath the North Sea. The project was motivated by Norway's 1991 carbon tax, which made storage cheaper than venting. Over 23 million tonnes of CO2 have been stored through a single well.

Outcome

Short Term

Proved that large-scale CO2 injection into geological formations was technically feasible and that stored CO2 behaved predictably underground.

Long Term

Became the global reference case for carbon storage, informing regulations and providing the monitoring data that subsequent projects rely upon. However, it also showed that carbon capture remained limited to facilities with concentrated CO2 streams—the dilution problem the KENTECH research addresses.

Why It's Relevant Today

Sleipner demonstrated storage works, but required separating CO2 first. The KENTECH electrode potentially eliminates that separation step, addressing the economic barrier that has limited capture technology deployment for three decades.

Haber-Bosch Process Commercialization (1913)

1909-1913

What Happened

German chemists Fritz Haber and Carl Bosch developed a method to synthesize ammonia from nitrogen and hydrogen at industrial scale. The process required high pressures and temperatures that seemed impractical until Bosch engineered equipment capable of sustained operation. Within decades, synthetic fertilizers transformed global agriculture.

Outcome

Short Term

BASF built the first commercial plant in 1913, producing 30 tonnes of ammonia daily. The process enabled Germany to produce explosives during World War I despite being cut off from natural nitrate sources.

Long Term

The Haber-Bosch process now produces fertilizer supporting roughly half of global food production. It demonstrated how industrial chemistry can transform atmospheric gases into foundational commodities.

Why It's Relevant Today

Like Haber-Bosch converted atmospheric nitrogen into useful chemicals, CO2 conversion technology aims to transform waste emissions into valuable products. Both required solving engineering challenges that initially seemed insurmountable at industrial scale.

Solar Photovoltaic Cost Collapse (2008-2024)

2008-2024

What Happened

Solar panel costs fell from roughly $4 per watt in 2008 to under $0.20 per watt by 2024—a 95% decline driven by manufacturing scale, incremental improvements, and competition. Technology that seemed economically marginal became the cheapest source of electricity in most of the world.

Outcome

Short Term

Early government subsidies in Germany and feed-in tariffs in multiple countries created initial market demand that drove manufacturing scale.

Long Term

Solar became cost-competitive without subsidies, deployment accelerated exponentially, and the technology reshaped energy planning worldwide. Electricity costs fell low enough to enable electrification of previously fossil-dependent processes.

Why It's Relevant Today

Electrochemical CO2 conversion currently faces the same economic challenge solar faced in 2008—technically proven but too expensive to compete. NREL analysis suggests cost parity is achievable at renewable electricity prices of 2.3 cents per kilowatt-hour, a threshold approaching in favorable locations.
