Korea Institute of Power Analysis (KIER) has efficiently demonstrated the world’s largest gasoline energy technology expertise able to inherently separating carbon dioxide. They’ve additionally turn into the primary on the planet to make use of this strategy to efficiently generate steam for electrical energy manufacturing.
In typical gasoline energy technology, gas combustion releases carbon dioxide, a serious greenhouse gasoline, together with nitrogen and water vapor. As soon as emitted, CO₂ mixes with nitrogen from the air, necessitating specialised amenities to selectively separate and seize pure CO₂ for storage. This extra course of will increase energy technology prices.
To deal with this problem, chemical looping combustion (CLC) expertise is rising as an eco-friendly energy technology answer. Not like typical strategies the place gas reacts straight with air, CLC expertise delivers pure oxygen to the gas utilizing oxygen-carrying particles. These particles launch oxygen throughout combustion and later reabsorb it when uncovered to air, constantly repeating the cycle to maintain the method.
By leveraging this expertise, gas interacts solely with pure oxygen, eliminating any response with nitrogen from the air. In consequence, the combustion course of generates carbon dioxide and water vapor, due to this fact after condensation of water vapor, enabling direct seize with out the necessity for added separation. Moreover, not like typical combustion, which produces nitrogen oxides (NOₓ), a serious contributor to ultrafine particulate matter, this expertise operates by flameless combustion, drastically decreasing NOₓ emissions.
The analysis workforce, in collaboration with KEPCO Analysis Institute, developed a world-class chemical looping combustion (CLC) expertise. In 2023, they established a 3 MW-scale pilot plant, the biggest of its type globally, and carried out full-scale demonstration exams. Over 300 hours of steady operation, the expertise achieved a carbon dioxide separation and emission effectivity exceeding 96%, surpassing the earlier world benchmark of 94%.

Together with the profitable demonstration, the analysis workforce has additionally opened the door to commercialization. For the primary time on the planet, they’ve efficiently produced steam for energy technology utilizing chemical looping combustion (CLC) expertise. Whereas superior international locations such because the European Union, China, and the US have been conducting CLC expertise demonstrations, none have but achieved steam manufacturing.
If the demonstration scale of the expertise is small, effectivity is excessive, however warmth loss is critical, making it unimaginable to generate steam. Equally, if effectivity can’t be maintained whereas scaling up, steam manufacturing doesn’t happen.
Nevertheless, the analysis workforce has enabled steam manufacturing by growing course of design and operation applied sciences that reduce warmth loss whereas scaling up and by advancing large-scale manufacturing strategies for oxygen provider particles. This transition has moved the expertise from the realm of promising future improvements to the area of commercialization.
An financial evaluation of chemical looping combustion (CLC) expertise predicts that, in comparison with a traditional 100MW pure gasoline energy plant, it should generate an annual working revenue of 14.4 billion KRW and enhance energy technology effectivity by 4%.
Notably, CO₂ seize prices are anticipated to be diminished by 30% in comparison with present strategies, enabling the seize of over 150,000 tons of CO₂ per 12 months. This development is predicted to make a big contribution to attaining nationwide carbon neutrality objectives.
Dr. Ryu Ho-jung, the lead researcher of the CCS Analysis Division, acknowledged, “To attain nationwide carbon neutrality, it’s important to ascertain and function gasoline energy vegetation that incorporate revolutionary applied sciences akin to chemical looping combustion (CLC).
“We will continue to advance and demonstrate our technology to accelerate the commercialization of next-generation power generation solutions.”
