A lab advancing CO2 separation, capture, and utilization from the perspective of exergy.
AboutAbout the lab
Rethinking how to reduce CO2 through the quality of energy
The Takao Lab conducts research from the perspective of exergy engineering, aiming to reduce CO2 emissions in power and energy systems.
Centered on CO2 separation, capture, storage, and utilization, the lab studies systems that produce energy and materials simultaneously.
The lab aims to make technologies that prevent CO2 from being released into the atmosphere practical in society, and to contribute to carbon neutrality in industry by 2050.
The lab is developing concrete made from seawater and CO2, and a technology that fixes CO2 by accelerating rock weathering.
Key terms
- Exergy
- The portion of a given amount of energy that can actually be extracted as work; a quantity that represents the 'quality' of energy
- Carbon neutrality
- Balancing the carbon dioxide emitted with the carbon dioxide absorbed or captured so that the net amount is zero
- Enhanced rock weathering
- A method that speeds up weathering by, for example, crushing rock into fine particles, so that atmospheric carbon dioxide is fixed as minerals

ResearchResearch themes
The Takao Lab studies systems that produce energy and materials simultaneously from the perspective of exergy, centered on CO2 separation, capture, storage, and utilization. It places emphasis on making the technologies it develops practical for real-world use in society.
*Illustrative imageConcrete Made from Seawater and CO2
The lab developed 'WMaCS,' a concrete made only from seawater and CO2. It reacts magnesium in seawater with CO2, fixing the CO2 while turning it into a construction material.
*Illustrative imageCO2 Fixation by Enhanced Rock Weathering
The lab leads the development of 'A-ERW,' a technology that artificially accelerates rock weathering to fix CO2 as minerals. Weathering is a natural phenomenon that normally proceeds slowly, and the idea is to speed it up.
*Illustrative imageAmine Absorbents for CO2 Separation and Capture
The lab is in charge of evaluating materials for amine absorbents that extract CO2 from exhaust gas. It also investigates how oxygen concentration and the length of exposure to high temperatures affect the degradation of the absorbents.
