Harada Lab
Machine-translated · View original
A lab researching carbon-neutral materials and processes that capture CO2 and turn it into resources.

AboutAbout the lab
Keeping energy running without emitting CO2.
The Harada Lab conducts research aimed at establishing the next-generation carbon-neutral cycle.
The research is meant to curb global warming and make it possible to keep using energy in a sustainable way.
The lab works on highly efficient CO2 separation and capture, CO2-free hydrogen synthesis, and CO2 conversion using clean energy.
It combines materials development and chemical process design with computational science.
Key terms
- Carbon neutrality
- A state in which the CO2 emitted is balanced by the CO2 captured or absorbed, so that the total does not increase
- CO2 absorbent
- A material that takes in and captures gaseous CO2 and allows it to be released later
- Ionic liquid
- A salt made only of positive and negative ions that stays liquid even at low temperatures

The lab aims to establish a next-generation carbon-neutral cycle that curbs global warming and enables sustainable energy use. Through materials development, chemical process design, and computational science, it studies everything from CO2 separation and capture to hydrogen synthesis and CO2 conversion.
*Illustrative imageHighly efficient CO2 separation and capture
To separate and capture CO2 efficiently at low cost, the lab develops high-capacity, highly reactive CO2 absorbents such as core-shell nanoparticles and molten ionic oxides. It also works on designing chemical processes that use these materials.
*Illustrative imageCarbon-free hydrogen synthesis
Hydrogen synthesis without CO2 emissions is expected to be a clean way of producing energy with a small environmental burden. The lab is demonstrating a CO2 sorption-enhanced methane reforming process, in which selectively separating the reaction gases shifts the chemical equilibrium.
*Illustrative imageLow-energy CO2 conversion
This is a technology that converts CO2 emitted from fossil fuels back into useful chemicals using carbon-free energy, so that it can be reused. The lab is carrying out fundamental studies of a new electrochemical CO2 reduction that uses molten ionic liquids as the reaction medium.
