Takasu Lab
Machine-translated · View original
The lab pursues decarbonization through turning CO2 into a resource, along with hydrogen and ammonia technologies.
AboutAbout the lab
Creating the future with energy chemistry
The Takasu Lab studies energy conversion and storage technologies aimed at achieving carbon neutrality.
It develops electrolysis cells that convert carbon dioxide into resources and absorbent materials that capture carbon dioxide.
It also works on metal membranes that extract hydrogen, solid absorbent materials that store ammonia, and heat storage materials.
The lab began its activities in April 2022 and advances its development in collaboration with companies, universities, and research institutions.
Key terms
- Carbon neutrality
- Balancing the greenhouse gases emitted with the amount absorbed so that the net amount is zero
- Solid oxide electrolysis cell
- A device that uses a ceramic that conducts oxygen ions at high temperatures to decompose gases with electricity. Abbreviated as SOEC
- Hydrogen separation membrane
- A membrane that lets only hydrogen pass from a mixed gas so that it can be extracted

ResearchResearch themes
The lab conducts broad research in energy-related chemistry and develops energy conversion and storage technologies for achieving carbon neutrality. It also launches new themes through joint research on an ongoing basis.
*Illustrative imageMetal-Supported Solid Oxide Cells
To convert carbon dioxide into resources efficiently, the lab develops solid oxide electrolysis cells (SOEC) that decompose it directly. Adding a metal support as a new layer gives the cell strength, with the aim of making large-area cells, which were difficult with ceramics alone.
*Illustrative imageAdvanced Metallic Hydrogen Separation Membranes
These membranes use the gaps between metal atoms as an "atomic sieve" that lets only hydrogen pass from a mixed gas. The lab develops technology to produce inexpensive, high-purity hydrogen by thinning a palladium alloy layer and combining it with a nickel support.
*Illustrative imageAmmonia Storage Materials
Ammonia, which is expected to serve as a carbon-free fuel, is toxic and corrosive, so safe storage is a challenge. The lab develops materials that store ammonia in a solid absorbent that reacts with it, and release it by applying low-temperature heat such as waste heat.
