Carbon-based Energy Carrier Research Team
We are engaged in the research and development of energy (hydrogen) storage technologies based on interconversion between CO2 and formic acid/methanol, for CO2 utilization.
- Development of highly efficient catalysts that enable formic acid/methanol to be produced through carbon dioxide reduction (i.e., hydrogenation, electro-reduction), and that allow hydrogen to be produced from formic acid
- Investigation into technologies for producing high-pressure hydrogen from formic acid
Research Team Leader / Greetings
Facilities and infrastructure are crucial for the implementation of energy carrier technology using formic acid/methanol. We need the help of many different industrial partners in our research going forward. We believe that these collaborations will provide new technologies for generating high-pressure hydrogen from formic acid, and for supplying it to fuel cell vehicles (FCVs).
The aims in this team are development of highly efficient catalysts for interconversion between CO2 and formic acid/methanol (i.e., hydrogenation, electro-reduction, and dehydrogenation) and the high-pressure reaction process.
Production of Formic Acid and methanol by Reduction of CO2
The catalyst that we have developed showed the highest performance for CO2 reduction (hydrogenation, electro-reduction) to formic acid and methanol. These catalysts can convert CO2 with high energy efficiency under mild reaction conditions.
High-Pressure H2 Production from Formic Acid
The high-performance catalysts which can supply high-pressure (> 1000 atm) and CO-free H2 by heating (<100 oC) of formic acid was developed. In addition, gas-liquid phase separation can easily separate of CO2 from the high-pressure system. The high-pressure H2 production from formic acid is original AIST’s technology.
