e-Fuel
e-Fuel (Methanol, Ethanol, DME)
In response to the escalating climate crisis, it is necessary to reduce the concentration of Carbon Dioxide in the atmosphere. However, the procedure needs to extend beyond merely capturing Carbon Dioxide. We must undergo a process called Carbon Dioxide Reduction, transmuting it into substances of added value. Methanol, formic acid, and ethanol serve as representative substances that can be produced through Carbon Dioxide Reduction. These substances, along with their derivatives, are collectively designated as 'e-fuel'.
e-fuel is a fuel that pursues net-zero emissions, produced by reducing carbon dioxide using green hydrogen generated from renewable energy sources. The utilization of these net-zero fuels allows conventional internal combustion engines to mitigate environmental pollution, and they can also serve as a viable energy source in sectors where electrification poses challenges, including large marine vessels and aviation. Ideally, employing e-fuel could establish a net-zero circular economy, in which the amount of carbon dioxide released into the atmosphere is outweighed by the amount captured during fuel production. Furthermore, e-fuel has garnered significant research interest due to its potential role as a hydrogen carrier, like ammonia and LOHC (Liquid Organic Hydrogen Carrier), thereby enhancing the feasibility of transitioning to a hydrogen economy.
In pursuit of this environment-friendly societal model, our laboratory is engaged in research on thermochemical catalysts and electrochemical catalysts, which enhance the reduction of carbon dioxide. In conjunction, we are conducting research on the process of producing e-fuel linked with amines, which are primarily used as CO2 capturing agents.
