Promoting green innovation

To promote green innovation, AIST is developing technologies for increased use of alternative energy technologies, such as renewable energy sources that reduce greenhouse gas emissions (energy creation), high-density storage of energy (energy storage), highly efficient conversion and use of energy (energy saving), effective utilization of energy resources, and evaluation and reduction of environmental risks.

Development of a Catalyst to Synthesize Ammonia at Low Temperatures and Pressures

AIST developed a catalyst for ammonia synthesis that can respond to the fluctuations in output power of renewable energy sources. The catalyst resolves the issue of the decline in catalytic performance at high pressures and maintains high activity at pressures below 10 MPa. AIST has started ammonia synthesis demonstration tests using the developed catalyst.

12% Efficiency Achieved with a Cascade-type Thermoelectric Module

AIST formed nanostructures by adding Ge to PbTe. The nanostructures allow electric current to flow through and result in low heat conduction. A cascade-type thermoelectric module was developed by stacking the nanostructured PbTe module on the hot side of a Bi2Te3 thermoelectric module, and a conversion efficiency of 12% was achieved.


Thermoelectric figure of merit in material and conversion efficiency in module were dramatically enhanced through nanostructuring.

Open Innovation Laboratory

Since FY 2016, as a part of the “Open Innovation Arena concept” promoted by the Ministry of Economy, Trade and Industry (METI), AIST has created the concept of “open innovation laboratories” (OILs), collaborative research bases located on university campuses, and has been engaged in their provision. We are planning to establish more than ten OILs by FY 2020.

AIST will merge the basic research carried out at universities, etc. with AISTʼs goal-oriented basic research and applied technology development, and will promote bridging research and evelopment and industry by the establishment of OILs.

Cooperative Research Laboratories

In order to conduct research and development more closely related to strategies of companies, we have established collaborative research laboratories, bearing partner company names.

Partner companies provide their researchers and funding, and AIST provides research resources, such as its researchers, research facilities, and intellectual property. The loaned researchers of companies and AIST researchers jointly conduct research and development.

By setting up cooperative research laboratories, we will accelerate the commercialization of our goal-oriented basic research and application research with partner companies.
