RITE is addressing research and development of new technologies for reducing greenhouse gas emissions
in collaboration with industry, government and academic institutions around the world.

We are working on developing technology toefficiently capture CO₂ from various sources such as
power plant exhaust gases, industrial exhaust gases,
and the atmosphere. In addition, we are promoting
the development of carbon recycling
technology that utilizes CO₂ as acarbon resource.

Development of
CO₂ Storage Technologies
We are developing CO₂ geological storage technology.
Toward the deployment of CCS technology,the CO₂
Storage Research Group conducts research on safe
and stable CO₂ geological storage in deep saline
aquifers for a long term and works closelywith international organizations.

are developing standard evaluation methods for various CO2 separation materials, while keeping
pace with the international trends in this field. In addition, we will establish a real gas test center in
RITE, and support the development of CO2 separation materials by domestic companies, research
institutes, etc.

We are formulating roadmaps for the industrialization of innovative energy and environment

We are also setting up and collaborating on research with manufacturing and user companies.

Under the Paris Agreement, as each country voluntarily submits its
reduction target, an international review system is important to increase
effectiveness. In this regard, we develop evaluation measures of the
Nationally Determined Contributions (NDC) which were submitted to theUnited Nations Framework Convention on Climate Change (UNFCCC)
secretariat, and make an assessment by employing multiple indicators
enabling to measure the level of efforts.

We are developing novel solid sorbents (porous sorbents modified with amines that are used inchemical solvents). The optimal amines and porous supports are chosen depending on the CO2
concentration. We are working on effective CO2 separation from coal-fired power plants (CO2concentration: around 13%), natural gas power plants (CO 2 concentration: around 4%), theatmosphere (CO2 concentration: around 0.04%), etc.

Impurity or byproduct

It is desirable to monitor not only the deformations of reservoir and cap rock but
those of all formations from reservoir to the surface. RITE has been developing afiber-optics sensing technique to measure deformations (strains) of formations allalong a depth direction. Installing our fiber optic system along a deep water
pumping well (300m deep), we have successfully measured deformations of theformations induced by water pumping. We are now trying to improve the installation method.

Also, we make a comprehensive evaluation including synergies
and trade-offs between global warming mitigation and sustainable development, and examines more effective measures.

CCUS has received increasing attention as an important option to mitigate global warming, and is expected tocontribute to approximately 20% of the reduction to be required to achieve carbon neutrality by 2050.
