75. CCS Demonstration Project in Tomakomai

For CCS demo-plant, Hokkaido refinery of Idemitsu

supplies CO2 which is off-gas from the hydrogen generator.

B. Development of New CCUS Technologｙ”Mineralization"


1. Mineralization(carbonate)9

No need of hydrogen nor additional

energy

Not toxic, stable ⇒storage easily

Huge amount of Ca and Mg are

existing in the earth’s crust and sea

water.

Limestone(CaCO3) has a large

market, such as construction

material.

High Gibbs energy

Low

CO2

Ethylene C2H4

Methane CH4

Calcium Carbonate

CaCO3 -1207 kJ/mol

-394kJ/mol

-74.9kJ/mol

+28.1kJ/mol

CaO+CO2→CaCO3(solid）

MgO+CO2→MgCO3(solid）A method of CO2 capture by basic

compound of calcium and/or magnesium.

3. The first step of Carbon Recycle11

Mineralization is regarded as a technology capable of

achieving in the 1st phase in the Technical Road Map

by METI in 2019 .

cement will grow largely, and many organizations have

been challenging it.

5. Development of CO2 mineralization

Idemitsu, Ube Industries, and JGC Corporation established

CCSU※ research consortium in order to develop a new

technology, CO2 mineralization using industrial waste materials.

The new CO2 recycling system by Ca has a huge potential of

preventing new CO2 emission from natural limestone.

Estimated the amount of CO2 recycling may be 2.3b t/y in global.

Japan Coal Energy Center

・GreenOre Tech

・Columbia University

・Wyoming Infrastructure Authority

MOUTest carbon utilization

and recycling

Support

Assess the applicability of

the technology to Japan

Japan USA

JCOAL and GreenOre Clean Tech and others of USA agreed to test a

new CCU and recycling. Idemitsu will support to this project.

Dry Fork Power


8. Conclusion16

But, there are a lot of hurdles to develop practical systems.

・Development of high-efficiency process and prevention of

generation of a large amount of new CO2 and waste.

・Collaborations among different industries and

international organizations

・Restructuring of the social system,

such as regulations of industrial waste, construction

material and so on.

⇒Need of support by the Government etc.

”Mineralization" has a huge potential for CO2 reduction.

・Spontaneous reaction (energetically advantage)

・Huge market of product

＝ Larger potential of fixing CO2 than other CCUs
