Hyundai Oilbank turns carbon emissions into cement and concrete

0
Hyundai Oilbank captures carbon emissions and turns them into raw materials used for cement and concrete on construction sites, as part of its carbon neutral commitments.

According to Hyundai Oilbank on Friday, it will collect by-products generated by its petrochemical facilities such as desulphurized gypsum and carbon dioxide and process these wastes into construction materials such as plaster and calcium carbonate.

Next year, Hyundai Oilbank will inaugurate a production facility to produce up to 100,000 metric tons of carbon-processed products per year. The company aims to gradually increase the capacity to 600,000 tonnes.

When complete, the facility is expected to capture 120,000 tonnes of carbon emissions per year, given that one tonne of carbon-converted products is equivalent to capturing and using 0.2 tonnes of carbon dioxide. This means the facility can capture the same amount of carbon emissions as 10 million pines.

The carbon processed products will be supplied to construction sites as raw materials for cement, concrete and lightweight blocks. Carbon-processed products are cheaper than sourcing new materials from mines, according to Hyundai Oilbank.

Hyundai Oilbank’s CCU technology is expected to support Hyundai Oilbank’s plan to produce 100,000 tons of blue hydrogen by 2025.

Hydrogen, although colorless, is given color labels based on its raw material and method of production. Blue Hydrogen extracts hydrogen from natural gas but captures the carbon emitted in the process.

In addition, CCU technology should find immediate application in Hyundai Oilbank’s petrochemical facilities. Hyundai Oilbank produces 200,000 tonnes of hydrogen annually from naphtha, natural gas and liquefied petroleum gas and uses it in a process called desulfurization. The process leads to 360,000 tonnes of carbon dioxide emissions.

Hyundai Oilbank is currently putting in place the necessary infrastructure to resolve the issue. Starting next year, 200,000 tonnes of carbon dioxide emitted from hydrogen production at the company’s Daesan plant will be supplied to close partners who make dry ice and specialty gases used to make semiconductors.

The remaining 160,000 tonnes will be supplied to Hyundai Oilbank’s current partner, Sundo Chemical.
