Hyundai Oilbank sets sights on establishing blue hydrogen plant
Hyundai Oilbank is making strides in carbon emission mitigation, with its carbon capture and utilization (CCU) projects.
The oil refiner is recycling carbon dioxide to roll out diverse products, one of them being carbonated building materials. Hyundai Oilbank produces carbonated building materials such as anhydrous gypsum and calcium carbonate out of carbon dioxide and desulfurized gypsum, by-products of oil refinement.
Hyundai Oilbank plans to construct a factory to produce 100,000 tons of carbonated products a year, and aims to expand the production to 600,000 tons in the future, the company said.
As a result, Hyundai Oilbank will be reusing 500,000 tons of desulfurized gypsum annually, while offsetting 120,000 tons of carbon emissions a year, as 0.2 tons of carbon dioxide is used per every ton of carbonated products.
Relatively eco-friendly and low-cost, the carbonated products will be used as alternatives for building materials such as cement, concrete and light weight blocks. Carbonated cement and concrete is not only more environmentally friendly, but also more resilient.
Hyundai Oilbank is joining forces with DL E&C for the project. DL E&C will participate in the construction of the CCU plant built in the Hyundai Oilbank’s Daesan Plant in South Chungcheong, and also actively incorporate carbonated products in its construction projects.
The blue hydrogen production system articulated with the CCU process is also noteworthy. Unlike grey hydrogen, which emits carbon dioxide during refinement, blue hydrogen is comparatively eco-friendly because the emitted carbon dioxide is captured and recycled.
Oil refiners use hydrogen in the desulfurization process. Hyundai Oilbank, too, generates 200,000 tons of hydrogen a year and emits 360,000 tons of carbon dioxide as a result.
Hyundai Oilbank is establishing the infrastructure to capture and utilize all of carbon dioxide emitted during hydrogen generation processes in collaboration with other companies. Hydrogen manufacturing processes, therefore, will become a blue hydrogen plant, for the first time in domestic oil refining industry.
