1. Waste-to-hydrogen (W2H)

Organic wastes such as food waste, sewage sludge, and livestock manure generate large quantities of methane, which causes global warming issues. Waste-to-hydrogen not only prevents global warming by utilizing such methane, but also creates new industrial value through hydrogen as an eco-friendly energy.

The waste-to-hydrogen takes organic waste and break it down with microorganisms in a process called anaerobic digestion. This process enables the transformation from waste to biogas. And then biogas is upgraded to biomethane, while removing CO2 and impurities, and biomethane, which is then reformed and reborn as hydrogen.

Waste-to-hydrogen is an advanced technology that has been proven and is already in action in Chungju City, Korea. Hyundai E&C and Hyundai Rotem are participating in a demonstration project for biogas hydrogen production and utilization. It is the world's first facility to produce 500 kg of hydrogen per day using 60 tons of food waste and to operate hydrogen cars in an integrated commercial manner.

The greatest advantage of waste-to-hydrogen is the ability to establish mini hydrogen production hubs at the regional level. Achieving hydrogen resource independence becomes feasible by reducing the cost of the hydrogen transportation and storage process. With these advantages in mind, Hyundai plans to develop specialized resource circulation package projects tailored to different regions and countries.

Additionally, this company is collaborating with hydrogen-dedicated institutions as well as the academic sector to develop new technologies such as liquefied hydrogen storage and carbon dioxide capture, thereby taking a leading role in establishing the hydrogen value chain.

2. Plastic-to-hydrogen (P2H)

Non-recycled plastic waste, whether incinerated or disposed of in landfills, results in environmental pollution in the air, soil, and oceans. As of 2019, the plastic recycling rate accounted for only 9%, and the total amount of plastic waste is expected to increase to 1.23 billion tons by 2060.

Plastics that cannot be recycled and end up being incinerated or deposited in landfills - such as contaminated plastic, composite material waste like toys, and vinyl - can be utilized as materials to produce hydrogen, contributing to the solution of waste issues.

The collected plastic waste goes through the stages to be reborn as hydrogen energy. First, in the “preprocessing” stage, impurities like metal, sand, paper are removed, producing plastic waste raw material. Second, with Hyundai Engineering's self-developed “melting” process, the preprocessed plastic waste is heated and stirred to be melted into a viscous liquid state. This process further removes fine impurities. In the gasification process, plastic waste is melted into liquid and introduced into the gasifier alongside oxygen and steam to produce  a synthesis gas consisting of CO and H2 using Shell's technology. Lastly, in the synthesis gas refining process, additional H2 is produced through the conversion process of CO, impurities contained in the synthesis gas are removed, and CO2 is separated. This results in the production of high-purity hydrogen from plastic waste, completing the transformation into circular energy.

By utilizing 130,000 tons of plastic waste as a raw material, 24,000 tons of hydrogen can be processed in an environmentally friendly manner per year. the hydrogen from plastic-to-hydrogen can be utilized in various fields such as marine fuel methanoal and hydrogen fuel for FCEV.
