Green hydrogen uses electrolysis to split water and release only hydrogen and oxygen. Hydrogen produced by steam reforming is termed grey hydrogen, which is the most common form and is generated from natural gas, or methane. Blue hydrogen is produced using carbon capture and storage (CCS) technology which is used to capture and store CO2 generated during the hydrogen production process.
Doosan Fuel Cell will work with the state-run Korea Institute of Energy Research (KIER) to develop carbon capture and utilization (CCU) technology linking fuel cells. CCU technology is used to capture carbon generated in the hydrogen production process. It is a key technology to produce hydrogen and reduce CO2 emissions.
They will carry out the demonstration of blue hydrogen fuel cells using CCU technology, together with Korean Southern Power (KSPO), a public power company, and replace hydrogen fuel cells with blue hydrogen fuel cells.
Doosan Fuel Cell will develop ammonia fuel cells that use ammonia, a stable hydrogen carrier. Samsung C&T, a trade, investment and construction arm of Samsung Group, will introduce ammonia from abroad. KOSPO will provide a demonstration site. Hydrogen can be produced by burning and reforming ammonia in a micro-reforming system. Ammonia is seen as an ideal resource to establish an eco-friendly hydrogen fuel cell-based infrastructure.
"Through this MOU, we will actively respond to the government's clean hydrogen policy and accelerate the transition to clean hydrogen fuel cells by securing technological competitiveness with a great gap," Doosan Fuel Cell CEO Chung Hyung-rak said in a statement on June 3.
Hydrogen fuel cells use hydrogen as fuel to produce electricity. Small-sized cells are installed in eco-friendly vehicles such as full-size sport utility vehicles while larger cell systems are used in hydrogen power generators. South Korea is investing heavily to utilize hydrogen fuel cells as a new power source. In September 2021, Doosan Fuel Cell secured its first contract to export hydrogen fuel cells for power generation.
