CO₂-free turquoise hydrogen production
Hydrogen can be produced using methane pyrolysis without CO₂ emission, the turquoise hydrogen production. In a high-temperature pyrolysis reactor, the methane (CH₄) feed is directly decomposed into solid carbon (C) and hydrogen (2H₂).
HERO Lab. has been being devised a high-temperature reactor and examined the reaction's kinetic characteristics. Also, the overall process, including reactor, heat supply, and purification, has been designed, simulated, and optimized in terms of thermodynamic efficiency, economics, and environmental performance.
SOEC based green hydrogen production
SOEC (solid oxide electrolysis cell) operates at high temperatures over 700 degrees C, using ceramic-based electrolytes, e.g., yttria-stabilized-zirconia. Being compared to other types of electrolysis, such as PEM electrolysis or alkaline electrolysis, SOEC is favorable in electrical energy use since SOEC can be integrated with other thermal facilities, such as incinerators, steel-making plants, cement plants, and high-temperature nuclear reactors.
HERO Lab. has been being studied various integrations of SOEC and other thermal facilities. Process modeling, dynamic simulation, off-design calculation, economic analysis, life cycle assessment has been performed to figure out the most economically and environmentally feasible option.
