The Korea Research Institute of Standards and Science (KRISS) has unveiled real-time monitoring equipment to uphold the quality of hydrogen fuel distributed to vehicles, especially through refueling stations. The innovative equipment aims to avert accidents in hydrogen vehicles caused by impurities present in the fuel. Hydrogen fuel, due to its complex production and high-pressure storage, is susceptible to contamination, increasing the risk of explosions and damaging the vehicle's catalyst and performance. KRISS's equipment can monitor and identify impurities promptly, ensuring the fuel's quality. By enabling continuous monitoring and immediate action upon detecting excessive impurity levels, the system enhances the safety of hydrogen vehicles and alleviates user concerns. Dr. Lee Jeongsoon from KRISS highlighted the equipment's ability to measure eight regulated impurities accurately, signaling warnings if any impurity surpasses the defined threshold. This advancement is crucial for improving the safety and reliability of hydrogen vehicles and bolstering confidence in domestically produced hydrogen fuel. The ongoing demonstration of the equipment at a hydrogen bus refueling station in Chungju City signifies a step towards wider adoption and potential technology transfer to local companies, showcasing South Korea's commitment to hydrogen infrastructure advancement.
