Core Insights - A new catalytic technology has been developed that enables the direct separation and storage of industrial crude hydrogen, addressing long-standing challenges in the industry [1][2] - The global hydrogen production exceeds 95 million tons annually, with China contributing over 33 million tons, primarily from fossil fuel reforming processes [1] - Existing separation and purification technologies are complex and costly, leading to significant resource waste in utilizing crude hydrogen for high-end applications like fuel cell vehicles [1] Group 1 - The new catalyst exhibits strong "poison resistance," maintaining efficiency even in harsh conditions with COx concentrations exceeding 50% and temperatures up to 170 degrees Celsius [2] - The process significantly simplifies the traditional methods, reducing energy consumption and equipment investment by integrating separation and storage into a single step [2] - The technology produces high-purity hydrogen suitable for fuel cells, while the COx-rich byproduct also holds economic and application value [2]
