Core Viewpoint - Hydrogen energy is being transformed from a concept into a practical application in daily life, driven by Pengfei Group's innovative approach to converting industrial waste into clean energy [1][2]. Group 1: Transition to Hydrogen Energy - In 2019, Pengfei Group faced significant challenges in transitioning from traditional coal coking to hydrogen energy, including a lack of technology, market, funding, and talent [2]. - The company has developed a complete hydrogen energy industrial chain, achieving over 99.999% purity in hydrogen extracted from coke oven gas [2][3]. Group 2: Environmental Impact - The transformation of coke oven gas into hydrogen has eliminated carbon dioxide emissions, marking a significant shift from high carbon to zero carbon [3][4]. - The use of hydrogen energy in transportation is exemplified by the operation of hydrogen fuel cell heavy trucks and buses, which contribute to a zero-carbon lifestyle [4]. Group 3: Market Potential and Applications - Hydrogen energy applications extend beyond transportation to agriculture and household use, with products like hydrogen-rich vegetables and tofu being developed [5]. - The hydrogen-powered drone developed by Pengfei Group demonstrates versatility in various sectors, including disaster response and agricultural monitoring, with a maximum operational radius of 30 kilometers [6].
