Proton exchange membranes, the heart of hydrogen for heavy-duty TECH FOCUS: performance often degrades. Consider these attributes which make PEM technology well-suited for heavy-duty and off-highway applications, where long operating ranges and fast refueling are essential for profitable operation: * Fast startup and less warm-up time. * Low-temperature operation. * Low weight and volume. * Low-level wear on system components. * Superior mechanical and chemical durability. HYDROGEN AND ALTERNATIVE FUELS Lastly, innovators are finding ways to manufacture PEMs responsibly, with an eye toward recyclability and sustainability, thus maximizing resource efficiency. Moreover, collaborations with OEMs and key players throughout the value chain are making this technology more widely accessible to the truck and off-highway industry. As a sustainable, cost-efficient option that exceeds the energy efficiency of combustion engines while eliminating greenhouse gas emissions, PEM technology is quickly transitioning from the " wave of the future " to the way the truck and off-highway industry will be meeting future regulations and making a significant, critical impact on the planet. n Your connection to the mobility community.
