To support the transition to ZE-MHDVS in India, CALSTART recently commissioned pManifold to do an industry assessment and roadmap for zero-emission medium- and heavy-duty trucks (ZE-MHDTs) in India. This wide-ranging study included a review of the existing truck manufacturing landscape, truck fleet landscape, a techno-commercial feasibility assessment of ZE-MHDTs based on real-world duty cycles, an assessment of industry readiness for ZE-MHDT manufacturing, and a roadmap for ZE-MHDT deployment.
