Abstract:
Greener alternatives for fuelling automobiles, such as hydrogen transport and electric vehicles, have shown
considerable promise in transportation. Many others are sceptical of the growing enthusiasm for these new
technologies, believing that energy storage technologies and management are insufficient for a complete shift.
Such a network of variables and smart grid technologies that can help with the transition may reveal some
systemic hazards linked with financial institutions, company risk and failure, and so on. This study attempts to
characterise spillovers and connections between the indices of green transportation, smart grid, innovative
materials, energy storage, and energy management globally. To do this, we employ a novel strategy developed by
Balcilar et al. (2021) as well as a robustness check using the well-known Diebold and Yilmaz (2012) method. The
study highlights the sub-systemic sector’s connections, giving policymakers insights into instruments to support
financial market sustainability and stability. It would be critical to separate the impact of these indicators, but
given the intrinsic relationship, this would be nearly impossible. The transportation innovation network is not
rigid and established in its interconnection. The role of indicators shifts from transmitting to absorbing shocks
regularly, and policymakers who want to encourage long-term solutions must be aware of this.
