The quest for a sustainable alternative to power vehicles is seeing a resurgence in interest towards hydrogen. While lithium-ion batteries were once hailed as the future, they are now being overshadowed by the potential of synthetic diesel fuel and hydrogen combustion. Engine manufacturers, including AGCO, are designing engines that can run on multiple fuels to hedge their bets. JCB, led by Anthony Bamford, is actively promoting hydrogen as the solution for a carbon-free off road fleet. However, legislative challenges in the UK have constrained the testing of hydrogen-powered machines on roads, despite JCB's efforts to showcase their viability. While JCB has been granted special permission to test their hydrogen-powered diggers, the broader acceptance of hydrogen in off road vehicles still faces hurdles. The need for a distribution infrastructure for hydrogen supply, along with challenges in hydrogen production, further complicates the transition. Despite these obstacles, JCB persists in advocating for hydrogen as a replacement for diesel fuel, supported by prominent figures like Boris Johnson. The push for hydrogen as a sustainable fuel source is commendable, but the realization of a widespread shift to hydrogen-powered vehicles and the necessary infrastructure may be a few years away.
