Cover Story: To lessen the environmental and health impacts of agriculture, innovative powertrains are needed, especially for diesel tractors that emit significant pollution. Fuel-cell systems are a promising alternative due to their low emissions, quick refueling, and efficiency. A comprehensive life cycle assessment is essential to evaluate their sustainability. This article compares the life cycle impacts of diesel and fuel-cell hybrid tractors. This study uses LCA methodology and Ecoinvent 3.0 data, analyzing 10 impact categories. Fuel-cell tractors significantly reduce some impacts, decreasing human toxicity by over 92%, but they only reduce fossil fuel scarcity by 4.55% due to gray hydrogen use. Overall, the climate change impact is reduced by over 34%. Using green hydrogen from solar energy further reduces the impacts of climate change and fossil fuel depletion but worsens other impacts.
