Green shipping corridors arebecoming a critical tool for accelerating the adoption of zero- and near-zero emission fuels to achieve this goal. India is positioned well to be a leader in this transition. Buoyed by abundant renewable energy resources and resulting lowgreen hydrogen production costs, India can spearhead the market development for green hydrogen-derivative fuels.
