In 2023, the climate crisis and energy prices prompted advanced nations to rapidly invest in low-carbon transportation. Fuel cell electric vehicles, especially suitable for commercial heavy-duty use, are gaining traction. South Korea's government and Hyundai Motor are actively promoting policies and products for a broader shift to a low-carbon lifestyle through hydrogen energy. The EU has revised legislation to address carbon emissions from heavy-duty commercial vehicles, and Japan has adjusted policies for Fuel cell electric commercial vehicles with practical goals. These efforts are driving the rapid development of the Fuel cell electric vehicle industry, integrating it into our lives more quickly.
