Fuel-cell electric vehicles (FCEVs) are gaining traction as a sustainable alternative to traditional vehicles due to their efficiency and lack of greenhouse emissions. Major automakers like Toyota, Honda, and Hyundai are at the forefront of this movement, focusing on applications in heavy-duty trucks, buses, industrial settings, and stationary power units. Progress in the hydrogen economy is being accelerated by clean air initiatives, with programs like California's Hydrogen Hub aiming to reduce emissions significantly. Major players like Ballard, General Motors, Toyota, and Hyundai are actively involved in supplying fuel cells and advancing technology. Challenges in establishing a hydrogen infrastructure include developing a network of fueling stations and addressing storage complexities. Despite these hurdles, advancements like cryopumping technology are showing promise in reducing costs and improving efficiency. In the United States and Europe, there are plans to increase the number of hydrogen fueling stations significantly by 2030. The key is to create a supportive infrastructure that can meet the demands of FCEVs and promote the adoption of hydrogen as a viable and sustainable energy source.
