Toyota is making remarkable strides in the development of liquid hydrogen engines, devoting significant resources to research and advancements in the field. While still supporting electric vehicles, the company is shifting focus towards hydrogen fuel projects due to their belief in hydrogen as the future of the automobile industry. The Toyota Mirai, a second-generation hydrogen fuel cell vehicle, is available for sale in multiple countries, offering a green alternative powered by hydrogen gas and oxygen that only emits water. Despite its eco-friendly features, customers have faced challenges with refueling the Mirai, leading to lawsuits against Toyota. However, Toyota remains committed to improving hydrogen fuel technology, with recent breakthroughs including re-using 'boil-off' hydrogen and developing hydrogen capsules for vehicles. The company is also addressing the lack of hydrogen filling stations and promoting environmentally friendly options in the face of concerns about the manufacturing processes and supply chain of electric vehicles. Toyota's innovative approach to liquid hydrogen engines marks a significant advancement in the automobile industry, providing a promising alternative to traditional electric vehicles.
