California's Environmental Protection Agency has granted approval for the state to enforce a rule that will prohibit the sale of new gasoline-powered vehicles by 2035. Governor Gavin Newsom has praised this decision, emphasizing the benefits it will bring by reducing harmful air pollution through the adoption of cleaner electric and hybrid vehicles. This move is part of California's commitment to promoting clean energy and sustainability. The recent unveiling of the hydrogen-powered passenger train, Zemu, in San Bernardino marks a significant milestone in the state's efforts to achieve carbon neutrality by 2045. The $20 million train uses a hybrid hydrogen fuel cell and battery system to power a lightweight vehicle capable of carrying passengers along the Arrow Corridor. Zemu is expected to not only improve air quality in the area but also provide a quieter and environmentally friendly mode of transportation. By combining hydrogen and oxygen molecules, hydrogen fuel cells generate electricity and water vapor, making Zemu a zero-emission technology. The project has been in development for years, with the aim of alleviating air pollution and reducing road congestion in the region. Officials believe that Zemu will set a new standard for sustainable transportation in North America, meeting federal requirements and promoting innovation in the public transport sector. The positive sentiment towards hydrogen technology in California highlights a shift towards cleaner and more efficient modes of transportation.
