BMW, the German carmaker, is set to launch a hydrogen car in 2028, based on the successful trials of their iX5 Hydrogen prototypes. Testing covered various countries globally, with a focus on developing Hydrogen Fuel Cell Electric Vehicles. BMW's partnership with Toyota aims to bring this technology to the market, highlighting the benefits of using hydrogen as a fuel source. Despite challenges like lower efficiency compared to battery electric vehicles and infrastructure limitations, hydrogen offers advantages such as quick refuelling times and the ability to transport green energy. In regions like Europe, efforts are being made to establish hydrogen refuelling stations, while Australia lags in such initiatives. The debate around hydrogen's production methods, specifically the need for green hydrogen from renewable sources, continues. Despite criticisms from some quarters, the move towards green hydrogen signals a positive step towards a more sustainable fuel source for the automotive industry.
