Buses have long been a fundamental mode of transportation worldwide, notably in urban areas. Traditionally, diesel engines powered buses for decades until a recent transformation to electric buses. IDTechEx's report reveals a surge in global electric bus sales, indicating a shift towards sustainable urban transport. The research forecasts a continuous growth rate of 5.3% till 2045, demonstrating a positive trend towards emissions-free transportation. China stands out as a pioneer in adopting electric buses, with significant sales in 2016, influencing other regions to follow suit. Other areas like Europe, the US, and India are progressively integrating electric buses into their transport systems, emphasizing sustainability. The report delves into the evolving technologies behind electric buses, including full battery electric, fuel cell, and hybrid models, showcasing a promising market outlook. Furthermore, it outlines the advancements in electric motors and batteries, identifying central motors versus integrated axles and the varying battery chemistries used across regions. With an anticipated $50 billion market by 2045, the electric bus sector is witnessing a diversification of players, from established OEMs to startups like Ebusco. The analysis also compares the effectiveness of hydrogen fuel cell, hybrid, and battery electric buses, with the latter prevailing due to improved energy density and cost efficiencies. The increasing onboard battery capacity in Europe and America reflects the progress in overcoming the range limitations of electric buses. Overall, the report underscores the growing global shift towards sustainable urban transportation driven by the electric bus revolution.
