However, despite its advantages, there are some challenges associated with CNG. One of the primary obstacles is the availability and accessibility of refueling stations. In many regions, CNG infrastructure is still underdeveloped, leading to concerns about the feasibility of long-distance travel. Additionally, while the production of CNG is cleaner than other fossil fuels, it still involves extraction processes that can have environmental impacts, such as methane leakage during gas extraction and transportation. As such, it is essential to continue refining extraction methods and improving the sustainability of the entire supply chain.
