“…Totally 24 tenders were made by local governments for the purchase of electric buses, projects, and infrastructure requirements in Turkey in 2020, 8 of these tenders were canceled due to various reasons. 1,10 On the basis of the first quarter of 2020 for Turkey, according to tender contracts, it is expected to be passed to the electric buses in public transportation system in totally 118 pieces new electric buses (in different sizes) but 86 electric buses could be delivered to the administrations by the relevant supply companies for various reasons. Currently, there is no recorded data about how many of them are actively used.…”

“…Currently, there is no recorded data about how many of them are actively used. 1,11 On the other hand, electric buses are not yet included in the current bus fleets of the most important public transportation authorities in Turkey such as Istanbul and Adana. In addition, there are no regulations or more importantly, incentives and/or support mechanisms, except for the recommendation regarding the use of electric buses in the public transportation system in Turkey (Item 338.5 of the 11th Development Plan of the Republic of Turkey).…”

“…Although many city-based targets have been set for electric solutions in rubber-wheeled public transportation systems in the world, only 100% of the electric bus solution in public transportation was achieved in Shenzhen (China). 1,2 According to the data of 2019, electric car sales increased by 2.1 million; have exceeded 2018. Also it globally reached 7.2 million.…”

“…4 Considering the current sectoral reports, literature and market researches; when accessible costs and sufficient technological maturity are reached in electric vehicles; public transport with the rubber wheel systems are considered to be the fastest and easiest to adapt to area for the electric buses. 1,7 At the present time, the electric bus concept is included in the portfolio of all bus manufacturers in the market. Within the framework of delegations created on zero emission, there is a wide-ranging trend toward electric buses, especially for public transportation companies.…”

The trend toward electric buses worldwide is increasing day by day. Along with it, sectoral infrastructure elements are developing rapidly. Electric buses offer advantages in terms of operating costs and environmental emission values. Despite this, the most important disadvantage is that the purchasing costs have not yet reached the expected level compared to other internal combustion engine buses. Many country and especially city-based targets have been determined for electric solutions in rubber-tyred public transportation systems in the world. Only in Shenzhen city of China, 100% transition to electric bus solution has been achieved in public transportation. In this study, a different perspective has been put forward for the acceleration of the transition to the use of electric buses and the increase in the prevalence of public transportation enterprises. The concept of retrofit. This is conversions of the conventional powered (diesel and CNG) buses into electric buses, which are currently used. For the concept in paper, the actual project costs for one of the world’s most important public transportation companies have been revealed. According to the analysis results obtained, for Payback Period (PB) method are based on a fleet of 100 vehicles in total, the return time of the investment required for the results based on this approach which retrofit from CNG to Electric, is calculated as 8.74 years. For the Payback Period (PB) approach, it has been concluded that for the 5 years, which is envisaged to be taken as a reference, retrofit concept (from CNG to Electric) should be based on 100000 € per vehicle based on the current operating conditions. This retrofit approach based on the concept of sustainable public transportation is expected to become widespread with the results obtained.

As cities grow and become more populous, the demand for public transportation increases due to a need for authorities to expand their transportation capacity. However, the increased use of vehicles can cause environmental impacts such as air pollution, greenhouse gas emissions, and noise. To address these issues, governments and other stakeholders seek alternative transportation systems or technologies. This paper intends to assess the financial viability of using fuel cell hybrid-electric buses as an alternative transportation system for the Istanbul Metrobus System. The analysis is based on the Payback Period Method, which evaluates the costs and benefits of a project over its lifetime. The study compares the total operating costs of using fuel cell hybrid-electric buses to diesel and battery-electric buses. The study determined that fuel cell hybrid-electric buses can lead to a reduction in total operating costs of 81.1% compared to diesel buses and 56.3% compared to battery-electric buses. This analysis suggests that fuel cell hybrid-electric buses offer added value after approximately 9 years. The outcome of this study is significant as it can help stakeholders take informed decisions about the financial viability of alternative transportation systems. Furthermore, the financial model or approach used in this study can be useful for understanding how public transportation systems can be funded in the future.
