Gianni López is a professional with extensive experience in environmental management since the beginning of 1990. He was Director of the National Commission of the Environment with participation in the atmospheric decontamination work in the city of Santiago – Chile, has carried out very relevant projects to promote the environmental progress of Chile. He developed the “Decontamination Bonus Project” for the application of marketable emission permit systems. He currently directs research on transportation technology and the implementation of applied cases at Mario Molina Center Chile.

  • June 11: E-buses for the masses

    Sustainable bus system project

    Latin America’s reliance on urban buses for public transportation makes it one of the leading markets for this vehicle mode globally. Some of the biggest cities in the region are facing the renewal of their bus fleets, both due to outdated performance and age. It is essential that, at this juncture, energy-efficient, low-polluting, and soot-free buses be introduced into public transport systems. In this context, advanced technologies require an appropriate characterization of the advantages of clean and energy-efficient buses in terms of emissions, operational costs, and fuel economy. These characteristics vary, however, depending on local operating conditions, emission regulations, fuel quality, and type of service the buses provide. Verified performance data is needed, as well as test and assessment methodologies that reflect local needs and conditions.
    The methodology developed was divided into the following three components: First, the design of a driving cycle and test procedures which represent the operating conditions of buses in the Santiago public transport system. Secondly, the development of a laboratory-testing program for urban buses with advanced technologies, where eight buses were tested using the Santiago urban bus cycle in the VTT's lab in Finland and in the Ministry of Transport and Telecommunication’s laboratory (3CV) in Chile. In addition, the Autonomie vehicle modeling software was used to simulate the behavior of different bus technologies tested in the labs. Finally, the preparation of recommendations both for the use of the Santiago urban bus cycle, and for test procedures which the Ministry of Transport and Telecommunications of Chile carries out during the evaluation and selection of bus technologies that will enter the Santiago public transportation system's fleet, so that these contribute towards energy efficiency and reduce the system's emissions. The Sustainable Bus System Project developed the first case of procedures, protocols and a test program for new buses that was officially adopted in August 2018 by the Chilean Government for mandatory testing of every new bus model seeking to operate in Santiago (Resolution 2.243, available at http://bcn.cl/26gbi). Santiago is the first city in the region to introduce Euro VI (500 diesel) and battery electric buses (100+) during 2018, and Ministry of Transport and Telecommunication is using this work to support this process. During 2019 it will also be used to determine the performance and energy consumption during the tendering process which will replace the current fleet of urban buses (Euro III + DPF) with approximately 500 electric and 2,700 Euro VI/EPA2010 buses. The project Sustainable Bus System was developed under IEA´s Advanced motor fuels Technical Cooperation Program, and its aim was to develop a methodology for setting requirements for clean and efficient buses for use in tendering process for transit fleets in developing regions. A driving cycle representative of bus operation in Santiago City was developed and different technologies of buses were tested in Finland and Chile, including diesel, CNG and battery electric. Finally, recommendation for test procedures and use of Santiago Urban Bus Cycle were prepared. The results of this report served as the basis for the official adoption of the Santiago Drive Cycle as the basis for bus procurements in Santiago de Chile and it will be used on tender process for the energy consumption determination and performance, including the first Euro VI diesel and battery electric buses in Latin America.
