MHY BUS - Methane and Hydrogen blend for public city transport bus: technical demonstrative application and strategic policy measures

PROJECT DESCRIPTION

The MHyBus project (Methane and Hydrogen blend for public city transport bus: technical demonstrative application and strategic policy measures) was aimed at reducing the environmental impact of the urban public transport (in terms of CO2 and pollutant emissions into the atmosphere) through the implementation of the first prototype in Italy of a hydro-methane bus (mixture of 15% hydrogen and 85% methane by volume). The vehicle run more than 45.000 km in Ravenna with over 10.000 passengers on-board circulating in the regular public transport service. During the road tests, environmental parameters relating to pollutant emissions and fuel consumption were monitored. These data provided a solid knowledge base for the air quality and climate change policies at regional level.

The project results showed that the hydro-methane has a great potential to reduce the environmental impact of the public transport. Taking advantage from the circulation of the vehicle on the urban roads, MHyBus also intended to raise the awareness of  Emilia-Romagna citizens on climate change and air quality issues.

 

PROJECT PHASES

The main phases of the project were:

  • bench test and bus prototype development;
  • implementation of a special hydro-methane fuelling station as well as of road tests with and without passengers carried out according to a protocol defined together with the Ministry of Infrastructure and Transport. In this phase, the absence of technical problems and the monitoring data of the engine’s performance demonstrated that the use of hydro-methane blend does not limit the vehicle’s standard operation;
  • development of technical guidelines (addressing local transport agencies) for transformation of a public transport vehicle powered by methane into one powered by hydro-methane, as well as of a roadmap for introducing hydro-methane as alternative fuel;
  • set up of a hydro-methane Community,  also operating on the project website, where all the outputs and deliverables are available;
  • dissemination and information activities which involved several organizations, companies, professionals and technical experts in workshops and seminars.

 

PROJECT RESULTS

MHyBus demonstrated that the use of hydro-methane blend increases the sustainability of public transport, thanks to a reduction of the CO2 emissions by 15% and of the fuel consumption by 13%. The project can be considered a pilot initiative as far as it tests new technical aspects and it also defines the type-approval procedures for  a new vehicle to be used in the public transportation.

Therefore the project is a possible solution to fight climate change and to improve air quality at a local scale, with a high potential also on wider scale.

Given the good results of its  experimentation, the vehicle is presented at several sustainable mobility events for demonstration purposes. The project’s success moved over the regional borders, attracting interest at international level, especially in Lithuania and Korea.

Results in figures:

  • 1 bus prototype running on hydro-methane (15% hydrogen and 85% methane by volume). The type-approved vehicle runs regularly in Ravenna;
  • 1 hydro-methane fuelling  station built within the production plants of  the “SOL S.p.A” company in Ravenna;
  • 1 experimental protocol to obtain approval for circulation on public roads agreed with the “Centro Prova Autoveicoli” (Ministry of Infrastructure and Transport);
  • 4 series of tests passed successfully: preliminary tests; tests during experimental operations;  final tests including engine bench test; components testing and final leakage tests;
  • more than 10.000 transported passengers on the regular scheduled service “START Romagna” in Ravenna;
  • 45.898 km run on road  without technical problems potentially caused by the hydro-methane blend;
  • 12.600 kg of produced hydro-methane;
  • 13% less of fuel consumption compared to a natural gas vehicle;
  • 1.800 kg of saved methane;
  • 15% of avoided CO2 emissions compared to a similar vehicle powered by natural gas;
  • 5.980 kg of CO2 emissions avoided in the atmosphere.

MHybus was awarded “Best LIFE Environment project 2014”.
