CMF Drive

Upcycling of old diesel buses into clean, efficient buses powered 100% by renewables

Identification

Climate change is leading to various problems for society and nature. Air pollution from motorized mobility in cities harms the health of the inhabitants and jobs in the automotive industry are shifting to Asia. These are some of the reasons which led to the development of the Clean Vehicle Directive (DIRECTIVE (EU) 2019/1161). According to this directive, municipalities are forced to reach procurement targets of clean and energy-efficient vehicles. This is a huge challenge for municipalities, as existing alternatives to diesel buses are not always suitable or are extremely expensive. In order to meet the needs of these municipalities, CMF recovers their old buses and remove all diesel components like tanks, engine etc. and install the patented CMF drive. It consists of an electric drivetrain with an onboard charger and enables 3-fold energy savings: Through the recovery of braking energy, usage of engine waste heat and constant optimal load at the on-board charger. Thanks to upcycling, CMF avoids the production of unnecessary material. The CMF drive runs on liquid natural gas (LNG), Bio-LNG or synthetic natural gas. Suitable fuel stations already exist all over Europe and as soon as green hydrogen is available in sufficient amounts the CMF will easily be adapted to it.

Implementation Stories

CMF Drive by CM Fluids
Implemented by Munich Airport in Munich (Germany) in 2021

Munich airport wanted to become CO2 neutral and truly sustainable in the most economical way by reducing 60% and compensating 40% of its CO2 emissions. One system was installed in an upcycled bus as a first prototype demonstration in an operational environment – partly funded by development partners, investors and subsidies. The bus was planned to replace a conventional diesel bus to cover various routes of the airport and the system was leased to the client for the test.

Result

800 t of co2 per vehicle, +12 years bus lifetime expansion & -95% particulate matter emissions
