Toyota to build prototype city of the future, powered by hydrogen fuel cells

Green Car Congress

Called the Woven City , it will be a fully connected ecosystem powered by hydrogen fuel cells. The rooftops will be covered in photo-voltaic panels to generate solar power in addition to power generated by hydrogen fuel cells. The plan is for 2000 people to start, adding more as the project evolves.

Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

The study was published in the journal Atmospheric Environment. In addition to CO 2 , air traffic causes condensation trails and nitrogen oxide (NO x ) emissions from the combustion of the airplane’s fuel. Both radiative forcing (RF) and effective radiative forcing (ERF) terms and their sums are calculated for the years 2000–2018.

U Toronto study measures GDI emissions in urban near-road environment

Green Car Congress

A study of emissions from gasoline direct injection (GDI) vehicles in an urban near-road environment in Toronto over a wide range of weather conditions (February 2014 to January 2015) found that—other than for NO x and CO—the GDI engines had elevated emissions compared to the Toronto fleet.

Rolls-Royce Power Systems road map for climate-neutrality; 35% cut by 2030 from 2019; key role of mtu engines

Green Car Congress

A key element in achieving these goals is the certification of the most important mtu engine products, which will run on sustainable fuels from as early as 2023 and then be successively brought into use. Or it relates to fuels such as hydrogen, that would not at all emit CO 2 at the exhaust pipe. but also second-generation biofuels).
