Cambridge study of near-term alternative London bus technologies finds lean-burn CNG most costly with greater climate impact than diesel

Green Car Congress

Annual GHG emissions relative to BASE Scenario (BASE Scenario = 949 kt CO 2 e on a 100-year GWP basis) for differing London bus fleet technology options. Although hybrid buses provide net GHG reductions and air quality improvements, associated costs are higher and more uncertain than emission retrofits. Credit: ACS, Chong et al.

HyBoost Project Aiming for 30-40% CO2 Reduction Without Performance Compromise

Green Car Congress

The HyBoost project ( earlier post ), a two-year collaborative research program led by Ricardo in partnership with Controlled Power Technologies, the European Advanced Lead Acid Battery Consortium, Ford, Imperial College London, and Valeo, aims to demonstrate a very cost-effective, ultra-efficient gasoline engine in a C-segment passenger car.

New ABB Azipod D for electric marine propulsion requires 25% less installed power, boosts flexibility

Green Car Congress

This is partly due to the fact that the new hybrid (air and water) cooling helps reduce the thruster’s weight and directs more power toward propulsion of the ship, not cooling requirements. Fuel consumption—and thus exhaust emissions—are reduced due to improved hydrodynamic efficiency and the power plant concept.

London launches $111M program to upgrade around 5000 older buses to Euro VI emissions standard

Green Car Congress

The Mayor of London, Sadiq Khan, launched a £86.1-million million (US$111 million) program to retrofit around 5,000 older buses with a new exhaust system that will upgrade the vehicles to Euro VI emissions standards. From next year, all new double-deck buses will be hybrid, electric or hydrogen.

ATI FlyZero project finds green liquid hydrogen most viable zero-carbon emission fuel for aircraft

Green Car Congress

FlyZero compared zero-carbon emission energy sources such as batteries, hydrogen and ammonia; the team concluded that green liquid hydrogen is the most viable, able to power large aircraft utilizing fuel cell, gas turbine and hybrid systems. It is critical to achieve these dates to hit the net zero 2050 goal.
