SANY developing hydrogen fuel cell construction vehicles

Green Car Congress

With a high-torque drive motor and an AMT gearbox, the high-power fuel cell stack features an energy conversion rate of more than 50%. At the 2020 United Nations Climate Change conference, Chinese President Xi Jiping proposed that China’s carbon dioxide emissions should peak in 2030 and that carbon neutrality should be achieved by 2060.

Columbia University engineers make breakthrough in understanding electroreduction of CO2 for conversion to electrofuels

Green Car Congress

Recent research in electrocatalytic CO 2 conversion points the way to using CO 2 as a feedstock and renewable electricity as an energy supply for the synthesis of different types of fuel and value-added chemicals such as ethylene, ethanol, and propane. The spectroscopic results were corroborated by quantum chemical modeling.

Report Suggests Biorefineries May Have a Major Role in Mitigating Climate Change, Addressing Energy Security, and Creating Economic Growth

Green Car Congress

Biorefineries may have a major role to play in mitigating the threat of climate change; meeting the “ seemingly boundless demand ” for energy, fuels, chemicals and materials; and creating economic growth, according to a new report released by the World Economic Forum: The Future of Industrial Biorefineries.

Lifecycle study finds fuel switching from diesel to natural gas could produce net climate damage absent reductions in CH4 emissions and improved vehicle efficiency

Green Car Congress

Otherwise, fuel switching can produce net climate damages (more radiative forcing) for decades. since natural gas has relatively low carbon intensity, releasing less carbon dioxide (CO 2 ) per unit of usable energy than other fossil fuels, it is often assumed that switching to natural gas is comparatively beneficial for the climate.

Study: expanding Brazilian sugarcane for ethanol could reduce global CO2 emissions by up to 5.6%

Green Car Congress

Vastly expanding sugarcane production in Brazil for conversion to ethanol could reduce current global CO 2 emissions by as much as 5.6%, according to a new study by an international team led by researchers from the University of Illinois. The corresponding range of CO 2 offsets is 0.55–2.0 Gigatons yr −1. This would displace 3.8–13.7%

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

Green Car Congress

The study considered emissions of non-methane hydrocarbons (NMHC), CO, NO x , PM 2.5 , sulfur dioxide (SO 2 ), and ammonia (NH 3 ), as well as the lifecycle climate impact of CO 2 and non-CO 2 greenhouse gases (GHG) on a CO 2 -equivalent basis. The researchers took an estimated range of this to be 0.5–2%
