Discovery of mechanism for atmospheric particle formation suggests need for ammonia emission regulations

Green Car Congress

The presence of ammonia was first discovered in the upper troposphere in 2016 using the analysis of averaged MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) infrared limb-emission spectra. The emission sources are limited up there. To make clouds, you need water to nucleate or freeze.

PSI team develops web tool for consumers to compare environmental impact of passenger cars in detail

Green Car Congress

The entire life cycle of the passenger cars is taken into account, including the manufacture of the vehicles and the environmentally relevant emissions from driving. Depletion of fresh water reserves [m 3 ]. Noise emissions [Person-Pascal/second]. Sample results from Carculator. Depletion of fossil energy resources [kg oil-eq.].

Air pollutant emission 2010 limits exceeded in twelve EU Member States; road transport NOx a main factor

Green Car Congress

Twelve European Union Member States exceeded one or more of the emission limits set by the EU National Emission Ceilings (NEC) Directive, according to recent official data for 2010 reported to the European Environment Agency (EEA). In some instances the limits were exceeded by significant amounts. Finland exceeded its ammonia ceiling.

Audi partnering with Climeworks on CO2 direct air capture and storage

Green Car Congress

Water from the HellisheiĆ°i power plant then flows through the facility and transports the carbon dioxide roughly 2,000 meters below the surface of the Earth. The water returns to the cycle of the geothermal power plant. This uses a specially developed adsorbent to bind the CO 2 in the air.

15 countries agree to work toward 100% ZEV truck and bus sales by 2040

Green Car Congress

Fifteen countries have agreed to work together toward 100% zero-emission new truck and bus sales by 2040. Participants in this coordinated global effort agree that zero-emission trucks and buses are essential to reducing transport emissions, mitigating climate change, improving air quality, reducing the use of fossil fuels and energy costs.

LeclanchƩ to supply battery storage system for two hybrid-powered ferries

Green Car Congress

The two ships, each with a capacity of 700 passengers, will replace existing diesel-powered vessels and will be used to transport passengers between Switzerland and France with projected completion dates of 2022 and 2023. The water mist system integrates easily with existing water based fire suppression systems.

ETH Zurich: carbon-neutral fuel made from sunlight and air

Green Car Congress

CO 2 and water are extracted directly from ambient air via an adsorption/desorption process. At the heart of the solar reactor is a ceramic structure made of cerium oxide, which enables a two-step reaction—the redox cycle—to split water and CO 2 into syngas.
