Study Finds Stratospheric Water Vapor Is An Important Driver of Decadal Global Surface Climate Change

Green Car Congress

Decadal warming rates arising from (i) greenhouse gases and aerosols alone (black); (ii) that obtained including the stratospheric water decline after 2000 (red); and (iii) including both the stratospheric water vapor decline after 2000 and the increase in the 1980s and 1990s (cyan). Stratospheric water vapor and radiative processes.

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.

QUANTRON introduces new CIZARIS 12m electric bus; BEV first, fuel cell model next year

Green Car Congress

The vehicle-mounted and water-cooled central motor from Dana/TM4 based on the permanent synchronous principle (PSM) features low speeds and particularly high efficiency compared with asynchronous motors. This range is fully sufficient for most transport operators, saving them greater expense on charging infrastructure.

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

Green Car Congress

The system will graph lifecycle impact for a range of specified powertrains, for a large number of impact categories: Climate change [kg CO 2 -eq.]. Depletion of fresh water reserves [m 3 ]. The top sample above shows climate change impact; the subsequent chart shows human toxicity. Sample results from Carculator.

MUCHACHAS study finds aging of organic aerosols is caused by OH radicals; climate models need to be updated

Green Car Congress

An international team of researchers has discovered that chemical aging determines to a major extent the concentration and the characteristics of organic aerosol particles, which have a significant effect on climate. To date, this aspect has not been accounted for in regional and global climate models.

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. —Aldo Steinfeld.

MAN Diesel & Turbo partners with ABB to develop and commercialize new electro-thermal stationary energy-storage system

Green Car Congress

MAN Diesel & Turbo Schweiz AG has signed a cooperation agreement with ABB Switzerland for the development, production and commercialization of a three-way energy-storage system. The biggest challenge in building stable, climate-neutral energy systems is the intermittency of renewable energy in power generation and supply.
