Audi Hungaria starts operation of Europe’s biggest solar roof installation

Green Car Congress

The remainder is compensated by bio-gas certificates. The first is the switch to green power, which has taken place thanks to the commissioning of Europe’s biggest photovoltaic roof installation and the supply of electricity from renewable sources. Since the start of the year, the site in Gy?r r has used only green power.

GWU team develops cost-effective solar process to produce lime for cement without CO2 emission

Green Car Congress

Conventional thermal decomposition production of lime (left) versus STEP direct solar conversion of calcium carbonate to calcium oxide (right). Conducive to our new solar process, electrolysis of molten carbonates forms oxides, which precipitate as calcium oxide when mixed with calcium carbonate. Click to enlarge. —Licht et al.

EIA: CO2 emissions from US power sector have declined 28% since 2005

Green Car Congress

US electric power sector CO 2 emissions have declined 28% since 2005 because of slower electricity demand growth and changes in the mix of fuels used to generate electricity, according to the US Energy Information Administration (EIA). If electricity demand had continued to increase at the average rate from 1996 to 2005 (1.9%

WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

A team of biologists and engineers modified Rhodopseudomonas palustris TIE-1 (TIE-1) so that it can produce a biofuel using only three renewable and naturally abundant source ingredients: carbon dioxide, solar panel-generated electricity and light. We hope that it can be a steppingstone for future sustainable solar fuel production.

Molten carbonate electrolysis can produce a range of carbon nanomaterials, including graphene, from CO2 at high yield

Green Car Congress

In the Solar Thermal Electrochemical Process (STEP), developed by Professor Stuart Licht and his group at GWU, solar UV–visible energy is focused on a photovoltaic device that generates the electricity to drive the electrolysis, while concurrently the solar thermal energy is focused on a second system to generate heat for the electrolysis cell.

New highly efficient catalyst for photoelectrochemical CO2 reduction toward methane

Green Car Congress

The work, presented in a paper in Proceedings of the National Academy of Sciences (PNAS), offers a unique, highly efficient, and inexpensive route for solar fuels synthesis. The solar-powered catalyst is made from abundant materials and works in a configuration that could be mass-produced. 1 under air mass 1.5 —Zhou et al.

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

This synthesis consumes only CO 2 and electricity, and is constrained only by the cost of electricity. unusually high electrical conductivity and Raman spectra of these materials demonstrated in the linked Data in Brief paper are that of multi-walled carbon nanotubes, and are due to the morphology as demonstrated by TEM.
