All-in-one solar-powered tower makes carbon-neutral kerosene in the field at pilot-scale

Green Car Congress

We are the first to demonstrate the entire thermochemical process chain from water and CO 2 to kerosene in a fully-integrated solar tower system. Previous attempts to produce aviation fuels through the use of solar energy have mostly been performed in the laboratory. B) Photograph of the solar tower fuel plant during operation.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

Schematic overview of the primary black-carbon emission sources and the processes that control. the distribution of black carbon in the atmosphere and determine its role in the climate system. Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1

Rio Tinto to invest $1 billion over 5 years to help meet new climate change targets

Green Car Congress

Mining giant Rio Tinto will invest around $1 billion over the next five years to support the delivery of its new climate change targets and a company objective for net zero emissions from operations by 2050. Under these targets, Rio Tinto’s overall growth between now and 2030 will be carbon neutral.

Volkswagen and Audi launch sustainability programs for US introduction of e-Golf BEV and A3 e-tron PHEV; carbon offsets with 3Degrees and solar energy

Green Car Congress

These begin with an investment in carbon reduction projects via a partnership with 3Degrees to offset emissions created from e-Golf production, distribution and from the estimated emissions produced from keeping the vehicle charged through the initial 36,000 miles of its life. 3Degrees and carbon offsets. Volkswagen of America, Inc.

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). Surprisingly, this situation is reversed at high temperatures in molten carbonates, which allows the endothermic, electrolytic one pot synthesis, and precipitation of CaO. used three.

IEA: global carbon dioxide emissions have rebounded strongly

Green Car Congress

The Covid-19 crisis in 2020 triggered the largest annual drop in global energy-related carbon dioxide emissions since the Second World War, according to IEA data, but the overall decline of about 6% masks wide variations depending on the region and the time of year. But our numbers show we are returning to carbon-intensive business-as-usual.

Testing solar radiation management as a geoengineering technique

Green Car Congress

Solar radiation management (SRM) is one of the geoengineering techniques proposed as a potential means of offsetting some of the anthropogenic radiative forcing of climate as a means to reduce climate change. To take geoengineering methods like solar radiation management seriously, we need to build realistic models.
