Researchers develop titanium and copper heterostructured photocatalyst for conversion of CO2 into CH4

Green Car Congress

Under illumination for 6 hours, the optimized reduced titania-Cu 2 O photocatalyst enables 0.13% photoreduction of highly diluted CO 2 with water vapors to 462 nmol g ?1 What if we drew inspiration from photosynthesis, the process by which plants use sunlight to convert CO2 and water into useful chemicals?

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

Current emissions of anthropogenic greenhouse gases (GHGs) have already committed the planet to an increase in average surface temperature by the end of the century that may be above the critical threshold for tipping elements of the climate system into abrupt change with potentially irreversible and unmanageable consequences, the authors write.

BMW i Ventures invests in Prometheus Fuels; CO2 air-capture and conversion to carbon-neutral gasoline

Green Car Congress

By creating carbon-neutral gasoline from CO 2 captured from the air, Prometheus Fuels allows the climate impact of today’s internal combustion engines to be massively reduced immediately. The conversion of CO 2 to fuels in these inexpensive water-based systems has shown high faradic efficiencies for reduction of CO 2.

Prometheus CEO outlines tech advances that could make CO2-to-fuels renewable gasoline and jet price-competitive with fossil fuels

Green Car Congress

This is an important development because there is little time available to reduce CO 2 emissions sufficiently to avoid the worst effects of climate change. The conversion of CO 2 to fuels in these inexpensive water-based systems has shown high faradic efficiencies for reduction of CO 2. to C 2 fuel products such as ethanol.

US and China jointly announce GHG reduction targets; US to cut net GHG 26-28% by 2025, China to peak CO2 by ~2030

Green Car Congress

The Administration said the United States will submit its 2025 target to the Framework Convention on Climate Change as an “Intended Nationally Determined Contribution” no later than the first quarter of 2015. launching a new track on the interaction of energy and water (the energy/water ‘nexus’).
