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

Green Car Congress

Researchers in Europe led by a team from ETH Zurich have designed a fuel production system that uses water, CO 2 , and sunlight to produce aviation fuel. 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. Zoller et al.

Climate Change is NSF Engineering Alliance’s Top Research Priority

Cars That Think

Since its launch in April 2021 , the Engineering Research Visioning Alliance has convened a diverse set of experts to explore three areas in which fundamental research could have the most impact: climate change; the nexus of biology and engineering; and securing critical infrastructure against hackers.

A New Energy-Efficient Hydrogel Pulls Water From Air

Cars That Think

Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. Atmospheric water harvesting draws water from humidity in the air. The material is a hydrogel, a polymer network that naturally retains a lot of water.

Solar-to-Jet-Fuel System Readies for Take-Off

Cars That Think

As climate change edges from crisis to emergency, the aviation sector looks set to miss its 2050 goal of net-zero emissions. Despite continual improvements in engine efficiencies, that number is projected to keep rising. A glimmer of hope, however, comes from solar fuels.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

Anthropogenic climate change confronts humanity with a challenge: How can we keep warm now as we try to prevent our world from overheating in the future? A Small Country with Large Heating Needs Big problems demand big solutions, and there is perhaps no bigger 21st-century problem than climate change.

UC Riverside researcher awarded $450K grant to study impact of black carbon particles on climate change and air quality

Green Car Congress

A University of California, Riverside assistant professor of chemical and environmental engineering has received a $450,000 grant to study the impact of air-polluting black carbon particles as a way to mitigate climate change. Clouds have an important role in climate change.

Columbia University engineers make breakthrough in understanding electroreduction of CO2 for conversion to electrofuels

Green Car Congress

Our findings about CO 2 activation will open the door to an incredibly broad range of possibilities: if we can fully understand CO 2 electroreduction, we'll be able to reduce our dependence on fossil fuels, contributing to the mitigation of climate change. —co-author Sathish Ponnurangam.
