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.

EPFL solar hydrogen system co-generates heat and oxygen

Green Car Congress

EPFL researchers have built a pilot-scale solar reactor that produces usable heat and oxygen, in addition to generating hydrogen with unprecedented efficiency for its size. This is the first system-level demonstration of solar hydrogen generation. Resources Holmes-Gentle, I., Tembhurne, S.,

Synhelion starts construction of DAWN demo plant to produce solar fuels

Green Car Congress

ETH Zurich spin-off Synhelion has started the construction of DAWN—its own industrial plant to produce synthetic fuels using solar heat. The production process—using only solar heat—was first demonstrated in 2019 in a mini-refinery on the roof of ETH Zurich. Earlier post.)

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

Green Car Congress

Audi Hungaria is thus the second of five Audi sites (after Audi Brussels) to achieve a neutral carbon balance, according to the company. We have a clear aim: that all Audi sites will have carbon-neutral operation by 2025. The remaining heat is generated through natural gas, with carbon neutrality assured thanks to bio-gas certificates.

MIT researchers boost efficiency of carbon capture and conversion systems

Green Car Congress

Researchers at MIT have developed a method that could significantly boost the performance of carbon capture and conversion systems that use catalytic surfaces to enhance the rates of carbon-sequestering electrochemical reactions. The movement through water is sluggish, which slows the rate of conversion of the carbon dioxide.

ORNL team develops carbon-nanotube-based superlubricity coating

Green Car Congress

Scientists at the Department of Energy’s Oak Ridge National Laboratory have developed a coating composed of carbon nanotubes that imparts superlubricity to sliding parts. The multiwalled carbon nanotubes coat the steel, repel corrosive moisture and function as a lubricant reservoir. Kumara et al. It’s like an engine without oil.
