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.

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.)

Synhelion raises CHF 22M (US$23.6M) to support scaling of solar fuel production

Green Car Congress

The proceeds of the investment round will accelerate the company’s growth and support the scaling and commercialization of Synhelion’s solar fuels technology. Synhelion is developing two pathways to solar fuels: Redox splitting. The thermochemical splitting of CO 2 and water in a two-step redox reaction yields carbon-neutral fuels.

Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

Researchers at Monash University in Australia have conducted a lifecycle analysis and net energy analysis (LCA/NEA) of a hypothetical large-scale solar-electrolysis plant for the production of green hydrogen. of hydrogen is currently produced via water electrolysis and only a fraction of this production is powered by renewable energy.

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.

ANL: life-cycle water consumption of fuel cell vehicles can be cut in half compared to that of conventional ICE vehicles

Green Car Congress

The life-cycle water consumption of fuel cell electric vehicles using hydrogen produced from natural gas with steam methane reforming is almost 50% less than the life-cycle water consumption of conventional internal combustion engine vehicles using gasoline, according to a study by researchers at Argonne National Laboratory (ANL).
