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.

SMUD Board of Directors adopts climate emergency declaration; carbon neutrality by 2030

Green Car Congress

The SMUD (2020 Sacramento Municipal Utility District) Board of Directors adopted a climate emergency declaration that commits to working toward an ambitious goal of delivering carbon-neutral electricity by 2030. Furthermore, SMUD has reduced the carbon intensity of its power mix, which is now 50% carbon-free on average.

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.)

UGA study finds black carbon aerosols from GDI engines will worsen public health, climate; need for GPFs

Green Car Congress

The gasoline direct injection (GDI) engine is one of the most prominent technologies car manufacturers adopted to achieve the fuel economy and carbon dioxide emission goals established in 2012 by the US Environmental Protection Agency. A strong absorber of solar radiation, black carbon exhibits significant climate warming properties.

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.

Pilot Project Sends Kelp–and Carbon–to the Seafloor

Cars That Think

At daybreak, the cranks pull the ring back up to the surface to soak up sunlight and carbon dioxide. The Climate Foundation , the Seattle-based company behind the project, has found that this deep cycling makes kelp grow three times as fast as it can when kept in shallow waters, as seaweed farmers do now.

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. solar generation exceeding electrolyzer capacity).
