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

Green Car Congress

That makes the fuel carbon neutral, especially if we use CO 2 captured directly from the air as an ingredient, hopefully in the not-too-distant future. In 2017, the team started scaling up the design and built a solar fuel-production plant at IMDEA Energy Institute in Spain. —Aldo Steinfeld. Zoller et al.

ORNL-led team uses carbon material derived from tire waste to convert used cooking oil to biofuel

Green Car Congress

Using a novel, reusable carbon material derived from old rubber tires, an Oak Ridge National Laboratory (ORNL)-led research team has developed a simple method to convert used cooking oil into biofuel. —Hood et al. The patent-pending, waste oil-to-biofuel conversion adds a new approach to waste tire recycling initiatives.

MIT researchers develop oxygen permeable membrane that converts CO2 to CO

Green Car Congress

MIT researchers have developed a new system that could potentially be used for converting power plant emissions of carbon dioxide into carbon monoxide, and thence into useful fuels for cars, trucks, and planes, as well as into chemical feedstocks for a wide variety of products.

Lightning Systems converting 35-foot diesel buses to battery-electrics in Boulder; cost-effective electrification

Green Car Congress

This project will be the first step for the City of Boulder and Via in realizing their combined goal of converting the HOP fleet of 35-foot transit buses to all-electric vehicles. People in Boulder are very interested in reducing the carbon footprint in all that we do. Recycle them and make buses out of buses. —Natalie Stiffler.

University of Utah engineers develop fast method to convert algae to biocrude

Green Car Congress

Algal biocrude obtained from CIJMs converts successfully into biodiesel, and cascades of CIJMs increase the net lipid production. In 2017, about 5% of total primary energy use in the United States came from biomass, according to the US Department of Energy. Yen-Hsun Tseng, Swomitra K. Mohanty, John D. McLennan, Leonard F.

Digging into the differences in carbon accounting for biofuels

Green Car Congress

The benefit to the climate of using biofuels as a substitute for fossil fuels has been sharply contested for years; much of the disagreement is based on the assumptions underlying the carbon accounting in the lifecycle analysis. Assuming that biogenic carbon flows are always in balance over a biomass product’s lifecycle—i.e.,
