MIT team outlines path to low-cost solar-to-fuels devices; the artificial leaf

Green Car Congress

A team of researchers at MIT has described a framework for efficiently coupling the power output of a series-connected string of single-band-gap solar cells to an electrochemical process that produces storable fuels. The original demonstration leaf in 2011 had low efficiencies, converting less than 4.7% Source: Winkler et al.

MIT Researchers Identify New Low-Cost Water-Splitting Catalyst

Green Car Congress

By doing so, he aims to imitate the process of photosynthesis, by which plants harvest sunlight and convert the energy into chemical form. Daniel Nocera and his associates have found another formulation, based on inexpensive and widely available materials, that can efficiently catalyze the splitting of water molecules using electricity.

Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. aligned with the low-cost systems engineering and.

MIT, Novogy team engineers microbes for competitive advantage in industrial fermentation; the ROBUST strategy

Green Car Congress

Researchers at MIT and startup Novogy have engineered bacteria and yeast ( Escherichia coli , Saccharomyces cerevisiae and Yarrowia lipolytica ) used as producer microbes in biofuel production to use rare compounds as sources of nutrients. However, this is not the case for the more advanced biofuels and biochemicals under development.

ARPA-E Selects 37 Projects for $106M in Funding in Second Round; Electrofuels, Better Batteries and Carbon Capture

Green Car Congress

Today’s technologies for making biofuels all rely on photosynthesis—either indirectly by converting plants to fuels or directly by harnessing photosynthetic organisms such as algae. This process is less than 1% efficient at converting sunlight to stored chemical energy. Electrofuels: Biofuels from Electricity. Engineering E.

US DOE awards more than $175M to 40 projects for advanced vehicle research and development

Green Car Congress

This project will optimize fuel-based control of novel combustion strategies in light- and heavy-duty vehicles to enable diesel-like efficiencies with ultra-low engine-out emissions. This project will develop a new process that enables low-cost, domestic manufacturing of magnesium. valve train vs. bearings). 3,500,000. .
