Swiss team develops effective and low-cost solar water-splitting device; 14.2% solar-to-hydrogen efficiency

Green Car Congress

Their high production volumes have largely contributed to a price drop of 80% since 2008, currently reaching levels below $1 per watt peak. As the V OC of the presented c-Si cells is only ∼600 mV, four cells need to be connected in series to achieve stable water splitting performance. Schüttauf et al. Jan-Willem Schüttauf, Miguel A.

MIT Researchers Identify New Low-Cost Water-Splitting Catalyst

Green Car Congress

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. By doing so, he aims to imitate the process of photosynthesis, by which plants harvest sunlight and convert the energy into chemical form.

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.

Delivery of renewable isooctane to Audi tips interesting potential non-biomass pathway for biogasoline; “e-benzin” as solar fuel

Green Car Congress

Global Bioenergies, founded in 2008, has developed a synthetic isobutene pathway that, when implanted in a micro-organism, enables the organism to convert sugars (e.g., using just water, H 2 , CO 2 and sunlight. The process to convert isobutene to isooctane is well-established. Earlier post.). Earlier post.).

Genifuel Licenses High-yield Algae-to-Natural Gas Process from PNNL

Green Car Congress

Battelle is granting an exclusive license to Genifuel Corporation for a process developed at Pacific Northwest National Laboratory (PNNL) to convert algae into renewable synthetic natural gas (SNG) for use in pipelines and power generation. PNNL has tested the gasifier with terrestrial plants, kelp and water hyacinths.

Study Finds Controlling Soot May Be Fastest Method to Reduce Arctic Ice Loss and Global Warming; Second-Leading Cause of Global Warming After CO2

Green Car Congress

The most immediate, effective and low-cost way to reduce soot emissions is to put particle traps on vehicles, diesel trucks, buses, and construction equipment. Soot could be further reduced by converting vehicles to run on renewable electric power. Black carbon converts sunlight to heat and radiates it back to the air around it.

Genomatica Develops Bio-manufacturing Process for Methyl Ethyl Ketone; Potential Product for Struggling Corn Ethanol Plants

Green Car Congress

In the second half of 2008, on the heels of its first development of a process for 1,4-Butanediol (BDO), Genomatica targeted MEK and began development of the first organism known to bio-manufacture MEK from sugar in the laboratory. Genomatica will offer a licensing model to allow other manufacturers to directly produce MEK from the process.
