ORNL team discovers mechanism behind direct ethanol-to-hydrocarbon conversion; implications for energy efficiency and cost of upgrading

Green Car Congress

The research, supported by DOE’s BioEnergy Technologies Office (BETO), has implications for the energy efficiency and cost of catalytic upgrading technologies proposed for use in bio-refineries. All these catalysts are robust to water content in ethanol (5–95%) and volatile impurities in fermentation stream. Casbeer, Robert A.

Sandia team boosts hydrogen production activity by molybdenum disulfide four-fold; low-cost catalyst for solar-driven water splitting

Green Car Congress

The improved catalyst has already released four times the amount of hydrogen ever produced by MoS 2 from water. Nevertheless, because of the scarcity and cost of Pt, a more abundant alternative is needed for cost-effective implementation. Water splitting is a challenging reaction. Then you can restart it with acid.

NREL shows graded catalytic-protective layer boosts longevity of high-efficiency photocathodes for renewable hydrogen

Green Car Congress

Researchers at the US Department of Energy’s National Renewable Energy Laboratory (NREL) have developed a method which boosts the longevity of high-efficiency photocathodes in photoelectrochemical water-splitting devices. A PEC cell absorbs sunlight and converts that energy into hydrogen and oxygen by splitting water molecules.

NREL sets new world efficiency record for solar hydrogen production: 16.2%

Green Car Congress

Scientists at the US Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) recaptured the record for highest efficiency in solar hydrogen production via a photoelectrochemical (PEC) water-splitting process.

$10-Trillion Investment Needed To Avoid Massive Oil Price Spike Says OPEC

Green Car Congress

The OPEC published its World Oil Outlook 2015 (WOO) in late December, which struck a much more pessimistic note on the state of oil markets than in the past. More to the point, the cost of electric vehicles will only decline in real dollar terms over time, and adoption should continue to rise in a non-linear fashion.

New bimetallic copper-titanium hydrogen evolution catalyst outperforms platinum by more than 2x

Green Car Congress

It is widely believed that room temperature electrochemical reduction of water to molecular hydrogen offers a significant promise for supplying CO 2 -free hydrogen, which can be used directly as a fuel or as reactant to convert CO 2 and to upgrade petroleum and biomass feedstocks to value-added chemicals and fuels through hydrotreating processes.

How Flyback Rocket Boosters Got Off the Ground

Cars That Think

For 125 years they had been used to pump water out of mines and then to power the mills of the Industrial Revolution. Such reusable rocketry is already cutting the cost of access to space and, with other advances yet to come, will help make it possible for humanity to return to the moon and eventually to travel to Mars.
