New photochemical diode artificial photosynthesis system doubles efficiency of solar water splitting

Green Car Congress

Researchers in Canada have demonstrated a new photochemical diode artificial photosynthesis system that can enable efficient, unassisted overall pure water splitting without using any sacrificial reagent. overall water splitting reaction. These free charges split water molecules into hydrogen and oxygen. … in neutral (pH?~?7.0)

Researchers split water by altering photosynthetic machinery in plants; semi-artificial photosynthesis

Green Car Congress

A new study, led by academics at St John’s College, University of Cambridge, has used semi-artificial photosynthesis to explore new ways to produce and store solar energy. They used natural sunlight to convert water into hydrogen and oxygen using a mixture of biological components and manmade technologies. —Katarzyna Sokó?.

Georgia Tech team develops highly efficient multi-phase catalyst for SOFCs and other energy storage and conversion systems

Green Car Congress

The catalyst is also readily applicable to other energy storage and conversion systems, including metal-air batteries, supercapacitors, electrolyzers, dye-sensitized solar cells, and photocatalysis. The ions meet to make water, which exits the fuel cell. An open-access paper on their work appears in the journal Joule.

Monash team proposes roadmap to renewable ammonia economy; 3 generations of technology

Green Car Congress

Generation 3 avoids the need for the Haber-Bosch process entirely by direct electrochemical conversion of N 2 to NH 3. Over the last decade, momentum has been building to transform the Haber- Bosch (H-B) ammonia industry toward renewable sources of hydrogen, for example, from water electrolysis or solar thermal cycles.

DOE releases five-year strategic plan, 2014-2018; supporting “all of the above” energy strategy

Green Car Congress

The US Department of Energy (DOE) released its five-year 2014-2018 Strategic Plan. To achieve this first objective, DOE intends to pursue parallel strategies: Advance options for diverse energy resources and conversion devices for power. By the end of FY 2015, achieve best in class solar photovoltaic (PV) systems at $1.85/watt
