Novel inexpensive cobalt-nickel electrode for efficient water and urea electrolysis; yolk-shell nanoparticles

Green Car Congress

Electrolytic hydrogen production powered by renewable energy is seen as an environmentally friendly means to ameliorate global climate and energy problems. Both half reactions of water electrolysis—hydrogen and oxygen evolution—are unfortunately slow and require a lot of power. Zhang, S.L., and Lou, X.W.

Study projects thermoelectric power in Europe and US vulnerable to climate change due to lower summer river flows and higher river water temperatures

Green Car Congress

A study published in Nature Climate Change suggests that thermoelectric power plants (i.e., nuclear and fossil-fueled generating units) in Europe and the United States are vulnerable to climate change due to the combined impacts of lower summer river flows and higher river water temperatures.

EPA awards $6.6M to universities for black carbon research

Green Car Congress

million in grants to eight universities in support of black carbon research. Black carbon can affect the climate in the near term, and like other types of fine particles, can cause serious health effects such as cardiovascular and respiratory ailments. The US Environmental Protection Agency (EPA) has awarded more than $6.6

Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The study underscores the complex and sometimes conflicting ways in which fossil fuel burning affects Earth’s climate.

Stanford team reports new low-cost, non-precious metal catalyst for water splitting with performance close to platinum

Green Car Congress

Researchers at Stanford University, with colleagues at Oak Ridge National Laboratory and other institutions, have developed a nickel-based electrocatalyst for low-cost water-splitting for hydrogen production with performance close to that of much more expensive commercial platinum electrocatalysts. Pennycook, University of Tennessee.

New ORNL tool to assess global freshwater stress suggests that population growth could be a bigger factor in water availability than increasing temperatures

Green Car Congress

An Oak Ridge National Laboratory (ORNL) paper published in Computers & Geosciences outlines a process that might help to determine the relative importance of population increases vs. climate change. Our work establishes a new method to couple geographic information system data with global climate outputs and statistical analysis.

Petrobras and the Federal University of RN inaugurate a pilot plant to cultivate microalgae for biofuel

Green Car Congress

Petrobras and the Federal University of Rio Grande do Norte inaugurated a pilot plant in Extremoz (state of Rio Grande do Norte) for the cultivation of microalgae for biodiesel production. The project has identified approximately 10 species of microalgae capable of growing in oil production water and cultivated in tanks.
