ORNL advancing LDH sorbent to recover lithium from geothermal brine wastes

Green Car Congress

These plants pump hot water from geothermal deposits and use it to generate electricity. The LDH sorbent is made up of layers of the materials, separated by water molecules and hydroxide ions that create space, allowing lithium chloride to enter more readily than other ions such as sodium and potassium. The technique is very sensitive to hydrogen atoms, making it ideal for studying water.

Caltech engineers devise new thermochemical cycle for water splitting for H2; recyclable, non-toxic, non-corrosive and at lower temperatures

Green Car Congress

The thermochemical production of hydrogen and oxygen from water via a series of chemical reactions is of interest because it directly converts thermal energy into stored chemical energy (hydrogen and oxygen), and thus can take advantage of excess heat given off by other processes. Research on thermochemical water splitting cycles largely began in the 1960s and 1970s and involved nuclear reactors and solar collectors as the energy sources, the team notes in their paper.

Electrolyzed Water for More Efficient Fuel Production from Ethanol Waste Products

Green Car Congress

Using electrolyzed water rather than harsh chemicals could be a more effective and environmentally friendly method in the pretreatment of ethanol waste products to produce an acetone-butanol-ethanol fuel mix, according to research conducted at the University of Illinois. When ethanol is produced, distiller’s dried grain with solubles (DDGS) is a waste product. This is an example of less inhibitor production with electrolyzed water compared with the traditional method.

Novozymes launches commercial enzyme technology to convert waste oils into biodiesel

Green Car Congress

waste oils with high FFAs have not been a viable feedstock option. equivalent MeOH, 35°C/95°F, 2% water and 20 to 24 hours reaction time. The enzymatic process eliminates the need for sodium methoxide, one of the most hazardous chemicals in traditional biodiesel plants. The enzymatic process uses less energy, and the cost of waste oil as a feedstock is significantly lower than refined oils.

Brown Chemists Develop Process to Simplify Waste Vegetable Oil to Biodiesel Process, Chart Progress of Transesterification Reaction

Green Car Congress

Two chemists at Brown University have streamlined the conversion of waste vegetable oil (WVO) into biodiesel, eliminating the need for corrosive chemicals to perform the reactions. In a paper published in the RSC journal Organic & Biomolecular Chemistry , the chemists describe the waste vegetable oil-to-biodiesel conversion in a single reaction vessel using environmentally friendly catalysts and making the conversion six times faster than current methods.

UH team reports new catalyst efficiently produces hydrogen from seawater; promising for large-scale hydrogen production, desalination

Green Car Congress

Researchers say the device, composed of inexpensive non-noble metal nitrides, manages to avoid many of the obstacles that have limited earlier attempts to inexpensively produce hydrogen or safe drinking water from seawater. Anderson Chair Professor of physics at UH, said it also would work with wastewater, providing another source of hydrogen from water that is otherwise unusable without costly treatment.
