Lignin is a complex chemical compound (a cross-linked amorphous phenolic polymer) and is the biomass component with highest energy content (9,000 - 11,000 Btu/lb compared to 7,300 - 7,500 for cellulose, Johnson 2002). Chevron says tests have shown that this produced water does not inhibit the lignin conversion.
Water splitting provides ions that continuously regenerate the ion exchange resin and enables electrochemical solution pH control. RW-EDI has many potential uses including direct production and separation of products, product purification, desalination, salt waste recovery, and water recycling. Top: RW-EDI stack.

Unintentional emission sectors: Coal burning, ferrous- and non-ferrous (Au, Cu, Hg, Pb, Zn) metal production, cement production. The session is expected to culminate in the adoption of a new convention by the 147 states attending the session to reduce mercury emissions and releases to the air, water and land. Source: UNEP.
Unlike coal-fired and natural gas-fired power generation plants, geothermal plants produce virtually no greenhouse gas emissions. The geothermal fluid heats a working fluid, such as isobutane or other organic fluids such as pentafluoropropane, which boils at a lower temperature than water. Bliem and G.L.
The glacial melt feeds rivers in China and throughout the Indian subcontinent and provide fresh water to more than one billion people. The pattern is very similar to a study Menon led in 2002, which found that black carbon led to droughts in northern China and extreme floods in southern China.
Methanol, like ethanol, is an alcohol with inherent issues such as its solubility in water and corrosiveness. About two-thirds of China’s methanol feedstock is produced from coal and the remainder from coking gas (a by-product of steel production) and natural gas. Methanol in China.
Hydrogen produced by water electrolysis has the potential to be a useful means of storing excess electricity generated using wind, solar, and other intermittent renewable energy. Integrated renewable hydrogen systems and public-private community-based partnerships. The 2015 cost target was $2-$3/gge.
The 7 awards bring the total number of GCEP-supported research programs to 104, with total funding of approximately $125 million since the project’s launch in 2002. The goal is to design a novel fuel cell that uses coal and water to generate hydrogen, water and a stream of carbon dioxide gas, which can be captured and sequestered.
He started at CNET News in 2002, covering IT and Web development. by homercles82 April 7, 2009 11:23 AM PDT Yes we will just be charging these cars using electricity that is made from naturla gas and coal fired palnts while we ignore nuclear unlike most of Europe. Before that, he was executive editor at IT publication InfoWorld.
February, 2009 : Record heat waves in late January and early February overloaded urban energy, water, and transport systems in the southernmost states of South Australia and Victoria and intensified hundreds of seasonal and man-made bushfires throughout the countryside, killing 374 people.
Denmark did that with Wind Power and now most of their energy comes from wind rather than oil, natural gas, or coal. I had surmised this in my 2002 car design thesis [link] even before anyone was talking about plug in series hybrids. We should have built more Nuclear power plants and created a nuclear waste recycling program.
