Index / Biomass/Biofuels

The United Nations Intergovernmental Panel on Climate Change has suddenly reversed its support for biofuels. The panel now admits growing crops for fuel poses risks to ecosystems and biodiversity. - Scientists and many Green activists turned against ethanol and biodiesel years ago because it took too much land. However, the United States and EU governments have kept their farmer subsidies. Environmentalism had suddenly become political payoff. The key science for the turnaround was supplied in 2008 by Princetonian Tim Searchinger in Science (Use of U.S. Croplands for Biofuels Increased Greenho... More →

Index / Biomass/Biofuels

A biofuel is a type of fuel whose energy is derived from biological carbon fixation. Biofuels include fuels derived from biomass conversion, as well as solid biomass, liquid fuels and various biogases.[1] Biofuels are gaining increased public and scientific attention, driven by factors such as oil price hikes and the need for increased energy security. However, according to the European Environment Agency, biofuels address global warming concerns only in specific cases.

Index / Biomass/Biofuels

Biomass, a renewable energy source, is biological material derived from living, or recently living organisms, such as wood, waste, and alcohol fuels. Biomass is commonly plant matter grown to generate electricity or produce heat. For example, forest residues (such as dead trees, branches and tree stumps), yard clippings and wood chips and garbage may be used as biomass. However, biomass also includes plant or animal matter used for production of fibers or chemicals. Biomass may also include biodegradable wastes that can be burnt as fuel. It excludes organic materials such as fossil fuels which... More →

Karla Lant reports that physicists at the University of Houston have discovered a low-cost, efficient, and easily available catalyst that can split water into hydrogen and oxygen. The catalyst is far more efficient than other options that have previously been employed, and because it is grown from ferrous metaphosphate on a conductive nickel foam platform, it is both more durable and cheaper to produce than other methods.

Cost-wise, it is much lower and performance-wise, much better, lead author and Anderson professor of physics Zhifeng Ren, M.D. told the University of Houston News.... More →
