IBN scientists convert CO2 into methanol

Scientists at the Singapore-based Institute of Bioengineering and Nanotechnology (IBN) have made an unprecedented breakthrough in transforming carbon dioxide, a common greenhouse gas, into methanol, a widely used form of industrial feedstock and clean-burning biofuel. Using "organocatalysts", researchers activated carbon dioxide in a mild and non-toxic process to produce the more useful chemical compound.  Read More

Silicon pyramid structures etched for two minutes using hydrogen fluoride/hydrogen peroxid...

Solar power from photovoltaic cells are widely recognized as an integral part of a clean green future, and any development that can make these cells more efficient, no matter how small, assists in making this future a reality. A team of researchers at Georgia Tech have developed a surface treatment that boosts the light absorption of silicon photovoltaic cells by trapping light in three-dimensional structures and by making the surfaces self cleaning.  Read More

Where the river meets the sea - salt and freshwater could be used like a giant battery (Im...

Green energy comes in many guises these days, from wind-power to wave-power. One of the more compelling of the new kids on the eco-energy block is salinity power, which uses the concurrence of salt-water and freshwater in estuaries and marries it with the natural, effortless process of osmosis.  Read More

The Waste2tricity process

It’s common knowledge that the majority of electricity generation and waste disposal methods currently in widespread use are not very environmentally friendly. New British venture Waste2tricity aims to kill two environmentally damaging birds with one stone by taking carbon based waste, either municipal solid waste (MSW) or waste from business and industry, and converting it into clean electricity, thereby reducing the amount of rubbish going to landfill and potentially making a significant contribution to the UK electricity supply.  Read More

Fuel cell design breakthrough

A team of scientists from the Universidad Complutense de Madrid (UCM) has designed a new "super-lattice" material with incredibly high ion conductivity properties that could lead to the development of more efficient fuel cells capable of operating at room temperature.  Read More

Carbon Capture and Storage slashes CO2 emissions into the atmosphere, but requires an incr...

Carbon capture and storage is a climate change mitigation technology characterized by sporadic and unreliable government support and plagued with accusations that it will worsen the environmental disaster it seeks to address. Yet, despite the negative stigma, CCS has been labeled by the IPCC and the Stern Report as an essential measure in reducing the impact of fossil fuels. Gizmag's Kyle Sherer takes a closer look.  Read More

Fuel cell breakthrough promises cheaper eco-friendly cars

A team of Australian scientists has developed a new fuel cell prototype that could pave the way for a generation of much cheaper, more fuel efficient fuel-cells for powering eco-friendly cars. The new fuel cells feature a new cathode made from a conducting polymer rather than the expensive cathodes used in existing fuel cells.  Read More

Nature's SUV in its natural habitat. Between 57.1 and 117.9 million metric tonnes of carbo...

A study published in the Institute of Physics’ Environmental Research Letters section today claims that by converting livestock manure to biogas, the United States could reduce its greenhouse gas emissions and generate up to 108.8 billion kW h – 2.9% of the country’s total electricity requirement.  Read More

New research stirs corn-ethanol debate

A team of researchers from the University of Washington researched the impact on soil fertility and effects on food supply when fuels based on crops such as corn and soybeans are mixed with fossil fuels. They discovered that the large amounts of energy required to grow corn and then convert it to produce ethanol had a net energy gain that was modest and that corn-based ethanol was the worst offender amongst the alternative energy fuels.  Read More

A London black cab

May 23, 2008 While improvements in engine technology have led to a marked improvement in fuel efficiency and carbon emissions in vehicles running on internal combustion engines in recent years, even greater cuts in emissions need to be made to tackle the global environmental problems associated with them. We’ve seen commercial airlines turning to biofuels, trucks running on liquefied natural gas and buses using ethanol engines. One of the most promising solutions for the humble car of the future could is hydrogen fuel cell systems, with a number of car manufacturers investing heavily in development.  Read More
