With the fluctuating price of oil, a finite resource, and concerns over CO2 emissions, many energy companies and developers have turned to utilizing biomass as alternative fuel (biofuel). This trend is actually taking two pathways: using biomass to convert to ethanol to power automobiles (which has been around for awhile now), and, converting biomass to electricity to power electric (or hybrid) vehicles (a more recent alternative). The question of which path is most efficient, sustainable, and less carbon-intensive is an [...]
Wastewater treatment facilities end up dumping a lot of mud that is extracted from the in-flowing water. And, like everything else, that mud takes up space. Space that could be used for other things, even at the dumping yards. But researchers from the Rovira i Virgili University (URV) have suggested, and successfully shown, that the waste mud doesn’t need to be taken to a dumping ground; rather, it can be used as fuel.
Those of us who don’t live in developing countries might not always remember that the majority of the world still uses biomass-fired cookstoves that produce smoke and other toxins. It’s a serious problem–indoor air pollution kills 1.6 million people yearly. Enter the SCORE (Stove for Cooking, Refrigeration, and Electricity), a $33 cookstove developed by researchers at the University of Nottingham that doubles as an electrical generator.
Dow AgroScience’s proposed use of sulfuryl fluoride to sterilize soil in farm fields would release large amounts of a potent greenhouse gas, increasing the global warming effects of agricultural practices, says a group of scientists and activists.
Carbon Capture and Storage (CCS) has the potential to cut global Co2 emissions dramatically. We’re talking huge cuts. It has been estimated that a plant implementing CCS can cut emissions by 80-90 percent compared with a plant that doesn’t use CCS. Sounds great, right? Well, there are some some problems.
Cost is the number one challenge that CCS faces. “Applying it would significantly increase the cost of electricity beyond what society is likely willing to pay,” said Sarah Forbes, a World Resources Institute Senior Associate. Another challenge is that no fully integrated demonstrations have taken place. The pieces have been tested individually, but the entire puzzle is yet to be seen.
Forbes describes CCS and its current challenges in more detail:
Most odd stories relating to the environment tend to revolve around researchers and scientists and their slightly off the wall discoveries. But not so today. Today, in news of the weird – or at least slightly surreal – I bring you Daimler, the German automaker, who announced last week their very first hybrid car, the Mercedes Benz S Class. It’s a limousine.
Now, they’re organizing a day of of international climate action to spread the word and support “real climate solutions.” You can check out their video and learn about how to get involved right here:
In the constant push for ever newer and greener technology and energy, we sometimes forget that it is often both simpler and cheaper to revisit old techniques in new ways. And that’s exactly what a group of researchers in California has done.
The old saying “step on a crack, break your mother’s back” may not apply to sidewalks for much longer now that MIT researchers have figured out why concrete breaks down. As a result of the discovery, structures like buildings, bridges, and yes, sidewalks, could last for hundreds of years longer than they currently do. A nuclear waste container built to last 100 years could, for example, last 16,000 years.
Today at Noon, a Shell service station in Ottawa, Ontario will quietly begin selling cellulosic ethanol blended into regular gasoline. The biofuel is made locally from wheat straw, and as far as we know is the first time cellulosic ethanol has been made publicly available.
The new fuel will only be available for one month, starting on June 10th, but it’s a major step forward for the production of advanced biofuels. All gasoline purchased at the Ottawa station will be a blend of 10% cellulosic ethanol and 90% gasoline (CE10).
Diepenbeek, Belgium - On June 2, 2009, 365-Energy announced that the Katholieke High School of Limburg (KHLim) will begin deploying ChargePoint(TM) Network charging stations from the infrastructure manufacturer Coulomb Technologies as part of the first European Clean Mobility Center in Belgium.
Coulomb’s international partner 365-Energy will provide the charging stations and manage the ChargePoint Network for subscribers.
KHLim produces its own green energy through wind, heat and solar as part of its CO2 neutral area. The ChargePoint charge stations will be connected to KHLim’s own power grid, which will supply the necessary energy.
