Chevrolet is currently featuring a story on the Rockingham County landfill, which is just outside of Harrisonburg, on their website detailing carbon-related projects that the company has invested in. The story is told in a short video featuring theoretical physicist Dr. Michio Kaku.
A recent case study in the State of Vermont suggests that deriving electricity from cow manure may be economically feasible. This small and largely agrarian state has no shortage of cows and dairy farms. It is conceivable that with the proper commitment from farmers, utilities, and government agencies, cow power could be a central part of the Vermont electric grid. The seven-year study was conducted by six dairy farms, and produced 12 million kilowatt hours of electricity per year.
The six dairy farms participated in the Central Vermont Public Service (CVPS) Corporation's Cow Power program. Energy consumers can choose to purchase their power from the participating farms, making it feasible for farmers to create their electricity. The farms operate generators that run on methane from cow manure, a renewable energy source and a beneficial use of an otherwise hazardous waste.
Virgin Atlantic today announced the development of a world-first low carbon aviation fuel with just half the carbon footprint of the standard fossil fuel alternative.
The ground breaking partnership with LanzaTech represents a breakthrough in aviation fuel technology that will see waste gases from industrial steel production being captured, fermented and chemically converted using Swedish Biofuels technology for use as a jet fuel. The revolutionary fuel production process recycles waste gases that would otherwise be burnt into the atmosphere as carbon dioxide.
Extremophiles are tiny microbes that are able to thrive in hot, salty and even acidic or gaseous environments that would kill other forms of life. Now scientists are using these hardy dwellers of the seafloor and hot springs to produce biofuels like ethanol more efficiently and at lower cost.
These heat and salt-loving microorganisms are good at breaking down biological material like wood chips, waste crops or other sorts of plant material. They also literally "take the heat" when it comes to punishing industrial processes. Until recently, researchers have had trouble culturing these wild-growing extremophiles and harnessing their properties. But recent advances have allowed them to turn them into bio-powered refineries.
A pilot waste-to-energy system constructed by Duke University and Duke Energy this week garnered the endorsement of Google Inc., which invests in high-quality carbon offsets from across the nation to fulfill its own carbon neutrality goals.
The system, on a hog finishing facility 25 miles west of Winston-Salem, converts hog waste into electricity and creates carbon offset credits.
Waste-to-energy solutions are among the most attractive options for renewable energy.
Turning a waste product into useful energy is a win-win, saving disposal costs while simultaneously providing renewable energy. A whole range of these systems are either available or under development -- see our Biomass section for more information on some of these. But this article and video from the NSF recently caught my eye as a potentially outstanding breakthrough.
Humans should have a little more respect for dirty toilet water. In recent years, wastewater has become something of a commodity, with nuclear plants paying for treated wastewater to run their facilities, cities relying on so-called "toilet to tap" technology, and breweries turning wastewater into biogas that can be used to power their facilities. Soon enough, wastewater-powered batteries may even keep the lights on in your house or, at the very least, in the industrial plants that clean the wastewater.
