Bacteria Could Power the Future

Everyday alternative energy scene is garnering bigger and important space in newspapers and industrial lives. People are feeling the need for greener energy and cleaner environment. Some researchers are focusing their attention on one of the ancient living organisms, the cyanobacteria.1 Comment

Algae Biofuels Of The Future

Algae fix the sunlight and carbon dioxide into energy and that too very fast. Scientists want to utilize this quality for alternative fuels. And when it comes to greener alternatives to fossil fuel what could be greener than pond scum? Why algae are more suitable over other bio-fuels? Algae can grow anywhere, practically anywhere. They can grow in sea-water or salty water or adulterated water or even in sewage. They can bear extreme temperature. They can grow on waste-land. Another good thing about algae is they multiply very fast. They can double their weight many times in a single day. Algae produce oil as a byproduct of photosynthesis. They can produce fifteen times more oil per acre than other plants such as corn and switchgrass. 18 Comments

Energy From Hydrogen-Producing Bacteria

Today we all are feeling the need of growing green. We have already put the various resources of planet earth on risk and some of the resources will not last for our great-great grandchildren for future use. So it’s better that we start mending our ways. Scientists from the Agricultural Research Service (ARS) and North Carolina State University (NC State) are in the process of developing new green technology that could lead to production of hydrogen from nitrogen-fixing bacteria. ARS inventors Paul Bishop and Telisa Loveless and NC State inventors Jonathan Olson and José Bruno-Bárcena developed the patent-pending technology. Bishop first demonstrated novel aspects of bacterial nitrogen-fixing more than two decades ago. 3 Comments

Energy From Electrogenic Grass Plants

Nicholas Albertini, a physics major from Lawrence University recently came up with an idea for a new renewable energy source. They propose that a plant be developed to generate an electrical current. The most likely base organism, suitable to be genetically engineered for this purpose, seems to be prairie grass (Poaceae stipoideae). Such grasses have the physiology, growth period, growing conditions and reproductive fitness needed for this use. The base organism will need to be genetically recombined with genes from other useful organisms or synthetic genes produced in the laboratory. 1 Comment

Anaerobic Digestion of Biomass

The generation and disposal of organic waste without adequate treatment result in significant environmental pollution. Besides health concerns for the people in the vicinity of disposal sites, degradation of waste leads to uncontrolled release of greenhouse gases (GHGs) into the atmosphere. Conventional means, like aeration, is energy intensive, expensive and also generates a significant quantity of biological sludge. In this context, anaerobic digestion offers potential energy savings and is a more stable process for medium and high strength organic effluents. Waste-to-Energy (WTE) plants, based on anaerobic digestion of biomass, are highly efficient in harnessing the untapped renewable energy potential of organic waste by converting the biodegradable fraction of the waste into high calorific gases. Apart from treating the wastewater, the methane produced from the biogas facilities can be recovered, with relative ease, for electricity generation and industrial/domestic heating. 16 Comments

Mariah Power – Low Cost Wind Energy

Wind energy is 'sustainable energy', just like solar energy and water power. We already know the benefits of wind energy and why we should opt for it. But currently manufacturers are concentrating on the drawbacks of the wind energy and trying to eliminate or minimize those shortcomings. For example turbines are noisy and this sound nuisance can be a problem for the residents of the areas. Wind turbines are unsafe for birds too. Birds can be injured or die if they are caught up in the wings of the turbines. Turbines might annoy you due to horizon pollution i.e. they might meddle with your aesthetic sense. 21 Comments

Bio-Fuel Market Set to Grow by 1,000%

Middle Eastern oil sheiks move over. There’s a new kid on the energy block! Bio-fuel is the new green, completely clean fuel source. It’s also known as “agro-fuel” and can be broadly defined as any solid, liquid or gas fuel consisting of or derived from biomass. Biomass is nothing more than materials that were recently living organisms—in this case, plants and their by-products. Even better, it is a renewable energy source, unlike petroleum and coal, which once used are gone forever. Thanks to a new miraculous feat of engineering and science, this energy source has suddenly become competitive with oil, catapulting it from a backyard business into a global economic phenomenon. 10 Comments

San Francisco Greasecycle Program

For the past several months the San Francisco Public Utility Commission (SFPUC) has begun picking up used cooking oil from restaurants and businesses for free in an effort to find fuel alternatives for its municipal fleet. The city hopes to expand the grease recycling program (called SFGreasecycle) to include small-scale household pickups and eventually power all city vehicles on biodiesel, including public buses and fire trucks. The oil is picked from local restaurants by SFPUC trucks, dropped off at a transfer station, filtered, transferred into a multi storage tank settling system, then decanted for three days. The oil is then sold to a biodiesel plant using bulk transport tractor-trailer pickups. 5 Comments

Harvesting Hydrogen from Farm Waste

The National Research Council of Canada's Biotechnology Research Institute has begun research and development of a process that will extract hydrogen from organic waste materials like fermentable feedstock and manure. The materials are processed to hydrogen by dark and photofermentation. The goal is to "come up with biosystems that could be grouped into a multiple-stage process to capture almost all the hydrogen from the primary feedstock". One dairy farm in Ontario is already producing power from manure using an anaerobic digester. 3 Comments

Are Biofuels Marginalizing Rural Women?

According to a study by the Food and Agriculture Organization of the United Nations, the recent and rapid increase in large-scale liquid biofuel production in third world countries could marginalize rural women by threatening their livelihoods. Traditionally, small farmers (women in particular) have had limited access to the large-scale plantations that are required for the production of biofuels like bioethanol and biodiesel. These include land and water, chemical fertilizers and pesticides. 13 Comments

Are Biofuels a Viable Alternative to Fossil Fuels?

With food-related riots erupting in many poor countries the debate surrounding biofuels have heated up again. How viable are they, considering numerous other options easily available to developed as well as developing and under-developed countries? 15 Comments

Ethanol Pipeline Proposed by Producers

Ethanol producers are considering whether a dedicated pipeline might be the best method for transporting the fuel. The ethanol industry is currently reliant upon traditional transport methods, such as railway and tanker truck, to ship the fuel across the states. Since ethanol plants must depend on rail or truck for distribution, the result has been a delay in getting the fuel additive to the pumps. The industry has therefore initiated a study of the developing problem and a suggestion for an ethanol pipeline is emerging. 9 Comments

Biodiesel Rental Cars from Bio-Beetle

Would you believe there exists a company that offers rental cars which are entirely powered by biodiesel? In support of their mission statement to be the "greenest" and "best" rental car company on the planet, Bio-Beetle Eco Rental Cars began their environmentally conscious business endeavor in 2003 with only a single car. The company was not, and still isn't, supported by a major car manufacturer. Powered by biodiesel, each Bio-Beetle has been purchased and developed individually by the founders as funds allow. The founders of Bio-Beetle believed their business venture was a great way to demonstrate environmental consciousness and have, therefore, slowly built the foundation for the only rental car company of its kind available. 6 Comments

Alternative Fuels Can Boost Pollution

A recent US study released on November 13, 2007, warns that somealternative fuels can cause more harmful greenhouse gas emissions than fossil fuel polluters like diesel or petrol. For example liquid coal, often touted as an alternative to gasoline and thus a way of reducing our dependence on foreign oil, can actual produce up to 80% more global warming pollution than typical unleaded gasoline. The process of turning coal into liquid (liquefaction by hydrogenation) actually produces nearly double the level of carbon dioxide emissions that conventional gasoline does, and it is considered by many environmentalists as a huge step backward for combating global warming. 4 Comments

Biotechonomy: Can We Grow Energy?

Today's TED Talk is brought to us by Juan Enriquez, chair and CEO of Biotechonomy, and an authority on economics and the political impact of science. Enriquez proposes that we look at 'growing energy' by accelerating the biological processes that produce fuel crops. He believes increased agricultural productivity and energy production can be achieved by understanding the role biology plays in producing traditional fuel sources like coal and oil. He also argues that we should stop extracting energy with 'brute force' and start using biological science and technology to process crude fuel sources in a sustainable way. 11 Comments

Sugar Cane Ethanol Hits Hollywood

The most recent episode of CBS' new Tuesday-night drama, CANE, was themed by the plans for a Florida-based sugarcane ethanol refinery. Lead character Alex (Jimmy Smits) had recently taken the reign as CEO to Duque Rum. Initially Alex was presented with the idea of selling off the company's sugarcane fields, a move that would allow the Duque Company to focus entirely on the production of its popular-selling rum. Instead Alex decides to meet with a US Senator over the future of sugarcane ethanol. The proposal by the federal government is to contract for the first US-based sugarcane ethanol refinery: a move that would cost $100 million but would be subsidized by half from the government. Although the cost is heavy, Alex explains to his family, sugarcane ethanol is the future and it would behoove the Duque family to retain their sugarcane fields and invest in the production of ethanol. 6 Comments

E85 Health Report Disputed

Phil Lampert, Executive Director of the National Ethanol Vehicle Coalition, responds to a recent health report about the potential health and pollution risks of e85 ethanol. The report warns of possible cancer and ozone-related health consequences of a large-scale conversion from gasoline to ethanol, comparing the effects of gasoline vehicle emissions with those from ethanol fuel. Lampert argues that the report's negative conclusions are unrealistic and he maintains that the NEVC will continue to support the use of e85 as a fuel source, along with all other fuel alternatives like biodiesel, propane, compressed natural gas, electricity, hydrogen and other yet-to-be defined fuels. 1 Comment

Biodiesel banned in Texas

Come December 31st, the Texas Commission on Environmental Quality (TCEQ) is set to effectively ban biodiesel in the state's largest markets. The problem, they say, lies with the fuel's nitrogen oxide (NOx) emissions and their contribution to the formation of ground-level ozone in Texas' eastern counties. According to the TCEQ, biodiesel does not meet the stricter NOx standards recently imposed on diesel and alternative diesel fuels under new regulations. Efforts to clean up the air, led the TCEQ in November 2005 to adopt Texas low emission diesel standards (TxLED) in an effort to reduce pollutants in the state's smoggiest 110 counties. Texas' biodiesel industry - the largest in the country - suddenly found itself essentially outlawed after the standards went into effect.23 Comments

Advantages of Biodiesel Fuel for Transportation

Modern diesel engine technology has advanced to the point where the advantages of biofuel usage are becoming much greater than the disadvantages. Modern diesel engines produce less noise, smoke or vibrations and they are more fuel-efficient than older model engines. Diesel engines have the added advantage of greater acceleration when compared to gasoline engines on the same model of vehicle. The use of biodiesel fuelmay be the solution to the increasing transportation energy crisis, particularly in the farming and shipping transportation sectors.

Mesquite to Ethanol Machine

Mesquite is a deciduous tree, commonly found in Northern Mexico and the United States. Because of its long roots and ability to flourish in dry climates, mesquite trees can be quite a frustrating nuisance for farmers and ranchers alike. Mesquite trees can use up a lot of water because their roots grow deep in order to tap into local water tables. This limits the growth of other important plant forms like grasslands for cattle grazing. A new technology promises to help solve this ongoing problem by harvesting and converting mesquite into ethanol fuel, which can then be used to power farm equipment and vehicles. 8 Comments

Recycling Waste Vegetable Oil – Easy?

It's almost too good to be true. Restaurants produce a large amount of waste vegetable oils. Currently they have to sell this grease to oil-recycling companies and are charged a pick-up fee for the service. These companies in turn recycle the grease and re-sell it on the commercial market for a profit. It is therefore relatively easy to find a free source for bio-waste from local restaurants. They would gladly have someone recycle their waste for free. This gives the small-scale biofuel user a great opportunity to decrease their fuel expenses while saving the environment - or does it? 44 Comments

Ethanol from Cellulosic Biomass

One of the barriers to the production of ethanol from cellulosic biomass is the toughness of the cellulosic structure, and its resistance to chemical and enzymatic hydrolysis and insolubility in most solvents. Accordingly, pre-treatment such as steam explosion to break down the structure is a necessary first step. Now, researchers at the Japan Agency for Marine-Earth Science and Technology have discovered that cellulose undergoes a transformation from a crystalline form to an amorphous gel-like one very similar to a starch gel in water at high temperature (320° C) and pressure 25 (MPa).
