Economic Feasibility of Sustainable Non-Food Feedstock Pongamia Pinnata Based Biodiesel Production

Pongamia has attracted the world's attention as a sustainable substitute for petroleum products and its ability to grow and reclaim marginal lands.

Obama's Climate Plan Is Leaking Methane

Natural gas production leaks methane along its entire supply chain - from drilling to storing, processing to distributing.

Energy from Agricultural Waste

Even a small farmer could join a co-op and get in on this trend. These co-ops are growing and are being promoted by organizations interested in furthering the cause of renewable energy.

Producing Cellulosic Ethanol

Ethanol production must move away from the exclusive use of corn, or any food crops, as a feedstock. Our technology will allow for biomass diversification, and the use of the most abundant biomolecule on Earth: cellulose.

A blow to corn-based biofuels

Biofuels made from the leftovers of harvested corn plants are worse than gasoline for global warming in the short term, a study shows, challenging the Obama administration's conclusions that they are a much cleaner oil alternative and will help combat climate change.

A $500,000 study paid for by the federal government and published Sunday in the peer-reviewed journal Nature Climate Change concludes that biofuels made with corn residue release 7% more greenhouse gases in the early years compared with conventional gasoline.

Biofuels are better in the long run, but the study says they won't meet a standard set in a 2007 energy law to qualify as renewable fuel.

The conclusions deal a blow to what are known as cellulosic biofuels, which have received more than a billion dollars in federal support but have struggled to meet volume targets mandated by law. About half of the initial market in cellulosics is expected to be derived from corn residue.

The biofuel industry and administration officials called the research flawed. They said that it was too simplistic in its analysis of carbon loss from soil, which can vary over a single field, and that it vastly overestimated how much residue farmers would remove once the market gets underway.

Using Algae to Produce Four Key Fuels

At Algenol, algae is combined with carbon dioxide, salt water and sunlight in Algenol's proprietary photobioreactor system to produce thousands of gallons of fuel per acre.

The Benefits of Converting Waste Heat to Power

Waste heat to electricity uses less fuel to produce a given energy output, and avoids transmission and distribution losses that occur when electricity travels over power lines. It also decreases the impact of outages when the power grid goes down.

Plastic to Fuel Conversion: An Elegant Solution to Two Major Environmental Concerns

The process relies on heat and pressure to break down the long hydrogen, carbon and oxygen polymers that make up plastics. From there, these elements are recombined into the shorter hydrocarbon chains that can be effectively burned as diesel or gasoline.

Residential And Commercial Refuse-Derived Fuel Waste To Energy

This report serves as an overview of gasification technologies processing municipal solid waste (MSW) that includes non-recycled plastic.

Cogeneration Goes Global

As CHP systems can tap into a wide array of fuels to operate including coal, biomass and natural gas, there are few restrictions on where they can be installed.

More to Biofuel Production than Yield

With supportive policies, we envision the ability to design agricultural landscapes to maximize multiple benefits.

Controlled Nuclear Fusion:
The Energy Source That Is Always A Few Years Away

In my opinion the potential payoff of nuclear fusion is too big and important for the world to ignore.

Technology to Aid Geothermal Industry Growth

By utilizing Web-based technology, organizations involved in geothermal energy can realize significant cost-savings, in a paperless environment, through efficiencies in critical aspects of projects.

Geothermal Energy: A Resource Waiting To Be More Fully Tapped

A discussion covering the geothermal context, power generation, ground source heat pumps and geothermal's potential for the future.

Using Microbes to Produce Biofuel

Liquid fuels derived from plant biomass are one of the best alternatives if an inexpensive means of commercial production can be found. Major research efforts are focusing on fatty acids, which are the energy-rich molecules in living cells that have been dubbed nature's petroleum.

Parker Hannifin Biogas Dehumidification System

Parker Hannifin Biogas Dehumidification System

The selection of effective biogas treatment equipment is important, both in optimizing the cogeneration of electrical and thermal energy, making the most of the available renewable energy, and reducing energy consumption and operating. Parker's solution is to dry the gas, firstly by cooling using a water-cooled heat exchanger working with an air-cooled water chiller and secondly, by removing the condensed water with a cyclonic water separator. The cooled gas can then be reheated to reduce the relative humidity and thus meet the technical demands of gas engines, turbines and other downstream equipment.
