NASA launches search for greener propellant

NASA has put out the call for greener propellant fuel for use on the spacecraft of the future. Though it does not appear that NASA has stipulated that alternative propellants must match the performance of current mainstay hydrazine, it's clear that only high-performance substances need apply. Environmental credentials are where the new fuel must demonstrate an edge over hydrazine, which is a corrosive, toxic pollutant. As well as the environmental benefits, use of greener propellants should prove more economical, reducing the need for involved safety procedures that can lengthen launch times.Read More

Virgin claims its new jet fuel will have half the carbon footprint of others

Three years ago, Virgin Atlantic Airways grabbed some headlines when it experimentally ran one of its 747s on a mixture of standard jet fuel and biofuel. While some called it a publicity stunt, it was the first time that a commercial airliner had flown using biofuel – albeit only in part of one of its four fuel tanks. Today, however, the airline announced that it’s developing an aviation fuel that will have half the carbon footprint of conventional fuel. The carbon savings won’t result from how cleanly the fuel burns, but from how it’s obtained.Read More

Plastic2Oil process turns plastic waste into fuel

While a lot of people may be doing their part for the environment by sending their discarded plastic items off for recycling, the fact is that much of the plastic currently in use is non-recyclable. In a not particularly eco-friendly process, some of this plastic is burned to generate electricity, while much of it simply ends up in landfills. Canadian company JBI, however, has developed a process that uses those plastics as a feedstock, and turns them into fuel.Read More

Microwaves utilized to convert used motor oil into fuel

It has been estimated that over 8 billion US gallons (30.3 billion liters) of used motor oil are produced every year by the world’s cars and trucks. While some of that is re-refined into new oil or burned in furnaces for heat, neither of those processes are entirely environmentally-innocuous. In other cases, it is simply discarded. Today, however, researchers from the University of Cambridge announced the development of a process that uses microwaves to convert waste oil into vehicle fuel.Read More

Researchers use bacteria to produce potential gasoline replacement directly from cellulose

With the situation in Libya causing a spike in fuel prices worldwide there's some good biofuel-related news out of the U.S. Department of Energy's BioEnergy Science Center (BESC) that could help to reduce many countries' dependence on oil imports. For the first time, BESC researchers have succeeded in producing isobutanol directly from cellulosic plant matter using bacteria. Being a higher grade of alcohol than ethanol, isobutanol holds particular promise as a gasoline replacement as it can be burned in regular car engines with a heat value similar to gasoline.Read More

Breakthrough solar reactor makes fuel from sunlight

Because conventional photovoltaic panels produce electricity directly from sunlight, the energy they generate must either be used as it is produced or stored – either in batteries or by using the electricity to produce a fuel that acts as a storage medium for the energy. Now U.S. and Swiss researchers have developed a prototype device that directly converts the Sun’s rays into fuels that can be stored, allowing the energy to be used at night or transported to locations where it is needed.

MicroFusion Reactor lets you home-brew ethanol

A lot of people try to lessen the load on the local landfill by putting their organic waste in a compost heap, but soon there may be something else they can do with it – feed it to an E-Fuel MicroFusion Reactor. The new device, so we’re told, takes cellulosic waste material and breaks it down to nothing but sugar water and lignin powder within two minutes. The lignin powder can be used by pharmaceutical manufacturers (although it’s not clear how you’d get it to them), while the sugar water can be distilled into ethanol fuel. That’s where one of E-Fuel’s other products, the MicroFueler, comes in. Read More

Engineers creating carbon-negative Mars rocket

It may be called the Red Planet, but that doesn’t mean you can’t use green technology to get there. Engineers at the University of Hertfordshire are developing a miniature dual fuel rocket, as a test model for technology that could one day result in a full-scale carbon negative rocket capable of a return flight to Mars. Their model’s motor will be powered by a mixture of carbon dioxide and aluminum, turning the CO2 into carbon in the process - this is the opposite of what is done by traditional rockets.Read More

'Never-before-seen material' can store vast amounts of energy

Using super-high pressures similar to those found deep in the Earth or on a giant planet, researchers from Washington State University (WSU) have created a compact, never-before-seen material capable of storing vast amounts of energy. Described by one of the researchers as “the most condensed form of energy storage outside of nuclear energy,” the material holds potential for creating a new class of energetic materials or fuels, an energy storage device, super-oxidizing materials for destroying chemical and biological agents, and high temperature superconductors.
