Researchers at Queen’s Univ. suggest that policy makers examine greenhouse gas (GHG) emissions implications for energy infrastructure as fossil fuel sources must be rapidly replaced by windmills, solar panels and other sources of renewable energy.

An international team of researchers has identified a new theoretical approach that may one day make the synthesis of hydrogen fuel storage materials less complicated and improve the thermodynamics and reversibility of the system.

A discovery by scientists at the University of East Anglia could contribute to the development of systems that use domestic or agricultural waste to generate clean electricity. The researchers have demonstrated for the first time the mechanism by which some bacteria survive by "breathing rocks". The findings could be applied to help in the development of new microbe-based technologies such as fuel cells, or ‘bio-batteries’, powered by animal or human waste.

Derek Abbott, an Australian engineer, says that pure liquid or gas hydrogen is a much better energy solution than photovoltaics, or even hydrogen fuel cells. But isn’t it a little difficult to make? Not when paired with concentrated solar energy, he says, and the way to get it is very low-tech.

U of C chemists have taken the science behind a specific type of fuel cell towards a higher level of design. They have discovered a new material that allows a PEM fuel cell, known as a polymer electrolyte membrane fuel cell, to work at a higher temperature. This discovery is extremely important in terms of increasing the efficiency and decreasing the cost of PEM fuel cells.

Four chemists from the Univ. of Rochester
are building a three-module system that is intended to produce hydrogen from
water using carbon nanotubes and artificial photosynthesis. The invention
involves the use of chromophores, complex natural molecules that absorb
sunlight, that will be re-engineered to generate reducing electrons that will
be captured by a nanotube-suffused membrane. The project shows promise and has
received federal support.

Driven by 550-W hydrogen fuel cell, the 37-pound aircraft
built by the Naval Research Laboratory has set an unofficial endurance record
for an aircraft of its kind. The invention of certain new technologies,
including lightweight hydrogen storage tanks, has allowed fuel cell systems to
provide seven times the energy per weight of batteries.

Univ. of Florida chemists have pioneered a method to tease out promising molecular structures for capturing energy, a step that could speed the development of more efficient, cheaper solar cells. The work focuses on molecules known as dendrimers whose many branching units make them good energy absorbers. The amount of energy the synthetic molecules can amass and transfer depends on which path the energy takes as it moves through the molecule. The team demonstrated that it could use phased tailored laser pulses—light whose constituent colors travel at different speeds—to prompt the energy to travel down different paths.

A new ceramic material could help expand the applications for solid oxide fuel cells—devices that generate electricity directly from a wide range of liquid or gaseous fuels without the need to separate hydrogen.

Imagine a car that runs on hydrogen from solar power and produces water instead of carbon emissions. While vehicles like this won't be on the market anytime soon, Univ. of Wisconsin-Madison researchers are making incremental but important strides in the fuel cell technology that could make clean cars a reality.
