Researchers create hydrogen fuel from seawater

Read the full story from Stanford University.

Splitting water into hydrogen and oxygen presents an alternative to fossil fuels, but purified water is a precious resource. A team has now developed a way to harness seawater — Earth’s most abundant source — for chemical energy.

 

Japan Is Betting Big On The Future Of Hydrogen Cars

Read the full story from NPR.

It may feel like the electric car has been crowned the future of transportation.
Auto companies have plans to make more electric car models, and sales — still only a tiny fraction of the overall market — are expected to get a boost as more countries pass regulations to reduce carbon emissions. But Japan isn’t sure that the battery electric car is the only future, and it’s betting big on something it says makes more sense in big cities: hydrogen fuel cell vehicles.

Scientists use Nobel-prize winning chemistry for clean energy breakthrough

Read the full story in Science Daily.

Scientists have used a Nobel-prize winning Chemistry technique on a mixture of metals to potentially reduce the cost of fuel cells used in electric cars and reduce harmful emissions from conventional vehicles. The researchers have translated a biological technique to reveal atomic scale chemistry in metal nanoparticles. These materials are one of the most effective catalysts for energy converting systems such as fuel cells.

Lignin: A supergreen fuel for fuel cells

Researchers from the Laboratory of Organic Electronics at Linköping University have developed a fuel cell that uses lignin, a cheap by-product from paper manufacture and one of the most common biopolymers.

U.S. Department of Energy Guide to Alternative Fuels and Advanced Vehicles

More than a dozen alternative fuels are in production or under development for use in alternative fuel vehicles and advanced technology vehicles. Government and private-sector vehicle fleets are the primary users of these fuels and vehicles, but consumers are increasingly interested in them. Using alternative fuels and advanced vehicles instead of conventional fuels and vehicles helps the United States reduce petroleum use and vehicle emissions.

Mix and match MOF

Read the full story from Pacific Northwest National Laboratory.

Inexpensive materials called MOFs pull gases out of air or other mixed gas streams, but fail to do so with oxygen. Now, a team has overcome this limitation by creating a composite of a MOF and a helper molecule in which the two work in concert to separate oxygen from other gases simply and cheaply.

The results, reported in today’s Advanced Materials, might help with a wide variety of applications, including making pure oxygen for fuel cells, using that oxygen in a fuel cell, removing oxygen in food packaging, making oxygen sensors, or for other industrial processes. The technique might also be used with gases other than oxygen as well by switching out the helper molecule.

Argonne researchers develop new non-precious-metal fuel cell catalyst with performance comparable to platinum

Read the full post at Green Car Congress.

Researchers at the US Department of Energy’s Argonne National Laboratory have developed a new fuel cell catalyst using earth-abundant materials with performance that is comparable to platinum in laboratory tests. The nanofibrous non-precious metal catalyst (NPMC) is synthesized by electrospinning a polymer solution containing a mixture of ferrous organometallics and metal-organic frameworks and then is thermally activated.

Big box stores could ditch the grid, use natural gas fuel cells instead

Large facilities like big box stores or hospitals could keep the lights on by using a fuel cell that runs off the natural gas that already flows in pipelines below most city streets.
Instead of drawing electricity from the power grid, facilities could use natural gas-powered solid oxide fuel cells to lower their electric costs, increase power reliability, reduce greenhouse gas emissions, and maybe even offset costs by selling excess fuel cell-generated power back to the power grid. Such an energy future could be possible — assuming fuel cell lifespans are improved and enough systems are produced to reach economies of scale — according to a cost-benefit analysis published in the journal Fuel Cells.

IUPUI Earns Funding For Fuel Cell Technology

Purdue School of Engineering and Technology at IUPUI researchers have been awarded a nearly $600,000 grant from the National Science Foundation. The funding will be used to develop and market bio-ethanol fuel cell technology.

Winners of Hydrogen Student Design Contest Turn Urban Waste into Energy

Read the full story at The Energy Blog. Registration for the 2013 Hydrogen Student Design Contest is open until October 1, 2012.

How do you combine urban waste, hydrogen, and heat recovery into one power system?

A team of University of Maryland undergraduate and graduate engineering students designed a solution to this question as part of the Hydrogen Student Design Contest — a competition supported by the Energy Department to challenge university students to design hydrogen energy applications for real-world use. With a different theme every year, this year’s contest required teams to plan and design a combined heat, hydrogen, and power (CHHP) system (also known as a “tri-generation” system) for their university campus using local resources.

The Maryland team, which won for its tri-generation design, had to think creatively to overcome a challenge associated with its campus’s urban location. During the first phase of the contest — developing a feedstock analysis — the students realized their campus didn’t have enough waste to produce sufficient energy for the fuel cell system design. As an innovative solution, they opted to use waste from the nearby City of College Park in addition to their campus source to feed their CHHP design.
