A long-lasting obstacle of solid oxide fuel cells has been overcome

One of the major drawbacks of carbon-fueled battery cells is the intrinsic presence of CO2, which impedes CO oxidation and, therefore, lowers the energy density of the cell. Researchers describe a novel dual-phase ion-conducting ceramic membrane that is absolutely gas-tight but highly permeable for CO2.

NREL reports examine economic trade-offs of owning versus leasing a solar photovoltaic system

Two new reports from the Energy Department's National Renewable Energy Laboratory (NREL) examine the economic options customers face when deciding how to finance commercial or residential solar energy systems. NREL analysts found that businesses that use low-cost financing to purchase a photovoltaic (PV) system and homeowners who use solar-specific loans can save up to 30 percent compared with consumers who lease a PV system through a conventional third-party owner.

New material, technique efficiently produce hydrogen, syngas fuel feedstock

A team of chemical engineering researchers has developed a technique that uses a new catalyst to convert methane and water into hydrogen and a fuel feedstock called syngas with the assistance of solar power. The catalytic material is more than three times more efficient at converting water into hydrogen gas than previous thermal water-splitting methods.
