Inverter Testing and Certification for Global Markets

Inverters/converters are a key element of most renewable energy systems where the power generated is not suitable to either be used locally or to provide power directly to the electric utility. Many renewable sources such as photovoltaics generate DC power, while some renewable sources such as wind turbine systems generate AC, but not at the same voltage and/or frequency required by the utility.

Hybrid Solar System For Rooftop Hydrogen

Instead of systems based on standard solar panels, Duke University engineer Nico Hotz proposes a hybrid option in which sunlight heats a combination of water and methanol in a maze of glass tubes on a rooftop. After two catalytic reactions, the system produces hydrogen that can be stored and used on demand in fuel cells.

Making Durable Synthetic Catalysts for Energy Storage

Pacific Northwest National Laboratory (PNNL) researchers have used a common protein to guide the design of a material that can make hydrogen gas. The synthetic material works ten times faster than the original protein found in water-dwelling microbes - clocking in at 100,000 molecules of hydrogen gas every second.

Understanding How the Ocean Impacts Climate Change

Lisa Collins, an environmental studies lecturer at the University of Southern California, spent four years collecting samples from floating sediment traps in the San Pedro Basin off the Los Angeles coast, giving scientists a peek at how much carbon is locked up in the ocean and where it comes from.
