Ryan Maass for UPI: Boeing has delivered its reversible solid oxide fuel cell, for generating clean electricity, to the U.S. Navy for testing.
The fuel cell system is designed to generate, compress and store hydrogen from renewable sources such as wind and solar to produce zero-emissions electricity.Boeing's delivery to the Navy follows 16 months of development.
The technology is capable of both producing and storing energy. The first unit was commissioned on the Southern California power grid prior to its installation on the Navy's 'microgrid' for further testing.
"This fuel cell solution is an exciting new technology providing our customers with a flexible, affordable and environmentally progressive option for energy storage and power generation," Boeing Advanced Technology Programs director Lance Towers said.
Boeing officials say they were able to develop the fuel cell using their experience with the energy systems used for their unmanned undersea vehicles. Cont'd...
Plug Power Acquires Full Control of 'HyPulsion' Hydrogen and Fuel Cell Business in Europe for $11.47 Million
Storing solar energy as hydrogen is a promising way for developing comprehensive renewable energy systems. To accomplish this, traditional solar panels can be used to generate an electrical current that splits water molecules into oxygen and hydrogen, the latter being considered a form of solar fuel. However, the cost of producing efficient solar panels makes water-splitting technologies too expensive to commercialize. EPFL scientists have now developed a simple, unconventional method to fabricate high-quality, efficient solar panels for direct solar hydrogen production with low cost.
The work is published in Nature Communications.
Many different materials have been considered for use in direct solar-to-hydrogen conversion technologies but "2-D materials" have recently been identified as promising candidates. In general these materials—which famously include graphene—have extraordinary electronic properties. However, harvesting usable amounts of solar energy requires large areas of solar panels, and it is notoriously difficult and expensive to fabricate thin films of 2-D materials at such a scale and maintain good performance.
Kevin Sivula and colleagues at EPFL addressed this problem with an innovative and cheap method that uses the boundary between two non-mixing liquids. The researchers focused on one of the best 2-D materials for solar water splitting, called "tungsten diselenide". Past studies have shown that this material has a great efficiency for converting solar energy directly into hydrogen fuel while also being highly stable. Cont'd...
