ARPA-E awarding $30M to 12 hybrid solar projects; conversion and storage

Green Car Congress

Under the FOCUS program, projects will develop advanced solar converters that turn sunlight into electricity for immediate use, while also producing heat that can be stored at low cost for later use as well as innovative storage systems that accept both heat and electricity from variable solar sources. Earlier post.).

MIT Researchers Identify New Low-Cost Water-Splitting Catalyst

Green Car Congress

The Ni-B i films can be prepared with precise thickness control and operate at modest overpotential providing an alternative to the Co catalyst for applications in solar energy conversion. Nocera believes that as the team carries out further research even better compounds will come to light. The research is still in an early stage.

Berkeley Lab team creates “cyborgian” hybrid artificial photosynthesis system; CO2 to acetic acid at high yield

Green Car Congress

Their hybrid approach combines the highly efficient light harvesting of inorganic semiconductors with the high specificity, low cost, and self-replication and -repair of biocatalysts. Biologically precipitated cadmium sulfide nanoparticles served as the light harvester to sustain cellular metabolism. In contrast, the M.

DOE issues FOA for up to $4M for development of advanced H2 storage systems and materials

Green Car Congress

Most of the hydrogen that is used today is stored as a compressed gas (with pressures typically ranging from 150 to 700 bar) or a liquid (liquid storage requires cryogenic temperatures near 20 K). In addition, the costs associated with high-pressure fast refueling adds to the overall costs associated with using hydrogen fuel cells.
