Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

One way this could be achieved is by using photoelectrochemical (PEC) water splitting which directly converts water and sunlight to solar fuel (hydrogen). Cost effective solar fuel generation is hindered by the semiconductor material not meeting certain essential criteria to achieve highly efficient solar to hydrogen conversion.

ARPA-E to award up to $25M for work on WBG power semiconductor devices

Green Car Congress

Their widespread adoption, enabled by low-cost, high-performance power electronics could yield up to a 20% reduction in U.S. Automotive: High costs have thus far prevented the widespread electrification of vehicles. Achieving high power conversion efficiency requires low-loss power semiconductor switches.

DOE Announces $100M Available for ARPA-Es 3rd Funding Opportunity; Focus on Grid-Scale Energy Storage, Electrical Power Technology, and Building Energy Efficiency

Green Car Congress

ARPA-E seeks to invest in materials for fundamental advances in soft magnetics, high voltage switches, and reliable, high-density charge storage. Deploying advanced power electronics could provide as much as a 25-30% reduction in electricity consumption—or 12 % of total US energy consumption.

note the potential of each technology and explain what advances must occur with each if they’re ultimately to be deployed. To be successful, systems will need to evolve—in some cases, considerably—to compete financially with the cost of natural gas production. In their study, Yang et al. Credit: ACS, Yang et al.

million vehicles, and we’re seeing about half of people use it so far. For a while there, we were training-constrained in our progress, and we are, at this point, no longer training-constrained, and so we’re making rapid progress. We’re making sure that we’re being efficient as possible in our training.
