NREL, Berkeley Lab propose efficiency and stability best-practices for solar water-splitting

Green Car Congress

Scientists from the US Department of Energy’s National Renewable Energy Laboratory (NREL) and Lawrence Berkeley National Laboratory (Berkeley Lab) are providing researchers with a guide to how best to measure the efficiency of producing hydrogen directly from solar power. PEC water-splitting was first noted in scientific publications in 1972.

All-in-one solar-powered tower makes carbon-neutral kerosene in the field at pilot-scale

Green Car Congress

Researchers in Europe led by a team from ETH Zurich have designed a fuel production system that uses water, CO 2 , and sunlight to produce aviation fuel. We are the first to demonstrate the entire thermochemical process chain from water and CO 2 to kerosene in a fully-integrated solar tower system. Zoller et al.

National Alliance for Water Innovation to lead DOE energy-water desalination hub

Green Car Congress

The US Department of Energy (DOE) selected the National Alliance for Water Innovation (NAWI) to lead a US Department of Energy (DOE) Energy-Water Desalination Hub that will address water security issues in the United States. This suite of technologies will treat “non-traditional” water sources for multiple end-use applications.

NREL researchers capture excess photon energy to produce solar fuels; higher efficiency water-splitting for H2

Green Car Congress

The advancement could significantly boost the production of hydrogen from sunlight by using the cell to split water at a higher efficiency and lower cost than current photoelectrochemical approaches. The research is outlined in a paper in Nature Energy. Beard and other NREL scientists in 2011 published a paper in Science that. Pach, Ashley R.

NREL sets new world efficiency record for solar hydrogen production: 16.2%

Green Car Congress

Scientists at the US Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) recaptured the record for highest efficiency in solar hydrogen production via a photoelectrochemical (PEC) water-splitting process. Structure of an IMM photocathode configured for water splitting with TEM cross-section of the active layers.
