Researchers at the U.S. Department of Energy’s Idaho National Engineering and Environmental Laboratory and Ceramatec, Inc. of Salt Lake City are reporting a significant development in their efforts to help the nation advance toward a clean hydrogen economy.
Laboratory teams have announced they’ve achieved a major advancement in the production of hydrogen from water using high-temperature electrolysis. Instead of conventional electrolysis, which uses only electric current to separate hydrogen from water, high-temperature electrolysis enhances the efficiency of the process by adding substantial external heat – such as high-temperature steam from an advanced nuclear reactor system. Such a high-temperature system has the potential to achieve overall conversion efficiencies in the 45 percent to 50 percent range, compared to approximately 30 percent for conventional electrolysis. Added benefits include the avoidance of both greenhouse gas emissions and fossil fuel consumption.
“We’ve shown that hydrogen can be produced at temperatures and pressures suitable for a Generation IV reactor,” said lead INEEL researcher Steve Herring. “The simple and modular approach we’ve taken with our research partners produces either hydrogen or electricity, and most notable of all – achieves the highest-known production rate of hydrogen by high-temperature electrolysis.”

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
