Universal Hydrogen has flown a 40-passenger regional airliner using hydrogen fuel cell propulsion. In this first test flight, one of the airplane’s turbine engines was replaced with Universal Hydrogen’s fuel cell-electric, megawatt-class powertrain. The other remained a conventional engine for safety of flight.

Researchers from the Karlsruhe Institute of Technology (KIT) and their Canadian partners have designed a low-cost photoreactor design for solar-driven synthesis. The photoreactors have a low level of complexity, are readily manufacturable via mass fabrication techniques in polymers, and are easy to adapt to diverse photocatalysts.

In a paper in the journal Fuel , the researchers report that the Co-doped graphdiyne catalyst achieved nearly complete decomposition of ammonia at 550 ˚C, and the conversion rate remained stable over 18 h of continuous reaction. Ammonia is by its nature a high-density hydrogen carrier. —Liu et al.

and Princeton University’s Andlinger Center for Energy and the Environment have created a scalable photocatalyst that can convert ammonia into hydrogen fuel. This result demonstrates the potential for highly efficient, electrically driven production of hydrogen from an ammonia carrier with earth-abundant transition metals.

Researchers at The Ohio State University have used a chemical looping process to produce hydrogen from hydrogen sulfide gas—commonly called “sewer gas”. Hydrogen sulfide is emitted from manure piles and sewer pipes and is a key byproduct of industrial activities including refining oil and gas, producing paper and mining.

By using a water-lean post-combustion capture solvent, (N-(2-ethoxyethyl)-3-morpholinopropan-1-amine) (2-EEMPA), they achieved a greater than 90% conversion of captured CO 2 to hydrocarbons—mostly methane—in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and 2 pressure).

million to 10 industry-led projects to advance nuclear technologies, including two aimed at expanding clean hydrogen production with nuclear energy. A well-established downstream syngas-to-synfuel conversion process, such as Fischer-Tropsch synthesis, converts the syngas to liquid synfuel for a total projected cost of less than $4/gallon.
