Catalytic Membrane Reactor for H2-Production from Ammonia

The ability to store massive amounts of dispatchable energy is key for the development of reliable and flexible energy systems, particularly under the new energy concept where large renewable power plants increasingly farther from end users will operate together with distributed wind and solar power plants. Massive energy storage enables a wide set of features ranging from improved supply and demand adjustment, increased system reliability and decarbonization of energy intensive sectors including heating services, industry, and transport. Within this framework, green hydrogen outstands as a key solution to unleash the full potential of renewable energy sources to decarbonize energy applications…

Ammonia-based Clean Energy System with Ultra-High Energy Density

Amogy builds a novel carbon-free high energy density system using ammonia (NH3) as a fuel, with the targeted system-level energy densities of >1,000 Wh/kg (gravimetric) and >750 Wh/L (volumetric), respectively.  The solution consists of ammonia storage, a miniaturized fuel processor (or called reformer/reactor) and a fuel cell. With highly efficient catalysts operating at significantly low temperature and heat-integrated hybrid reactor, the innovative energy system is optimized for the mobility applications requiring sustainable and dynamic operations. This new energy system could enable the electrification of heavy ground/sea/air transportations, where current existing and emerging technologies, e.g., Li-ion battery or gaseous hydrogen (H2),…

Next Generation Technology Integration Platform for Low- and Zero-Carbon Ammonia Production and Utilization

RTI International and its partners are developing a Technology Integration Platform (TIP) to demonstrate next-generation technologies for ammonia (NH3) production and utilization in a modular testbed as part of U.S. Department of Energy ARPA-E’s REFUEL+IT program. The objective of this effort will be to demonstrate the use of NH3 for long duration energy storage, as a fuel, and a hydrogen (H2) carrier.  The TIP, which will be housed at the University of Minnesota West Central Research and Outreach Center’s operational hybrid wind and solar test site, will integrate several breakthrough technologies developed in the REFUEL program to demonstrate an advanced…

New materials for cracking catalysts

Among the many challenges for cracking researchers is their choice of material to build their catalysts from. There is hope that cheaper, more readily-available materials will replace the Ruthenium-based catalysts that have dominated the field up to this point. This

Production and utilization of green ammonia: KIER’s current status and future plans

Green ammonia, a carbon-free chemical, has been drawing much attention as a hydrogen carrier and carbon-neutral fuel for trading green hydrogen and building a carbon-neutral society, respectively, because it has higher volumetric hydrogen content and energy density than liquid hydrogen. And the infrastructure for storing and transporting ammonia is already in place. To implement green ammonia into the current energy systems, technologies on low-cost green ammonia production, decomposition, and utilization are essential. This presentation will show the KIER’s current status and perspective on the development of low-cost green ammonia production and utilization.
