Advanced Power Controls for Hydrogen Hybrid Microgrids (HHM) with Thermal Storage

Lank R.J., Tucker D., Resilient Power Works, LLC; National Energy Technology Laboratory, US

The Hydrogen Hybrid Microgrid (HHM) is a resilient and scalable power generating plant comprised of a (NG) turbine, a compressor, a NG reformer, a Solid Oxide Electrolizer Cell (SOEC) and a Solid Oxide Fuel Cell [...]

Recent Advances in Electrospun Fiber Mat Electrode MEAs for Hydrogen/Air Fuel Cells

Waldrop K., Fan X., Kang N., Wycisk R., Gumeci C., Dale N., Pintauro P.N., Vanderbilt University, US

The hydrogen/air proton-exchange membrane fuel cell is a promising candidate for automotive power plants, but Pt/C catalyst electrode cost and durability are still issues that require further study. Recently, there has been considerable work on [...]

Integrating a Gas Turbine System and a Solid Oxide Steam Electrolyzer for Hydrogen Production

Hosseini S.E., Arkansas Tech University, US

In this paper, the performance of a gas turbine (GT) system coupled with a flameless boiler for steam generation for hydrogen production in a solid oxide steam electrolyzer (SOSE), is evaluated. In this design, the [...]

Low-Pressure Electrolytic Ammonia Production for Ammonia-Based Energy Storage

Thakare J., Masud J., Aulich T., University of North Dakota, US

The Energy & Environmental Research Center (EERC) is developing a low-pressure 1-step electrolytic ammonia (1-SEA) process that would enable ammonia-based energy storage technology (NH3-BEST) in combination with a direct ammonia fuel cell to enable electricity [...]

Novel Graphene Supercapacitor Structure Design for UAV Power Storage

Kim J., Rivas A., Wu S., Martinez V., Terroza K., Karthikeyan D., Contreras F., Castro J., Botello E., Pandit R., Dobbs S., Yu Z., California State Polytechnic University, Pomona, US

Supercapacitors are getting significant attention in recent years due to their quick charge/discharge capabilities, long cycle lives and are environmentally friendly. Supercapacitors can provide necessary power in short bursts. Aiming to reduce the weight and [...]

Development of a Phase Change Energy Storage Module with High Recovery Rate for Power Generation Applications

Belaed M., Rahman M.M., Wichita State University, US

Using phase change materials (PCMs) as a storage medium has gained great attention because of its low cost and desirable size. But poor thermal conductivity makes the use of PCM challenging as this dramatically increases [...]

Production of Supercapacitor Carbon Electrodes from Corn-stover Via Facile Thermal Activation

Shell K.M., Maddipudi B.K., Amar V., Thakkar A., Shende R.V., Kumar S., Gupta R.B., Virginia Commonwealth University, US

Use of biomass is an emerging and promising alternative to produce carbon electrodes for supercapacitors. Lignin-rich unhydrolyzed solids (UHS) obtained from alkaline pretreatment and enzymatic hydrolysis of corn stover were valorized into biochar via hydrothermally [...]

Storage Synthesis of Power Systems via Dynamic Meta-control Schema

Kohn W., Zabinsky Z.B., Crowdpoint Technologies, US

Electric vehicles are usually driven by induction or DC motors. They are provided with dynamic braking and acceleration: during braking, the motor becomes a generator driven by the wheels; and during acceleration, the motor requires [...]

Hybrid Photovoltaic/Thermal Solar Plus Storage Cogeneration Systems

Bond A., Anderson M.G., Beachnau B., Icarus RT, Inc., US

Current PV technology is inefficient, converting only about 21% of solar energy into usable power at the ideal temperature of 25 °C. Panels often reach temperatures of 65– 75 °C, significantly reducing production. Still, commercial [...]

Fabrication and Opto-Electronic Modeling of Down-Shifting Enhanced Photovoltaics

Montes-Bojorquez J.R., Villa-Bracamonte M.F., Ayon A.A., University of Texas at San Antonio, US

We report the fabrication and spectroscopic ellipsometry characterization of layer-by-layer assembled quantum dot multilayered films and their influence in the power conversion efficiency of silicon solar cells. The experimental performance of the resulting structure that [...]
