Energy systems are evolving rapidly around the world, driven mainly by CO2-e reduction targets. This has led to opportunities for integrated low carbon electricity-and-fuel systems founded on large scale “Power-to-Hydrogen, Hydrogen-to-X” (PtH-HtX). Power-to-Hydrogen (PtH) refers to large scale electrolysis. Hydrogen-to-X (HtX) refers to a range of high value products and services. If these pathways...
A Fuel Cell Oxygen Tree is a combination of Artificial Oxygen Tree (AOT) and Fuel Cell (FC). AOT is use to obtain Hydrogen (for fuel) and Oxygen (to be emitted in the air) by performing sea water electrolysis; with the help of PV (Photovoltaic) panels to generate electricity from solar energy installed on the top of the trees. FC is a device which perform reverse electrolysis by using hydrogen as...
The world is beginning to embrace a transition from fossil fuel-based energy production and distribution methods to renewable energy-based methods. This is becoming more and more evident as governments around the world enact standards and regulations that require energy portfolios to be composed of ever-growing portions of renewable production. However, as this transition develops many questions and...
Currently, fossil fuels as main energy source to fulfill world's energy demand is depleting fast. Their waste products are also causing global environment problems. One of the solutions is to replace the existing fossil fuel energy systems by the hydrogen energy system. This paper presents a small electrical energy generator based on solar-hydrogen fuel cell. The system comprises solar modules, electrolyzer,...
A dynamic compartmental model based on first principles is developed for a tubular solid oxide fuel cell system. The model accounts for diffusion processes, inherent impedance, transport (heat and mass transfer) processes, electrochemical processes, anode and cathode activation polarizations, and internal reforming/shifting reactions, among others. Dynamic outlet voltage, current and fuel-cell-tube...
Fuel cells are one of the key enabling technologies for future hydrogen economy. For the last 20 years applications for the fuel cells are mostly replacing internal combustions engines, and providing power in stationary and portable power applications. But the history of the fuel cells is more than the last 20 years; actually it has more than 150 years! It is the purpose of this paper to present the...
A technique for the practical utilization of solar energy on a continuous basis to provide bulk power is described. The output of solar energy converters is used to produce hydrogen by pressure electrolysis of water. The energy stored in the hydrogen can be efficiently transformed into electrical energy by the use of hydrogen-oxygen fuel cells.
