We introduce a paradigm-"hydricity"-that involves the coproduction of hydrogen and electricity from solar thermal energy and their judicious use to enable a sustainable economy. We identify and implement synergistic integrations while improving each of the two individual processes. When the proposed integrated process is operated in a standalone, solely power production mode, the resulting sola...

Objectives • Develop the concept of a solid oxide fuel-fed electrolysis cell (SOFEC) for hydrogen production. • Identify and develop SOFEC cathode materials that are electrocatalytically and chemically stable in both reducing and oxidizing atmospheres. • Develop a novel concept of a composite/hybrid planar SOFEC-solid oxide fuel cell (SOFC) stack to co-generate hydrogen and electricity. • Demon...

This paper proposes a methodology to estimate the maximum revenue that can be generated by a company that operates a high-capacity storage device to buy or sell electricity on the day-ahead electricity market. The methodology exploits the Dynamic Programming (DP) principle and is specified for hydrogen-based storage devices that use electrolysis to produce hydrogen and fuel cells to generate el...

In this research, solar-drived integrated Hydrogen production (HP) using high-temperature steam electrolysis (HTSE) is thermodynamically evaluated. This system includes an organic Rankine cycle (ORC), Rankine cycle, Brayton cycle, solar tower, and High Temperature Steam Electrolysis (HTSE). Solar energy supplies thermal energy. This heat source is applied for generating power. This energy is us...

The deployment of wind energy is constrained by wind uncontrollability, which poses operational problems on the electricity supply system at high penetration levels, lessening the value of wind-generated electricity to a significant extent. This paper studies the viability of hydrogen production via electrolysis using wind power that cannot be easily accommodated on the system. The potential be...

Hydrogen and electricity produced from coal will represent a significant share in the energy mix within the foreseeable future. Various novel processes are developed or currently under development for hydrogen and electricity production from coal derived syngas. The commercial coal to hydrogen and coal to electricity processes include the coal gasification-water gas shift process and integrated...

H as this happened to you? You have a layover between flights, would like to use your computer and cell phone, but both sets of batteries are drained and the nearby electrical outlets are being used. What if you could instead recharge your electronic devices with a little sugar from the nearby coffee stand? With help from electricity-producing microorganisms, known as electricigens, some day yo...

Directed Technologies, Inc. has completed three analysis projects for the hydrogen program office during the past year: a detailed mass production cost estimate for stationary proton exchange membrane (PEM) fuel cell systems, an assessment of the costs of producing electricity from stationary fuel cells for buildings with hydrogen and heat cogeneration, and a preliminary assessment of the use o...
