Hydrogen generation in microbial reverse-electrodialysis electrolysis cells using a heat-regenerated salt solution.
Hydrogen gas can be electrochemically produced in microbial reverse-electrodialysis electrolysis cells (MRECs) using current derived from organic matter and salinity-gradient energy such as river water and seawater solutions. Here, it is shown that ammonium bicarbonate salts, which can be regenerated using low-temperature waste heat, can also produce sufficient voltage for hydrogen gas generati...
متن کاملWaste Heat to Power Systems
Waste heat to power (WHP) is the process of capturing heat discarded by an existing industrial process and using that heat to generate power (see Figure 1). Energyintensive industrial processes—such as those occurring at refineries, steel mills, glass furnaces, and cement kilns—all release hot exhaust gases and waste streams that can be harnessed with wellestablished technologies to generate el...
متن کاملHydrogen production from inexhaustible supplies of fresh and salt water using microbial reverse-electrodialysis electrolysis cells.
There is a tremendous source of entropic energy available from the salinity difference between river water and seawater, but this energy has yet to be efficiently captured and stored. Here we demonstrate that H(2) can be produced in a single process by capturing the salinity driven energy along with organic matter degradation using exoelectrogenic bacteria. Only five pairs of seawater and river...
متن کاملTime to turn up the HEAT?
In a lifetime of observing and participating in politics, the world wide campaign by the international green movement (aided by the power-seeking UN bureaucracy) to monitor, control and tax every food, energy and transport business in the world is the most dangerous development I have ever seen. It has the potential to blight the lives and investments of the majority of Australians who are unab...
متن کاملMicrobial reverse electrodialysis cells for synergistically enhanced power production.
A new type of bioelectrochemical system for producing electrical power, called a microbial reverse-electrodialysis cell (MRC), was developed to increase voltages and power densities compared to those generated individually by microbial fuel cells (MFCs) or reverse electrodialysis (RED) systems. In RED systems, electrode overpotentials create significant energy losses due to thermodynamically un...
