Prometheus Fuels is an American energy startup developing tools to filter atmospheric CO 2 using water, electricity, and nanotube membranes to produce commercially viable fuels. When powered by renewable electricity sources, e-fuels produced by such direct air capture methods do not contribute further emissions, making them carbon neutral . [ 1 ]
Robert L. McGinnis is an American scientist, [1] technology entrepreneur, and inventor who has founded a number of technology companies including Prometheus Fuels, [2] Mattershift [3] and Oasys Water.
The specific weight (also known as the unit weight) is the weight per unit volume of a material Stack Stack, to deliver the desired amount of energy, the fuel cells can be combined in series and parallel circuits, where series yield higher voltage, and parallel allows a stronger current to be drawn. Such a design is called a fuel cell stack.
An ideal electrolysis unit operating at a temperature of 25 °C having liquid water as the input and gaseous hydrogen and gaseous oxygen as products would require a theoretical minimum input of electrical energy of 237.129 kJ (0.06587 kWh) per gram mol (18.0154 gram) of water consumed and would require 48.701 kJ (0.01353 kWh) per gram mol of ...
A fuel control unit attempts to solve those problems by acting as an intermediary between the operator's controls and the fuel valve. The operator has a power lever which only controls the engine's potential, not the actual fuel flow. The fuel control unit acts as a computer to determine the amount of fuel needed to deliver the power requested ...
The design uses standard full-length PWR fuel enriched to 4.95% and closed-cycle air cooling. [43] Due to its reliance on air cooling systems, the PWR-20 does not need to be sited near a water source and is tailored to serve dispersed energy users. [44] Last Energy can deliver more than one unit to scale output to the customer's needs. [43]
In areas with a shortage of base-load and load following power plant capacity or with low fuel costs, a gas turbine powerplant may regularly operate most hours of the day. A large single-cycle gas turbine typically produces 100 to 400 megawatts of electric power and has 35–40% thermodynamic efficiency. [7]
A typical fluid catalytic cracking unit in a petroleum refinery. Fluid catalytic cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, alkene gases, and other petroleum products.
