Currently the efficiency for hydrogen production by water electrolysis of electricity amounts to 75 to 85% [19] with potential up to 93% until 2030. [25] Efficiency for methanol synthesis of hydrogen and carbon dioxide currently is 79 to 80%. [19] Thus the efficiency for production of methanol from electricity and carbon dioxide is about 59 to 78%.
The fuel cartridge stores the methanol fuel. Depending on the system design either 100% methanol (IMPCA industrial standard) or a mixture of methanol with up to 40 vol% water is usually used as fuel for the RMFC system. 100% methanol results in lower fuel consumption than water-methanol mixture (Premix) but goes along with higher fuel cell system complexity for condensing of cathode moisture.
The conversion efficiency is essentially 100% from minimum detectable levels up to a flow of CO or CO 2 at the detector of about 5 × 10 −5 g/s. These represent a detection limit of about 200 ppb and a maximum concentration of about 10% in a 0.5mL sample. Both values are dependent upon peak width.
2 pollutant concentration monitor and a volumetric flow monitor. For NO x, both a NO x pollutant concentration monitor and a diluent gas monitor are used to determine the emissions rate in weight per volume or weight per heat value (for example lbs/million Btu, lbs/ft 3, kg/kWh or kg/m 3). Opacity measurements are sometimes required, depending ...

A 1965 report suggested synthesizing methanol from carbon dioxide in air using nuclear power for a mobile fuel depot. [62] Shipboard production of synthetic fuel using nuclear power was studied in 1977 and 1995. [63] [64] [65] A 1984 report studied the recovery of carbon dioxide from fossil fuel plants. [66]
providing water along with methanol would make the fuel supply more cumbersome, so water has to be recycled in a loop; CO 2 has to be removed from the solution flow exiting the fuel cell; water in the anodic loop is slowly consumed by reaction and drag; it is necessary to recover water from the cathodic side to maintain steady operation.
The annotation, d a°C/b°C, indicates density of solution at temperature a divided by density of pure water at temperature b known as specific gravity. When temperature b is 4 °C, density of water is 0.999972 g/mL.
