It has an energy density of 1.77 kWh/L and 1.22 g/cm^3, or 1.45 kWh/kg (http://pubs.acs.org/doi/pdf/10.1021/acsenergylett.6b00574 http://pubs.acs.org/doi/pdf/10.1021/acsenergylett.6b00574). Compare to gasoline at 12.9 kWh/kg (https://en.wikipedia.org/wiki/Energy_density https://en.wikipedia.org/wiki/Energy_density) and li-ion batteries at 0.1-0.3 kWh/kg (https://en.wikipedia.org/wiki/Lithium-ion_battery https://en.wikipedia.org/wiki/Lithium-ion_battery).
- digi_owl 9y agoHonestly nothing can beat gasoline up front. but here we have something that can match li-ion, but that can be refueled as easily as one refuel a gasoline car. Can be stored for long periods on simple containers. And can be produced from atmospheric gasses.
- jws 9y agoInteresting implications for fixed location energy storage. A palette sized tote of water is about 1000 liters, so 1.45MWh/tote. That is roughly a month of US household electrical consumption. I'm not finding numbers for efficiency of creating the formic acid, and for the catalyst I find notes that the good ones use expensive elements. So I guess when my new lead acid battery bank wears out in 8 years I won't be installing a formic acid system.
