But its energy density by volume is nearly double that of liquid hydrogen—its primary competitor as a green alternative fuel—and it is easier to ship and distribute. "You can store it, ship it, burn it, and convert it back into hydrogen and nitrogen," says Tim Hughes, an energy storage researcher with manufacturing giant Siemens in Oxford, U.K.

Energy storage – ammonia is easily stored in bulk as a liquid at modest pressures (10-15 bar) or refrigerated to -33 C. This makes it an ideal chemical store for renewable energy. There is an existing distribution network, in which ammonia is stored in large refrigerated tanks and transported around the world by pipes, road tankers and ships.

The former calls for effective on-site carbon dioxide (CO 2) capture or upgrading to valuable chemicals 3,4,5, and the latter relies on flexible energy storage to level the power load 2,6.
Therefore, the conversion of CO2 into fuels is a promising and convenient way to minimize global warming caused by the growing concentration of CO2 in the atmosphere and meet the world''s high energy demand. The conversion of CO 2 into fuels is achieved via various chemical conversion and biological conversion methods.
All three fuel pathways are evaluated on unit basis (1 mol/s) synthesis to determine the power-to-fuel, fuel-to-power and power-fuel-power efficiencies. In the case of power-to-fuel, the capacities of the designed unit mass synthesis systems are 1.38 ton/day of methane, 3.97 ton/day of DME and 2.76 ton/day of methanol.
