Abstract

MgH2 + 2H2O = Mg(OH)2  + 2 H2 + 278 KJ;

278 KJ * 0.33 (energy efficiency) = 90 KJ electricioty

2 H2 =H2-air fuel cell = 400 KJ electricity,

and totally, 90 + 400 = 490 KJ electricity = 5235 kWh /M T of MgH2.

 

Recycling

Mg(OH)2 = MgO + H2O -  38 KJ,

MgO + CO = Mg + CO2 = 318KJ;

And novel catalytic conversion CO2 in CO [1] = - 283 KJ;

Mg +  H2 = MgH2 = + 75 KJ. 

CO + H20 = H2 + CO2 –  3 KJ.

And totally = - 850 KJ. =  9100 kWh/ MT of  MgH2 .

So the system energy efficiency is 5235 / 9100 = 58%
