Excerpt via Term Paper:

Carbon monoxide gas [CO (g)] is a side product of this reaction which defeats the purpose of alternative gas sources to remove production of greenhouse gases. Following the first and second laws of thermodynamics, this process results in a severe energy loss. The first legislation of thermodynamics says that the energy outcome from any kind of process aren’t exceed the energy input, and the second legislation focusing in part on decay states that each process decays energy.

The availability of the methanol from gas results in a primary 32% to 44% net energy reduction, then the steam treatment procedure to procure the hydrogen ends in a further 35% energy reduction.

Several procedures are being explored to derive hydrogen from normal water, as a great inexhaustible resource. However , this reaction, 2H2O + at the = 2H2(g) + O2(g), requires a substantial energy investment per product of normal water (286kJ every mole).

This kind of energy purchase is once again required simply by both the initial and second laws of thermodynamics and renders the electrolysis of water unprofitable in terms of strength return based upon the energy invested.

Any successful hydrogen economy would require an system that could make use of zero-carbon capacity to electrolyze water into hydrogen, convey this highly dissipate gas long distances, and pump this at high pressure into a car or in our large fuel cells in our homes. Next, the hydrogen would need to be changed back into electricity to drive an electric motor or electric programs. The cumulative process of electrolysis, transportation, growing and fuel-cell conversion might render simply 20 to 25% in the original electrical power as functional.

However , you will find other options. Within a plug-in hybrid, the process of electrical energy transmission, recharging an onboard battery might leave 75 to many of these of the unique electricity to drive the electric motor. Thus a plug-in must be able to travel three to four times further on a kilowatt-hour of alternative electricity compared to a hydrogen fuel cell may.

Because of the second law of thermodynamics, hydrogen fuel cells will always include a limited energy return, and depending upon the method will contribute to green house gas emissions. Further more, a hydrogen-based economy can require considerable development and land employ which could end up being cost prohibitive. As a result, it is not a feasible replacement to non-renewable fuels as a power source.
