Renewable and Alternative Energy Resources. Description: Hydrogen energy is a hot topic in the goal to develop a greener and more efficient power technology
Hydrogen is an ideal fuel in terms of smog reduction when used electrochemically in a fuel cell, rather than combusted. Hydrogen in a fuel cell produces zero harmful emissions. Oxides of nitrogen are completely eliminated due to the low operating temperature (175 oF; 80 oC) of the cells.

Hydrogen can be produced from a number of diverse domestic resources, and. fuel cells can generate electricity efficiently from a number of fuels, including biogas, natural gas, propane, methanol
some hydrogen-containing primary sources such as water or carbohydrate. The current estimates indicate that around 48%, 30%, and 18% of hydrogen is derived from natural gas, naphtha reforming, and coal gasification, respectively [27]. Regrettably, most conventional methods for producing hydrogen from fossil fuels cause

Electricity prices: £30/MWh, £46/MWh, £53/MWh. Fuel accounts for the bulk of the costs of hydrogen in these estimates. The central gas cost of £25/MWhH2 accounts for 66% of the estimated cost of the hydrogen. The central estimate of electricity cost of £63/MWhH2 is 85% of the total cost of the resulting hydrogen.
Hydrogen contains 33.33 kWh energy per kilo, compared to 12 kWh of petrol and diesel [39]. However, storing the same amount of hydrogen requires a larger volume.
