“…Katsigiannis et al, [12] examined the multi-criteria assessment for the potential of hydrogen production systems through wind energy, gas turbine and photovoltaic system. Sacramento et al, [13] conducted a study on electrolytic hydrogen production for the Ceara state in Brazil. They observed that the energy consumption and the gross internal product per capita of the region would increase by using the renewable resources to produce hydrogen.…”

Generally, wind to power conversion is calculated by assuming the quality of wind as measured with a Weibull probability distribution at wind speed during power generation. We build on this method by modifying the Weibull distributions to reflect the actual range of wind speeds and wind energy density. This was combined with log law that modifies wind speed based on the height from the ground, to derive the wind power potential at windy sites. The study also provides the levelized cost of renewable energy and hydrogen conversion capacity at the proposed sites. The calculated cost ($/kWh) suggests that the commercial viability is not feasible. We have also electrolyzed the wind-generated electricity to measure the production capacity of renewable hydrogen. We found that all the sites considered are commercially viable for hydrogen production from wind-generated electricity.

“…The addition of hydrogen to natural gas has even more advantages in terms of pollutant reduction, thermal efficiency, and combustion stability allowing some combustion systems to operate with lean fuel mixtures. Hydrogen offers high flame speeds, a wide flammability range [1e3], low minimum ignition energy and no emissions of HC or CO 2 [4,5]. It is actually considered as one of the most promising alternative fuels for future engines.…”

a b s t r a c tEffects of hydrogen enrichment and steam addition on laminar burning velocity of methaneeair premixed flame were studied both experimentally and numerically.Measurements were carried out using the slot burner method at 1 bar for fresh gases temperatures of 27 C and 57 C and for variable equivalence ratios going from 0.8 to 1.2.The hydrogen content in the fuel was varied from 0% to 30% in volume and the steam content in the air was varied from 0 to 112 g/kg (0e100% of relative humidity). Numerical calculations were performed using the COSILAB code with the GRI-Mech 3.0 mechanism for one-dimensional premixed flames. The calculations were implemented first at room temperature and pressure and then extended to higher temperatures (up to 917 K) and pressures (up to 50 bar). Measurements of laminar burning velocities of methanee hydrogeneair and methaneeairesteam agree with the GRI-Mech calculations and previous measurements from literature obtained by different methods. Results show that enrichment by hydrogen increases of the laminar burning velocity and the adiabatic flame temperature. The addition of steam to a methaneeair mixture noticeably decreases the burning velocity and the adiabatic flame temperature. Modeling shows that isentropic compression of fresh gases leads to the increase of laminar burning velocity.

“…For example, Farfan et al tested the potential of hydrogen generation by applying a multi-criteria assessment through a gas turbine, a photovoltaic system, and wind energy to find that when energy activity is slow, an integrated heated pump, hydrogen storage systems and a wind turbine can provide a continual supply of energy [16]. Sacramento et al conducted a study in the state of Ceara, Brazil, to evaluate the production of electrolytic hydrogen, where the per capita gross internal product and energy consumption of the region would be increased [17]. Bhattacharyya et al suggested that hydrogen produced by electrolyzed water and renewable wind energy do not produce carbon dioxide or other dangerous gases, and can be used as part of an optimal energy mix to reduce dependency on fossil fuels [18].…”

In this study, we developed a new hybrid mathematical model that combines wind-speed range with the log law to derive the wind energy potential for wind-generated hydrogen production in Pakistan. In addition, we electrolyzed wind-generated power in order to assess the generation capacity of wind-generated renewable hydrogen. The advantage of the Weibull model is that it more accurately reflects power generation potential (i.e., the capacity factor). When applied to selected sites, we have found commercially viable hydrogen production capacity in all locations. All sites considered had the potential to produce an excess amount of wind-generated renewable hydrogen. If the total national capacity of wind-generated was used, Pakistan could conceivably produce 51,917,000.39 kg per day of renewable hydrogen. Based on our results, we suggest that cars and other forms of transport could be fueled with hydrogen to conserve oil and gas resources, which can reduce the energy shortfall and contribute to the fight against climate change and global warming. Also, hydrogen could be used to supplement urban energy needs (e.g., for Sindh province Pakistan), again reducing energy shortage effects and supporting green city programs.
