The future energy: Hydrogen versus electricity

Hydrogen production using an anaerobic baffled reactor – Mass balances for pathway analysis and gas composition profiles

“…The lower part of Table 4 assumes the production of lactic acid via the bifidum pathway (7), giving 147 l/d of H 2 produced via reaction (1,2). Summing up equation (8) Table 5.…”

“…Today, more than 5$10 9 kg hydrogen is produced worldwide, mainly by the steam reforming of methane [1]. Towards a sustainable future and a 100% renewable energy system, new processes for hydrogen production have to be developed to become compatible [2,3]. Besides the well known production by electrolysis, the biological conversion of biomass seems to offer promising options [4e7].…”

THERMO economic analysis OF PV and hydrogen gas turbine hybrid power plant of 100 MW power output

“…Life Cycle Cost (LCC) analysis was conducted and the PV LCC generation cost for all the system was 0.172 $/kWh. Marchenko and Solomin [18] compared the processes of hydrogen and electricity production, conversion and storage in terms of energy and economic expenditure for each stage of these technologies. The assessment showed that the electricity economy proves more preferable in the case of short-term energy storage, whereas the use of hydrogen is more beneficial in the case of long-term storage.…”

Geothermal energy use in hydrogen production: A review

“…18 Beside greenhouse gas emissions, further disastrous emissions such as sulfur oxides, nitrogen oxides, and particulates causing smog 19 can also be eradicated to mitigate global warming. 21 In addition, energy security can be achieved by utilizing domestic, locally available, dependable, and viable energy and material sources for hydrogen production, distribution, storage, and end-use. 21 In addition, energy security can be achieved by utilizing domestic, locally available, dependable, and viable energy and material sources for hydrogen production, distribution, storage, and end-use.…”
