This interconversion between hydrogen and electricity could be a significant component of how a future hydrogen economy would operate since there would likely be synergies between storing electricity and producing alternative energy carriers and transportation fuels. 2.2.2. Convergence and competition for resources.
Ammonia is generally more economical than hydrogen as a single method of energy storage. Additionally, systems which use both hydrogen and ammonia outperform those which use only one storage option and have LCOE between $0.17/kWh and $0.28/kWh, including full investment in renewable generation infrastructure.",
A key takeaway from this paper is the importance of a holistic approach to addressing the challenges of hydrogen energy storage. Technological advancements
Interest in hydrogen energy can be traced back to the 1800 century, but it got a keen interest in 1970 due to the severe oil crises [4], [5], [6]. Interestingly, the development of hydrogen energy technologies started in 1980, because of its abundant use in balloon flights and rockets [7]. The hydrogen economy is an infra-structure
Whereas a proportional relationship exists between solar radiation and the amount of power generation, wind power generation does not exhibit a proportional relationship between wind speed and the amount of power generation. Hydrogen energy, economy, and storage: review and recommendation. Int J Hydrogen Energy,
High energy demand to liquefy hydrogen and keep it in cryogenic conditions result in an energy loss of up to 40% especially when the temperature difference between the environment and the stored hydrogen is so extreme (Table 12.1) [21]. Furthermore, the additional cost is incurred since the storage tank must be well insulated

Yilmaz et al. [81] studied the importance of this parameter and deduced that a 0.253 g of hydrogen is produced for each kilogram of geothermal water. This was calculated at geothermal resource temperature and flow rate of 160 °C and 100 kg/s, respectively, such that the rate of hydrogen production was 0.0253 kg/s.
For instance, 1 kg of hydrogen produced by renewable energy costs upto ∼$23 (varied according to the technical advances in renewable energy and hydrogen production technologies), whereas hydrogen produced by fossil fuel costs below $2 (Mohideen et al., 2023; United Nations Economic, 2022).
Hydrogen has emerged as a promising energy source for a cleaner and more sustainable future due to its clean-burning nature, versatility, and high energy content.
