The Future of Hydrogen – Analysis
The growing trend of energy demand has imposed a significant strain on the environment. Since sustainable development is a dominating agenda or top goal for virtually every country, there is an urgent need to discover clean and sustainable alternatives to existing non-renewable resources (e.g., fossil fuels). As a clean, safe, and efficient energy …
Hydrogen Production and Infrastructure Projects Database
Hydrogen is increasingly being recognized as a promising renewable energy carrier that can help to address the intermittency issues associated with renewable energy sources due to its ability to store large amounts of energy for a long time [[5], [6], [7]].This process of converting excess renewable electricity into hydrogen for storage …
As it can be seen from Table 2, the AB 5-type materials with different Ce/La ratios and AB 2-type ones with different Zr/Ti ratios (both from the A side) allow to develop on their basis various hydrogen storage and compression systems operating in various ranges of temperatures and H 2 pressures. pressures.
As a fuel, hydrogen and ethanol are more alternative to gasoline for the easy spark-ignition, the comparison of fuel properties among hydrogen, ethanol and gasoline is listed in Table 2 (the ethanol there is pure ethanol rather than bioethanol since the latter''s property will be different due to different feedstocks and production …

Latin America1 is one of the world''s leading regions for renewable energy use today and one that can play a major role in the international push for low-carbon hydrogen, a crucial element of a global net-zero emissions future. In this context, low-carbon hydrogen has ...
The gravimetric density of hydrogen energy is generally about seven times higher than the density of fossil fuels [7]. Hydrogen energy will undoubtedly be one of the main energy sources of the future, but there are some issues that need improvement. After generating hydrogen energy, problems such as transportation and storage arise [8].

As it can be seen, most commonly used "low-temperature" intermetallic hydrides are characterised by weight hydrogen storage density between 1.5 and 1.9 wt%, while the use of BCC solid solution alloys on the basis of Ti–Cr–V system allows to reach H storage capacity up to ~2.5 wt%; the latter materials, as well as some AB 2-type …
The classification mainly bases on primary energy sources used to generate hydrogen and production technologies [1, 20]. Green hydrogen is considered to be clean, which relies primarily on renewable energy to produce. Grey hydrogen from fossil fuels can place a significant burden on the environment during its production.
