hydrogen may not be advantageous as a fuel because.......?

It is not plentiful nor naturally found as Hydrogen.

It is a secondary source of energy

Hydrogen may not be advantageous as a fuel for several reasons:

1. Production and Infrastructure: Producing hydrogen often requires energy-intensive processes such as steam reforming or electrolysis. Additionally, there is a lack of widespread hydrogen infrastructure, including storage, transportation, and fueling stations, which makes it less convenient and costly to implement on a large scale.

2. Storage: Hydrogen has a low energy density compared to fossil fuels, which means it needs to be stored at very high pressures or extremely low temperatures. This requirement makes it challenging and expensive to store and transport hydrogen safely and efficiently.

3. Safety Concerns: Hydrogen is highly flammable and can ignite easily, even at low concentrations. This poses a safety risk, especially in confined spaces or if leaks occur in the storage or transportation systems.

4. Efficiency: Converting hydrogen into usable energy often involves the use of fuel cells, which have an efficiency lower than that of conventional internal combustion engines. The energy loss during hydrogen production, storage, and conversion reduces the overall efficiency of the system.

5. Environmental Impact: Although hydrogen is a clean-burning fuel that only produces water vapor as a byproduct, the production of hydrogen using current methods often relies on fossil fuels, releasing greenhouse gases into the atmosphere. Additionally, the extraction of hydrogen from water requires a substantial amount of electricity, which may also come from fossil fuel sources.

To evaluate whether hydrogen is advantageous as a fuel, one can consider the factors mentioned above and assess the feasibility, cost-effectiveness, safety, and environmental impact of using hydrogen as an energy source.
