Summarize the strengths and weaknesses of hydrogen gas as an alternative energy.
Strengths:
1. Hydrogen gas is a clean and renewable energy source that produces no greenhouse gases or pollutants when used in fuel cells.
2. It can be produced from a variety of sources, including water, natural gas, and biomass.
3. Hydrogen has a high energy density, making it an efficient energy storage option.
4. It can be used in a wide range of applications, including transportation, electricity generation, and heating.
Weaknesses:
1. Production of hydrogen gas can be costly and energy-intensive, depending on the method used.
2. Infrastructure for producing, storing, and distributing hydrogen is limited and expensive to build.
3. Hydrogen gas is highly flammable and requires special safety precautions when used and stored.
4. Fuel cells and hydrogen technology are still in the early stages of development and not yet widely adopted.
