It is usually found in combination with other elements, such as oxygen in water or carbon in methane. This makes it difficult and expensive to extract hydrogen from its natural sources.<\/p>\n<p>The main chemical property of hydrogen that makes it difficult to produce is its high reactivity. Hydrogen is highly flammable and can easily react with other elements to form new compounds.

This energy can come from fossil fuels, nuclear power, or renewable sources such as solar and wind power. However, the cost of producing hydrogen from these sources is still high.<\/p>\n<p>Despite the challenges, hydrogen production is an important goal for the future.
