Hydrogen is a potential alternative to traditional jet fuel, but it's not yet used on commercial flights.

Hydrogen is a clean and renewable source of fuel.

Hydrogen is a non-toxic, non-flammable gas that can be produced from many different sources including water, steam, solar energy, and even animal waste (eek!). It's also considered to be the most abundant element in the universe by far—around 99.3% of all matter on Earth is hydrogen!

This makes it an excellent choice for aviation purposes because it doesn't cause any pollution at all during its production process or combustion within your engine. In fact, hydrogen burns with zero carbon emissions so there's no need to worry about CO2 emissions being released into the atmosphere when you fly with this product!

It is a more efficient fuel than standard aviation fuel.

The first reason to use hydrogen as a fuel is that it is a more efficient fuel than standard aviation fuel. In fact, hydrogen is the most efficient of all known fuels in terms of its energy density, which means that it takes less space to carry the same amount of energy.

A second benefit of using hydrogen as aviation fuel over kerosene or Jet-A is that it can be stored at room temperature and pressure for long periods without loss or damage due to freezing during storage or exposure to extreme temperatures during flight operations.

It is a less expensive fuel than standard aviation fuel.

The main benefit of using hydrogen as aviation fuel is that it is less expensive than standard aviation fuel. This means that your flight will cost less, and you can spend more time enjoying the experience instead of worrying about how much money your plane has burned up.

However, there are some drawbacks to using hydrogen as aviation fuel:

It's more expensive than kerosene or Jet-A (kerosene is a type of petroleum product used in jet engines).
You'll have to store it somewhere safe until needed by someone else who knows how to use it safely--like at an airport or other location where they can refuel aircraft regularly (that way they won't have any issues with theft).
It is safer than other jet fuels, such as kerosene or Jet-A.

Hydrogen is a safer fuel than kerosene or Jet-A. That’s right: hydrogen is more environmentally friendly and better for the environment than other jet fuels, such as Kerosene (kerosene) or Jet-A (Jet A).

Why? Because it burns cleaner. And because it's so clean, you don't need to worry about any nasty particulates in your cabin as you do with other types of aviation fuels like Kerosene or Jet-A!
