What is the term used to refer “Transportation and storage of energy in the form of liquid or gaseous dihydrogen

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term that refers to the transportation and storage of energy in the form of liquid or gaseous dihydrogen.

2. **Identifying the Key Concept**: The key concept here is the method of storing and transporting hydrogen. Hydrogen can exist in different states, primarily as a gas or a liquid.

3. **Defining the Term**: The term that encapsulates the transportation and storage of hydrogen is known as the "hydrogen economy." This concept involves using hydrogen as a fuel source and addressing the challenges related to its storage and transportation.

4. **Explaining the Process**: In the hydrogen economy, hydrogen is often converted into a liquid state. This is achieved by cooling hydrogen gas under high pressure, which allows it to be stored more compactly and transported more easily.

5. **Storage Methods**: Liquid hydrogen can be stored in cryogenic tanks, which are designed to maintain the low temperatures necessary to keep hydrogen in its liquid state. This method ensures safe and efficient storage and transport.

6. **Conclusion**: Therefore, the term used to refer to the transportation and storage of energy in the form of liquid or gaseous dihydrogen is the "hydrogen economy."
