5.3 Introduction

In the wider sense Gas is prime energy as it is found naturally. But not all gas is prime energy - see below.

Like crude oil gas needs to be processed before it is pumped through pipelines to our buildings (or delivered by bottle or into tanks).

We can distinguish between:

• Fossil natural gas
• Town gas (not prime energy)
• Biogas (prime energy - but not prime energy if produced in reactors)
• Crystallized natural gas - Hydrates (not yet recoverable)

Natural gas is today the main form of gas used. The production of Town Gas generates a high degree of pollution and is not an effective process.

Bio-gas is an interesting alternative to pumping gas around and towards securing energy supplies. But its production is minuscule at present considering the total demand for gas. It also produces pollutants and contributes to global warming. So, the term "bio"is not giving it a full green light in todays global warming debate.
