More than ever, energy is at the heart of debates.

Beyond economic and environmental considerations, national energy policies, once the realm of a few experts, have become a matter of societal choices.

Today, our world must seek less abundance and a more informed use of energy. In this context, natural gas plays a crucial role, yet unknown to the general public.

Gas in Focus aims at shedding light on the role of natural gas in this transitional period by providing public access to consolidated, enlightening and reliable information.

Thanks to the expertise of its founding members, GRTgaz and Sia Conseil, this natural gas “observatory” positions itself as a leading guide in this sector. It is composed of five information units: Infrastructures, Uses, Environment, Markets and Supply.


Conversion from Gas L to Gas H

In France, there are actually two types of natural gas distributed: gas L and gas H.Gas L is imported from the Netherlands. It is distributed to the north of France.As for gas H, it comes primarily from the northern sea, Russia, and Algeria. It is then distributed to the whole territory. Mainly composed of methane (CH4) those two gases have however different characteristics.Natural gas L characteristics Gases L and H are defined by distinct calorific powers. Thus the power of gas L is lower than gas H’s (around 10kWh per m2 for gas L, and around 11,5 for gas H), because of...
