[Biogas and biomethane](https://www.materialinsights.org/energy/biomethane/) (chemical) and [Gas pipelines and city gas](https://www.materialinsights.org/energy/e_gas_pipelines/) (energy): 2 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · 20% of flow · Biogas and biomethane → Gas pipelines and city gas*

Upgraded biomethane is injected into the natural gas grid.

- **20%** of Biogas and biomethane's energy goes this way

### 2. Price link: grid injection

*Cost and price · Strong · Both ways*

Biomethane reaches users through gas grids, and delivered gas prices include network costs. The delivered gas index correlates at 0.15 for monthly moves but 0.79 for yearly moves, as utility tariffs adjust slowly to Henry Hub.

- **0.15** monthly change correlation
- **0.79** 12-month change correlation
- **0.90** fitted elasticity
