Submissions will be evaluated using **Mean Squared Error (MSE)**, a common metric for regression tasks. This measures the average squared difference between the predicted methane storage capacities (`highUptake_mol`) and the actual values in the test set. Lower values of MSE indicate better model performance.

## Submission File

Your submission must include predictions for the `highUptake_mol` variable for each ID in the test set. The file should contain a header and have the following format:

```csv
id,highUptake_mol
1,10.234
2,15.678
3,9.876
...
```

Please ensure that the `id` column in the submission corresponds to the ID from the test dataset, and that the predictions in the `highUptake_mol` column are in the same order. Submissions without the correct format or missing columns will not be accepted.
