NW Natural injects hydrogen into gas lines without informing customers or regulators. Hydrogen is risky & distracts from more effective, cost-efficient decarbonization approaches, esp. electrification. oregoncapitalchronicle.com/2024/08/02/e... #hydrogen #embrittlement #NaturalGas #Oregon

The sheet has significantly yellowed, the crease at its centre has developed into a split and numerous losses have occurred at the margins.
The yellowing of paper is largely caused by the oxidation of lignin, an organic substance found in wood which provides structural support and rigidity. The Industrial Revolution made paper more accessible and affordable owing to mass production but with this came greater demand. To meet this, the use of rags as the primary material in paper making was replaced by wood pulp, a readily available but less durable alternative.
Exposure to excessive heat, light and low humidity causes the lignin in wood pulp paper to degrade and become acidic, and this weakens the cellulose fibres. Whilst the resulting embrittlement is irreversible, it can be somewhat managed through deacidification treatments and careful storage.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:o3vof7rjobhzoxvub42zxtot/bafkreig6zadbdewmkyczv56ehlbev6lktreryd3iktcepkw2o25xshb7e4)

E is for… #Embrittlement
Excessive exposure to heat, light and low humidity can cause a substrate or medium to lose its flexibility, resulting in splitting, crumbling and loss. Commonly observed in paper made from wood pulp owing to its high lignin content.
