3/3 This CA NIMBY group bases their fears of a hydrogen test in natural gas piping on lower efficiency. Paper IGNORES need to meet peak winter heating demands-CA has 12 underground natgas storage fields. How many batteries will be needed to supply new heat pumps!

2/3 This CA NIMBY group bases their fears of a hydrogen test in natural gas piping on ONE paper, which focuses on efficiency. Paper IGNORES need to meet peak winter SEASONAL demands-hydrogen is far cheaper vs the batteries & electric grid upgrades to supply new heat pumps!

Please read at least some of the hydrogen literature before you make such bot-like pronouncements.
In addition to my hydrogen home vehicle refueling project (below), there are companies making full-home energy storage systems, so you can live off -grid!!

New York's largest battery energy storage system #BESS project (Swiftsure, 650MW on Staten Island) has been canceled.
IMO root cause of failure: $300MM project was too big for Fullmark Energy ($600MM in total solar assets). Delays were starting back in 2022!⬇️

Congrats Aurora Hydrogen on your #NGIFAccelerator microwave methane pyrolysis pilot tests, producing lower-emission turquoise hydrogen & solid carbon.↙️
If you're hiring, look to Monolith Materials, who has recently idled their USA FOAK commercial microwave turquoise #H2 plant.↘️

Got my first battery-lover & Power-to-X hater Bsky block today - he couldn’t handle facts like this:
Replacing the energy of a Boeing 747-300 with a battery would require one weighing 5.8 million pounds — nearly seven times the weight of the fully-fueled plane. Isn’t it the same for shipping?

Here's a pair of reading glasses: 👓
The article is actually about eDiesel, not ePetrol (headline is wrong), as well as eSAF (top snippet).
It also mentions production of generic "synthetic fuels, chemicals, or other energy carriers" in the 2nd snippet.
