SB 840 (2016), a Senate Budget and Fiscal Review
Committee trailer bill, requested that CCST complete a
study analyzing the minimum heating value and maximum
siloxane specifications for the delivery of biomethane to
the public gas pipelines, and their impacts to cost, volume
of biomethane sold, equipment operation, and safety.
This is important as it will affect biomethane producers,
public utilities, and consumers. The study considered
and evaluated other states/ standards, the source of
biomethane, the dilution of biomethane after it is injected
into the pipeline, and the equipment and technology
upgrades required to meet the specifications.
Incoming CCST Council Chair and Stanford University
Professor Jim Sweeney was chosen to serve as Steering
Committee Chair for this report, and Stanford University
Professor Adam Brandt served as the lead researcher.
The report was completed in June 2018.
