Seaport Demonstration Plant
7
Facility overview
• The Seaport Demonstration Plant located in
Redwood City, CA (“Seaport”) was completed
in September 2014
• Carbon black production started in April 2015
• First greenfield carbon black facility in the
United States in ~30 years
• Permitted and operating on the San
Francisco Bay, approximately 200 yards
away from the Don Edwards National
Wildlife Refuge
• Reactor with 700 metric tons of carbon
capacity and 200 metric tons of Hydrogen
capacity per year.
• Plant was decommissioned in the fall of 2018
after successfully demonstrating technology.
Over 3,700 operating hours achieved

● First commercial greenfield carbon black facility to be built in the U.S. since 1980s
Contemplated build-out in three distinct phases: 14kT → 80kt → 160kT
● Lowest cost supply of electricity from Nebraska Public Power District (“NPPD”)
Co-located with NPPD’s Sheldon Power Station near Lincoln, Nebraska
● Competitive supply dynamics for natural gas from major hubs and firm transport
agreement in place
Located at cross-roads of natural gas pipelines coming from every major shale hub
Overview of First Commercial Project (Nebraska)
● Long-term, fully contracted offtake agreement for
hydrogen co-product executed with NPPD
Sheldon Station will switch boiler unit
from coal over to hydrogen
● Creates construction and permanent jobs
100 direct and 550 indirect jobs for
Phase I and Phase II combined
8
● Olive Creek Phase I is essentially full-scale
Olive Creek Phase II and further plant expansion
process is modular once Olive Creek Phase I is
complete

● Basis – Electrical pyrolysis of methane
● Cost of H2 – depends on carbon value:
● With high value for carbon: least expensive way to produce H2.
● Technology Maturity – Full scale unit operating by end of 2020.
● Environmental – no direct CO2 produced. Full lifecyle depends on CO2 intensity of
electricity consumed in process.
