GREEN HYDROGEN PRODUCTION
The approach: A systems design approach
was pursued that would result in
significant reduction of the amount of
reject water from the WTP, along with
the reduction of the size of the evaporation
pond, or preferably its elimination.
Reducing the reject water required
close interaction with water treatment
specialists and vendors. It is critical to
understand the characteristics of the
water produced from the aquifer, so the
aquifer water was retested. The result
from the water analysis was used to optimize
the design of the WTP and minimize
the amount of reject water, eliminating
two-thirds of the amount of reject
water initially estimated.
Rather than sending the reject water
to an evaporation pond, the reject water
was also formulated to meet the local
Australian regulatory requirements
of total dissolved solids (TDS), which
could enable its discharge to ground water.
Several options for recycling water
are being evaluated.
The availability of freshwater to produce
demineralized water may not always
be possible in some regions where
freshwater is a scarce resource, such as
the Middle East. Other water sources,
such as seawater, will require more expensive
treatment to achieve the water
quality needed for electrolyzer units,
leading to higher CAPEX and higher
utility and energy demands. The disposal
of reject water from seawater demineralization
can also be subject to stringent
environmental regulations, requiring
detailed studies focused on its impact on
the marine environment. This should be
considered when developing green H2
projects in such regions.
Part 2. Part 2 of this article, to be published
in the Q1 2022 issue, will examine
the challenges and solutions for largescale
H2
and process safety considerations. It will
also examine cost considerations for the
deployment of green H2
worldwide.

CHET
BILIYOK is a Chartered
Process Engineer with 16 yr of
experience in process design,
project execution, technical
consultancy and R & D across the
energy industry. He has drawn on
previous experience working in oil
storage, equipment supply chain
and gas to deliver projects in renewable/low carbon
H2, carbon capture, utilization and storage (CCUS)
and waste-to-fuels, recently serving as the Process
Lead during FEED of the Arrowsmith Green
Hydrogen Project. Dr. Biliyok has authored more than
20 peer-reviewed journal articles and presented his
work at major international conferences. He is based
in Petrofac's Woking, UK office as the Technical
Director of Petrofac's New Energy Services and
seeks to deliver solutions that enable organizations
to thrive in a low-carbon energy future.
MICHAEL CZARNECKI is a

Study Manager supporting Petrofac's Engineering
& Consultancy services team in Petrofac's Woking,
UK office. Mr. Czarnecki recently project-managed
the Arrowsmith Green Hydrogen FEED Project.
This project involved the integration of wind turbine
and solar PV technology to electrolyze H2
from raw
water. He has a keen interest in low-carbon projects
and new technologies and is applying his experience
of working within the onshore and offshore oil and
gas sectors to new energy projects.
AHMED DAR has more than
