Michael Nofal, H2scan, USA, and Robert H. Shelton,
H2C Safety Pipe, USA, look at ways to enhance the
safety and e昀케ciency of green hydrogen transport.
Hydrogen, the Earth's most abundant and lightest element,
is a safe, renewable, and clean resource capable of powering
the most energy-intensive industries. When used to produce
electricity in a fuel cell, hydrogen's only emission is pure
water. And, when hydrogen is generated through electrolysis
powered by renewable energy sources such as wind, sun,
geothermal, or hydropower, it becomes one of the most
promising cornerstones for a clean energy future and
essential to achieving the world's net zero goals.
gas, petroleum, and other non-renewable energy resources
to homes and businesses. Supplementing and, wherever
possible, repurposing this infrastructure for hydrogen will play
a pivotal role as nations transition to a hydrogen economy
over the coming decades.
Green hydrogen can be produced at competitive prices in
regions with abundant renewable energy, such as the Middle
East, North Africa, Chile, and Western Australia. However,
these areas are often thousands of miles from the major
consumer markets where hydrogen is most needed. This
geographic mismatch requires long-distance transport
solutions to economically bridge these vast distances, as
well as pipelines to e昀케ciently move hydrogen from regional
production and distribution centres to end-user locations like
major industrial facilities and vehicle dispensing centres.
To address these issues, there is an increasing focus on
developing 'midstream' solutions. A number of industry
players are developing technologies to transport liquid hydrogen
across thousands of miles, from areas where it can be
produced economically, and distributing gaseous hydrogen
at scale using pipelines that are lower in cost and safer than
the options available today.
The fossil fuel economy relies on major pipelines and 昀氀eets
of tankers that crisscross the globe from where crude oil is
produced to re昀椀neries and end-user locations. Nearly three
million miles of pipeline traverse the US, and an additional
300,000 miles traverse Europe, primarily delivering natural

A new approach to the safe transport
of hydrogen
Ideally, the distribution technology should utilise existing
infrastructure, such as oil and gas pipelines, water pipes,
sewer lines, and storm drains, to provide critical right-of-way
for these projects. This will help companies to avoid stranded
assets, reduce initial capital cost and deployment time, and
will help stakeholders lower environmental impact and
decrease disruption to city streets and roadways.
