HYDROGEN SEEN BY IRENA
Hydrogen, object of desire, for some a mirage,
for others an obsession. In this issue we report
on Rolls-Royce PG applications and MAN
Engines’ dual fuel system for workboats.
Here are some passages from the report by
IRENA, International Renewable Energy Agency.
According to IRENA’s World Energy Transitions Outlook
“hydrogen will cover 12 percent of global energy
demand and will be cutting 10 percent of CO 2
emissions
by 2050. Yet, hydrogen can only be a viable climate
solution if the power needed to produce it comes in
addition to the electrification of the energy system,
placing an even greater uptake of renewable power at
the heart of the transition. If costs come down, green
hydrogen below USD 1 per kilogram (kg) would be
available to meet ten times the world’s energy demand
in 2050. The new reports see half of the hydrogen in
2050 being traded through largely existing, repurposed
gas pipelines drastically reducing the costs of transport.
With costs of around USD 0.10/kg per 1,000 kilometres
(km) in 2050, it would be the most cost-effective option
for less than 3000 km distances. By contrast, transportation
through new pipelines would cost twice as much. This is
still less than shipping it in the form of green ammonia
4
over 3,000-5,000 km, the other half of global hydrogen
trade. Ammonia shipping will become the dominant
form of intercontinental hydrogen trade, according to
the analysis. This future pipeline-enabled trade would
be concentrated in two regional markets namely Europe
with the vast majority of 85 percent of the hydrogen
trade and Latin America with 15 percent. Europe’s main
trading partners would be North Africa and the Middle
East while Australia could mainly supply Asia.
New trade markets would lead to different roles for
energy players. Some of the largest potential exporters
of hydrogen by pipeline in 2050 are Chile, North Africa
and Spain, representing almost three-quarters of the
pipeline trade market. Major consumers like China
and USA are able to produce most of their hydrogen
domestically. Africa, Australia and North America,
account for three-quarters of the global exports. On the
importing side, Japan, South Korea and the EU are
expected to satisfy a large share of their hydrogen
demand through imports. As hydrogen becomes an
increasingly internationally traded commodity, the
hydrogen sector will attract growing sums of international
investment. Satisfying the global hydrogen demand
requires an investment of almost USD 4 trillion by 2050.”
