Nature Positive Role of the Ports Sector

The sustainable transformation of energy, materials,
equipment and operating systems is an important
action not only to contribute to a nature-positive
transition but also to reduce energy use and
improve operational efficiency, thereby reducing
costs and enhancing ports’ competitiveness.
In alignment with the IMO strategy to eliminate
GHG emissions within this century, a nature-
positive port should strive to become zero-
emission. This ambitious goal involves adopting
innovative technologies, sustainable practices and
eco-friendly operations to minimize environmental
impact, ultimately contributing to a cleaner and
healthier planet.
Ports should optimize their energy portfolio by
increasing the use of clean energy sources such
as renewable electricity or by installing wind
turbines, solar panels, geothermal energy solutions
and tidal energy facilities within the port area
where appropriate and feasible. Concurrently, it is essential to introduce and adopt advanced
energy management solutions (e.g. smart grid
management systems) alongside battery storage
systems. For example, with the container terminals,
PSA International aims to progressively transition
all diesel-based container handling equipment to
cleaner energy sources through electrification as
well as low or zero-carbon sources, like hydrogen.
Within the wider port value chain, ships account
for a significant share of GHG emissions. Many
shipping companies have taken actions to promote
the research, development and deployment of
low- or zero-emission marine fuels and advanced
propulsion technologies. To mitigate pollution
and GHG emissions and to reduce fossil fuel
dependency, ports should also improve or retrofit
storage and refilling facilities to accommodate
increasing quantities of green alternative fuels
needed for green shipping, including methanol,
hydrogen and ammonia. They should also invest
in the use of shore power for ships in port.3.2 Enhance the use of clean energy,
sustainable materials and advanced
equipment and operating systemsPriority action 2
Shore power refers to a way of supplying electricity to ships from
the onshore grid when the ship is moored at port. Compared
with the traditional ship generator power supply method, the
use of shore power has the advantages of pollution reduction,
energy savings, noise reduction and reduced maintenance
costs. Shore power can also effectively reduce fuel consumption
when ships are at berth, thereby reducing GHG emissions,
including carbon oxides, NOx, SOx and soot. Shore power
is being implemented globally at an increasing speed to ports
and different types of ships. The use of shore power requires
ports, shipping companies and power suppliers to work
together on building and maintaining infrastructure to ensure
a clean and reliable power supply to the ships. As a smart zero-carbon terminal, Tianjin Port Second
Container Terminal is powered by a wind power and storage
integration system, using 100% electric power, 100% green
power and 100% green power self-sufficiency, realizing
the carbon neutrality of the company’s production and
operation. The terminal is supported by green power, which
includes three fixed shore power units and one 440-volt
low-voltage mobile shore power unit, allowing up to three
ships to connect simultaneously. With a maximum shore
power capacity of 6,000 kVA (kilo-volt-amperes), these green
shore power units help significantly reduce ship emissions,
enhance the port’s overall energy efficiency and improve
its environmental sustainability.CASE STUDY 2
Tianjin Port In alignment with
the IMO strategy
to eliminate GHG
emissions within
this century, a
nature-positive
port should strive
to become zero-
emission.
Over the past few decades, container ships
have experienced rapid growth, with their average
capacity doubling in just one decade. The largest
container ship currently in operation can carry
24,346 TEUs. As the shipping industry continues to
evolve, ports are increasingly embracing the handling
of megaships. Modernizing port infrastructure to
support these mega-vessels presents an opportunity for integrating sustainable practices that mitigate
environmental impact. Automation is becoming more
prevalent: for example, Qingdao Port has established
a fully automated container terminal as the world’s
first “hydrogen+5G” smart green terminal, achieving
unmanned operations throughout the entire loading
and unloading process with a maximum efficiency
of 60.2 TEU per hour.92
