Truck & Off-Highway Engineering - December 2021 - 15

MATERIALS FEATURE
Volvo's collaboration with
steel maker Ovako to make use
of surplus " green " hydrogen
also calls for the installation of
a hydrogen filling station for
fuel-cell trucks.
and coke. Water is the byproduct rather than CO2
emissions. Carbon will still be an alloying element in
the steel, SSAB noted.
" We'll be converting to electric arc furnace in
Oxelösund as early as 2025, " said Johnny Sjöström,
head of SSAB Special Steels Division. " This is the first
production site within SSAB to make the transition,
and it means that we'll already be cutting large
amounts of carbon dioxide emissions then. "
SSAB admits that fossil-free steel is a premium
product with a higher price tag than regular fossilbased
steel products. The main cost drivers are the
investments in production and infrastructure - to
switch from coal to fossil-free electricity and hydrogen,
from natural gas to biogas, and from iron ore pellets
to HYBRIT sponge iron.
The quality and properties of SSAB's fossil-free steel
are the same as its traditional steel, Lindqvist said. The
properties are still created in the steelmaking, rolling
and heat-treatment processes; the only difference is
that the energy used will be exclusively fossil-free
electricity and other fossil-free fuels.
SSAB plans to eventually have the full range of its
steel grades available in fossil-free steel. The order of
product roll-out, however, will be determined by customer
requests.
Demand for the green steel appears to be growing.
Just a few weeks after the Volvo product reveal, automotive
safety-systems supplier Autoliv announced a
collaboration with SSAB to research and develop fossil-free
steel components for safety products such as
airbags and seatbelts.
TRUCK & OFF-HIGHWAY ENGINEERING
SSAB Oxelösund in Sweden rolled the first steel produced using HYBRIT sponge
iron, which is reduced by 100% fossil-free hydrogen instead of coal and coke.
" We are committed to becoming carbon neutral in our own operations
by 2030 and furthermore aim for net-zero emissions across our
supply chain by 2040, " said Mikael Bratt, president and CEO of Autoliv.
" This means reducing our carbon emissions through use of renewable
electricity in our own and supplier operations, improving energy and
materials efficiency and adopting low-carbon logistics and low-carbon
materials. Gradually switching to fossil-free steel in our products is an
important step towards achieving our climate targets. "
Surplus 'green' hydrogen
Volvo Group also has a collaboration with steel maker Ovako to make use
of the surplus " green " hydrogen produced as part of Ovako's manufacturing
operations, to power its fuel-cell vehicles particularly for long-haul
