DECARBONISING OUR OPERATIONS
Progressing our emission-reduction roadmaps
Our long-term ambition is to decarbonise our operations, with an intermediate goal of achieving
a 30% reduction in absolute scope 1 and 2 emissions by 2030 (off a 2017 baseline). We are guided
by our three-pillar emission-reduction framework: to REDUCE our emissions, TRANSFORM our operations
and SHIFT our portfolio in a stepwise manner.
Since we first published our GHG emissions inventory in
1996, we have been implementing various initiatives to reduce
our atmospheric emissions, increase energy efficiency and lower
our overall environmental footprint. Following the recent
announcement of our revised GHG targets and milestones in 2021,
Sasol has been executing against our roadmaps to deliver on these
targets (see page 4). Our roadmaps are underpinned by a series of
critical enablers aimed at delivering a just transition and ultimately
a net zero ambition by 2050.
CRITICAL ENABLERS IN OUR 2030 EMISSION-REDUCTION ROADMAPS
We are developing and accelerating various projects in the following areas:
RENEWABLE
ENERGY
Sasol Energy
In 2021, we put forward concrete plans to deliver an ~25% reduction of
our 30% target through known and available technologies. We indicated
that technology solutions were being evaluated and developed to close
the remaining gap to achieve our committed 30% reduction by 2030.
Since then, we have refined our 2030 roadmap, with better definition
of our mitigation levers and have a higher confidence in our ability to
achieve the target.
We are considering the introduction of additional volumes of natural
gas into the process to be a substitute for coal. This is enabled by
adding more reforming capacity. Natural gas can be used more
efficiently in the CTL process and can be converted to product without
increasing GHG emissions. We are exploring all available opportunities
to source additional gas from our own fields and exploration activities,
as well as LNG.
Sasol Chemicals
The Chemicals Business reaffirms its commitment to an absolute
reduction of GHG emissions of 30% by 2030 off a 2017 baseline and
an ambition to achieve net zero emissions by 2050.
This year, Sasol Chemicals focused on the implementation of the 2030
emissions-reduction roadmaps for Eurasia and North America and the
development of lower-carbon solutions with our customers. We
continue to evaluate and explore interventions that can be used to
accelerate our decarbonisation and integrate into our roadmaps.
Refinement of the Sasol Chemicals roadmaps is a continuous
improvement process with further developments expected in response
to any legislation changes or opportunities that materialise in this very
dynamic space.
Since the roadmap was approved in August 2021
For our South African operations, reductions will be achieved by first
decreasing the amount of coal we feed to Secunda’s gasifiers. This,
coupled with a suite of energy efficiency projects, allows for turndown
of approximately six boilers. To turndown Secunda’s boilers, which were
built to utilise fine coal, a co-product from mining coarse coal needed
for gasification, we are developing innovative solutions that utilise the
fine coal as a feedstock. The combination of turning down boilers and
reducing coal to gasification reduces coal demand by ~25% (equating
to 10 million tons) to meet both our air quality objectives and reduce
GHG emissions.
NATURAL GAS AS
A TRANSITION
FEEDSTOCK
• Through Sasol Energy’s Renewable Energy Implementation Programme (REIP) – one of the largest
private renewable energy procurement initiatives in South Africa – we have committed to procure
1 200 MW1 by 2030 and are in advanced stages of wind and solar energy procurement in excess of
600 MW before end-2025.
• We recently concluded PPAs of 29 MW for our sites in Germany and Italy and are identifying other
opportunities across our operations globally.
• The procurement of affordable gas and evaluation of alternative supply options are continuing at pace.
We have committed US$1bn to be spent over the next three years to secure additional gas from our
own reserves and have extended the gas plateau to 2028.
• We are also working with partners to evaluate other adjacencies in Mozambique. We are advancing on
the finalisation of a term sheet to secure 40 – 60 PJ/a of gas via Matola for delivery in 2026. In parallel,
we are evaluating other options to secure LNG including Richards Bay.
• Progressed to final investment decision for Sasol’s first green hydrogen project in Sasolburg, with
green hydrogen production commencing towards the end of 2023.
• Advancing work on the green hydrogen road mobility pilot, with first runs planned for 2023.
GREEN
HYDROGEN
• The pre-feasibility study for the strategic and catalytic Boegoebaai green hydrogen hub in the Northern
Cape is progressing well. This project will support significant socio-economic development in this region.
• Concluded a policy advocacy roadshow both locally and globally to enable acceptance of low-carbon
products produced from fossil-fuel-reliant countries, such as South Africa, in developed markets like
the EU.
• Further clarity on affordability of green hydrogen is expected closer to 2030.
• As part of our plans to reduce GHG and sulphur dioxide (SO2) emissions in an integrated manner, we
intend turning down some of Secunda’s boilers. The first boiler is expected to be turned down by 2025.
BOILER
TURNDOWN
AND A FINE COAL
SOLUTION
CCS
• Boiler turndown is anticipated to deliver a 30% load reduction in SO2, in addition to reducing GHG
emissions, as well as improving water intensity, ambient air quality and waste volumes.
• We submitted our boiler SO2 application for an alternative load-based limit to the Department of
Forestry, Fisheries and Environment on 29 June 2022.
• We have identified four technology solutions to manage fine coal waste. One technology option, a
solution to briquette the fine coal for use in gasification has been deemed ready for implementation.2
(see page 27).
• CCS technologies are being incentivised by the United States federal government. A Request for
information (RFI) process is underway to identify technologies suitable for CCS deployment at Lake
Charles. A pre-feasibility study is also underway.
• We are exploring a partnership with Globeleq to sequester CO2 from gas-fired power plants in
Mozambique and have partnered with the Council for Geosciences (CGS) to demonstrate at pilot scale
CO2 sequestration in Mpumalanga.
1.Joint procurement with Air Liquide.
2. Final technology selection for use in Secunda is underway.
