–Ammonia: Used as a zero-emission fuel (ZEF)
in the shipping industry, ammonia can be
produced from green hydrogen or from natural
gas coupled with CCS.
–Methanol: Another clean fuel for shipping,
methanol can be produced from renewable
sources and offers a lower carbon footprint.
–Waste: Renewable municipal waste, sewage
and landfill gas, and residue waste are important
in some applications such as in kilns in the
cement industry.
The analysis shows that an average 61% of energy
needed in 2050 climate scenarios for heavy
transport sectors, and 21% for heavy industry
sectors will be sourced from clean fuels.
The sectors in scope often require high energy
density fuels (such as in shipping and aviation),
high temperature process heat (steel, cement)
or feedstock to produce secondary products
(chemicals). While some of these processes and
fuels can be replaced by other energy carriers (such
as electricity), many cannot, and there will be strong
competition for those clean electrons for uses in
other sectors. Thus, it is imperative that clean fuels
develop alongside electrification.
In the shipping industry, clean fuels such as
ammonia and methanol are essential to meet the
International Maritime Organization’s (IMO) targets
for achieving net-zero emissions by or around
2050. Ammonia and methanol offer an alternative
to traditional marine fuels, significantly lowering the
carbon footprint of maritime transport when they
are produced from low- to zero-carbon energy sources (such as biomass or clean electricity). In the
aviation sector, SAF is expected to play a crucial
role. SAF, derived from renewable feedstocks like
agricultural residues and waste oils, can reduce
lifecycle emissions by up to 80% compared to
conventional jet fuel. The analysis shows that
400 MTPA of SAF alone is needed in the sector by
2050. Meanwhile, the trucking industry is exploring
the use of hydrogen and biofuels to replace diesel,
thereby reducing emissions and improving air
quality; however, the sector can be more easily
electrified for certain transport cases.
In the heavy industrial sectors such as steel,
chemicals and cement, clean fuels are equally
critical. The steel industry is transitioning to green
hydrogen to replace coal in the production process,
and green hydrogen is expected to contribute to
21% of steel emissions reduction by 2050.53 The
chemicals industry receives 93% of its energy
from fuels but will also need to shift towards green
hydrogen, ammonia and methanol to reduce
emissions. In the cement industry, the use of
alternative fuels like biomass and waste-derived
fuels is being explored to lower the carbon footprint.
These transitions are not only essential for meeting
environmental targets but also for ensuring the
long-term viability and competitiveness of these
industries in a low-carbon economy.
Carbon capture utilization and storage (CCUS):
Hard-to-abate sectors such as cement, steel,
chemicals and aluminium are characterized by
emission-intensive processes that are challenging
to decarbonize using methods such as clean
power and process changes. To address this,
