What do net-zero ambitions mean for energy technology?

• A growing number of governments and companies are making ambitious pledges

to reach net-zero emissions in the coming decades.

• Major progress has been made: the rise of solar PV, wind and batteries has

significantly reduced the costs of renewable electricity and electric cars.

• But an energy system transition to net-zero emissions requires broader

technology efforts in three critical areas:

• Existing assets in power generation and industry

• Clean energy innovation

• Infrastructure that enables rapid technology deployment

Focusing on the power sector is not enough to reach climate goals

Clean energy technology progress in the power sector is encouraging, but alone not sufficient to reach energy and

climate goals. About half of all CO2 emissions today are from industry, transport and buildings.

Heavy industry


Emissions from heavy industry sectors are ‘hard to abate’

Fossil fuels account for around 85% of the final energy used in heavy industries, which, combined, account for just

under a fifth of total energy system CO2 emissions.

Existing capacity is the starting point for the transition

Around 50% of the existing stock of ironmaking equipment is based in China, with India contributing a further 5%.

The current stock is quite young, with a global average age of 13 to 14 years for blast furnaces and DRI furnaces.

Steel continues to play a pivotal role across multiple end-use sectors

Global demand for steel is projected to increase by more than a third through to 2050 in our baseline projection.

In the Sustainable Development Scenario, demand is reduced through material efficiency strategies.

A portfolio of mitigation strategies is required

Technology performance improvements and material efficiency deliver 90% of annual emission reductions in 2030. In

the longer term, innovative technologies such as CCUS-equipped and hydrogen-based production are required.

Innovation is key to delivering deep emissions reductions

In the Faster Innovation Case, demonstration and prototype stage technologies contribute nearly three times as

much emissions reductions in 2050 as in the Sustainable Development Scenario.
