Deep decarbonisation ‘still 15 years away’ – DNV GL forecast

15 September 2020

Although decarbonisation is rising rapidly up the agendas of industry and governments, deep decarbonisation of the world’s energy system is still 15 years away, with carbon emissions set to remain high until the mid-2030s, according to a new forecast of the energy transition by DNV GL. 

Carbon dioxide emissions from energy use will fall just 15% to 2035, before then dropping 40% to 2050. The oil and gas industry will account for more than 80% of world energy-related carbon emissions in 2050. 

DNV GL’s ‘Energy Transition Outlook 2020’ provides an independent forecast of developments in the world energy mix to 2050. In a dedicated oil and gas report, DNV GL presents the demand, supply, and investment forecast for hydrocarbons and decarbonised and green gases to 2050, and focuses on the outlook for decarbonising the oil and gas industry.  

The energy transition DNV GL forecasts is still nowhere near fast enough to deliver on the COP 21 Paris Agreement – which aims to keep global warming to ‘well below 2°C’ and to limit the increase to 1.5°C. DNV GL’s forecast shows that the world will exhaust the 1.5°C carbon budget under the Agreement in 2028 and the 2°C budget in 2051.  

“Pressure is increasing on the oil and gas industry to decarbonise, and this is coming from all sides: from society and governments, from investors, and also from people within the industry itself. We see the sector increasingly putting the energy transition at the centre of its agenda, but climate change and ambitions to reduce it are outpacing action. The industry needs to prepare for an energy system that does not accept the release of carbon emissions,” commented Liv A. Hovem, CEO, DNV GL – Oil & Gas.  

Commitments made by oil and gas companies indicate that emissions reductions in the short term will come largely from efforts to decarbonise oil and gas production. Solutions include electrifying oil and gas assets, reducing flaring and venting of gas during production, increased efforts to detect and stem methane leaks, and efficiency gains through digitalisation. However, oil and gas production and distribution accounts for only a quarter of the industry’s carbon emissions; the majority  occurs during the combustion process. 

In 2050, DNV GL expects that the industry will broadly not be measured on carbon emissions per barrel of oil or gas it has produced, as is the default today, but by lifecycle emissions per barrel of oil or gas consumed. This includes so-called ‘scope 3 emissions’, which include all emissions from combustion or use of oil and gas products. DNV GL notes that while there are limited options to reduce emissions from oil consumption, other than shifting to another energy source, natural gas consumption can be decarbonized through deploying CCS technology.  

Hydrogen and carbon capture key components for deep decarbonisation 

Hydrogen and carbon capture and storage (CCS) have the potential to decarbonize fossil fuels more deeply. These technologies could transform the oil and gas industry’s ability to remove significant amounts of carbon emissions.  

DNV GL forecasts that: 

  • Fossil fuels will account for 54% of primary energy supply in 2050, compared to around 80% today 
  • Much of this supply will come from natural gas, as it becomes the world’s largest energy source from the mid-2020s
  • Only 13% of natural gas will be decarbonised in 2050, with 12% of world energy emissions captured by CCS – most from natural gas
  • The transformation to decarbonising gas will not scale for another 15 years, and only really gets going in the 2040s.  

“The transition to renewables and efforts to cut carbon intensity will significantly reduce emissions, but they will not deeply decarbonise natural gas, which the world’s energy system will depend upon for years to come. It is only by removing the carbon from natural gas – before or after combustion – that the oil and gas industry can deeply decarbonise, reaching hard-to-abate sectors throughout the value chain,” said Hovem. 

Decarbonised and green gases could have a bright future following the transformation, enabled by hydrogen and CCS complementing increased use of renewable electricity, battery technology and alternative low-carbon fuels such as ammonia to provide societies with a secure, affordable supply of clean energy.  

Public energy policies are key, not just in setting out the path for the world and the oil and gas industry to decarbonise, but also in deciding how quickly it heads down that path. DNV GL points to policies in Europe, China and North America that will create the impetus for scaling hydrogen and other low-carbon fuels, and propel recognition that scaling CCS will be essential to meet climate targets.  

Ultimately, these policies could transform the oil and gas industry into the decarboniser of hydrocarbons and supplier of carbon capture and storage. DNV GL forecasts that the mid-2030s is the point at which these decarbonisation policies will begin to act as a catalyst for this transformation. 

Governments need to enact policy to stimulate greater uptake of the technologies that will decarbonise industry, according to DNV GL. The quicker that government incentivises industry to adopt technology, such as through a competitive carbon price, the quicker the industry takes the technology down the cost-learning curve for it to become independently financially viable.  

“Forming partnerships among government, industry, and associations will be crucial in scaling innovation and new technologies for decarbonisation. Collaboration on frameworks for making hydrogen and CCS safe, effective, and commercially viable will give the oil and gas industry the certainty it needs to manage new risks and accelerate its transformation towards a low-carbon future,” said Hovem.
