An illustration of five decarbonisation pathways leading to a facility

Decarbonise and move to a circular economy

Comply with legislation and remain viable and profitable

Decarbonisation pathways

Companies across a wide range of sectors are under growing pressure to decarbonise, but deciding which pathways to adopt can be challenging. How will they impact your value chains? And what are the potential costs, risks and rewards?

As an owner-operator, Shell understands and shares your motivation. Our target is to become a net-zero-emissions energy business by 2050. To do so, we are transforming our business. Part of our strategy is to play an integral role in helping the decarbonisation and sustainability journeys of our customers, especially those in the hard-to-abate and refining and petrochemical industries.

At Shell Catalysts & Technologies, we are working with our customers to build and strengthen integrated decarbonisation and sustainability value chains, including:

  • renewable fuels;
  • plastic circularity;
  • hydrogen;
  • carbon capture and storage (CCS); and
  • syngas products.

These value chains overlap and intersect in many ways, but considering them individually highlights which integrated technology blocks, proven and in development, can help you to accelerate the transition to lower carbon and more sustainable products and feedstocks. Because we are starting to do this ourselves in our Energy and Chemicals Parks, we know how to help integrate these solutions to strengthen your value chains.

Renewable fuels

Reducing fuel carbon intensity in line with changing legislation

We can share insights from Shell’s established value chain for the production of renewable fuels from various feeds, and the new technologies we are developing to process more difficult and plentiful feedstocks.

Did you know?
IH2 technology produces drop-in biofuels from wood biomass and municipal solid waste with up to 72% bioenergy recovery and up to 92% greenhouse gas emission reduction.

Plastic circularity

Processing a higher volume and wider range of recovered plastic feeds

Processing a broad range of plastic waste introduces contaminants and impurities to the feed, limiting useable quantities.

Shell’s proprietary upgrader technology removes these impurities, enabling the use of a wider range of feeds for the production of circular chemicals.

Did you know?
Shell has an ambition to recycle 1 million tonnes of plastic waste in its chemical facilities by 2025 and is investing across the plastic waste value chain to achieve this. It is already processing plastic waste feedstocks at Norco in the USA and will expand this to include plants in Europe and Asia.

Shell has also announced plans to build two upgrader units: one at Shell Energy and Chemicals Park Singapore and the other at Shell Chemicals Park Moerdijk in the Netherlands.

Fuelling processes with low-carbon hydrogen

The increasing cost of carbon emissions makes decarbonised hydrogen an attractive option. The Shell Blue Hydrogen Process (SBHP) produces low-carbon hydrogen from natural gas, paired with carbon capture and storage.

Did you know?
Shell Gas Partial Oxidation (POX), used by the SBHP, can lower the levelised cost of hydrogen, compared with other oxygen-based systems.

Carbon capture and storage

Mitigating emissions with carbon sinks

Carbon capture and storage (CCS) offers one of the lowest-cost ways of reducing CO₂ emissions in carbon-intensive industrial processes, according to the International Energy Agency.

Shell is helping to develop large-scale commercial CCS projects, and Shell Catalysts & Technologies has developed two leading carbon capture technologies.

Did you know?
Shell is working with Equinor and Total Energies on the Northern Lights CCS project to inject and store up to 1.5 million tonnes per annum of CO2. This project recently achieved an important decarbonisation milestone – the world’s first commercial agreement on cross border CO2 transport and storage. With its joint venture partners Shell will transport 800,000 tonnes of CO2 from Yara International's ammonia and fertiliser plant in the Netherlands and permanently store it under the seabed in the Norwegian North Sea.

Syngas products

Producing low-, even negative-, carbon-intensity renewable fuels, chemicals and lubricants from multiple feedstocks

Low-carbon-intensity syngas can be created by gasifying biomass, municipal waste and plastics using the Shell Gasification Process or from renewable power and biogenic CO2 via power-to-liquids (PtL) technologies. Fischer–Tropsch and hydroprocessing technology then converts the syngas to numerous products, such as fuels, chemicals and lubricants.

Did you know?
In Germany, Shell announced an ambition to produce sustainable aviation fuel at Shell Energy and Chemicals Park Rheinland. The capacity of a commercial bio-PTL plant would initially be around 100,000 tonnes per year. The project awaits final investment decision.
