The Oxy+ process operates in an oxygen-rich environment, which improves combustion efficiency and reduces emissions. Here’s how the process works:
Step 1: Introduction of Pure Oxygen
The process starts by replacing combustion air with oxygen in the process while maintaining the design and structure of the boiler. This oxygen-rich environment enhances combustion efficiency and allows for the effective use of carbon-neutral fuels, such as biomass and waste residues.
Step 2: Recirculation and CO2 Capture
The performance of the energy generation plant is maintained by the partial recirculation of the product CO2 stream. This enables the efficient control of the temperature and chemical reactions taking place in the boiler and producing an already enriched CO2 stream for further processing without the need for a dedicated capture plant.
Step 3: Enhancing Plant Performance
The SFW Oxy+ system integrates carbon capture seamlessly. In some cases, it improves energy generation efficiency and overall plant performance. By reducing both energy consumption and the footprint needed for carbon capture, it ensures operations remain efficient.
Versatile Integration
The technology is highly adaptable, suitable for small-scale decentralized heating systems, industrial boilers, and large-scale utility power plants. It can be applied to existing plants as a retrofit or implemented in new iFnstallations, offering flexibility across various energy projects.
Lowest energy penalty for carbon capture
This innovative technology results in lower energy penalties compared to traditional CO2 capture methods. When integrated with existing systems, oxy-fuel technology enhances the overall performance and energy output of the plant.
Advanced CO2 Capture and Utilization
By using pure oxygen and recirculated CO2, the technology produces a high-purity CO2 stream ready for capture and storage or further utilization in chemical synthesis, enabling a circular economy.
Sector Coupling and E-fuel plant integration
Oxy-fuel technology supports sector coupling by integrating with hydrogen-producing electrolysers or air separation units. By utilizing by-product oxygen from these processes, the technology reduces CO2 capture costs and enables the production of renewable gases, including hydrogen, concentrated nitrogen, and argon. This symbiotic relationship accelerates the decarbonization of hard-to-abate sectors, such as chemicals, materials manufacturing, and beyond.
Demonstrated and Validated Technology
Sumitomo SHI FW’s Oxy+ technology has been rigorously tested and validated at a 30 MWth scale plant in Compostilla, Spain, as well as in several smaller pilot plants across Europe and globally. Built on SFW designs, this technology has successfully operated for thousands of hours, showcasing its reliability and efficiency in real-world conditions.
Enables Carbon Negativity
When combined with the treatment of non-recyclable fractions of biomass and waste, the technology not only reduces emissions but actively removes CO2 from the atmosphere. This capability is crucial for meeting ambitious climate targets and moving beyond net-zero to carbon-negative energy production.
Enhanced Plant Efficiency
The integration of Oxy+ technology into existing or new plants results in a lower environmental impact per unit of energy produced and greater overall plant performance.
Flexible and Cost-effective Deployment
The technology’s adaptability for retrofitting existing infrastructure or integration into new projects offers cost savings and flexibility for various energy producers. Its compatibility with a wide range of fuels and industrial symbiosis capabilities further reduces operational costs and enhances project viability.
Support for Green Hydrogen and E-fuel Production
By utilizing by-product oxygen from hydrogen production, the technology not only lowers CO2 capture costs but also contributes to the production of green hydrogen and E-fuels such Methanol, Sustainable Aviation Fuels-SAF and Renewable natural gas (RNG) . This supports the growing demand for renewable hydrogen and aids in the decarbonization of sectors like transportation and heavy industry.
Reliable and Scalable Solution
With successful long-term operation in real-world conditions, Sumitomo SHI FW’s Oxy+ technology offers a reliable and scalable solution for large-scale energy projects. Its proven performance and adaptability make it an ideal choice for industries seeking to achieve both sustainability and energy security.
