Making The
Energy Transition
Work For You

Energy transition refers to the implementation of solutions designed to help accelerate the shift to the use of more efficient energy sources, optimize asset energy use and help companies work toward their carbon reduction goals.

Carbon capture technologies provide industries with effective methods of carbon dioxide (CO₂) removal to prevent emissions from entering the atmosphere. Point-source carbon capture is often discussed in two broad categories:

• Post-combustion methods separate CO₂ from other exhaust gases and capture it using a variety of technologies, producing pure, storable CO₂.
• Pre-combustion methods convert fuel into a gaseous mixture of mostly hydrogen and CO₂. The CO₂ is compressed for later storage and the hydrogen is burned without producing any CO₂.

Today, a variety of technologies are available to support both methods for either greenfield projects or retrofits. Once captured, CO₂ emissions can be purified and compressed to enable transportation, storage and/or use as an input to other production processes.

Sustainable aviation fuel (SAF) is a lower-carbon alternative to conventional, petroleum-based jet fuel that is helping the aviation industry lower its carbon footprint. SAF is produced by converting abundant, renewable waste materials into a drop-in fuel to displace Jet A (a commonly used, kerosene-based jet fuel). The most common SAF feedstocks today include used cooking oil, non-edible plant oils like those from mustard seeds, or even certain waste animal fats. To help refiners meet expected demand, SAF production technologies have expanded to tap into other abundant waste sources, such as:

• Solid biomass or biogas from forestry and agricultural waste or even some parts of municipal solid waste
• Renewable hydrogen and captured carbon dioxide used to produce synthetic eFuels.

Regardless of the source materials, SAF is a fuel that is approved for use in existing aircraft when blended up to 50% with conventional jet fuel.

Green hydrogen is hydrogen fuel produced using a process that generates no carbon emissions and is powered entirely by renewable energy sources like wind or solar. The most common method is electrolysis, where electricity is used to separate water (H₂O) into hydrogen and oxygen. The purity of hydrogen determines its role in the hydrogen economy, so impurities must be removed through a separation process. In a science class, this might look like a beaker of water, metal strips connected to a battery and test tubes collecting the gases. On an industrial scale, simply choosing renewable energy to power electrolyzers is what makes the process green. Green hydrogen matters because it offers a cleaner alternative to fossil fuels, especially for hard-to-decarbonize sectors like industrial heating, helping reduce greenhouse gas emissions and supporting global climate goals.

Industrial heating involves the use of heat in manufacturing processes to shape, treat or transform raw materials such as metals, chemicals or food products into final goods. It accounts for roughly a fifth of all anthropogenic greenhouse gas emissions. Manufacturing plants use heat across a wide range of temperatures for many process applications so there’s no “one-size-fits-all” solution for reducing emissions. Greenhouse gas emissions mainly come from carbon dioxide released during combustion but also include methane, fuel system leaks, incomplete combustion and nitrogen oxides formed as a combustion byproduct.
