PeroCycle partnerships aim to cut steel and cement emissions with carbon recycling technology

PeroCycle has announced partnerships with PKU Pioneer and io consulting to scale its closed-loop carbon recycling technology. The company uses a perovskite catalyst to convert CO2 into CO at lower temperatures, which can then be reused as feedstock in heavy industrial processes. The goal is to reduce emissions in steel, cement, and chemical production by up to 90 percent. The technology can be integrated into new builds or retrofitted into existing plants. The partners plan a 20 ktpa demonstration plant followed by a 2 mtpa commercial facility. If successful, this approach could lower energy demand and operating costs while cutting process emissions in sectors that are hard to decarbonize.

Interesting to see a perovskite catalyst being used for CO2 to CO conversion at lower temps. The 90 percent reduction claim for steel is big, but I want to see how they handle the energy balance at scale.

Yeah the 90 percent number sounds optimistic without a breakdown of scope. Is that direct process emissions only or full lifecycle? Also curious what the CO2 source is for the demo plant.

The 20 ktpa demo to 2 mtpa FOAK jump is ambitious. That is a 100x scale up. Would be good to know the timeline and what kind of power supply they are assuming for the process.

If this works, the circular carbon model could shift how we think about carbon credits for industrial emitters. But the policy framework for counting recycled CO as avoided emissions is still murky in most jurisdictions.

Retrofit flexibility is the part that matters most for existing steel and cement plants. If the catalyst module can be dropped in without a full rebuild, that changes the economics significantly.
