Project Sprint breaks new ground in carbon management by using existing rail infrastructure to transport captured CO2, eliminating the need for extensive pipeline systems. CO2 is liquefied, loaded onto specialised railcars, and transported to the Granger Carbon Terminal in Wyoming—the world's first large-scale rail-to-sequestration facility. From there, it's permanently stored in Frontier's Class VI wells at the Sweetwater Carbon Storage Hub.
In phase one capacity is expected to reach 500,000 metric tonnes of CO2 annually, positioning Project Sprint as one of North America's most scalable carbon removal hubs.
Mangrove's digital MRV platform will ensure complete transparency from biomass sourcing through permanent storage. The system delivers real-time traceability and verifiable datasets required for Puro certification, third-party validation, and rapid credit issuance.
"This collaboration strengthens our commitment to high-integrity, scalable carbon removal," said Alicia Summers, Chief Development Officer of Frontier Carbon Solutions. "Mangrove's proven BECCS expertise ensures every tonne of CO2 we capture, transport, and store is backed by trusted, verifiable data—derisking Project Sprint operationally, commercially, and financially."
Mangrove's platform creates a single, auditable system of record by aggregating data across the entire value chain. By automating documentation and connecting directly with carbon registries, the platform accelerates credit issuance while ensuring complete CO2 accountability.
"Frontier is redefining how captured CO2 can be scaled and stored with integrity," said Brandon Vlaar, CEO of Mangrove Systems. "Our MRV foundation enables their innovative CO2-by-rail system to deliver the transparency today's carbon markets demand."
