Carbon Removal Technologies

What is Biochar?

Biochar is a stable, carbon-rich material created through pyrolysis, heating organic biomass in low-oxygen conditions, that stores carbon in soils for centuries while improving soil fertility and water retention.

Sentinel Earth structures biochar carbon removal projects from feedstock sourcing through verification and credit issuance. Our Dark Earth project, registered with Puro.earth, is Singapore's first biochar carbon removal initiative. Inspired by ancient terra preta soil practices, the project converts organic waste into stable biochar through controlled pyrolysis, locking carbon away for centuries while improving soil health.

What is Direct Air Capture (DAC)?

Direct air capture (DAC) is technology that uses chemical processes to capture carbon dioxide directly from ambient air, concentrating the CO₂ for permanent geological storage or utilization in products and materials.

What is Carbon Capture and Storage (CCS)?

Carbon capture and storage (CCS) is technology that captures CO₂ emissions from industrial point sources or directly from ambient air, then transports and injects the captured carbon into deep geological formations for permanent storage.

What is BECCS?

BECCS combines bioenergy production with carbon capture technology, generating renewable energy from biomass while capturing and permanently storing the resulting CO₂ emissions underground, creating net carbon removal.

What is Decarbonization Pathway?

A decarbonization pathway is a strategic plan outlining specific actions, timelines, and milestones for reducing greenhouse gas emissions over time, typically targeting net-zero emissions by 2040-2050 aligned with climate science.

Sentinel Earth helps organizations design decarbonization pathways that prioritize internal emission reductions while strategically deploying carbon credits for unavoidable residual emissions and Scope 3 challenges.
