Our Technology

Integrated Thermochemical Conversion — From Biomass to Carbon-Negative Products

Vivent Energy's platform combines pyrolysis, gasification, gas upgrading, and CO₂ capture in a single integrated process — extracting maximum value from waste biomass while achieving net-negative carbon across the system boundary.

Technology
The Platform

Where conventional bioenergy plants choose between pyrolysis or gasification, Vivent Energy's integrated reactor runs both in sequence — simultaneously producing biochar and syngas from a single feedstock pass.

Five Stages From Feedstock to Final Products

Every stage of the process is instrumented, automated, and remotely monitored — enabling consistent product quality across different feedstock types and operating environments.

🌾

Feedstock Preparation

Biomass is dried to <15% moisture, shredded, and sized for reactor feed. Accepts crop residues, wood chips, husks, and energy crops.

🔥

Pyrolysis Stage

Biomass enters the primary reactor at 450–600°C in an oxygen-limited environment, producing biochar and a volatile pyrolysis vapour stream.

💨

Gasification Stage

Pyrolysis vapours are thermally cracked in the secondary high-temperature zone (850–1,100°C), producing clean hydrogen-rich syngas.

⚗️

Gas Upgrading

Syngas is cooled, cleaned of tars and particulates, and upgraded to biomethane via methanation or to hydrogen via water-gas shift and PSA.

📦

Product Dispatch

Biochar is collected, CO₂ is captured, and clean fuel (bio-LNG, H₂, or biomethane) is metered, certified, and dispatched to offtake buyers.

🔥

Biochar Output

Solid carbon product collected after pyrolysis stage. 70–85% fixed carbon. Registered on Teravanet for carbon credit issuance.

❄️

Bio-LNG / H₂ Output

Upgraded syngas liquefied into bio-LNG or reformed into hydrogen. Dispatched via cryogenic tanker or tube trailer.

🌫️

Captured CO₂

Point-of-production CO₂ capture. Food-grade or industrial purity. Delivered to beverage, greenhouse, or sequestration buyers.

Why the Vivent Platform Is Different

Integrated Pyrolysis-Gasification

Most facilities do one or the other. Our sequential reactor design does both in a single thermal pass — producing high-quality biochar and clean syngas simultaneously without process trade-offs.

No Catalysts or Wet Scrubbing

Our high-temperature gasification zone thermally cracks tars without catalysts or wet gas cleaning — dramatically reducing operating complexity, maintenance cost, and wastewater management requirements.

Electrically Self-Sufficient

A fraction of the syngas powers an onsite generator. The facility draws no electricity from the grid — making it fully deployable in off-grid or weak-grid environments throughout the Global South.

Flexible Feedstock Tolerance

The platform is engineered to handle a wide range of lignocellulosic feedstocks — from rice husks and sugarcane bagasse to woody biomass and palm residues — without reactor redesign.

Container-Deployable

Every component is designed to fit into standard ISO shipping containers, enabling rapid deployment by road, rail, or sea to locations far from conventional industrial infrastructure.

Three Revenue Streams Per Facility

By producing biochar carbon credits, clean fuels, and captured CO₂ simultaneously, projects remain economically viable even when individual commodity markets are under pressure.

Why the Full System Boundary Is Net Negative

CO₂ absorbed by biomass feedstock+100%
Carbon locked in biochar (permanent removal)−32%
CO₂ captured at point of production−28%
Fossil fuel displaced by bio-LNG / H₂−22%
Process emissions (transport, utilities)+8%

Net Result: Carbon Removed From the Atmosphere, Not Just Reduced

When the full system boundary is drawn — from biomass growth absorbing atmospheric CO₂ through to biochar permanence, captured CO₂, and fossil fuel displacement — a Vivent Energy facility removes more CO₂ from the atmosphere than its operations emit.

This is Bioenergy with Carbon Capture and Storage (BECCS) in its most practical form: deployed at the scale of farming communities, not requiring large centralised infrastructure, and generating income for land stewards.

MRV and monitoring

Every Tonne Measured, Reported, and Verified

Vivent Energy facilities are instrumented for continuous feedstock metering, product yield measurement, and process carbon accounting. All data feeds into our digital MRV platform, which generates audit-ready reports for carbon credit verification and regulatory compliance.

Biochar carbon credits are verified by accredited third-party auditors and issued on the Teravanet Carbon Removal Registry — the same registry used by Vivent Carbon for nature-based credits across the Global South.
