The NET Nexus: A Closed-Loop, Carbon-Negative Energy & Material Ecosystem

The Negative Emission Technology (NET) Nexus is a revolutionary, closed-loop industrial ecology that transforms organic waste into pure hydrogen fuel while permanently locking away carbon dioxide as valuable mineral commodities.

By combining advanced pyrolysis, a reversible iron-redox loop, and an innovative desalination-driven chemical recycling network, we eliminate the trade-offs of traditional green energy. We don't just reduce emissions; we extract carbon from the economic cycle, powered entirely by our own waste heat.

The Five Pillars of the Core Technology

Our ecosystem operates through five seamlessly integrated thermodynamic and chemical loops:

♻️ 1. Waste to Carbon (C)

The Process: Municipal, industrial, or agricultural biomass waste undergoes high-efficiency pyrolysis or gasification.

The Output: This thermochemical breakdown isolates solid, pure Carbon (C) while yielding high-temperature Waste Heat Recovery (WHR) streams.

⚙️ 2. Carbon-to-Iron Reduction (Regeneration)

The Process: The isolated solid carbon is converted into Carbon Monoxide (CO) gas. This CO acts as a powerful reducing agent in a metallurgical reactor.

The Output: It reduces iron oxide (Fe3O4) back into pure active Iron (Fe), resetting the energy storage medium.

🔋 3. The Iron-Steam Redox Loop (Hydrogen on Demand)

The Process: Pure Iron (Fe) is exposed to superheated steam, undergoing an oxidation reaction back into Magnetite (Fe3O4).

The Output: This split-water reaction yields highly pure Hydrogen (H2) gas. Only this H2 is harvested and utilized as a zero-emission fuel for external commercial applications.

🛡️ 4. Direct NaOH CCU (Mineral Carbonation)

The Process: The Fe <—> Fe3O4 cycling and carbon reduction steps produce a concentrated stream of CO2. Instead of venting, this gas is immediately intercepted via a Direct Sodium Hydroxide (NaOH) Carbon Capture and Utilization (CCU) unit.

The Output: Permanently sequesters carbon by converting the gas into industrial-grade Sodium Carbonate (Na2CO3) or Sodium Bicarbonate (NaHCO3).

⚡ 5. CDI + BMED Desalination & sCO2 Power Loop

The Process: To sustainably supply NaOH without external chemical overhead, the system uses Capacitive Deionization (CDI) coupled with Bipolar Membrane Electrodialysis (BMED) desalination.

The Energy Source: This process is entirely energized by a Supercritical CO2 (sCO2) Electricity Generation loop, which is thermodynamically driven by the Waste Heat Recovery (WHR) captured directly from the Pyrolysis and Iron Reduction stages (Pillars 1 and 2).

The NET Nexus transforms environmental liabilities—waste, carbon emissions, and industrial brine—into high-value assets: green hydrogen, clean water, and industrial minerals. We are seeking strategic partners, energy transition funds, and industrial host facilities to co-develop our pilot-scale demonstration plant. This technology is developed at www.biocom.id.
