*Annie Nguyễn – 06/03/2026*
Carbon Nova is a China‑based company operating in the hydrogen energy technology sector. The company focuses on core technology R&D and high‑end equipment manufacturing across the entire hydrogen industrial chain – from production, storage and transport to end‑use applications. Carbon Nova also provides full‑process technical services, from core equipment to system integration.
1. Carbon Capture Technology
Carbon Nova develops CO₂ capture equipment for industrial flue gas or direct air capture, using chemical absorption or physical adsorption methods.
-
Capture efficiency: Over 90%, among the industry’s best.
-
High‑performance solvent: Self‑developed to enhance CO₂ absorption reaction rates.
-
Optimized flow field design: Reduces gas‑liquid two‑phase resistance, improves mass transfer, and lowers pump load.
-
Modular design: Flexible and customizable to production line scale, supporting capacity expansion and parallel operation.
-
Energy consumption: Approximately 40% lower than traditional solutions, significantly reducing operating costs.
-
Capture cost: With green electricity at RMB 0.2/kWh, CO₂ capture and recycling cost can reach around RMB 381.3 per ton (electricity: RMB 284.2, equipment depreciation: RMB 91.8).
-
Applications: Suitable for heavy industries such as steel and cement plants.
2. Alkaline Electrolyzer (ALK)
ALK is the most mature and cost‑effective electrolysis technology, offering stable operation and low cost, ideal for large‑scale green hydrogen projects in chemicals and metallurgy.

New welding process for support mesh and nickel mesh.
-
New electrode alloy material developed with domestic universities, improving efficiency and stability.
-
New hydrogen‑oxygen separator design for stable, impact‑free separation.
-
3. Proton Exchange Membrane Electrolyzer (PEM)
PEM technology is designed to handle the intermittency of renewable energy (wind and solar).
-
DC power consumption: ≤ 4.4 kWh/Nm³
-
Load range: 5% – 100%, with millisecond‑level dynamic response.
-
Operating pressure: 0.8 – 3.0 MPa
-
Core materials: 100% domestically produced. Precious metal usage reduced by over 50% using PVD sputtering, cutting coating costs by 30%.
-
Titanium‑titanium welding: Precision welding for bipolar plates, integrating the diffusion layer to reduce contact resistance.
-
Product range: Covers electrolysis cells from 2 Nm³ to 1000 Nm³.
4. AEM and Chlor‑Alkali Electrolyzers
-
AEM (Anion Exchange Membrane): Third‑generation technology combining ALK and PEM advantages. No precious metal catalysts, lower investment cost, low ohmic resistance, compact design. Suitable for small to medium‑sized green hydrogen projects, especially in industrial parks and hydrogen refueling stations.
-
Chlor‑alkali: Utilizes by‑product hydrogen from caustic‑chlorine production, converting it into green energy at very low marginal cost, offering a low‑cost decarbonization pathway for existing chemical industrial parks.
5. Energy Management System (EMS) and Simulation
Carbon Nova provides a renewable‑energy hydrogen production simulation system, covering grid‑connected/off‑grid, AC/DC scenarios, and multiple energy management strategies.
-
EMS functions: Wind/solar power forecasting, dynamic balancing between renewable generation and hydrogen production load, economic operation optimization, intelligent operation management, and predictive maintenance.
-
Electrolyzer cluster control: Start/stop strategies for power supply groups, dynamic adjustment of multiple sources, fault handling.
6. Digital Twin Smart Platform
Carbon Nova has developed a “Digital Smart Platform for Integrated Hydrogen Energy Stations” using AI and digital twin technology:
-
Real‑time (millisecond‑level) monitoring of equipment status, hydrogen flow, and energy consumption.
-
Intelligent dispatching of refueling loads to balance supply and demand.
-
Predictive maintenance based on historical data to forecast potential equipment failures.
