Markets we operate in
Renewable Energy
Tidal / Solar / BESS
As renewable generation scales rapidly, grid resilience is becoming the next critical challenge. With curtailment reaching record levels, the focus must shift from generation alone to smarter storage, flexibility and redeployment when demand peaks.
We connect generation, consumption and storage to unlock more value from every unit of energy. Combining experience across renewables, hydrogen and carbon capture, PTNZ delivers integrated solutions optimised for the entire value chain.
- Tidal
- Solar
- BESS
- Grid flexibility
Hydrogen
Hydrogen is no longer a one-size-fits-all market. Regional resources, industrial demand, infrastructure and policy are shaping very different opportunities. The Middle East and Southeast Asia are emerging around hydrogen derivatives and industrial applications, while Europe is using hydrogen to tackle hard-to-abate emissions across industry and transport.
The opportunity now lies in connecting production to demand. From production to refuelling and hydrogen-to-power, PTNZ brings together proven technology, trusted partners and system integration expertise to deliver practical hydrogen solutions.
- Production
- Refuelling
- H₂-to-power
- Derivatives
Carbon Capture
The next phase of industrial decarbonisation will require more than electrification. For hard-to-abate sectors, carbon capture is becoming a critical part of the solution, with the market now shifting from technology development towards integrated, scalable and commercially viable CCUS systems.
Carbon capture shouldn't operate in isolation. PTNZ integrates capture with energy generation, hydrogen, utilities and industrial processes to create practical decarbonisation solutions that work technically and commercially.
