Modular PSA Oxygen Generators

PSA technology plays a critical role in ensuring continuous oxygen supply for astronauts during space missions. Unlike cryogenic systems, which require large storage tanks and constant refrigeration, PSA systems generate oxygen on demand using ambient air, reducing payload weight and operational complexity. China's Tiangong Space Station employs a hybrid life support system that integrates PSA for oxygen generation and electrolysis for water recycling. NEWTEK's modular design could enhance systems by providing redundant oxygen production capabilities, particularly during emergencies.

In commercial and military aviation, PSA-based oxygen systems are increasingly adopted for cabin pressurization. These systems extract oxygen from ambient air at high altitudes, ensuring passenger and crew safety. The U.S. Air Force's F-22 Raptor, uses an advanced PSA-based oxygen generation system (OBOGS) to deliver high-purity oxygen to pilots during high-G maneuvers. NEWTEK's adaptive control systems, which auto-adjust to altitude and temperature variations, could further improve the reliability of applications.

PSA technology is gaining traction in rocket propellant production, particularly for in-situ resource utilization (ISRU) on the Moon and Mars. By extracting oxygen from regolith or atmospheric CO₂, PSA systems could reduce reliance on Earth-based resupply. NASA's Mars Oxygen ISRU Experiment (MOXIE) demonstrated the feasibility of producing oxygen from Martian CO₂ using solid oxide electrolysis, but PSA-based approaches offer advantages in energy efficiency and scalability. NEWTEK's collaboration with European research institutions on ion transport membranes (ITMs) could bridge this gap, combining PSA's adsorption efficiency with ITMs' high-temperature oxygen separation capabilities.

PSA systems consume significantly less energy than cryogenic distillation or electrolysis. A typical PSA oxygen plant operates at 0.5–1.5 kWh/Nm³, compared to 4–6 kWh/Nm³ for electrolysis systems. This efficiency is critical for off-grid aerospace applications, where energy resources are limited.

PSA systems are compact and lightweight, making them ideal for space missions with strict payload constraints. NEWTEK's containerized PSA units, which integrate all components into a single ISO container, can be easily transported and deployed in microgravity environments. In contrast, cryogenic systems require bulky storage tanks and complex refrigeration units, increasing launch costs.

PSA technology's modular design allows for redundant oxygen production, ensuring continuous supply even if individual components fail. NEWTEK's skid-mounted systems can be configured with multiple adsorption columns, enabling seamless switching between units during maintenance. This reliability is particularly crucial for long-duration space missions, where system failure could be catastrophic.

As space missions prioritize sustainability, PSA systems are being integrated with solar and nuclear power. NEWTEK's solar-powered PSA plants, developed in collaboration with German green tech firms, store excess energy in lithium-ion batteries, ensuring continuous oxygen supply for off-grid lunar bases. This synergy aligns with NASA's Artemis program, which aims to establish a sustainable lunar presence by 2028, and similar initiatives focused on renewable energy integration in space infrastructure.

PSA Oxygen Generators could revolutionize ISRU by extracting oxygen from extraterrestrial environments. On Mars, PSA systems could separate oxygen from CO₂-rich atmosphere, while on the Moon, they could extract oxygen from regolith through hydrogen reduction. NEWTEK's partnership with Japanese companies to recycle molecular sieves into construction materials further supports circular economy practices in space, reducing waste and enhancing self-sufficiency for long-term space habitats.

Hybrid PSA-electrolysis systems are emerging as a viable solution for aerospace applications. By using PSA for base-load oxygen supply and electrolysis for peak demand or hydrogen co-production, these systems optimize energy use and reduce water consumption. NEWTEK's pilot projects in sub-Saharan Africa demonstrate this hybrid approach, where solar-powered PSA systems provide oxygen for medical clinics while surplus energy powers electrolyzers for hydrogen storage-a model that can be adapted for space applications requiring dual gas production.

NEWTEK has formed strategic partnerships with aerospace research institutions(CAST, ESA), to develop space-qualified PSA systems. These collaborations focus on radiation-resistant materials, microgravity-compatible designs, and ISRU applications. Joint research with CAST has led to the development of zeolite composites that maintain adsorption efficiency under prolonged radiation exposure, critical for deep-space missions.
