AWH – Ultrapure Water (UPW) Feedstock
Enabling Sustainable Feedstock of Ultrapure Water (UPW) Production for Energy Transition and Advanced Manufacturing
Atoco’s AWH Solution
Ultrapure Water (UPW) Challenge
- Clean energy production and advanced manufacturing industries depend on ultrapure water (UPW) as a critical process input
- Key UPW applications include: Green Hydrogen production via electrolysis, Semiconductor manufacturing (rinsing contaminants between nano-scale production steps), and Pharmaceutical manufacturing (drug production and medical device fabrication)
- UPW purity requirements are extreme – contaminants measured in parts-per-billion (ppb) or parts-per-trillion (ppt) level with resistivity exceeding 18 MΩ⋅cm
- Producing UPW can require up to 3.3 times more raw water input, including groundwater, surface water, or seawater, than the final UPW volume
- This makes these sectors among the most resource-intensive industries – and many facilities are sited in arid or water-stressed regions, where competing for scarce water against local communities and other users is emerging as a permitting and reputational risk
Our Solutions
- Atoco harvests water directly from air, already of distilled-water-quality, requiring far less water treatment to reach ultrapure water (UPW) standards than conventional water sources do
- Atoco’s On-grid AWH technology delivers industry-leading energy efficiency, even in harsh environments with ultra-low humidity
- Atoco’s Off-grid AWH technology transforms ultra-low-grade waste heat from hydrogen electrolyzers or manufacturing processes into pure water, with no dependence on external electricity or grid power: The only truly off-grid technology
- Atoco is built to scale to utility-scale Atmospheric Water Harvesting plants, combining low-grade waste heat with nano-engineered reticular materials to produce hundreds of thousands of liters of pure water daily
- Atoco’s AWH technology enables decentralized and sustainable water production, delivering water and climate resiliency to green hydrogen, semiconductor, and other advanced manufacturing sectors.

On-Grid vs. Off-Grid Technology?
Which technology is more suitable for ultrapure water (UPW) production?
Both On-grid and Off-grid AWH technologies can help ultrapure water (UPW) production become water independent and resilient, with each providing distinct and unique advantages and benefits.
On-grid AWH system is a plug-and-play solution with up to 4,000 L/day/unit capacity and industry leading energy efficiency.
Off-gird AWH system is powered 100% by low-grade waste heat from the electrolyzer or manufacturing processes and requires zero external electricity or grid, with up to 1,000L/day/unit capacity.
What if I have enough electricity and need to generate more water?
Atoco’s On-grid AWH system is a plug-and-play solution with up to 4,000 L/day/unit capacity and industry leading energy efficiency, and can be deployed to anywhere with 3-phase power and rigid flat surface to install.
The system is modular which can be stacked as many as you wish to maximize the water generation capacity.

How can I utilize the low-grade waste heat from my electrolyzer or manufacturing processes?
Atoco’s Off-gird AWH system can generate water 100% powered by low-grade waste heat from electrolyzer or manufacturing processes. It is the only technology in the market that can harvest water from air without any external electricity or grid. (100% off-grid)
By transforming the low-grade waste heat into valuable pure water, Atoco’s AWH system provides supplementary cooling to this waste heat stream, reducing the thermal load on the existing cooling infrastructure, which leads to significant energy savings.
The system is modular which can be stacked as many as you wish to maximize the water generation capacity.

Where can I use the water from Atoco’s AWH system?
Atoco’s AWH technology generates pure, distilled-water-quality, water with high flexibility and versatility. Water can be used as a feedstock for ultrapure water (UPW) production which will only require much less water treatment.
If the end-user plans to utilize water for different purposes, additional integration of their own solutions/equipment to mineralize, store and transport will be required.
Is there a different method to achieve more water generation from Atoco’s AWH?
Atoco’s both On-grid and Off-grid AWH systems are modular which can be installed and stacked as many as you wish in a given footprint to maximize the water generation capacity.
More importantly, if you have a stable low-grade waste heat available on-site, Atoco can build an Off-grid Utility-Scale Water Harvesting Station with hundreds of thousands of liters per day capacity.
