H2OLL  - Innovative Atmospheric Water Generator

H2OLL vision is to provide an always-on, off grid, robust, affordable and reliable water service.  H2OLL will promotes the poorest 10% of humanity by providing safe drinking water (health, education & equality) and will bridge the gap to the 21th century.  H2OLL will also balance the environmental impact of consumers of bottled water in developed communities.

H2OLL is a spinoff from the Technion (IIT), a new propriety and innovative atmospheric moisture harvesting technology, capable of extracting moisture from the air by an absorption-desorption cycle. The new technology generates year-long pure and safe drinking water supply along with constant low energy requirements at all seasons and in any geographic area and time of the day.

A proof of concept prototype has been built and is currently working at the Technion’s Environmental Technologies Yard, producing water since fall 2019.

The academic spinoff is seeking a first-round investment.

The Problem

Global water crisis
670 million people ~10% of the world population do not have access to safe drinking water.

No water =
no health, no education, no equality!
The UN Sustainable Development Goals (SDGs) represent a conceptual roadway to solve these global challenges, with access to clean water in the base of many of them.

Climate change and urbanization increase water
scarcity, and water contamination.

H2OLL  Vision

H2OLL vision is to provide an always-on, off grid, robust, affordable and reliable water service.

H2OLL promotes the poorest 10% of humanity. Safe water (health, education & equality) will bridge the gap to the 21th century.

H2OLL balances the environmental impact of bottled water consumers in developed communities.


Harvesting air moisture by innovative continuous
liquid desiccant system.

The absorption cycle absorbs moisture from the air
consumes little energy.

The regeneration cycle produces water
Energy is invested only in condensing the vapor into liquid water and not in cooling the whole bulk of the (dry) air, which comprises more than 97% of the moist air.

The Technology is a product of more than 5 years of research at the Technion (IIT)
