H2OLL  - Innovative Atmospheric Water Generator

H2OLL vision is to provide pure drinking water where conventional systems fall short for various reasons.

In the developing world, drinking water is mainly supplied by the private sector, with bottled water becoming the preferred source, globally. This results in expensive drinking water, both financially and environmentally.

H2OLL innovative technology ensures a reliable water service all year long in wide geographic areas, enabling clear benefits both for the company and for the customers.

H2OLL can provide drinking water where the supply is not reliable, the water is contaminated (or suspected to be), people drink track/bottled water, and for both developed and developing communities.

H2OLL is a spinoff from the Technion (IIT), a new proprietary 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

People all over the world (developing and developed) consume unsafe/unhealthy drinking water.

The problem is expected to increase dramatically in the coming years due to Climate change, urbanization and population growth

The world is not ready to invest the necessary funds in conventual water infrastructure.

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)
