Periodic Reporting for period 1 - SAFEWater-SDCW (A Disruptively Novel Approach to Clean and Safe Water Supply to Off-Grid Communities – SAFEWater-SDCW)

Période du rapport: 2023-04-01 au 2024-06-30

Résumé du contexte et des objectifs généraux du projet

SolarDew aims to provide 1 million people with clean drinking water by 2030 via the commercialisation of a disruptive, point of use water purification & desalination technology for off-grid communities, co-financed by the EIC Accelerator Programme and the Innovation Council. By the end of the project, the innovative technology will reach TRL 8, demonstrating the following characteristics:

1. Produce high quality drinking water from biologically, chemically contaminated, brackish or saline sources.
2. Decreasing water price, as scale increases.
3. Low maintenance need, thanks to a proprietary membrane with high fouling resistance.
4. Allowing individual/community production of clean drinking water.

By 2030, with scaling of the technology, SolarDew will address the Green Deal Objectives as well as SDGs: 1, 6, 11 and 12, by reducing:
1. households’ expenditure on drinking water by up to 70%, for communities living in rural and coastal areas.
2. child mortality, resulting from waterborne diseases and long-term effects of chemical contaminants.
3. CO2 emissions, averaging 13,500 tons/year.
4. plastic waste by up to 40 million bottles/year.

Travail effectué depuis le début du projet jusqu’à la fin de la période considérée dans le rapport et principaux résultats atteints jusqu’à présent

During Period 1 of the project, the water purification bag was redesigned to increase its size by 15x. SolarDew also developed a roll to roll production process, making the product suitable for scaling up. The supply chain has been set up with multiple partners to prepare for large-scale production. Intermediary pilots have been prepared in collaboration with SEA Group for Chile and University of Crete and Dedisa for Greece. Partnerships and community building is in process to prepare the basis for commercialisation in the 2 markets.

In addition, a patent was filed with the Dutch Bureau of Intellectual Property for the design of the water purification bag and the hydraulic system.

Progrès au-delà de l’état des connaissances et impact potentiel prévu (y compris l’impact socio-économique et les conséquences sociétales plus larges du projet jusqu’à présent)

The following R&D efforts go beyond the state-of-art:
1. The roll to roll manufacturing of the water purification bag with a complexity and size previously not achieved in the industry
2. The development of a connector system with optimised functionalities in a design that is simple to manufacture and assemble.
3. The overall hydraulic design of the water purification bag, allowing the system to operate under very low pressures (gravity flow only)
4. The translation of the whole design to be optimised for manufacturing.


The next steps for SolarDew are:
1. To fully translate the production steps to a full-scale industrialised manufacturing process with a specialised manufacturing partner.
2. To evaluate the water purification bag in the intermediate pilots in Greece and Chile and receive feedback for further optimisation of the design for the 0 series prior to industrial manufacturing.
3. To further demonstrate the technology with other launching customers for which SolarDew would be interested to connect with customers in government, industry or NGOs, interested to become a partner in SolarDew’s Ambassador program for their country.
