HELIOVAP
Solar driven off-grid freshwater

Freshwater, powered by sunlight.


Advanced photothermal materials for modular, off-grid freshwater generation in marine and remote environments.

Photography needed

Black porous photothermal material in sunlight, at the moment it touches water. Close macro, real sample, no render.

The problem

Water infrastructure does not reach everywhere.


Remote islands, marine operations and emergency environments often lack stable electricity, centralized water networks and professional maintenance capacity.

01

Energy intensive

Conventional desalination often requires continuous electricity and high pressure equipment.

02

Infrastructure heavy

Centralized desalination is difficult to justify for small and distributed applications.

03

Difficult to deploy

Marine and temporary environments require simpler, more adaptable systems.

Laboratory evaporation rate
