A solar off-grid energy system


A solar off-grid energy system

Founding year:2017

Location:The Netherlands

Theme:Sustainable Land Use

SOLHO developed a solar off-grid energy system to power horticultural projects. In 30 years from now, there will be two billion more people living in the so-called sun belt region. Agriculture will have to double food production to sustain the global population, with fewer resources and reduced environmental impact.

No technology exists to achieve this target. SOLHO was founded to bridge this gap: we developed an innovative system called SPRHOUT (Solar-PoweRed Horticultural Off-grid UniT). The SPRHOUT uses sun and available water sources (e.g., sea or sewage) to generate all the streams required to operate a greenhouse facility: electricity, heating/cooling, fresh water and CO2.

The SPRHOUT key features are:

Off-grid, no need for electricity grid or gas network
24/7 operation thanks to unique storage capabilities
90% operational savings compared to current solutions
75% reduction in CO2 emission

We believe SOLHO technology can help the transition towards sustainable food provision, ensuring a safer future for Humanity.
