SolarWood is the technology developed by Innovakeme and is on its way to a hospital in Essuatini, former Swaziland.
Good Shepherd Mission Hospital will receive a new way of producing heat and electricity, using biomass and solar energy.
The solution allows the supply of energy, reliably, in this remote region, besides being more environmentally friendly (less 1350 tons of CO2 per year) and more economical (savings of 10% in the annual bill).
The initial investment is 950 thousand euros and part of the financing (100 thousand euros, which can reach 150 thousand euros) is the responsibility of GoParity, a Portuguese fintech specialized in collaborative investment in sustainable projects. Anyone of legal age can invest in the project starting at 20 euros and profit from an interest rate of 6.15% over eight years.
The innovation of the SolarWood solution is related to the integration of several energy production and storage solutions in four containers. This solution is modular and replicable in other remote areas.
Each unit that constitutes SolarWood has a function: one produces and dries firewood, the other uses biomass to produce heat and electricity in a combined way, the third container produces electricity from solar panels and the last is the storage system and management of the energy produced.
SolarWood has a combined power of 150 kWp (in the photovoltaic plant), the capacity to produce 80 kW of electricity and 160 kW of thermal energy, with the batteries having a capacity of 50 kWh.
The hospital that will receive this technology has an annual electricity consumption of 800 MWh and 300 tons of coal to heat water.
The energy consumed comes from the national grid and is mainly produced by coal plants. In addition to the ecological component, SolarWood guarantees a stable supply so that there are fewer interruptions in operation and that there are no failures, for example, in the middle of a medical procedure.
The project also aims at training local communities, gender equality and improving hospital conditions. The operation will employ at least ten local women for on-site technology maintenance and monitoring and 15% of the profits made by the Special Purpose Vehicle will be directed to the Hospital.
