climate action with solvatten

Solvatten Presentation COP21, Paris 2015

tisdag 1 december 15

Most of the everyday challenges for the worlds poor can be linked to energy and water.

What energy efficiency and safe water can do for the worlds poor


• Portable and easy to use• No batteries, just sunlight• Up to 40 litres per day

Provides safe, hot water* (75°C) for a family (5-6 p) on a daily basis. It will serve a family for years. Well kept it will last through childhood.

* Meeting WHO’s guidelines for safe drinking water



The effect of heat and UV-B in Solvatten:

Bacteria ( E.Coli) greater than 7,4 log reduction was observed at all water types at >55°C and with a turbidity of 30 NTU.

Virus ( Rotavirus)>5,3 log-reduction and

Cryptosporidium oocysts > 5,0 log reduction

Safe+hot water


Practical. Durable. Direct

Just add sun.

55°-75°C

10-40 liters per day


“Having clean, heated water at home realizes a fundamental right to live a life in dignity”


Using Solvatten increases the renewable energy share in the world’s energy mix.

Solvatten is an energy efficiencient tool for thermal heating of water and a high quality water treatment technology.

It gives direct socio-economic benefits such as better house hold economy, a higher social status, a better life-situation for women, better health etc.

By letting the trees that would otherwise be used as fuel stay standing, multiple benefits such as increased productivity,reduced soilerosion, improved food supply and capture of CO2 are achieved.

Wells are frequently contaminated


Improved water not good enough


Only 14% of Sub Saharan Africa has access to electricity.


90% of Sub Saharan households rely on traditional fuels for energy


“Pre-heating or cooking directly from Solvatten is faster, cheaper, cleaner than traditional methods”


Why Solvatten?1) Economical 2) Saves time 3) Improves the health of the family


Share value with Solvatten

• Reduced morbidity for children in SubSaharan Africa • Will increase school attendance• Will improve HH economy• 1:26 Social Return of Investment • Solar water heater, add renewables to the energy mix• Value for money: Technology for domestic safe and heated water. 0,001€/liter (>40 liters/day) + Solar water heater, renewables to the energy mix 400-500 Kwh/year


Distribution through rural health posts in Kenya


“To use Solvatten is a step closer to having a mixer tap installed in the house. It will take long before we have clean, piped water and electricity in this community but with Solvatten we manage".


Good water, hygiene practice

With Solvatten the general health of the family improves.

Because it is easier and it feels better to wash in clean, heated water.


The Impact Calculator 2015This is what one Solvatten does in one year

The solar technology reduces the need to heat and boil water by burning firewood or charcoal. This leads to reduced deforestation, reduced burning of solid fuels, and consequently reduced emissions, as well as reduced fuel expenses for the urban poor. One year of using a Solvatten unit saves 6-10 mid-size trees.

High uptake 4 years later

Savings, savings, savings. Solvatten saves energy, time and significant amount of money. Average monthly savings in energy and health expenditure $15-20 per month.


President Obama visits the Royal Institute of Technology (KTH) in Stockholm to see the latest developments in energy solutions, research and innovation.

The inventor of Solvatten, Petra Wadström, was given the opportunity to present the Solvatten Solar Safe Water System and explain how it is used around the world to improve health, empower women and lower CO2 emissions.


+220´000 users in + 20 countries since 2007 and with supporters from all over the world


Capturing 20 MWh of solar energy per year
