Goal 7: Ensure access to affordable, reliable, sustainable and modern energy for all
Off-grid consumers with access to biomass and in a region where the feed-in tariff for providing the grid with renewable energy is high enough to make feeding biomass energy onto the grid profitable email with representative

The PP20 Power Bank is connected to load bank for 20 hours, running on walnut shells for 20 hours in order to evaluation the sustained power output.
The low threshold load test was done with tar testing: to test the gasifier operating temperature as load decreases to make sure the gas is clean. When the load is less than 5kW, the reactor begins to produce more tar because the temperatures aren’t high enough to crack tar so the the threshold has been set at 3kW.email with representative
