Rural development through solar and pyrolysis systems: Towards energy sustainability

Abstract: Rural communities require socio-economic development and technologies that lead to the deployment of renewable energy systems. For these reasons, a solar parabolic dish cooker (SPDC), solar PV and fast pyrolysis systems were developed. The fast pyrolysis system is designed to generate biogas and biochar using an average biomass consumption and the generated waste per person per day in rural areas at a feed rate of 0.65 kg. 0.157 kg of biogas (CH4, H2 and CO) was recovered at the given feed rate and 73 % of the produced biogas is expected to be handed over to the feed provider since 27 % was burnt in the pyrolyser furnace. The SPDC utilised both aluminium and silver as the reflector materials and higher efficiency (4.182 %) was achieved using a silver dish reflector. Solar PV cooling from 82 °C to 25 °C was investigated and the findings revealed that 439.12 L of H2O and 0.164 kW are required at an operating cost of $0.571. An efficiency of 45.46–75.41 % for the pyrolysis unit, 60 % for the SPDC and 17 % for the solar PV were recorded. This study also recommends the installation of one pyrolysis system in each rural community and equip each rural household with the developed solar systems.
