[en] Currently, more than 1.3 billion people in the world do not have access to electricity and and 1 billion more have unreliable access. This project moves to the Gambia, a country where slow progress in expanding the grid and energy poverty make it impossible to supply rural areas, being forced to use fossil fuelsunrulyand riskily. In this context, decentralized energy generation seems to represent a transition optiontowards the electrification of the country, starting from the main national activities. A0.25haMoringa oleiferacultivationin Muritabeh, a small town in the Gambia, is an interesting location to implement a self-sufficient generation system, estimating an approximate local consumption of 1263kWh per year. Photovoltaic solar energy isthenselected as the main generation source, with a minimum installed powerof 4.5kW. The alternatives for its auxiliary generation are, on the one hand, the use of lithium batteries, which manages to supply 80% of the consumption with the incorporation of 2kWh on a photovoltaic power of 4.5kW, and, on the other hand, an ORC system usinglocally producedbiomass which, due toits limited production, barely achieves an 87% supply with its support to the photovoltaic system. The local conditions are then evaluated to conclude that for a complete supply it is necessaryeitherto replace the artificial dehydration stepand reduce local consumption, or to incorporate ORC technology on the solar system of 4.5kW of photovoltaic capacity and 2kWh in batteries. In this way, the system achieves a supply of 121% with respect to consumption, stimulatinga hybridization that also allows greater flexibility and proportionality with respect to local production.

Proiektu hau Gambian ezartzen da, non grid-aren hedapenmotelaketa energia pobreziakarazo bat adierazten dutenisolaturiko zonaldeentzat, seguruak ez diren erregaiak erabiltzera derrigortuz. Horren ondorioz, deszentralizaturiko energia distribuzioa Gambiaren elektrifikaziorako trantsiziozko pausuan bihurtu daiteke, herrialdean ohikoenak diren jardueretatik hasita.

Alde batetik litio baterien erabilera, 2kWh-ko edukiera duen bateria 4.5kW-ko potentziadun sistema fotovoltaikoan ezarriz kontsumoaren %80-ko hornidura lortuz. Beste aldetik, bertan sortutako biomasa aprobetxatzeko tenperatura baxuko ORC sistema ezarriz, eguzki-energiarekin bat egin eta %87-ko hornidura lortuz.Bertako baldintzak hartzen dira orduan kontutan eta erabateko hornidura lotzeko artifizialki ezarritako lehorketa etapa ordezkatu egin behar dela edo ORC sistema eta fotovoltaiko-bateria sistema bat egin behar direla ondorioztatu da. Modu honetan, kontsumoarekiko %121-ko ahalmena duen sistema lortu da, flexibilitate eta proportzionaltasun handiagoa errazten dituen sistemaren hibridazioaren bidez.
