Description
Summary:Green hydrogen is an interesting and sustainable alternative capable of diversifying the energy grid and reducing the dependency on fossil fuels, contributing to decarbonizing the global economy. Despite being widely applied on an industrial scale, hydrogen still faces major challenges, mainly due to the high cost incurred in its production, storage, transport, and the electricity required. Thus, the objective of this study was to evaluate the levelized cost of Hydrogen (LCOH) of offshore wind power and solar photovoltaic energy sources in the state of Bahia located in the northeast of Brazil. The two scenarios were created for a PEM electrolysis plant: 50 MW and 100 MW. As a result, for the LCOH, we got, as a result, 2.28 US$/kg H2 and 2.16 US$/kg H2 for solar PV, and 3.81 US$/kg H2 and 3.57 US$/kg H2 for offshore wind unit in the 50 MW and 100 MW systems, respectively. Despite the lower cost, the intermittency of renewable sources must be considered for the operation of solar PV and wind power plants. Offshore wind plants have the advantage of being installed near the main source for electrolysis – water – and of having a large space available, but with a trade-off on cost. The results show that a hybrid system uniting has the potential to be the most viable strategy.
