Are renewable hybrid systems economically viable in Brazil?
Renewable hybrid systems with hydrogen are current economic unviable in Brazil. Green hydrogen produced from curtailment events are current economic not feasible. To produce hydrogen economically viable, the plants should operate above h. The CAPEX should cost less than USD 650/kWe to store hydrogen economically viable.
Are solar and wind hybrid systems viable in Brazil?
The model concludes that the solar and wind hybrid system for hydrogen production and storage is not yet viable in Brazil. In addition, the CAPEX of electrolysers and storage tanks and their operating losses are key points for the deployment of these systems.
How much does it cost to store hydrogen in Brazil?
The CAPEX should cost less than USD 650/kWe to store hydrogen economically viable. It is more profitable trading hydrogen than transforming it back into power. The work aims to verify the economic feasibility of renewable hybrid systems for hydrogen production and storage in the Brazilian electric power sector.
Is hydrogen production possible through a renewable hybrid system?
Some studies, for example, already have demonstrated the feasibility of a levelized cost of hydrogen production through a renewable hybrid system [, , ]. An offshore wind hybrid system associated with hydrogen production only, given 10% curtailment, has shown a levelized cost of hydrogen of EUR 3.77/kg .
How much does a hybrid hydrogen tank cost?
Other premises for the hybrid system are the cost for a high-pressure steel tank at 30 bar, which is around USD 300/Kg and operating costs are estimated at 1.5% of initial CAPEX, having a lifetime of 20 years . Also, it was adopted that the thank size is proportional to the electrolyser hydrogen capacity in kg of hydrogen during 15 h.
Is green hydrogen a sustainable long-term supply option?
In particular, green hydrogen has become one of the most sustainable long-term hydrogen supply options . Green hydrogen is currently recognized as a clean energy carrier [4, 5] produced by electrolysis using electricity from renewables to split water into hydrogen and oxygen [6, 7].
The work aims to verify the economic feasibility of renewable hybrid systems for hydrogen production and storage in the Brazilian electric power sector. The methodology applied is based on economic cost analyses of the two largest wind and solar photovoltaic plants in the country.
