Cameroon’s main source of electricity is hydropower. Natural gas and oil make up remaining electricity generation. There is significant untapped potential for solar and wind, particularly in the northern regions. As of 2026 there is no indication that the country is producing green hydrogen from electrolysis of seawater.
Cambodia’s energy policy does not include a program to produce green hydrogen from electrolysis of seawater.
Cape Verde is a ten-island independent archipelago of the coast of West Africa. It relies on imported petroleum products for about 80% of its energy. Renewables account for over 20% of electricity generation, primarily wind and solar. As of 2026 the country’s website has not disclosed a program to produce green hydrogen from electrolysis of seawater.
Bulgaria’s energy sources are nuclear power (over 40% of electricity generation), coal (29%), and a growing share of renewables, primarily solar, hydro, wind, biofuels, and waste. As of 2026 its goal of net-zero power generation by 2050 does not include producing green hydrogen by electrolysis of seawater.
Brunei, officially known as Brunei Darussalam, is a small sultanate of roughly half a million residents located on the northern coast of the island of Borneo. Its two non-contiguous parts are entirely surrounded by the Malaysian state of Sarawak. Brunei also has maritime boundaries based on historical British colonial agreements. Brunei’s energy consumption is primarily driven by its abundant reserves of crude oil and gas, which account for the majority of its total exports and over half its per capita GDP. However, these resources are depleting. To cope, the country has established a 1.2 MW solar power plant and is exploring connections to a trans-Borneo electricity grid. As of 2026 the country does not produce green hydrogen from electrolysis of seawater.
Over 80% of Brazil’s electricity is generated from renewable resources, primarily hydropower. It is also a global leader in biofuels and has major offshore oil reserves. Oil production in 2023 averaged 3.4 million barrels per day. Brazil has established its Energy Transition Acceleration Program, however, despite its abundant irradiance, it does not indicate it is pursuing production of hydrogen by electrolysis of seawater.
White hydrogen has been found in the São Francisco Basin.
