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.
Botswana is a landlocked country. It cannot produce green hydrogen by electrolysis of seawater.
Bosnia & Herzegovina is a landlocked country. As such, it cannot produce green hydrogen by electrolysis of seawater.
Bolivia is a landlocked country, unable to produce green hydrogen from electrolysis of seawater.
Bhutan is a landlocked country in the Himalayan Mountains, north of Bangladesh. As such, it cannot produce green hydrogen by electrolysis of seawater.
Benin is transitioning from imported fossil fuels (over 98% of power, mostly from Nigeria and Ghana) toward solar and hydro. Only about 36% of the population had electricity access in 2022, with rural areas as low as 10%. As of 2026, Benin is trying to reach energy independence by 2050. It has recently enacted a National Renewable Energy Development Policy. Presently Benin is not producing hydrogen by electrolysis of seawater.
Belize relies on 30% to 50% of electricity imported from Mexico. Local generation is high in renewables, approximately 53% in 2022 from hydro and biomass. In 2025 Belize launched a Special Electricity Committee to develop a National Electrical Energy Mix Master Plan to diversify Belize’s energy sources. As of 2026 Belize does not produce green hydrogen from electrolysis of seawater.
As of 2024, nuclear energy contributes approximately 40% of electric generation, followed by natural gas (18%), wind (18%), and solar (11%). The country has no infrastructure to produce green hydrogen from electrolysis of seawater.
