Brunei’s electricity sector is dominated by Natural Gas as the primary source of generation, with diesel being used to power the electric system in the Temburong district. Solar PV contributed less than 1% of the total share of generation in 2019
In 2015, the total primary energy supply (TPES) of the country for both energy sources was 3.26 million tons of oil equivalent (Mtoe) in total, with 3.07 Mtoe or 94.3% from natural gas (Table 3.1). Brunei Darussalam has 922 MW of installed capacity in power generation of public utilities, including a solar photovoltaic (PV) at 1.2 MW.
Considering the Wawasan Brunei 2035 (Ministry of Energy, 2014) renewable energy target of 954,000 MWh by 2035, which corresponds to around 600 MWe (calculated using capacity factor of 0.17, the Asian average), the remaining solar power potential that could be used to produce green hydrogen would be around 3,000 MW.

They are designed with large rotor blades and higher hub heights (>100m) to capture larger amount of energy at same rated power. Brunei’s current installed Solar capacity is 4.63MW, with 60MW additional planned by 2024 and a target to reach 300MW by 2035.
However, a large issue is hydrogen’s high supply cost. This study forecasts hydrogen demand in Brunei Darussalam until 2040. It targets the road transport and power generation sectors, which are energy intensive. So far, hydrogen has not been used in road transport and power generation.
