East Timor (Timor-Leste) relies heavily on imported diesel for electricity, with 2022 data showing nearly all power generation came from fossil fuels. The country faces high energy costs and low per capita consumption, though electricity access has improved to over 90% in some areas. A major shift is underway, with construction of a 100-200 MW solar plant planned for 2026 to boost renewable energy.

The government aims for renewables to provide 50% of the energy mix by 2030, with a long-term goal of net-zero emissions by 2050. Studies have identified East Timor as having ideal conditions for green hydrogen production.

As of 2026 East Timor is not producing hydrogen from electrolysis of seawater.
