Does Nepal have a potential for off-river hydro storage?

Nepal has enormous potential for off-river PHES. The Global Pumped Hydro Storage Atlas [42, 43] identifies ~2800 good sites in Nepal with combined storage capacity of 50 TWh (Fig. 6). To put this in perspective, the amount of storage typically required to balance 100% renewable energy in an advanced economy is ~1 day of energy use .

How much hydro storage is needed in Nepal?

The Global Pumped Hydro Storage Atlas [42, 43] identifies ~2800 good sites in Nepal with combined storage capacity of 50 TWh (Fig. 6). To put this in perspective, the amount of storage typically required to balance 100% renewable energy in an advanced economy is ~1 day of energy use . For the 500-TWh goal, this amounts to ~1.5 TWh.

Could hydrogen be used to store and transport energy in Nepal?

Hydrogen production in Nepal is unlikely to be significant. Hydrogen or hydrogen-rich chemicals such as ammonia could be used to store and transport energy in Nepal. However, this is unlikely to occur because the efficiency is very low compared with those of batteries, pumped hydro and thermal storage, which unavoidably translates into high costs.

Can Nepal achieve energy self-sufficiency?

The deep renewable electrification of energy services including transport, heating and industry will allow solar and wind to largely eliminate fossil fuels over the next few decades. This paper demonstrates that Nepal will be able to achieve energy self-sufficiency during the twenty-first century.

How are pumped storage hydropower schemes distributed in Nepal?

Strip distribution of technically viable pumped storage hydropower (PSH) schemes at different elevation bands (EB1: 0–––500 m, EB2: 500–––1000 m, EB3: 1000–––2000 m, EB4: 2000–––3000 m, and EB5: 3000–––5000 m above sea level) across Nepal.
