Southeast Asian nations are speeding up their plans to transmit renewable energy through a proposed regional power grid, with first trials set for 2022, as the area strives to meet climate change targets, government and company officials said.

Some members of the Association of Southeast Asian Nations (Asean) are also exploring carbon capture storage (CCS) technology to reduce emissions, officials said at this week's Singapore International Energy Week conference. Asean has proposed that 23% of primary energy come from renewable sources by 2025.
