Indonesia

Scientists in Indonesia have developed a vacuum technique to lower the temperature of PV modules below the ambient air temperature. They applied it to a solar module in a casing that is resistant to negative pressure.

PlasticBean, a manufacturer of recycled plastic pellets, has agreed to work with EDPR Sunseap to use 100% recycled plastic in floating PV solar projects in Indonesia, Singapore and South Korea.

A group of German companies plans to set up a 500 MW electrolyzer for a 1 GW green hydrogen project in the North Sea. US scientists, meanwhile, have engineered a light-activated nanomaterial to convert ammonia into hydrogen, and Canadian researchers have unveiled a new way to structure catalysts for fuel cells.

Sun Cable plans to develop the world’s biggest intercontinental solar and storage project, and has signed a deal with the Indonesian government that could unlock more than AUD 170 billion ($115 billion) in renewable energy generation and transmission operations across the archipelago.

Australian independent power producer ReNu Energy has signed a deal with the developers of a proposed 3.5 GW solar-plus-storage facility in Indonesia to explore the potential large-scale production of green hydrogen for supply into Southeast Asia and beyond.

Masdar says Africa’s annual hydrogen exports could hit 40 million tons by 2050, while Israeli researchers have published a new study on the discharge characteristics of oxidized intermediates formed under water photo-oxidation conditions.

The International Renewable Energy Agency (IRENA) says that solar could become the backbone of Indonesia’s energy system by 2030. However, the nation’s own expectations are still far off from IRENA’s scenarios.

While near neighbors, the electricity generation of the countries of Southeast Asia couldn’t be further apart. Indonesia burns locally mined coal; Malaysia has reserves of oil and gas; and populous Singapore, Vietnam, and the Philippines depend on fossil fuel imports. They could all benefit from increased solar electricity but higher grid capacities and interconnection are key for an opportunity to unlock the power of the sun.

Indonesia will have to get to work installing more than 24 GW of solar this year – and every year – if the region is to achieve the 2.1 TW to 2.4 TW of photovoltaics Irena has estimated it will require to achieve a net zero carbon energy system by 2050.

The aerator consists of a 200 W solar panel, an aerator frame, an eight-leaf windmill for paddling water and restoring oxygen levels, a DC motor working as a driving wheel, a buoy as a component lifter, and a box panel as a protective tool that uses the electricity network.
