Weekend read: Southeast Asian interconnection

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.


Malaysia to grant 4-year PPA extensions to bidders in large-scale solar tender

The Malaysian authorities have revealed that they will extend power purchase agreements from the fourth LSS4 tender for large-scale PV from 21 to 25 years.


The Hydrogen Stream: Ultra-stable platinum-lanthanum for more efficient fuel cells

Tsinghua University researchers have developed a way to combine high-cost platinum and a rare earth element, lanthanum, to serve as a catalyst in fuel cells. Meanwhile, SSAB, LKAB, and Vattenfall have revealed plans to launch industrial production of hydrogen direct reduced sponge iron (H-DRI) by the end of this decade.


In Asean nations it’s all about the solar

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 PV cooler lifespan effectiveness factor

Researchers in Malaysia have defined a new parameter to evaluate solar module cooling techniques based on their lifespan effectiveness. They warned that the proposed methodology should be utilized only with standard test conditions, a temperature of 25 C, and a reference PV system without the cooling system.


Singapore regulator issues fresh appeal for clean power

The Energy Market Authority has already attracted proposals for 1.2 GW of renewable electricity, to be generated in four southeast Asian nations, and wants to raise that figure to 4 GW by 2035.


Wacker falls to fourth in global polysilicon ranking

The German company’s decision to cede market share to Chinese companies producing the material for solar panels, in order to focus on semiconductor-ready, electronic grade product, has seen it slip behind its rivals in terms of production scale.


Malaysia’s water reservoir to host 150 MW floating solar plant

The floating facility will be built by Japan’s Shizen Energy and will sell power under unspecified conditions to local utility Syarikat Air Melaka Bhd (SAMB).


The Hydrogen Stream: Metal foam for low-cost green hydrogen generation

Researchers from Saudi Arabia’s King Abdullah University of Science and Technology have presented the results of a low-cost method of generating carbon-free hydrogen. In other news, Norwegian fuel cell producer Nel ASA said it was ready to increase its electrolyzer production capacity to meet the European Union’s raised ambitions for renewable hydrogen, while oil giant Petronas Eneos announced plans to set up a hydrogen production plant in Indonesia.


Multi-level fin heat sinks for solar module cooling

Developed by Malaysian scientists, the proposed multi-level aluminum fin heat sinks (MLFHS) were found able to reduce the module operating temperature by up to 8.45 degrees Celsius and increase power yield by up to 10.75%. The system cost was estimated at $0.60/W.
