Cold thermal storage crucial to boosting liquid-air energy storage efficiency
Researchers reviewed 110 studies on cold thermal energy storage in liquid-air energy storage, finding that cold storage performance has a far greater impact on system efficiency than previously assumed. While phase change materials offer high theoretical efficiency gains, simpler packed-bed sensible heat systems are currently the most mature and cost-effective option, with further experimental validation needed to bridge the gap to large-scale deployment.
Singapore raises 2030 solar target to 3 GW
Singapore has increased its 2030 solar target by 1 GW after surpassing the original 2 GW goal before the end of last year.
SERIS builds 22.1%-efficient perovskite-silicon tandem solar cell based on double-sided polysilicon layers
SERIS researchers developed a 16-cm² perovskite-silicon tandem solar cell with a double-sided TOPCon bottom cell, enhancing passivation, reducing recombination, and increasing voltage and fill factor.
Aiko, Maxeon settle global back-contact patent dispute
Under the terms of the agreement, Aiko will be licensed to Maxeon’s back-contact solar cell and module patents outside the U.S., while both companies drop all ongoing legal actions.
Singapore forecast to reach 5.3 GW of solar by 2035
UK consultants GlobalData say Singapore could add between 300 MW and 400 MW of solar annually through to 2035, taking cumulative capacity from around 1.9 GW today to the 5 GW threshold.
Singapore team develops durable perovskite-silicon tandem solar cells
National University of Singapore scientists claim that vapor-deposited perovskite-silicon tandem solar cells built on industrial silicon wafers achieve both high efficiency and long-term thermal stability, addressing a central barrier to commercial deployment.
NTU achieves high stability in 25.1%-efficient inverted perovskite solar cell
Researchers at Nanyang Technological University have demonstrated a method to integrate chemically inert low-dimensional interface materials into the fabrication of inverted perovskite solar cells. Their prototype solar cells retained over 93% of the initial power conversion efficiency of 25.1% after 1,000 hours of operation, and 98% after 1,100 hours at 85 C.
Singapore, China to supply solar-plus-storage power from Indonesia
Singapore’s Equator Renewables Asia (ERA) and China’s CRE International Co. Ltd (CREI) will jointly develop a 900 MW solar and 1.2 GWh battery project in Indonesia, with 400 MW (AC) slated for export to Singapore.
Singapore approves 1 GW hydropower import project from Malaysia
Singapore has conditionally approved a 1 GW hydropower import project from Malaysia’s Sarawak state, with first deliveries expected around 2035.
Solar and wind integration crucial as Southeast Asia electricity demand grows
The International Energy Agency’s latest report says solar and wind energy are well placed to meet Southeast Asia’s growing electricity demand. It adds that while additional deployment will create flexibility challenges, most countries in the region can integrate more solar and wind energy without requiring major system changes.
