  • Photovoltaics for metro stations

    Bangladeshi researchers have modeled the technical and economic potential of integrating rooftop solar PV across Dhaka Metro Rail's MRT Line 6, finding that a 20.38 MW system distributed across 21 sites could significantly offset auxiliary electricity demand while delivering strong financial returns. The system generates more than 25.5 GWh annually, avoids approximately 235,297 tonnes of CO2 emissions over 20 years, and has a six-year payback period, 234.1% return on investment, and a net present value of $20.05 million. The study, the first to pair detailed station-level PV design with zone-based hybrid optimization for a South Asian metro system, divided the city into three zones for localized system design, with Zone B being the most cost-effective and Zone C achieving a 70% renewable fraction without battery storage. Multiple universities in Bangladesh contributed to the research published in Energy Reports, highlighting the importance of grid sellback tariffs and solar irradiance in determining the optimal system architecture.

  • Energy Forum Signals Asia’s Clean Energy Transition Is Entering A New, High-Stakes Phase

    The Asia Clean Energy Forum 2026 in Manila highlighted the region's energy challenges, including geopolitical tensions affecting fuel markets and millions of people lacking reliable power access. The forum emphasized the shift towards clean energy transition in Asia, with a focus on building secure, resilient, inclusive, and intelligent energy systems. Discussions at the forum included the potential of offshore wind in the Philippines, the need for grid modernization to support renewable energy deployment, and the cautious return of nuclear energy to the regional conversation. ADB President emphasized the importance of building interconnected power systems to strengthen energy security in the region. The section also discusses the role of nuclear energy in long-term energy security, the Pan-Asia Power Grid Initiative to connect national grids for clean energy trade, and the shift towards cross-border power trade for resilience and affordability in Asia. The focus on AI-driven grid management, decentralized energy systems, and electric vehicles as grid assets highlights the importance of software in ensuring the success of renewable-heavy grids. The conversation around EVs in Southeast Asia has shifted towards their role in stabilizing the grid, rather than just as a decarbonization tool, due to the region's rising vehicle ownership. Charging infrastructure was also highlighted as a key component in this shift. The article emphasizes the interconnected nature of EVs and intelligent grid management as part of the broader transition to clean energy in Asia. The region is on the brink of transformation, with the need for smarter systems, stronger grids, and deeper cooperation to navigate the complexities of the energy transition.
