  • 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.

  • Electric School Buses Put Batteries To Work To Stabilize Grids

    Electric school buses with bi-directional charging technology, known as vehicle-to-grid (V2G) capability, are being used to help stabilize the electrical grid during peak demand periods. There are over 6,700 electric school buses deployed in the US, with some batteries exceeding 200 kilowatt-hours. These buses can charge during low demand times and send power back to the grid when demand is high. California is leading the way in V2G school bus technology, with projects in Oakland and San Francisco expected to generate significant amounts of electricity annually. Several states and organizations are investing in V2G infrastructure programs, with partnerships with major utilities like PG&E and Southern California Edison, aiming to utilize electric buses as generators during emergencies and disasters for climate resilience efforts. Regulatory frameworks and standards for V2G technology are still in the early stages.

  • Powering fertilizer production with agrivoltaics

    India's fertilizer sector faces vulnerability due to reliance on imported natural gas for urea production, leading to increased subsidies for farmers. To address this, an integrated system combining agrivoltaics, maize cultivation, ethanol production, and urea manufacturing is proposed, utilizing captured CO2 for low-carbon urea production and green hydrogen for ammonia synthesis. This model offers multiple revenue streams, including government blending targets for ethanol and carbon markets for emission reductions, benefiting farmers, industry, and the government while supporting rural economic development. The Renewables team at CSTEP, a research-based think tank focused on science, technology, and policy, leads the way in promoting renewable energy solutions and energy conservation strategies in India.
