  • global analysis of the techno economic potential of renewable energy hybrid systems on small islands
    Energy Policy, 2016
    Co-Authors: Philipp Blechinger, Catherina Cader, Paul Bertheau, H Huyskens, R Seguin, Christian Breyer
    Abstract:

    Globally, small islands below 100,000 inhabitants represent a large number of diesel based Mini-Grids. With volatile fossil fuel costs which are most likely to increase in the long-run and competitive renewable energy technologies the introduction of such sustainable power generation system seems a viable and environmental friendly option. Nevertheless the implementation of renewable energies on small islands is quite low based on high transaction costs and missing knowledge according to the market potential.

    Abstract:

Nevertheless the implementation of renewable energies on small islands is quite low based on high transaction costs and missing knowledge according to the market potential. Our work provides a global overview on the small island landscape showing the respective population, economic activity, energy demand, and fuel costs for almost 1800 islands with approximately 20 million inhabitants currently supplied by 15 GW of diesel plants. Based on these parameters a detailed techno-economic assessment of the potential integration of solar PV, wind power, and battery storage into the power supply system was performed for each island. The focus on solar and wind was set due to the lack of data on hydro and geothermal potential for a global island study. It revealed that almost 7.5 GW of photovoltaic and 14 GW of wind power could be economically installed and operated on these islands reducing the GHG-emissions and fuel consumption by approximately 50%. In total numbers more than 20 million tons of GHG emissions can be reduced by avoiding the burning of 7.8 billion liters of diesel per year. Cost savings of around 9 USDct/kWh occur on average by implementing these capacities combined with 5.8 GWh of battery storage. This detailed techno-economic evaluation of renewable energies enables policy makers and investors to facilitate the implementation of clean energy supply systems on small islands. To accelerate the implementation of this enormous potential we give specific policy recommendations such as the introduction of proper regulations.

  • kpi for solar pv diesel hybrid mini grids in remote islands of bangladesh
    Energy Procedia, 2016
    Co-Authors: Dipta Majumder, Junaed Tazdik, Kazi Ahsan Uddin, Md Abdullah Al Matin
    Abstract:

    Abstract Solar Photovoltaic (PV)-Diesel based hybrid mini grids are getting popular in Bangladesh in order to electrify remote rural areas i.e. islands. Grid quality electricity is provided to the poor people through these mini grids. Due to the high initial investment and associated risks, financial viability of the mini grids depends largely on the performance of the plant. Hence, a Key Performance Indicator (KPI) model is proposed for a mini grid to identify the overall performance of the plant. A mini grid project at Paratoli, Narsingdi, Bangladesh has been taken as a case study to validate the KPI model. Analysis from the data based on the KPI has also been done.

  • energy return on investment eroi of mini hydro and solar pv systems designed for a mini grid
    Renewable Energy, 2016
    Co-Authors: Noah Kittner, Shabbir H Gheewala, Daniel M Kammen
    Abstract:

    With dramatic cost declines and performance improvements, both mini-hydropower and solar photovoltaics (PV) now serve as core options to meet the growing demand for electricity in underserved regions worldwide. We compare the net energy return on energy invested (EROI) of mini-hydropower and solar electricity using five existing mini-hydropower installations in northern Thailand with grid-connected solar PV simulations. Both assessments use a life cycle perspective to estimate the EROI. We find that distributed Mini-Grids with penetrations of solar PV up to 50% of annual generation can exceed the EROI of some fossil-based traditional centralized grid systems. The analysis will help planners and engineers optimize Mini-Grids for energy payback and utilize local resources in their design. The results suggest higher EROI ratios for mini-hydropower plants than solar PV, though mini-hydropower plants typically yield lower EROI ratios than their large-scale hydropower counterparts.

  • energy access and sustainable development
    PHYSICS OF SUSTAINABLE ENERGY III (PSE III): Using Energy Efficiently and Producing It Renewably, 2015
    Co-Authors: Daniel M Kammen, Peter Alstone, Dimitry Gershenson
    Abstract:

    With 1.4 billion people lacking electricity to light their homes and provide other basic services, or to conduct business, and all of humanity (and particularly the poor) are in need of a decarbonized energy system can close the energy access gap and protect the global climate system. With particular focus on addressing the energy needs of the underserved, we present an analytical framework informed by historical trends and contemporary technological, social, and institutional conditions that clarifies the heterogeneous continuum of centralized on-grid electricity, autonomous mini- or community grids, and distributed, individual energy services. We find that the current day is a unique moment of innovation in decentralized energy networks based on super-efficient end-use technology and low-cost photovoltaics, supported by rapidly spreading information technology, particularly mobile phones. Collectively these disruptive technology systems could rapidly increase energy access, contributing to meeting the M...

  • Driving rural energy access: a second-life application for electric-vehicle batteries
    Environmental Research Letters, 2014
    Co-Authors: Hanjiro Ambrose, Dimitry Gershenson, Alexander Gershenson, Daniel M Kammen
    Abstract:

    Building rural energy infrastructure in developing countries remains a significant financial, policy and technological challenge. The growth of the electric vehicle (EV) industry will rapidly expand the resource of partially degraded, ‘retired’, but still usable batteries in 2016 and beyond. These batteries can become the storage hubs for community-scale grids in the developing world. We model the resource and performance potential and the technological and economic aspects of the utilization of retired EV batteries in rural and decentralized mini- and micro-grids. We develop and explore four economic scenarios across three battery chemistries to examine the impacts on transport and recycling logistics. We find that EVs sold through 2020 will produce 120–549 GWh in retired storage potential by 2028. Outlining two use scenarios for decentralized systems, we discuss the possible impacts on global electrification rates. We find that used EV batteries can provide a cost-effective and lower environmental impact alternative to existing lead-acid storage systems in these applications.
