An appropriate current collector (CC) is crucial for harvesting substantial power in a microbial fuel cell (MFC). In the present study, stainless steel (SS) and titanium wires were used as the CCs for both the anode and cathode of MFC-1 and MFC-2, respectively. Tungsten wire (TW) was used as the anode CC in MFC-3, with SS wire as the cathode CC. In MFC-4, TW was used as the cathode CC with SS ...

Abstract Vehicle-grid integration (VGI) describes various approaches to link the electric power system and the transportation system in ways that may benefit both. VGI includes systems that treat plug-in electric vehicles (PEVs) as controllable load with a unidirectional flow of electricity, such as “smart” or “controlled” charging or time-of-use (TOU) pricing. ...

Sediment microbial fuel cells (SMFCs) are bio-electrochemical devices generating electricity from redox gradients occurring across the sediment–water interface. Sediment microbial carbon-capture cell (SMCC), a modified SMFC, uses algae grown in the overlying water of sediment and is considered as a promising system for power generation along with algal cultivation. In this study, the ...

Traditional storage plus solar (PV) applications have involved the coupling of independent storage and PV inverters at an AC bus, or alternatively the use of multi-input hybrid inverters. Here we will examine how a new cost-effective approach of coupling energy storage to existing PV arrays with a DC-to-DC converter can help maximize production and profi ts for existing and new utility-scale ...

Each year, the IEA’s Tracking Clean Energy Progress (TCEP) report examines developments across a range of clean energy sectors and technologies. The TCEP uses benchmarks for 2025 as modelled in Energy Technology Perspectives 2017, as well as the milestones identified in the IEA Technology Roadmaps. Measuring against these benchmarks provides an assessment of whether technologies, energy ...

Sealed lead acid (SLA) batteries have a reputation for being durable when used to support portable electronic devices. They require minimal maintenance and offer leak-proof capabilities. But when used with solar energy systems, the units present issues that can hinder the potential and performance of the machines. For example, general purpose SLA batteries should not be deep cycled, as ...

Introduction Renewable energy offers a hopeful promise to reduce the energy sector’s carbon footprint, but many challenges must be addressed before it can be more extensively integrated into our society. One of the greatest barriers to widespread adoption is quite simply that due to the nature of renewable energy – the fact that it is produced only when solar rays, wind, etc. ...

Abstract Salinity gradient energy can be directly converted into electrical power by using reverse electrodialysis (RED) and other technologies, but reported power densities have been too low for practical applications. Herein, the RED stack performance was improved by using 2,6-dihydroxyanthraquinone and ferrocyanide as redox couples. These electrolytes were then used in a flow battery to ...

Challenge Imagine you’ve found the perfect plot of land and construction has started on your dream home, but in order to turn the lights on it will cost an additional $250,000. That’s exactly what happened to one couple in Marin county in Northern California. When local utility Pacific Gas & Electric quoted an exorbitant price to extend grid power to their new home, the ...

Challenge Located between San Francisco and Sacramento, the City of Benicia is an ideal place for electric vehicle (EV) drivers to stop and charge should their cars be low on range. However, the city’s existing infrastructure took four-to-six hours to fully charge a vehicle. In an effort to provide a better option for commuters, and draw additional visitors to Benicia’s ...

In this post we examine the economics of solar + storage. Specifically, we calculate the value of solar and storage for two commercial buildings in each of three markets: California, New York, and Hawaii. We find solar and storage are strongly synergistic in all three markets. The NPVs of solar + storage investments are greater than the sum of the NPVs of solar investments and storage investments ...

Challenge BMW Technology Group planned to launch a ground-breaking electric vehicle (EV) program called i ChargeForward that would allow individual BMW i3 owners to earn money by participating in demand response (DR) events. However, in order for BMW to participate in Pacific Gas & Electric’s day-ahead and real-time DR markets, it needed to guarantee 100 kilowatts (kW) of demand ...

With the growing season winding down in the northern hemisphere, some growers might be thinking about putting their drones away for winter storage. Drones use lithium polymer (LiPo) batteries which are very powerful and lightweight compared to most other types of batteries, but LiPo batteries also need special care for storage. Follow these tips to get the best performance and life out of your ...

Life seems to be getting more and more uncertain. We are being warned about a Brexit rollercoaster and the oil price, at least in percentage terms, seems to be doing a good impersonation of an elevator; up one minute, down the next. All this uncertainty makes decision-making complex , especially when they concern long-life assets. Against this background I have been thinking about the question of ...
