Electricity grid comprising multiple mini-grids may be more inefficient with significant transmission losses

Adoption of increasing amount of renewable energy by many countries has introduced significant problems associated with how excess energy generated by renewable sources could be handled. Grid level storage solutions such as lithium-ion batteries provide a certain amount of energy storage for excess renewable energy generated. However, production of renewable energy such as solar and … More Electricity grid comprising multiple mini-grids may be more inefficient with significant transmission losses

Challenges of pricing electricity for homes connected to a central battery with feeds from renewable energy and grid electricity

Consider the case where a high-rise apartment block is connected to a battery that stores energy from solar photovoltaic panels and the electricity grid. Typically, the battery would discharge electricity to homes in the apartment block whether the electricity supply comes from solar panels or the grid. Hence, the scenario opens up serious questions on … More Challenges of pricing electricity for homes connected to a central battery with feeds from renewable energy and grid electricity

Flow batteries could provide for grid level storage

Intermittency in solar and wind power meant that energy storage solutions would need to be used to provide power during times when solar and wind power are not available. However, difficulties exist in using current lithium-ion battery technologies for storing large amount of wind and solar power as grid level storage given problems with scaling. … More Flow batteries could provide for grid level storage

Dangers of ultrafast charging of mobile devices

By their design, mobile devices, especially smartphones are always on, and with today‚Äôs need for high speed data communication via mobile base stations providing 4G data and voice services, energy consumption is significantly higher than feature phones of the previous mobile telecommunications era. Thus, battery capacity and energy consumption became primary points of consideration in … More Dangers of ultrafast charging of mobile devices
