A New Home Battery: The Nissan xStorage

What? In May 2016, Nissan unveiled its entry in the home battery market, the xStorage. Unlike the Tesla and Mercedes residential batteries, Nissan's re-uses old electric vehicle batteries, making the xStorage more environmentally friendly. At an approximate cost of U.S. $4,500, including installation, the unit holds 4.2 kWh of electricity and is more expensive than the Tesla Powerwall, which holds 7kWh and costs U.S. $3000. The xStorage enables users to draw and store electricity from the grid during off-peak hours, and to connect to residential renewable energy sources. Nissan is also developing a vehicle-to-grid system, that will enable electric vehicle owners to charge their car at home. 

So what? The Nissan home battery is one more example of how electricity storage technologies are creating an increasingly complex and distributed electricity market. Nissan's vision for the future of the domestic electricity market is based on individual ownership of parts of the system.  Grid electricity price fluctuations may be an important driver for the sale of the xStorage, though in jurisdictions like Quebec, where electricity prices are the same all day, there is no economic incentive for this technology. With more automakers offering residential battery storage, this could affect petroleum-related infrastructure in North America, including gas stations. Presently, electric vehicle owners have "range anxiety", concern about how far they can travel on a charge. Owners of internal combustion engine vehicles may have petroleum anxiety as they worry about finding gas station.
