Energy-Storage Batteries | A Whole New Industry

With the global climate crisis focus upon us, which begins Friday September 20, 2019 with a massive worldwide #ClimateStrike, and continues for a full week of events, the entire globe will be fixated on how we can quickly find and execute the cure and save millions of lives, and in certain regions, entire populations.

ST-SAGA-CovFrnt-72-300This year has seen an unprecedented uptick in the switch to solar energy, with California leading the way.  EV car sales are leaping tall buildings. The increase in clean energy is so significant, that the new big industry mushrooming overnight is that of storing excess clean energy, to be used after the sun goes down, or when supply runs out. There are investors and innovators popping up in many countries, looking to produce the highest quality energy storage batteries — small ones for homeowners, and massive ones known as “utility scale” for corporations, towns, cities, etc.

It would be very smart if fossil fuel communities jumped in quick to seize the opportunity and transition coal and oil workers into clean energy storage careers.

Batteries are very important in enabling energy companies to store the excess energy generated by a sunny or windy day, to then be used at night, or on a very still day, when there’s no strong wind force. Critical requirements for high quality energy storage batteries include the following:

  • Capacity & Power – measured in kilowatt hours (kWh), we should get stackable kind so we can easily increase capacity as need grows
  • Depth of Discharge (DoD) – the amount of the battery that has been used, a battery’s use level has a floor; the higher the DoD (ie 80%), the more the battery can be used before needing to be recharged
  • Round trip efficiency – it takes a certain amount of energy to store energy, so the higher the efficiency, the more energy you’ll receive from your battery; the efficiency rate is measured as a percent, the higher the percent, the higher the efficiency (30% is bad, 80% is good)
  • Battery life & warranty – clean energy storage batteries have a “cycle” of charging and draining; battery life is listed as a specific number of cycles, ie 4,000; a warranty will read something to the effect: 4,000 cycles or 8 years at 65% of it’s capacity… meaning at the end of the warranty the battery will have only lost 35% of it’s initial capacity.
  • Manufacturer – there are no so many different brands that it’s difficult to determine which is the best, so it’s important to compare using the above four critical features
