Aquion Energy Reveals Second-Gen AHI Battery Technology, 40% Increase In Energy

November 13th, 2014 by James Ayre

Aquion Energy recently revealed the second generation of its Aqueous Hybrid Ion (AHI™) battery and energy storage system technology.

The new second generation of the AHI technology reportedly offers an increase in energy “of up to 40%” — without any increase in the size/weight of the S-Line Battery Stack or the M-Line Battery Module product lines.

“We have been hard at work making the world’s best long duration battery even better. The improved chemistry of the second generation Aqueous Hybrid Ion battery yields more energy, and will deliver more value for our customers,” stated Scott A. Pearson, CEO of Aquion Energy. “We are unveiling the new technology at Solar Power International because Aquion’s unmatched long duration batteries enable optimal self-consumption of distributed solar generation and ease the burden of intermittent renewable energy on the grid. These two applications are the key to unlocking broad adoption of clean solar electricity as a mainstream energy source.”

The new generation of the company’s product lines will see a number of different improvements, with the substantial increase in energy being accomplished through an improved utilization of the primary active material in the AHI cells.

“At shorter four to eight hour discharge rates, systems will experience an energy increase of up to 40%. At longer 20 hour discharge rates the second generation S-Line Battery Stack will see a 24% increase in energy to 2.4 kW-hours, while the new M-Line Battery Module will see a 16% increase, now totaling 25.5 kW-hours.”

Given the improved performance, the batteries are now even better suited towards use in conjunction with renewable energy systems.

So it seems 40 cents kwh is the price. Premium wet lead acid deep cycle are less than half that. Agm maintenance free are around 22cents kwh. Balqon lithium packs are 15 cents kwh. So what gives?

This article is completely useless without discussing the price. For battery storage system, the most important metric is the price per kWh of storage then the lifespan of deep charging cycles. The energy density is just a footnote if at all. Price oh price where art thou?

Since I live completely off the grid I have been trying to buy some of these batteries for several years now now with no results,so for now we can only dream of owning these.

How come none of these stories about batteries ever have prices per kWh or LCOE? This isn’t a prototype, right? It’s being marketed.

  There’s a white paper on their site, talking about a ±0.40 $/kWh LCOE for a hybrid PV/diesel application
  - MarTams
    
    LCOE of 0.40/kWh is horribly expensive. It would be a waste of time and money at this stage. If they can bring the LCOE down to $0.01-$0.03/kWh then that would be good.
    - sault
      
      For remote, off-the-grid locations, $0.40 / kWh is decent. Especially if it means that rural areas in developing countries get the electricity they need to vastly improve their earning potential since their electricity consumption is very low.
      
      You also have to take into account the fact that a diesel generator will break down occasionally, or need maintenance / replacement parts. The PV can supply a lot of the energy into the system, lowering the amount of time a diesel generator is run and therefore, lowering these maintenance costs that are external to the cost of diesel generator electricity.
