    If the retrofits will be PbC equipped, that is even more interesting.

    iindelco: I was pleased to see this line on the NS999 page:

    I would love to hear of the PbC being tested in hybrid tractors . . .

    ePower has a website here: http://bit.ly/Wgr3V2
    As you say, their claims appear to be too good to be believed.

    They don't mean standard regenerative braking?

    Interesting that this description of the Xtreme Power mystery batteries is "lead acid-based."

    More on hybrid hydraulics: Here is a start-up company doing truck retrofits using carbon fiber hydraulic accumulators.

    "At $19,995 for the hybrid retrofit, it provides a 2-3 year payback for stop-and-go drive cycles based on fuel and brake savings.

    Although electric hybrids are well proven, electric hybrid technology is limited in several ways:

    Cost.

    The cost of second generation batteries that can charge faster, go farther, and last longer are currently prohibitively expensive, ranging from $10,000 to over $40,000. Many battery systems are rated at 500 cycles—or about 18 months of daily charging before replacement is necessary. Equivalent hydraulic pump/motor and tanks cost $2,500.

    Charge time.

    Charge time not only impacts overall efficiency and utilization, but also how efficient the brake regeneration system is. Toyota currently estimates their brake regeneration system at 30 percent efficiency, while hydraulic brake energy regeneration efficiency is over 80 percent, since hydraulics are not limited by battery charge limits during the regeneration cycle.

    Battery Weight.

    Weight has a dramatic impact on overall transportation efficiency, and even lithium ion battery technologies add significant weight, ranging from 350 to well over 1,000 pounds. Equivalent storage in carbon fiber tanks weigh 75 pounds.

    Maintenance talent availability.

    Electric hybrid vehicles are highly complex and the DC power can be dangerous if not handled by specifically trained mechanics. There are not a large number of specifically trained mechanics in the US today, and the training requirements are significant. Most fleet mechanics already have training and a strong comfort level with hydraulic technology.

    Thanks guys. Iindelco, I'd forgotten about ultracaps for a moment.
    But thats why I own MXWL.

    Yes, the hybrid system in the article is a series system from Parker Hannifan called RunWise. It is in garbage trucks in Miami and elsewhere and they are reporting almost 50% fuel savings. The other exciting part is the savings over lithium ion battery storage in initial expense. It may pay for itself in as little as 3 years.

    Eaton also has a hydraulic hybrid system for garbage trucks. I'm interested in investing in hybrid hydraulics but both Parker and Eaton are huge companies with minimal exposure.

    I found this from Pike Research in 2010: "Hydraulic hybrids will play a role in the marketplace, but Pike Research anticipates that this role will be with the bigger trucks, Class 6, 7, and 8 in specific niches. Hydraulic hybrids are also likely to be limited to some degree by job a truck does. For example, a hybrid electric refrigerated truck can run the compressors for the refrigerated box off battery electricity, reducing idle time, but can’t do the same with hydraulic systems. As a result, the hydraulic hybrids are likely to grow within specific niches (garbage trucks, inner-city delivery trucks, shuttle buses), but will likely find difficulty breaking out of those niches."

    I'm with D-inv. The wired.com article cites 25% braking energy recovery for the best batteries (presumably L-ion). Can anyone provide an educated guess on how much of that energy a PbC string would capture?

    Wired.com article on hydraulic hybrids that should interest those interested in regen braking and heavy hybrids.

    http://bit.ly/SC0ZEw

    “The best diesel-electric hybrid can only recover 25 percent of the braking energy. The limitations are that you just can’t charge the batteries fast enough to take all the potential energy that’s available in a braking event. You can charge them at maximum rate and the rest of the energy goes out as heat.”

    In some applications, such as a city bus that is constantly slowing and accelerating, a hydraulic system allows for greater, and faster, accumulation of energy.

    “With hydraulic, we’re able to recover 75 percent of the braking energy to be utilized for the next launch event,” Smith said. . . .

    Consider that the average city bus travels 37,000 miles per year. That means the average hydraulic hybrid would save more than 5,800 gallons of diesel fuel each year over a conventional diesel. By comparison, a Toyota Prius saves about 240 gallons of gas over a conventional Camry.

    Measured across a fleet of buses, that’s a tremendous savings for cash-strapped transit authorities, which generally rely upon federal assistance to buy vehicles. Altair’s design is expected to have a slightly higher up-front cost over conventional diesels but will cost more than $100,000 less than a diesel-electric. Plus, hydraulic hybrids don’t require anything a typical bus barn or fleet manager doesn’t already have in terms of tools or training.

    Those with an interest in marine vessel hybridization may be interested to note that BAE Systems touts a hybrid propulsion system for yachts, tugs, barges, workboats and other ships and boats.

    There seems to be reason to believe that AXPW has major cost savings to offer the hybrid bus market.

    I read in a trade mag that the US is ahead of Europe when it comes to hybrid transit buses. Its interesting that in the US supercapacitors have not caught on. There are two major hybrid bus suppliers, Allison Transmission and BAE Systems. Both have nice web pages.

    http://bit.ly/P0V5HE
    http://bit.ly/P0V5HH

    BAE is using A123 Nano-iron-phosphate and Allison is using the latest Nickel Metal Hydride battery cell technology from PEVE. I believe its the same stuff as found in a traditional Prius battery. Allison is the market leader.

    So lithium and nickel-metal hydride have a major head start. Interesting though that BAE's product was on the road already in the late 90's, and the first generation used lead-acid batteries. AXPW should be offering batteries to them for testing.

    These mainstream hybrid buses cost about 50% again more than a clean diesel bus. The payback period on upfront investment is by my estimation around 15 years. So they still are the exception rather than the rule. Durability is good and they require substantially less maintenance along with a smoother ride, less noise pollution, cleaner air, CO2 reductions etc.

    Advanced Batteries for Utility Scale Energy Storage from Pike Research
    http://bit.ly/QvfKXN
    Under Key Industry Players, Advanced Lead Acid, the table of contents lists only Xtreme Power

    Given the fires in Hawaii, I'm hoping the bio-carbon PbC does not get lumped together with Xtreme Power in anyone's mind. (On the other hand, Xtreme Power has been a definite leader in utility-scale grid storage, something Axion cannot say.)
