FAQs

Q?What kinds of things does HEC do to make their gensets able to work 24/7?
A.

The generators we use are purchased from a company in Italy, which we consider to be the best in the world. These generators should operate faultlessly without any maintenance for 20 years or more. We rebuild proven Ford 4.9L and 7.5L engines making  over 30 improvements and also manufacture new engines modeled after these engines which have decades of proven performance in the industrial marketplace.

Q?Do you only work with customers in the U.S.?
A.

We work with potential customers in any place in the free world where shipping of our gensets is not restricted by the U.S. government.

Q?What kind of terms should be expected?
A.

On smaller orders, we need to have advance payment of the purchase price.  With larger orders, a minimum of 50% is expected with the P.O., with 25% in 45 days, and the balance upon shipping.

Q?What kinds of ordering intervals can we expect?
A.

Typically, it takes from 14-16 weeks depending upon the number of gensets and the complexity of the order, before shipment can be made.  Shorter intervals may be possible if the genset or components are in inventory.

Q?What do you do to make your gensets able to operate 24/7?
A.

We use engines patterned after proven engines, with decades of proven performance in the industrial marketplace.  In addition, we make over 30 improvements to make these engines even more durable and efficient, so they are proven to operate 24/7.

Q?What electronic controls do we use?
A.

With a genset, we generally provide two electronic controllers.  The first is our proprietary system, Oxx Boxx, which we build to control our engines.  In addition, we purchase and install a specialized, proven, control system, Deep Sea, which balances the engine and generator with the electronic grid.  These controllers work together in providing seamless electric power.

Q?What are the pressure requirements of fuels in your gensets?
A.

Wherever possible we use electronic fuel injection in our systems.  Generally we like to have a minimum of 25-30 psi. This does not mean we cannot accommodate lower pressure levels.  In some cases we can naturally aspirate our engines, which does not require a special pressure level.

Q?What are the maintenance costs of your gensets?
A.

The generators we use are very reliable; there should be no maintenance costs for twenty years.  Generally, 2% of the fuel costs is a good cost for maintenance.  HEC takes special measures to condition their gensets so they are extra durable and able to operate 24/7.

Q?What are safety considerations with using various fuels?
A.

All fuels are dangerous.  Hydrogen, anhydrous ammonia, gasoline, propane, and natural gas are not exceptions.  With each fuel, safety must be considered first.

Q?Does HEC provide the fuel?
A.

Many potential customers call us and want to go to hydrogen or another fuel without totally understanding the depth of what they are considering.  The customer needs to provide the fuel.  For instance, unless the client has the hydrogen fuel, it normally does not make economic sense to call us and ask for both the gensets and the fuel.  Having said that, we are working on methods of providing fuels at reasonable prices.

Q?What does N+1 mean?
A.

What “N” means is the number of gensets necessary to produce the needed amount of power.  For instance, if we were providing one megawatt of power, we would use five, 200 kW gensets,.  The “+1” means adding an additional genset, to allow for service and extra down-time in case of emergency.  In our example, we would use 6 gensets rather than 5.  It gives the system an added safety factor.

Q?What is the maximum amount of power you can produce?
A.

Theoretically, there isn’t a maximum limit.  However, from a realistic point of view we can produce up to 5-10 megawatts.   Above this level other options should be considered.

Q?What are the weights and dimensions of your systems?
A.

Our basic genset is approximately 4 ft wide by 8 ft long, by 6 ft high.  A single 9.4L genset, with 360 kVA genset, can weigh up to approximately 4000 lbs.

Q?How much does it cost to purchase one of your gensets?
A.

This is a question that is not easily answered.  It depends a lot upon the variables, such as the make-up of the gas that is going to be used, the environment that genset will be operating, and the btu-value of the gas.  Typically our prices vary from $400 to $1100 per kW for the basic system, with additional charges for other options such as  “remote oil”, “total enclosures” or “stainless steel enclosures”.

Q?How much hydrogen does it take to power a certain size genset?
A.

Most people that contact us do not have any idea of how much hydrogen gas it takes to power our gensets.  Even with our high-efficiency gensets it still takes 2/3’s of a cubic foot of hydrogen gas per kW, per minute.  In other words, it takes approximately 66 ft3 of hydrogen gas per minute to power a 100 kW genset.

Q?Do the gases you use have to be 100% pure?
A.

One of the advantages that ICE’s have over fuel cells is that we can use fuels that are not pure.  An ICE can operate on a less-pure fuel and is much more forgiving than a fuel cell.

Q?What types of fuels can you use?
A.

HEC specializes in using “alternative fuels” which include hydrogen, natural gas, syn-gas, landfill gas, anhydrous ammonia, natural gas, propane and others. Probably, the only gases we won’t work with are the compression-ignited fuels, such as diesel.

Q?How should I proceed if I need more information?
A.

Proceed to “contact information” and fill out the form with the appropriate question.  We will make every effort to get back to you.

Q?Why should I consider using HEC?
A.

We are a unique, small firm that can help you meet your energy needs. We will come up with options not commonly considered by a larger firm.

Q?Why is hydrogen a great energy resource?
A.

Hydrogen is the most prolific element on the earth.  By weight, hydrogen, has the most energy of any fuel.  Its main benefit is that it can be combusted to produce a lot of energy, producing only heat, nitrogen, and water.  It is considered to be the ultimate fuel.
