Stationary Electric Generators

Large stationary electrical generators may be fixed to a concrete pad, or to a trailer for rapid deployment. Typically they may be used by first responders or the military to provide “off grid” or emergency power to hospitals, shelters, or government buildings. The US military alone has over 50,000 buildings which require emergency backup power. FEMA and other emergency response agencies have an estimated 6-7,000 large generators in use or on standby at any one time in the United States, with a similar per capita use in Europe.

The critical need for reliable power generation was brought to the forefront October, 2012 when the 705-bed New York University Langone Medical Center lost power and its backup system. In researching the incident, Lawrence Associates estimates that hospitals can lose $1 million per power failure, and that 1:20 hospitals in the United States have an unreliable power backup system.  Electricity failures at hospitals in Louisiana during Hurricane Katrina led to a class-action lawsuit against Memorial Medical Center in New Orleans where at least 34 patients died after the hurricane knocked out power.

A ZED powered generator is well suited to large scale power generation for a number of reasons 1) fuel flexibility 2) quiet operation 3) high power to weight ration 4) high fuel economy 5) low emissions.

Portable Electric Generators

Portable power generators are typically used by off-grid recreational properties, or for first responders to power their equipment while being mobile. This can include tent shelters, temporary kitchens, triage medical centers, communications posts, search & rescue mobile posts, or lighting for aircraft landing.

Many houses in the path of severe weather patterns, such as flooding, tornados, or hurricanes also have backup power generators. It is estimated that the North American market for small portable generators is in excess of $150 million a year.

The military also requires small portable generators to power their equipment during operations.

Vehicle Auxiliary Power Units (APU)

As noted in the “Class 8” section of this web site, there is an estimated market of $800 million a year globally for heavy truck auxiliary power units due to recent anti-idling laws.

Where current APU are powered by small, noisy diesel engines in order to be fueled off of the vehicles main tanks, the ZED APU can also run on diesel, but would be virtually silent in operation. Providing heating, air conditioning, electricity, and being quiet gives a driver the best possible rest environment. With miniscule pollutants as opposed to operating the main tractor engine (or conventional APU), and a calculated average fuel savings of 2.0-2.25 gallons of fuel per hour, the ZED APU is expected to be the new industry standard. Where a conventional Class 8 APU has an expected life of 3-4 years, the ZED APU is expected to have a service life of 6-7 years.

The ZED technology could help eliminate over 16 million tons of carbon dioxide emissions from truck idling in the United States each year. The market penetration for APUs in the United States is about 5% (Bubbosh, 2008) and expected to climb to 80% by 2020. In addition to environmental benefits, current APUs save on average 8% in fuel costs each year, according to the EPA. High upfront costs (approximately $7,000-$9,000 per unit) limit APU penetration.

In case point, Wal-Mart introduced a 10 year goal of doubling the efficiency of its trucking fleet by 2015, the second largest private fleet in the nation. Increasing fleet efficiency to this level will prevent 13 million tons of carbon dioxide emissions (Addison, 2007). One of Wal-Mart’s first steps towards this goal was to purchase and install 7,000 APUs in its long-haul trucks. The company has estimated APUs save $25 million in annual fuel costs, a figure that increased with higher global oil prices.

A ZED powered generator is well suited to the heavy truck APU market for a number of reasons, including  1) fuel flexibility 2) quiet operation 3) high power to weight ration 4) high fuel economy 5) low emissions.

Ship Auxiliary Power Units (APU)

In port, or in an emergency, both cargo and cruise ships have large APU to power ship operations. These units are usually large diesel powered generators installed at a high point above the deck where they are protected from large waves and wind driven salt water. They are very noisy, which is why most passenger boats opt for shore supplied power.

Similar in size and weight to Stationary Power Generators noted previously, these large units are also unreliable and expensive, with a service life span of 5 years or less.  The market is estimated to exceed, including freighters, cruise ships and luxury yachts,  $150 million a year in repeat business.

Ship capable APU can also be deployed on the wharf. As opposed to idling a ships engine for power the fuel savings from a shore based ZED APU would be substantial, as would the reduction in pollution.

Case in point, diesel exhaust—the black smoke emitted by port buses, trucks, trains and ships—is the number one toxic air pollutant in California. Average diesel emissions per square mile in West Oakland, near the Port of Oakland wharves, are more than 90 times greater than average emissions for the rest of California. Western Oakland residents breathe diesel particulate levels that are five times greater than the rest of Oakland. Due to diesel particulate exposure, West Oakland residents have an increased lifetime risk of one extra cancer case for every thousand residents. This is more than five times the cancer risk that residents in other parts of Oakland face from diesel pollution.

A ZED powered generator is well suited to the marine APU market for a number of reasons, including  1) low emissions to save lives and healthcare costs 2) quiet operation 3) high fuel economy and 5) fuel flexibility.

Oil industry Pipeline Pumps

Pipeline transported petroleum requires a pumping station typically every mile. These are fueled by stand-alone pumps which are usually fueled more than once a week with diesel fuel. This requires a tanker truck, driver and road maintenance, as well as source of fuel. There are over 180,000 miles of energy liquid pipelines in the USA alone, and an equal distance in Europe.  The Trans-Siberian pipeline alone is 3,800 miles long.

Given the unique capability of ZED engines to burn any fuel, unlike the high cost of refueling current pumping stations, ZED powered pumps can be fueled by tapping into the pipeline and using the crude oil as fuel. This would eliminate tanker trucks, drivers, and access maintenance, thereby reducing the cost of pumping to a fraction of its current level. The cost of pump service is the greatest cost in the pipeline industry, a cost which can be substantially reduced with ZED powered equipment.

A ZED powered energy liquid pump is well suited to the global petroleum industry for a number of reasons, including 1) elimination of pumping station refueling 2) low emissions to minimize environmental impact 3) quiet operation for wildlife and 4) high operating efficiency.
