Onboard Dynamics Announces Instant Refueling for CNG Fleets

by

Bend, OR. August 12th, 2020 – Onboard Dynamics announces the launch of their new GoFill™ refueling system. It is an instant and nimble drying and dispensing unit for refueling compressed natural gas (CNG) vehicles. The new product eliminates infrastructure barriers for fleet operators who immediately need an easy CNG station setup to refuel their commercial trucks.

The first unit rolled out in Oregon, as part of the NW Natural’s free truck loan program. The GoFill will be providing natural gas for refueling CNG into a Hyliion low-emission Class 8 truck for long and heavy hauls. The program provides fleet operators a short-term, no-cost demo period to experience the vehicle. The on-site, easy station set-up makes fueling convenient during the demo period.

“We designed the GoFill as a companion to the GoFlo® compressor to create a CNG-in-a-day solution,” said Rita Hansen, CEO of Onboard Dynamics. “We’re excited to roll out our new product for NW Natural’s truck loan program and help contribute to the adoption of natural gas vehicles.”

The versatile design makes the GoFill a temporary or permanent installation. When paired with Onboard Dynamics’ natural gas compressor, the GoFlo, an instant fueling station can be set up that doesn’t require electricity to operate. This makes rapid deployment possible in locations where infrastructure is challenging.

“The GoFill is a crucial part of our truck loan program because it gives new natural gas fleet operators easy access to refueling while they test the trucks, and without fueling roadblocks to worry about,” said Chris Kroeker, NW Natural product manager of natural gas vehicles.

The new GoFill, when packaged with the GoFlo compressor, gives operators everything they need to begin converting their fleet to natural or renewable natural gas. It provides an easy-to-setup and take-down CNG fueling station that will create new opportunities for expanding CNG fleets or to quickly provide a fueling station for ad hoc projects.

Onboard Dynamics selected as a semi-finalist in ARPA-E’s $75m scaleup funding opportunity.

by

Onboard Dynamics, Inc. initially spun out of a concept that originated at Oregon State University and was funded by Advanced Research Projects Agency – Energy (ARPA-E) to address the critical lack of infrastructure to refuel natural gas vehicles. The company developed innovative natural gas compression technology allowing a low-pressure natural gas source to be compressed up to 3600 PSI within an engine platform that runs on natural gas to compress natural gas without the need for electricity. 

Their commercialized GoFlo® compressor provides critical, smaller, and more flexible compression solutions for use in the natural gas and renewable natural gas (RNG) industries. Since it does not require electricity, this natural gas-powered system lowers installation and operating costs, facilitates easy mobility and redeployment, and maximizes operating resiliency. In addition, the novel, mobile compressor technology enables natural gas utilities to perform critical pipeline maintenance in their efforts to address methane leakage.

The Untapped Opportunity of Smaller Sources of Methane

The Untapped Opportunity of Smaller Sources of Methane

Most who have studied the challenges of a clean, low-carbon, and economical energy supply system agree that methane, produced either from wells or bio-sources (e.g., dairies, landfills, and water treatment plants), will play essential role in the decades ahead. A key challenge in realizing this opportunity is the fact that many of these diverse  methane supplies are from sources whose production rates are so low that it can be cost-prohibitive to provide two essential steps for commercial use:

  • Cleanup and conditioning of the raw methane mixture from either a well or bio-source. Methane from many important sources can contain various impurities, such as moisture, CO2, nitrogen, H2S, etc. These impurities need to be removed to produce fuel-grade methane that can be transported in a cost effective manner.  A variety of proven technologies exist to remove these impurities, however most are costly at smaller scales.

  • Transportation of clean methane to a viable market. When the volume of methane is large enough and/or the transport distances long enough, pipelines are a cost effective, safe, and clean way to transport methane. But when a pipeline cannot be justified, transportation of methane to market can be problematic due to its low energy density.  Again, numerous non-pipeline options exist, such as compressing the methane into CNG, cooling it into LNG, or converting it into a liquid fuel (such as methanol or dimethyl ether (DME)). Again, the challenge with these processes is their cost at modest scale.

Two examples will illustrate the size of this opportunity if the challenge of scale for cleaning and transport could be resolved:

Dairies

1000 cows can produce 50 to 100 mscf/day of RNG

There are 42,000 dairies in the US, while the RNG Coalition reports that less than 40 dairies produce RNG (renewable natural gas, or clean methane). Current dairy RNG projects will typically have over 10,000 cows, while the average dairy has only 187 cows. A dairy with 1000 cows could produce between 50 and 100 mscf/day of RNG. From these numbers, one can see that there would be an opportunity for thousands of systems to recover RNG from dairy farms alone, if these systems could be made cost effective at smaller scale.

Oil and Gas Wells

In 2017 646,000 mscf/day of methane was vented or flared from oil producing wells.

According to the EIA, at the end of 2017, there were 991,000 producing oil and gas wells in the US. In this same year, 236,000 million scf (646,000 mscf/day) of methane was vented or flared from producing wells, largely because it was not cost effective to clean and transport methane from the smaller and more remote wells. Worldwide venting and flaring has been estimated to be about 4 times greater than in the US, largely due to less stringent environmental laws outside the US.

These numbers suggest that there is both a business opportunity and an environmental need for thousands, if not tens of thousands (depending on the achieved cost), of modest scale systems that can clean and make available for transport distributed sources of geological and bio-derived methane. The companies that develop such systems will see strong success in the coming years. 

Enhancing Fleet Resilience with CNG Vehicles and the GoFlo® Compressor

Many fleet operators are seeking to “green” their fleets to reduce their carbon footprint and to reduce their emissions of regulated pollutants, such as NOX and particulate matter. Operators of emergency vehicles, such as police, fire, ambulance, and certain public utility vehicles, are no different. Having connected with managers of numerous emergency fleets, we learned that these essential vehicles present special challenges for switching from traditional liquid fuels, such as gasoline or diesel to cleaner alternatives.

The fuel challenges of emergency vehicles

Unlike many fleet vehicles, emergency vehicles do not have predictable daily use patterns, especially in terms of miles driven. Some days might require few miles, while other days require many more miles… especially during a major emergency in which such vehicles are most needed. This puts a premium on being able to oversize the fuel tank (including batteries, if an electric vehicle) without significantly increasing cost or refueling time. Traditional liquid fuels score well in this respect, while electric vehicles are poor. Natural gas vehicles (NGV’s) fall between these two extremes.

Another factor in determining the merit of a fuel for an emergency vehicle is ts refueling characteristics. It is hard to match the resilience and reliability afforded by traditional liquid fuels for use during major emergencies. It is not costly to store the required volume of liquid fuel in a simple tank. Furthermore, the energy and power required to transfer a liquid fuel from a storage tank to a vehicle is modest, so that it is reasonable to design a refueling system that does not require grid electrical power (that might not be available).  This pumping power could be provided by a modest standby generator (operating on the stored fuel), batteries, or, even gravity. And such liquid refueling system would conveniently be fast.

Up until now it has been problematic to find an alternative fuel solution for emergency fleets that affords this same combination of qualities as liquid fuel: freedom from uncertain grid electricity and fast refueling with no compromise in vehicle range. The availability of the GoFlo natural gas compressor changes this calculation. It now becomes possible to refuel emergency vehicles quickly simply by connecting to the very reliable natural gas grid. GoFlo is powered by natural gas and, thus, has no need for an electrical power source.

Rita Hansen, CEO of Onboard Dynamics speaking at the Green Transportation Summit & Expo about resilience of emergency fleet vehicles powered by natural gas

Providing resilience to an emergency fleet means storing a certain amount of energy that can be transferred to the vehicles.

Let’s assume that a fleet has determined that it needs an emergency supply of 1000 gallons of gasoline. If their vehicles average 10 mpg, this fleet has 10,000 miles of emergency fuel. If this fleet wanted to provide the same 10,000 miles of stored “fuel” for electric trucks via a central battery, it would require about 5,000 kwh of battery storage (based on trucks that require 0.45 kwh/mi). At current prices, a battery system of this capacity would cost between $2.5 and $5 million.  A CNG refueling system, based on the electricity-free, GoFlo compressor would cost a fraction of this amount without having to depend on the electric grid for power.

One unique characteristic of many emergency vehicle fleets is that they might need to be redeployed to a location other than their home base in the event of an emergency. Examples of such emergencies might be flooding, large wild fires, hurricanes, earthquakes, etc. Such redeployments are commonly required as a provision of “mutual aid agreements”. Redeployment of vehicles is not feasible if their fuel supply is not also re-deployable or otherwise locally available. The GoFlo compressor can uniquely facilitate such re-deployments, since the required natural gas supply is so widely and reliably available. The availability of the GoFlo compressor changes the calculus in being able to utilize CNG emergency vehicles in this way.

The GoFlo compressor is a game changer for managers of fleets that must be ready to serve the public, even in the event of emergencies and disasters. Clean and economical natural gas vehicles are now even more attractive for these operations.

Getting the Most from Your CNG Station Grant

by

How can the GoFlo help reduce costs?

Many state, regional, and local agencies are offering particularly attractive CNG station grants to help overcome the higher initial cost of CNG vehicles, and associated refueling equipment, as compared to similar gasoline and diesel equipment.

Fleet operators are realizing that now is a great time to become a leader in the cleaner fuel movement and make the switch to using natural gas to fuel their vehicles and many factors are driving this movement:

  • Diesel and gasoline fuels appear to be entering another phase of increasing cost.
  • The environmental benefits of CNG as a fuel, in terms of both greenhouse gas and criteria emissions such as particulates and NOX, are more clear than ever.
  • Renewable natural gas is becoming increasingly available for those operators whose goals are carbon-negative fleets.
  • The performance, durability, safety, and resale value of CNG vehicles is no longer a concern, as documented by the experiences of thousands of fleet managers all over the US operating every sort of CNG vehicle.

With all these factors in favor of making the switch to CNG vehicles, what more does a fleet manager need to know before making the conversion decision?

When considering installing a refueling system for your CNG fleet, the initial cost, even if covered by a grant, is only a portion of the cost of your refueling system. Consider the cost for the energy to power the compressor. You will likely find that a compressor powered by natural gas, instead of electricity, will save you a lot of money not covered by any grant.

The GoFlo® natural gas powered compressor gives fleet managers who prefer to have their own “behind the fence” refueling system a new option to reduce operating costs even further.

How can the GoFlo® help reduce costs?

To be used as a vehicle fuel, natural gas must be compressed to 3600 psi (the US standard) for storage in the vehicle fuel tank. This compressed natural gas is referred to as CNG. Such high-pressure storage provides a good combination in tank size, weight, and cost providing utility comparable to liquid fueled vehicles. Traditionally compressors capable of providing such high-pressure fuel have used an electric motor to drive a multi-stage compressor.

Electrically driven compressors come with a number of inherent disadvantages:

  1. Installation cost can be high since the electrical utility service must frequently be upgraded to provide the required 3 phase, 430/480 volt power (sometimes greater than 100 amps).
  2. Operation during electrical power outages (critical for fleets such as utility, trash haulers, transit and school buses, first-responders, highway maintenance, ports, etc.) requires costly standby electrical generators.
  3. Operating cost for the required electrical power is surprisingly high, and ever increasing.

Usually, these disadvantages are not considered in the selection of a CNG compressor, since virtually all commercially available CNG compressors are comparable in these metrics because they are all powered by electricity and are all similar in their efficiency of converting electricity to mechanical power to drive the compressor.

But, in the case of a CNG refueling system that is funded in whole or part by a grant, one of these disadvantages becomes especially significant: the operating cost for the electrical power. While a grant might partially or fully cover the higher installation costs and backup generator associated with an electrically driven CNG system, virtually no grant will cover the higher operating cost of such electrically driven systems.

How important might this be? The cost of this electricity must be compared to the corresponding cost of natural gas consumed by the GoFlo compressor in producing the same volume of CNG. We will use costs corresponding to a typical site in Southern California to illustrate this cost tradeoff. (If you contact Onboard Dynamics, one of our staff members can walk you through a sample comparison for your own fleet yard.)

In conclusion, remember to consider the cost of energy consumption to power a station CNG compressor. You will likely find that a compressor powered by natural gas, such as the GoFlo, will provide you cost savings not covered by a grant.
