BEND, OR June 15, 2021 – Onboard Dynamics has responded to the critical need to reduce methane releases into the atmosphere with their latest product launch of the GoVAC™ Flex. This simple, mobile, fully integrated solution will provide operators of natural gas pipelines a tool to safely minimize their greenhouse gas (GHG) emissions during routine pipeline maintenance.

As part of the product validation process with actual pipeline operators, successful pipeline evacuation projects have been held at utility companies in Oregon, California, and Nevada. The GoVAC Flex will be a key contributor to the mission of these companies in finding innovative clean natural gas solutions that are crucial to reducing GHG emissions while providing an affordable and sustainable energy future.

The GoVAC Flex is self-contained and fueled solely by a small amount of the natural gas that is being recovered during the evacuation process. It can draw a pipeline down to near zero psig and transfer the gas into an adjoining line at any pressure or compress the gas up to 3600 psi into a tube trailer for transport to another pipeline or end use location.

“We developed the GoVAC Flex to help our customers reach their critical goal of reducing greenhouse gas emissions,” said Rita Hansen, CEO of Onboard Dynamics. “We’re excited to launch this new product and demonstrate our leadership in the clean energy technology marketplace.”

The GoVAC Flex is small enough to be pulled by a half-ton pickup making it easy to transport to and maneuver around a job site. Despite its small size, it can evacuate a pipeline in less time than other approaches that require multiple pieces of equipment. Because it operates on clean natural gas, a pipeline evacuation operation utilizing the GoVAC Flex emits less GHG emissions than products that use a diesel-powered air compressor.

Founded in 2013, Onboard Dynamics is leading the climate-tech revolution with its unique, patented, mobile, and modular technology platform to responsibly manage and use natural gas. The innovative products based on this platform enable customers to achieve economic value and environmental benefits by simplifying the compression and transfer of natural gas. Whether deployed at a remote pipeline job site, in an oil or gas production field, at a dairy renewable methane recovery project, or at a fleet yard hosting clean natural gas vehicles, its products can compress natural gas or renewable natural gas from any source for convenient transfer via pipeline or high-pressure tanks for environmentally effective use. And there is never a need for an external electrical power source or diesel for operation.

During the past few years, we have seen growing interest in the concept that in order to achieve “net zero” carbon emissions, all end use energy should be delivered via electricity. This electrical energy can then be converted to many end use requirements without the release of greenhouse gases (GHG) at the end point. This logic has been applied to virtually every energy demand, from transportation to buildings. Possible carve outs might be some industrial applications that require large quantities of high temperature heat (steel and cement making) and long-distance air travel. These specialized demands might be met with a “green” fuel like hydrogen produced from renewable sources. The reasoning behind this approach has been that we “know” how to make carbon-free electricity via renewable energy technologies, like solar photovoltaics and wind turbines. (Some would also include nuclear power.) These electrical generation technologies are sufficiently developed that there is little associated technical risk in their expansion. And we have seen major cost reductions in the past couple of decades that should continue into the future. While leaving open some issues like industrial heat and long-distance air travel, electricity has seemed to many as a strong foundation to move aggressively against ever-growing GHG emissions.

A recent report by the International Energy Agency, The Role of Critical Minerals in Clean Energy Transitions, adds new realism to the challenges of achieving such an “all-electric” future. This detailed analysis points out that most of the technologies essential to an extensive conversion to electricity, such as photovoltaic systems, batteries, electric motors, and expanded transmission lines, will require much greater volumes of select minerals (such as lithium, nickel, manganese, cobalt, rare earths, aluminum, and copper) than required by our current, fossil-fuel intensive system. For example, an electric car requires about 5 times more of these minerals than a conventional automobile. A land-based wind turbine requires nearly 7 times more of these minerals than would a natural gas power plant of comparable output. A photovoltaic power system would require about 4 times more of these materials. Additional examples of mineral requirements for many of the key technologies are shown in the following chart from this report. (Note: In making these estimates for mineral requirements, the IEA took into account projected technology improvements that should reduce the need for some materials, such as cobalt required per kwh for batteries.)

Aggregating demand for these minerals across all the required electric technologies causes 2040 demand to increase by 42x for lithium, 21x for cobalt, 19x for nickel, and 7x for rare earths. Other minerals require similar growth, as shown in the chart below. The IEA report documents that around the world, it takes on average at least 16 years to develop a new mine. Having enough mineral supplies to achieve electrification goals will be extremely challenging.

Compounding the challenge of increasing mining and processing capacity of such materials is the fact that most of these minerals are currently sourced (mined and/or processed) from countries, such as China, Myanmar, the Democratic Republic of the Congo, Russia, and Mozambique, that many do not view as reliable trading partners around whom to build a durable, resilient next-generation energy system. Some of these countries also have less strict environmental standards than the US and other western nations, so expanding mineral extraction and processing in these locations can have negative environmental and health, and safety concerns. Experiences learned during the recent pandemic with critical medical equipment, such as PPE and ventilators, have made us all aware that a durable ecosystem/supply chain is essential to ensure social safety and security.

To further illustrate the size of this challenge, a recent article in the Wall Street Journal reports that major mining companies producing “technology metals”, such as copper, cobalt, and lithium are not currently investing enough in new production to even replace current production …. let alone increase it.  

The analysis provided by the IEA essentially shows that transitioning to an all-electric energy economy is essentially replacing a fossil fuel intensive energy system with a mineral intensive one. Drilling and refining are essentially replaced by mining and processing. Some unreliable trading partners are simply replaced with others with similar concerns. There is no “get out of jail” pass to side-step these challenges.

We do not need to turn our backs on efforts to increase electrification to reduce greenhouse emissions. But we’d be wise to retain, improve and de-carbonize traditional energy supply systems at the same time we seek new options. Reading the IEA report should be considered an essential part of understanding the risks and challenges we face in pursuit of our long-term energy and environmental goals.
