About 20% of the industry’s vented emissions are located at sites that have high-bleed pneumatic devices and unreliable grid electrical power. In the last few years, Qnergy has deployed hundreds of its low maintenance remote power systems in Oil & Gas sites. Since the summer of 2019, Qnergy has successfully deployed its Compressed Air Pneumatic systems (CAP3) in the U.S. and Canada.

The rapidly increasing demand for the CAP3 air-pneumatic systems created a need for a creative financial solution that will alleviate the pressure on capital budgets. The CAaaS solution removes the capital barrier to mass adoption allowing operators to streamline their path to emissions reduction and regulatory compliance, which in some markets also translates into sellable carbon credits.

The new program allows companies to pick the most palatable path based on several options: They can either buy Qnergy’s compressed air system (CAP3) through conventional capital expenditure or buy CAaaS without the capital expense and long-term commitment.

In addition, companies have various options to offset the price with credits. They can submit carbon credits themselves or through one of Qnergy’s carbon advisory partners.

“Operators are under conflicting pressures to concurrently reduce emissions and cut expenses. We are thrilled to participate at the Gastech Virtual Summit and announce a program that not only offers the best technology, but also removes all financial barriers to adoption.” said Ory Zik, Chief Executive Officer of Qnergy.

“The CAaaS contract is very simple. Qnergy installs a CAP3 system and acts like a utility. We only charge for usage of instrument air and electricity. We have tested this simple arrangement with a number of operators and the feedback is extremely positive.” He added.

Qnergy Extends Engine Warranty on Compressed Air Systems to Three Years: No Questions Asked

Qnergy outperforms conventional gas generators on reliability, cost of ownership and ESG metrics. The extended warranty is an additional step in streamlining the deployment of the world’s most reliable generator.

 

Ogden, Utah, July 20th 2020 Qnergy Inc. (www.qnergy.com), the leading manufacturer of clean and reliable remote power in the 500 Watt to 10,000 Watt range, announced a three-year warranty program. The program applies to the compressed air pneumatics products.

Qnergy’s Stirling generators are enclosed systems that require no lubrication, maintenance, or repair, delivering tens of thousands of hours of uninterrupted operation. One of the many advantages of Qnergy’s Stirling-based generator is its reliability and the very low maintenance requirements. According to a NASA press release[1], the design is “the most reliable heat engine ever invented”.  Compared to an internal combustion engine the Stirling engine is sealed from the combustion gases and requires no oil changes, filter changes or field overhauls.

Qnergy is the only company that has a Stirling-based, stand-alone power generator. Thanks to the technology’s unparalleled reliability, oil and gas companies already rely on the system to meet their remote power needs. The PowerGen has proven itself to be more cost effective than alternatives. Thanks to near-zero maintenance costs Qnergy has experienced significant growth in 2018 and 2019.

Qnergy’s newest program is Compressed Air Pneumatics (CAP3). The application couples Qnergy’s remote power generators with air compressors, offering a low emission alternative to gas pneumatic devices currently used in the upstream and midstream oil and gas markets. CAP3 delivers over 10scfm of dry air for a zero vent, multi-well pad without any low-bleed pneumatic device conversions.

“The reliability of Qnergy’s Stirling engine outperforms all competition in remote power. Especially the internal combustion engine” said Ory Zik, Chief Executive Officer of Qnergy. “The three-year engine warranty is another step in our path to provide peace of mind to our customers”, he added.

In the last two years Qnergy has installed hundreds of remote power systems throughout North America. The demand for Qnergy’s power generators remains high even during the current market slowdown. This is primarily due to its high reliability and low maintenance requirements, while operating in challenging conditions where other technologies have failed.

“The Qnergy PowerGen is the most reliable Engine/Genset that I’ve ever had the pleasure of using in the field”, said Randy Kuhn, N.E. Operations Manager at Energy Water Solutions, who has been running the system for more than two years non-stop.

Qnergy’s CAP3 solution featured in E&P Magazine

Qnergy’s Compressed Air Pneumatics (CAP3) methane emission mitigating skid was featured in the most recent issue of Hart Energy’s E&P Magazine.  Here is what they had to say about Qnergy’s solution to keeping a lid on greenhouse gas emissions

In April, the OGCI fund, along with others, pro­vided Qnergy with $10 million in Series B funding to accelerate the deployment of its compressed air pneu­matics product, CAP3. The application, which couples Qnergy’s remote power generators with air compres­sors, offers a low-emission alternative to gas pneumatic devices, which vent spent gas into the atmosphere and are often used in upstream oil and gas operations

“Gas pneumatics are responsible for about 20% to 40% of the gas industry’s supply chain in North America,” said Qnergy CEO Ory Zik. “And methane is a very potent greenhouse gas at 25 or even 85 times more than CO2, and the gas industry is very sensitive to those methane emissions. Pneumatic devices are among the easiest to solve. The same technology that is used for these pneumatic devices can be used when you use compressed air or clean air as the source of power. All you need conceptually is a power generator that com­presses the air and replaces natural gas or methane as a source of power with compressed air.”

Zik explained that Qnergy’s technology is based on the Stirling engine, which generates electricity by a cyclic compression of air and gas at differing tempera­tures. Qnergy’s CAP3 system combusts the normally vented methane.

“The oil and gas industry is focusing aggressively on reducing methane emissions throughout the sup­ply chain,” Zik said. “About 20% of those emissions are low-hanging fruit that can be updated through pneumatic devices. After focusing intensely on fugitive emissions through leak detection and correction, now the next stage is venting, and this is what this technology serves.”

Sam Gabbita, OGCI Climate Investments venture director, said Qnergy’s technology was appealing to the fund because it offered low-cost and reliable energy that can be applied at scale across much of the industry.

“There are about 250,000 pneumatic devices just in the U.S. alone,” Gabbita said. “And these are emitting about 14 million tons of CO2 when you convert the methane equivalent. So the opportunity to use Qnergy’s remote power engine to basically run compressed air rather than typical methane was a beautiful marriage. We liked the fact that there was established technology, and we loved the fact that we could use this established technology to decarbonize an important part of the oil and gas value chain.”

Benchmarking Methane Mitigation Programs by Emission Reduction Ratio

By: Dominic Pituch and Ory Zik

On May 12, 2020 Alberta announced it achieved a preliminary methane reduction deal with the federal government. The province has revised the Alberta Energy Regulator’s Directives 060 and 017 to align with the draft equivalency agreement to give the oil and gas industry a single and clear set of rules for methane reduction.

The recent momentum of methane regulation and incentives in Canada is expected to accelerate the decarbonization of the natural gas supply chain in the region. Prioritizing projects based on their Emission Reduction Ratio (ERR) would improve the efficient utilization of methane mitigation funding. A simple measure of mitigation efficacy is the environmental benefits per public dollar. Funded technologies should eliminate at least a certain amount of GHG per dollar investment. The measurement is straight-forward and dovetails existing methodologies that are already used in Canada, such as the carbon credit analysis used in Alberta and Emission Reduction calculation used in British Columbia. Qnergy has successfully used this ranking with its customers, to help them deploy their own capital effectively.

The following analysis shares the methodology and data from a practitioner’s viewpoint.

ERR is defined as:

Where $Y and $Z represent the grant received and additional public money (respectively). X is the estimated greenhouse gas emission reduction in tons of CO2 equivalent (tCO2e).

For example, a project that receives $1,000,000 in grant money or royalty reduction and abates 50,000 tCO2e over 10 years will have an ERR of $20/tCO2e:

Under current market conditions and uncertainty, Qnergy recommends using a three-year time horizon.

ERR can be used to evaluate the efficient deployment of public or private funds. For example, consider a Tesla car. It costs approximately $75,000 over three years and abates about 15 tCO2e over that time period (assuming that it is charged with renewable energy). Therefore, the Tesla ERR would be $5,000/tCO2e.

A few of Qnergy’s customers are using the same ratio with their own capital. The calculation is essentially the same. For instance, if a system cost $150,000 over three years in terms of the Total Cost of Ownership (TCO) and abates 500 tCO2e per year (1,500 tCO2e over 3 years), then the ERR is 150,000/1,500 = $100/tCO2e.

Pneumatic devices powered by pressurized natural gas are widely used in the oil and gas industry for process control and chemical injection. These devices vent spent gas directly into the air threatening the clean fuel advantages of natural gas. Qnergy’s innovative CAP3 (Compressed Air Pneumatics) solution provides reliable electric power and clean dry instrument air. Considering the GWP (Global Warming Potential) of Methane is 25x worse than CO2 (IPCC AR4 100y), a typical CAP3 system can eliminate over 1000 tCO2e emissions per year. The table below compares the emissions reduction efficiency of a few instrument gas to air (IGIA) projects.

Note that this ERR approach is a straightforward application of the Marginal Abatement Cost Curve (MACC). Evaluating methane mitigation projects this way can aid industry in achieving emissions reductions in a cost-effective manner.
