ENTROPY INC. ANNOUNCES INITIAL RESULTS OF CETRI TECHNOLOGY DEVELOPMENT PROGRAM AND EXECUTIVE TEAM APPOINTMENT
Entropy Inc., a subsidiary of Advantage Energy Ltd., has released initial results from its technology development program at the University of Regina's Clean Energy Technologies Research Institute (CETRI). It has appointed Jason Chadwick to Entropy's executive team.
Technology development update
Extended testing conducted at CETRI's world-class research facility has confirmed Entropy's proprietary carbon capture solvent (named Entropy23) possesses high-performance characteristics that significantly exceed industry standards. The recently completed phase 1 of CETRI's extended protocol was conducted using a gas mixture with 4 per cent carbon dioxide concentration in order to optimize the solvent blend for common postcombustion carbon capture applications, including natural-gas-fired turbines, reciprocating engines and boilers.
Prior CETRI research over the last five years that led to the discovery and formulation of Entropy23 was conducted using more traditional testing concentrations of 15 per cent. Together, the data sets demonstrate the broad applicability of Entropy23 across a wide range of postcombustion carbon capture applications.
The process of scrubbing carbon dioxide from a mixture of gases is inherently energy intensive. CETRI confirmed (using a simple screening method at 4 per cent CO2 concentration) that monoethanolamine (MEA, the industry standard carbon capture solvent) requires 12.15 gigajoules per tonne for the primary CO2 capture and regeneration process in the laboratory. Entropy23 requires 3.15 GJ/tonne for the same process, a step change reduction of 74 per cent. These physical properties directly impact the energy inputs required to capture carbon dioxide from a flue-gas stream and the costs of requisite equipment.
Highlights of the Entropy23 phase 1 extended testing include:
- Heat duty is about 3.85 times lower than MEA, indicating a major reduction in energy input costs and operating costs;
- Initial absorption rate is 66 per cent higher than MEA, indicating the potential to reduce equipment size and cost;
- Initial desorption rate is about 3.85 times that of MEA, indicating the potential to reduce equipment size and cost;
- Cyclic capacity is 85 per cent higher than MEA, indicating the ability to reduce the volume of solvent, equipment size and cost;
- Lean loading at 110 degrees is approximately zero, achieving nearly complete release of captured CO2 at lower relative temperatures, which is expected to further reduce energy requirements;
- Significantly lower NH3 emission rates than MEA, indicating high stability and lower solvent degradation, which is expected to reduce operating costs.
CETRI has now proceeded to phase 2 of the technology development protocol, which will include extended testing of Entropy23 using specific exhaust streams that match industrial emissions over multiple months, to confirm the enhanced degradation characteristics. The results of this phase are expected to be complete in early 2022, with regular progress updates throughout. The final phase of testing will be conducted beginning in Q2 2022 at Entropy's first commercial modular carbon capture and storage (MCCS) development at the Advantage Glacier gas plant, allowing Entropy to produce in situ, verifiable costs and energy intensity metrics for commercial applications by mid-2022.
When combined with Entropy's patent-pending MCCS process, Entropy expects Entropy23 to be an important technology in the global effort to decarbonize. Entropy intends to pursue a dual path business model, with some projects to be developed as owner/operator/carbon manager, and other projects to be developed as technology provider/licenser with associated carbon royalties.
Executive team appointment
Mr. Chadwick has been appointed vice-president of business development of Entropy, responsible for developing relationships with third party emitters, and developing the commercial agreements and structures required to navigate the full spectrum of the complex carbon capture business. Mr. Chadwick has 25 years of experience in Western Canada's upstream energy industry. Mr. Chadwick's prior experience includes serving as a senior vice-president, commercial, for Modern Resources, a private exploration and production company recognized for its industry-leading methane abatement and other low emissions technologies, where he was responsible for all corporate commercial and business development functions.
Continuing project development
Scoping design, engineering and subsurface evaluations are under way for each of the four projects under memoranda of understanding (MOUs announced June 2, 2021), with varying degrees of advancement. These MOUs, totalling approximately one million tonnes per annum (tpa) under development, are in addition to the previously announced project at the Advantage Glacier gas plant (182,000 tpa in two phases), where all major equipment required for phase 1 has been purchased and preparations for construction are under way.
Entropy continues to engage with numerous other third party emitters in a variety of industrial sectors and commercial applications, such as power generation, cement production and gas compression, with a significant pipeline of additional potential projects under development.
Entropy is committed to commercial deployment of state-of-the-art technologies in carbon capture and storage (CCS) and in other clean energy opportunities, building on the combined strengths of Advantage, Allardyce Bower Consulting Inc. (ABC) and its advisers from CETRI.
About Entropy Inc.
Entropy is a privately owned company (Advantage 90 per cent and ABC 10 per cent), founded to apply sophisticated science and engineering to commercialize CCS. Entropy's technology is expected to deliver commercial profitability at a carbon price below $50 per tonne, using proprietary MCCS technology. Entropy intends to deploy this technology in the global effort to reduce and eventually eliminate carbon emissions.
