1. Status Update – Coldry Small-scale Commercial Demonstration
In recent announcements (24 December 2020, 15 January 2021) the Company provided updates on the progress of its Coldry upgrade project, aimed at enabling the small-scale commercial demonstration of its unique, low-cost, zero-emission brown coal drying technology in Victoria, Australia.
Chairman, Glenn Fozard commented, “We’re pleased to report that overall progress on Phase 1 continues, despite several shipping delays and some severe weather events shifting the timelines of certain activities. At present, we anticipate completion of construction during May, ahead of commissioning and testing throughout May and June.”
Chief Engineer, Mr Ashley Moore added, “We’ve safely and successfully installed the main components of our primary processing train, namely the mixer, mill and extruder, following the completion of the required structural supports and clearing out the building’s prior equipment.
“In addition, we’ve disassembled the internal walls of our existing packed bed dryer (PBD), ready to install the newly fabricated walls, starting the last week of March. The new walls feature design and positioning changes driven by the accumulated operational experience with the prior Coldry pilot plant. These changes are aimed at further improving drying efficiency, increasing throughput and decreasing the cost of production.”
ECT Chairman Glenn Fozard added, “Although frustrated by the shipping delays, we have managed to limit the impact on the schedule.
“Successful completion of this small-scale commercial demonstration plant is part of our broader commercialisation strategy, which involves the further potential scale-up of our
Coldry process in Victoria’s Latrobe Valley, supporting the higher value, lower emission utilisation of lignite via a range of downstream applications, including solid fuel, liquid fuel, specialty chemicals and hydrogen production.”

2. ECT poised to demonstrate ‘gateway’ solution to future use of brown coal
The announcement by EnergyAustralia on 10 March 2021 that it would close the Yallourn power station in mid-2028 highlights the importance of Coldry as the ‘gateway’ solution for the future of Victoria’s brown coal resource.
Importantly, the closure does not affect the immediate Coldry project at Bacchus Marsh nor the ability to source lignite from the Yallourn mine for that project.
The closure does however raise the importance of Coldry as the ‘gateway’ solution for the future use of the resource and presents the current Coldry project, scheduled for commissioning in coming months, as the only meaningful scale demonstration of an alternative to power generation, for the low-emission application for the Latrobe Valley’s abundant, world-class coal resource.
ECT holds the view that unless a viable alternative use for lignite, other than high-emission power generation, is validated in the near term, the brown coal resource is at risk of being stranded, with billions of dollars of future economic activity possibly lost to the region. In this context, the Company believes that the success of the Coldry project at Bacchus Marsh can shine a light on that viable pathway for the future low emission use of the brown coal resource.
The Company looks forward to providing further information on this opportunity in future updates.
3. Hydrogen production (COHGen) – next stage commercialisation
Recently, the Company has received a great deal of interest from the investment market and shareholders about the progress of its highly prospective COHgen technology and is currently developing a strategy and associated budget for progression to the next stage of commercialisation.
COHGen leverages the Company’s Coldry and HydroMOR processes to deliver a unique method for producing hydrogen from brown coal.
Key benefits of the COHgen process include:
- Lower CO2 emissions than conventional brown coal gasification
- Lower carbon capture and storage cost, due to lower CO2 emissions
- Higher hydrogen yield per tonne of coal than conventional brown coal gasification
- Lower estimated cost than conventional brown coal, renewable and natural gas-based hydrogen production routes
- Utilises an abundant, affordable, environmentally friendly catalyst that can be used multiple times.
ECT’s Research Manager, Dr Vivek Ravishankar commented, “One of the significant ways to economically achieve net zero carbon emissions for brown coal-based hydrogen production is through the development of innovative technologies like COHgen that create novel ways to produce hydrogen that also channels the residual carbon into valuable by-products.
“COHgen’s ability to achieve lower CO2 emissions than conventional brown coal-based hydrogen production methods is due to most of the carbon in the coal being captured and stored in solid form within the process. We believe technologies, such as COHgen, can help unlock the future low emission use of brown coal, supporting energy security whilst maintaining reliability and affordability.”
Further details on the COHgen development strategy will be announced in due course.
4. Capital Management Update
The Company provided an update on 18 June 2020 following the initial COVID-19 lockdown period, noting the budget for the full implementation of the upgrade project had increased by ~$1.2 million and the timeline for the commissioning of Phase 1 had been pushed back to April 2021.
Currently, the project is on track to conclude construction of Phase 1 early May, followed by commissioning during the balance of May and June.
The Company further noted in its 18 June 2020 update that it anticipated that the increased cost would be financed by a number of non-dilutive solutions, including project and equipment finance, government grants, R&D tax initiatives and reduced or deferred capital expenditure.
At present, these solutions are expected to deliver the funding required to complete Phase 1.
Entering Phase 2, which involves the addition of the char kiln and associated integration components budgeted at ~$1.9M, the need to source further funding solutions is anticipated. The Company is exploring a range of options with preference given to non-dilutive options including:
- Increased R&D loan limits
- Government grant and funding programs
- Project contributions from strategic and technology partners
- Alternative debt funding solutions
There is also equity based funding potential via the listed options and existing Equity Lending Facility (ELF), although the outcome of these will be heavily influenced by share price:
- ECTOE options – Strike of 0.3c – fully diluted cash = $7.32 million
- ELF 2021 – Strike of 0.1c – fully diluted cash = $2.05 million
The Company has finalised the conditions precedent to start the drawdown of its new R&D loan facility with a $1.2 million limit.
We are looking forward to working further with specialist lender, RnD Funding, for ongoing financing solutions over the coming months in support of completing the funding for Phase 2.
The Company received the final insurance payment of $593,000, in January 2021.
Government grants and funding
There are a range of government grants and programs designed to support innovation across several key industry sectors, including minerals, manufacturing and energy exports.
Where the Company’s technologies meet the criteria of these programs, applications will be submitted in support of attracting funding or support for their development or commercialisation.
Driving this effort is ECT’s recently appointed non-executive director, the Hon. Neil O’Keefe MHR, who brings extensive government relations experience as a former Federal Member of Parliament.
To date, ECT has been building the momentum of credibility within government funding programs with the Company previously announcing participation in the following programs:
- Future Energy Exports Cooperative Research Centre (FEnEx CRC):
- FEnEx CRC is helping focus and drive hydrogen research efforts across industry and academia
- Government policy supports a technology-neutral approach, providing clear price and emission targets for industry:
- H2 (hydrogen) under $2 per kilogram by 2030
- CO2 emissions per kilogram of ‘clean’ H2 must be at least 60% less than the ‘benchmark’ threshold emissions of 10.9kg CO2 per kg of hydrogen
- Two hydrogen production pathways will receive support:
- Electrochemical – splitting water using an electrolyser powered by electricity
- Thermochemical – splitting hydrocarbons derived from natural gas, coal or oil, combined with carbon capture and storage (CCS)
- ECT will support the advancement of CCS hydrogen through the development of its two highly prospective technologies:
- COHgen – a unique and novel process for the low-cost production of hydrogen from lignite as an alternative to the gasification-steam reforming process
- Coldry – the world’s only low temperature, low-pressure lignite drying process which also features a net-zero carbon footprint, providing a cost-effective drying solution for both the COHgen process and the standard gasification-steam reforming hydrogen production process
- Innovation Connections: HydroMOR grant
- The Company has attracted support for the ongoing research and development of its HydroMOR technology.
- ECT, in partnership with CSIRO, has been awarded a $50,000 grant from the Commonwealth Government Department of Industry, Science, Energy and Resources toward a $100,000 project aimed at profiling the performance of the Company’s HydroMOR technology across a range of feedstocks.
- HydroMOR, which stands for ‘hydrogen metal oxide reduction’, is the Company’s lignite-based, hydrogen-driven, low-emission primary iron making process which enables the utilisation of alternative low grade and waste resources, improving the economic and environmental outcomes of primary iron production.
- HydroMOR utilises the Coldry process as its front-end drying and material agglomeration stage.
- Contracts have been executed and the activities are being led by ECT’s Research Manager, Dr Vivek Ravisankar.

6. Background Information
About the Coldry Upgrade Project
Enabling a modern, low-emission char manufacturing process
The Coldry upgrade project is poised to modernise lignite-based char manufacturing, allowing both the (natural gas-equivalent emission) production of char and paving the way for net zero-emission production of solid fuel (Coldry pellets).
Comprised of the scale-up the Company’s Coldry process and the addition of new char plant and equipment, the Coldry upgrade project entered the construction phase in late October 2020 (see announcement 21 October 2020).
These project activities are focused on the delivery of two key objectives:
- Engineering Scale-Up – Advancing Coldry technical development via an engineering scale-up featuring an increase in throughput (up to ~3.5x current capacity) and reducing the plant’s physical footprint by approximately half (compared to the previous Coldry pilot facility).
- Aiming to:
- Reduce scale-up risk for a future large-scale commercial demonstration plant (350,000 tpa+)
- Refine commercial-scale plant design
- Generate sufficient design and operational data to support bankable feasibility study and planning for the commercial-scale plant
- Aiming to:
- Commercial Demonstration – Small-scale commercial demonstration of the Coldry process integrated with a downstream application (char manufacture).
- Aiming to:
- Deliver up to $2.5 million a year of operating project cashflow from target revenues of approximately $6 million
- Demonstrate Coldry as a gateway to higher-value downstream applications
- Demonstrate Coldry as a net zero-emission drying technology and enabler of low-emissions downstream applications (natural gas equivalent or less)
- Support continued development of HydroMOR (low emission steel making) and COHgen (low emission hydrogen production).
- Aiming to:
The project is divided into two phases:
Phase 1 – Coldry process scale-up:
- Design, construction, installation and individual commissioning of each key stage of the process, including primary processing train, conditioning system and drying system
- Integration of the plant and equipment across each key stage of the process to establish continuous, steady-state operations
Phase 2 – Char process integration:
- Design, procurement, installation and individual commissioning of the char kiln
- Integration of the char kiln with the Coldry process to establish continuous, steady-state operations and waste energy utilisation for drying
By phasing the project in this manner, the Company seeks to mitigate the unpredictable risks associated with the impact of COVID-19, and the well-understood risks related to the scale-up and commercialisation of new technologies. As such, expenditure is limited to the amount needed to reduce each phase’s risk before proceeding to the next phase with increased technical and financial confidence.
The Company has identified the high-value char market as the ideal candidate application for the small-scale commercial demonstration of its unique Coldry technology.
Char is a well-established product in the Australian market as a barbecue fuel and metals reductant.
Char is also used to make ‘activated carbon’ products for use in filtration applications.
What is char?
Simply, char is ‘partially burned’ biomass produced using a process called ‘pyrolysis’.
That biomass is typically wood or coal.
The key is to heat the raw material in the absence of oxygen, avoid combustion, remove most of the moisture and ‘volatile’ components, and leave the remaining carbon in place.
The result is an active carbon material, which is useful in several applications.
The volatile matter is turned in to ‘gas’ along with residual moisture, forming a “synthesis gas”, or syn-gas that can be used to provide heat.
Waste energy from the char kiln will be harnessed and utilised to provide the drying energy for the Coldry process.
Modernising the old char manufacturing process for lignite-based coal
Char made from lignite, also known as brown coal, is well established.
Unlike char made from black coal, lignite-based char requires drying first.
Drying is easy. Drying efficiently, cost-effectively and with net zero-emissions, however, has proved elusive until now.
The dominant lignite drying method has been steam tube drying, which involves high heat and high pressure. Unfortunately, coal is burned to generate the steam needed to dry the coal, resulting in increased CO2 emissions.
Coldry can achieve low temperature, low pressure, low cost drying through a unique combination of:
- Brown coal densification (BCD)
- Waste heat utilisation
BCD is a physical and chemical phenomenon exhibited by a range of high-moisture coals that results in the expulsion of moisture and densification of the remaining coal solids.
The Coldry technology process involves several process stages:
- Mechanical Shearing: The majority of the physically trapped moisture is released via destruction of the porous structure of the coal, which is achieved via mechanical shearing, resulting in a coal slurry of suitable consistency for extrusion.
- Extrusion: The slurry is extruded to produce pellets of optimal dimension for subsequent drying.
- Drying: Ideally, waste energy from a co-located power station (or another low-grade ‘waste’ energy source) is utilised to cost-effectively evaporate the mobilised water within the pellets, delivering a finished product with less than 15% moisture.
The Coldry process has impressive benefits in comparison to the traditional drying processes, including;
- No direct gaseous emissions (including CO2, NOx, and SOx);
- Significant energy uplift compared to the raw lignite (8MJ/kg > 22MJ/kg);
- Thermally stable finished product, with reduced spontaneous combustion profile;
- Where commercially desirable, there is also the option to harvest evaporated moisture.
By converting high moisture, low calorific value lignite from a low-value material with limited usage opportunities into a high energy, low moisture, transportable solid fuel, Coldry opens up new markets and a wide range of applications. It also reduces the CO2 emissions intensity associated with utilisation, enabling greater sustainability of outcomes.
