ECT commences full feasibility for its headline project

Environmental Clean Technologies Limited (ASX:ECT) (“ECT” or “Company”) is pleased to provide the following update on the progress of the planning and development for its proposed commercial-scale project in Victoria’s Latrobe Valley, aimed at delivering a net-zero emission hydrogen refinery.

Highlights

  • Net Zero Emission Hydrogen Refinery feasibility underway
  • Refinery targeting material production of hydrogen-rich syngas and char
  • Significant government funding initiatives available to support low emission energy technologies

Net Zero Emission Hydrogen Refinery Hub Project

ECT is developing a ground-breaking new project for deployment in the Latrobe Valley, which will deliver clean hydrogen, agricultural char, and other valuable products with a net-zero emission footprint.

ECT’s Coldry technology will form the core of the raw material processing system, acting as the gateway enabler for an integrated operating plant. Coldry provides low-cost, zero-emission dewatering and drying of incoming lignite and biomass streams, which will then be fed into a thermochemical decarbonisation process (partial pyrolysis), creating two major product streams:

  1. A hydrogen-rich synthesis gas (syngas), also containing other valuable industrial gases for downstream use, and;
  2. A char product containing most of the incoming carbon (in solid form)

Diagram (above): the project involves two phases; Phase 1 entails hydrogen industry activation via an integrated utilisation pathway at scale enabling the manufacture of hydrogen and formic acid. Building upon this foundation, Phase 2 entails hydrogen industry expansion, developing and deploying our proprietary COHgen technology, which represents a significant advancement on conventional hydrogen production methods, featuring 70% lower CO2 emissions.

The hydrogen-rich syngas is then utilised by integrated downstream applications within the project to produce hydrogen, formic acid and generate electricity.

Formic acid is a valuable industrial chemical and serves a range of uses. In particular, it is a form of hydrogen-carrier generated through consumption of CO2 and H2, utilising some of the process CO2 emissions while producing a valuable product. In addition to being a hydrogen carrier, its primary application is as a preservative and antibacterial agent for livestock feed, with Asia being the largest, fastest-growing market.

Under the project’s first phase, syngas can be diverted from formic acid production to electricity generation during peak demand periods, providing a low carbon transitional step away from conventional lignite power generation. Subsequent expansion of the project in line with industry activation will further transition from syngas-fired electricity to 100% hydrogen-based electricity.

Upon completion of the initial stage of the project, this will see ECT become Australia’s largest producer of agricultural char for soil health and soil CO2 sequestration, and a substantial manufacturer of hydrogen, formic acid and emission-free electricity.

ECT Managing Director Glenn Fozard commented:

“We initially commenced scoping for a commercial scale Coldry project back in 2017. At that time, we also started highlighting hydrogen technology development. Energy and climate policy has finally caught up to what we’ve been saying for several years, and the market is starting to recognise the true potential for our technology suite. The initial feasibility review indicates a strong commercial potential, and as a result, ECT will commence full feasibility for this project to ensure our submissions for Government funding are powerful, compelling and competitive.”

Significant Government Support

Underpinned by the proposed commercial-scale hydrogen refinery, the Project aims to establish a new regional hydrogen hub, delivering substantial value to the region and significant jobs, training, and research opportunities.

Over recent months, significant funding initiatives have been established across federal and state governments in the form of grant or funding programs to help stimulate technology-driven climate transition and activate nation-wide hydrogen industry development. The proposed Project is aligned with several of these programs, for which ECT is currently preparing submissions, including:

  1. InvestVictoria – ~$50 million Victorian State Government program providing low-interest R&D funding facilities from $250,000 to $4M secured against future R&D Tax Incentive rebates
  2. Clean Hydrogen Industrial Hubs program – $462 million Australian Government program to help establish clean hydrogen industrial hub projects via implementation grants of up to $70M
  3. The Low Emissions Technology Commercialisation Fund – $1 billion Australian Government fund targeting support for technology development via 1:1 investment matching

Regardless of the funding sources, the Project will feature the production and utilisation of hydrogen from waste biomass and Victoria’s vast, world-class lignite resource. This Project is designed to support the transition of lignite use away from emissions-intensive electricity generation to a range of low and net-zero emission applications for domestic and export markets, featuring:

  • Net-zero emission footprint for the end-to-end process
  • Hydrogen for the in-situ production of formic acid
  • Synthesis (syngas) gas to produce hydrogen and to power a gas turbine
  • Formic acid production for supply to a range of markets
  • Agricultural char for soil health, carbon farming and CO2 soil sequestration
  • Speciality char products for a range of niche, high-value markets
  • Net-zero emission dispatchable electricity, to support peak demand periods via gas turbine and hydrogen fuel cells

Solving key barriers facing hydrogen industry activation in Victoria

The Project is designed to address challenges and obstacles to hydrogen industry activation in Victoria and the broader establishment of a hydrogen economy, including:

  1. High renewable hydrogen cost: Renewable hydrogen (made using electricity generated by wind and solar) is unlikely to meet price and volume requirements due to high cost, intermittency, and the demand from electricity consumers as further coal plants are retired
  2. Enabling infrastructure is required to activate competitive hydrogen production and utilisation within and export from Victoria
  3. Legacy asset constraints: The extent to which existing gas and other infrastructure can be adapted for future hydrogen use
  4. CCS Cost: The conventional approach to producing clean hydrogen from lignite, while cheaper than renewable hydrogen, is reliant on costly and complex carbon capture and storage (CCS); and
  5. Biomass supply constraints: Concerns exist around the total potential volume of clean hydrogen produced purely from biomass due to limited, seasonal supplies. Additionally, there is emerging evidence that questions the “green” status and sustainability of biomass combustion, which represents a potential future legislation risk to emissions standards for this feedstock.

A diversified approach is required to address the renewable hydrogen cost barrier, with ‘clean’ hydrogen extracted from the state’s vast, world-class lignite resource blended with biomass proposed under the Project. This approach will enable the timely development of scalable, affordable hydrogen production capacity, helping activate the industry in Victoria by justifying the deployment of the required infrastructure while solutions to bring down the high cost of renewable hydrogen technology are allowed to develop.

However, conventional hydrogen production methods from lignite emit CO2, requiring significant carbon capture and storage (CCS) to achieve the required low or zero-emission footprint.

The Company’s proposed Hydrogen Refinery provides a hydrogen production solution utilising Victoria’s vast lignite resource, blended with the available biomass, at a far lower cost than renewable hydrogen. In addition, unlike other methods for deriving clean hydrogen from lignite, the break-through net-zero approach being adopted by the Project does not require CCS and the associated costs.

Additionally, lignite will act as the reliable baseload of process feedstock, allowing for waste biomass utilisation without influencing primary biomass demand. Finally, due to maintaining the credentials of biomass recycling, biomass generated emissions from this Project will be future-proofed against possible legislation changes in this area, through soil CO2 sequestration offsets.

Eliminating Costly Carbon Capture and Storage (CCS)

Conventional CCS involves the separation of CO2 from the process gas stream, followed by compression, liquefaction, transportation and storage in geologically suitable underground locations. While this conventional approach to CCS is technically well-understood, it is energy-intensive and expensive.

The Project steps outside the conventional CCS approach, adopting a carbon capture and utilisation route that delivers a net-zero emission, revenue-generating alternative via a combination of:

  1. CO2 utilisation to produce valuable industrial chemicals
  2. In-process capture of solid carbon to manufacture valuable agricultural char
  3. Char impacts on soil, enhancing atmospheric absorption of CO2

The char product is ideal for a range of markets and applications, the principal being that of agricultural soil additive or AgChar. This sequesters much of the process carbon and creates improved chemistry and biology within agricultural land that enhances soil productivity and triggers additional absorption of atmospheric CO2. This latter impact potentially takes the Project to a net-negative CO2 footprint. In addition, char process parameters can be tuned to produce an ideal char feedstock for high-value markets, including specialty metals reductant, solid smokeless fuel and battery anodic material, through further downstream processes.

This combination circumvents the need for conventional CCS development and infrastructure, creating a circular outcome whereby ‘waste’ from syngas production (char) is used to create a secondary product of value for agricultural and other applications.

The Project entails an integrated set of applications that consume the bulk of the available waste energy outputs, recycling that energy back into the gateway Coldry process to create a highly efficient platform for net-zero hydrogen production from lignite and biomass.
