Gamechanging Zero Emissions Technology Gets Green Light

Download media release

Low Emission Technology Australia (LETA) has committed to invest up to US$5 million to test technology that would see power and hydrogen generated with near-zero to negative carbon emissions while producing feedstocks for other critical industries.

The Allam-Fetvedt (Allam) Cycle Syngas Combustor Project will design, build and test a technology that has the potential to produce electricity at a lower cost than conventional fossil fuel generation — with inherent carbon capture and zero air emissions.

The Allam Cycle Syngas Combustor Project was awarded to Parametric Solutions Inc. through a cooperative agreement with the US Department of Energy (US DoE) with LETA as a cost-sharing partner.

LETA Chief Executive Officer Mark McCallum said the decision to invest in developing a revolutionary zero-emissions power and hydrogen plant was an important milestone on Australia’s — and potentially the world’s — path to a net-zero carbon emissions future.

“Renewables are playing an increasingly significant role in Australia’s energy mix, however their variability means that it’s critical that we develop partner technologies that can generate this electricity in a cleaner way,” he said.

“While we can look to hydro power or batteries, this technology gives us another partner for renewables.

“The Allam Cycle can deliver electricity from coal that, unlike conventional coal-fired power, coproduces clean hydrogen, captures its CO2, and can quickly ramp up and down at a similar rate to natural gas, enabling the grid to manage higher levels of intermittent renewable sources.

“Using our available, diverse sources of power, we end up with clean, affordable, reliable electricity, on-demand, whenever we need it and want it.”

Traditional power plants use hot steam — produced by burning fossil fuels mixed with air — to spin turbines and generate electricity. The Allam Cycle instead uses high-pressure fluid CO2 — created by burning a mixture of natural gas or syngas from coal or biomass with pure oxygen. No water is needed.

A natural gas-based Allam-Fetvedt Cycle — the NET Power project — was demonstrated at La Porte, Texas. The Allam Cycle Syngas Combustor Project will develop a commercially applicable syngas sCO2 combustor, allowing the technology to be applied beyond natural gas and run on syngas fuel from coal and biomass.

Mr McCallum said the Allam Cycle could help Australia meet its international climate commitments and transition to a low-carbon economy.

“While there are immediate domestic applications for this technology given that Australia is one of the world’s largest exporters of both coal and natural gas, there is significant value in investing in this zero-emission technology as Australia’s trading partners look to meet their own emission reduction obligations and energy needs,” said Mr McCallum.

“This is a strategically important project with the potential to unlock a revolutionary technology that can not only benefit today’s emissions-intensive sectors, but help create new, clean industries of the future.

“Clean hydrogen is one, and ammonia for fertiliser is another. This fits very well with Australia’s opportunity to develop new manufacturing industries and become a world-leader in clean energy exports.”

The combustor test is complemented by another LETA-8 Rivers Capital project exploring the feasibility of deploying the Allam Cycle technology to Australia for near-zero emission energy and hydrogen generation from Australian coal sources.

“Together, these two Allam Cycle projects aim to prove that this technology’s use at scale would introduce near-zero emission hydrocarbon and biomass power for Australia — complementing renewables’ increasing role in the energy mix — and that competitive, zero-emission industries like hydrogen and fertiliser can be created using CCUS, coal and even natural gas,” said Mr McCallum.

Mr Bill Brown, CEO of 8 Rivers Capital said “8 Rivers is grateful for the support from LETA and the US DoE to accelerate the deployment of zero-emission technologies aimed at ensuring the world can meet every climate target at a price of electricity that every human being can afford.

“This combustor project will allow Australia and the rest of the globe to generate both hydrogen and electricity from syngas with every zero-to-negative carbon emissions.”


Notes to editor

1. The Allam-Fetvedt Cycle is an advanced supercritical CO2 power cycle that burns fuel with pure oxygen and uses the CO2 by-product to drive a turbine, allowing for high efficiencies to be reached with inherent CO2 capture, near-zero air emissions, high flexibility, and zero required water use. 2. The Zero-Emission Supercritical Carbon Dioxide Syngas Oxy-Combustor Development and Testing project (the Allam-Fetvedt (Allam) Cycle Syngas Combustor Project) will design, build and test the world’s first syngas-fuelled supercritical carbon dioxide (sCO₂) combustor for the Allam-Fetvedt Cycle. Specifically, it will develop a syngas-fuelled 50 MWth combustor designed to be utilised with high-pressure, high-temperature, oxy-fuel, supercritical carbon dioxide (sCO₂) power cycles, with particular focus given to the conditions required by the AllamFetvedt Cycle, in order to lower the cost of coal power with near-100 per cent carbon capture below that of current state-of-the-art power systems 3. This allows for clean hydrogen production, as hydrogen is separated from syngas for export, before the syngas enters the combustor for power generation. 4. The Allam Cycle Prefeasibility Study will explore exploring the feasibility of deploying the Allam Cycle technology to Australia and establishing a business case for: • a new power station that must co-exist in a renewable energy dominant grid • an ammonia and urea production-focused facility that also generates electricity, and • a ‘blue’ hydrogen facility that generates electricity. 5. There are strong synergies between the Allam Cycle projects and LETA’s plans to establish a carbon hub in Queensland. 6. Carbon storage is a critical part of the equation when it comes to enabling a net-zero emissions future and establishing new, clean industries, including hydrogen. 7. Queensland has world-class carbon storage sites capable of permanently and safely storing potentially billions of tonnes of CO2 from many sources. Access to this and the infrastructure needed for world-class export industries in Gladstone makes Queensland an ideal site for a multi-industry carbon hub and regional hydrogen export hub.

About LETA
