Leilac and Windship awarded £5m funding to demonstrate zero emissions shipping

Calix Limited is pleased to announce that a project led by Windship Technology Limited in partnership with Leilac, Calix’s 93% owned subsidiary focused on the decarbonisation of cement and lime, has been awarded £5m (~AU$8.7m[1]) by Innovate UK to demonstrate a novel, low-cost route to zero carbon shipping.

The Project combines renewably powered propulsion and a lime-based carbon capture solution for remaining emissions from conventional diesel engines. As part of the funding, Leilac will receive a grant of £1m (~AU$1.75m1) to demonstrate the delivery of lime to an exhaust gas scrubber for CO2 capture.

In welcoming the announcement, Calix Managing Director and CEO, Phil Hodgson said, “We are delighted to be partnering with Windship, with the support of the UK Government, to develop a novel decarbonisation approach that combines highly innovative technologies developed in Australia and the UK.”

Windship Technology CEO, Graham Harvey said,

“We are absolutely delighted with this funding for ourselves and our project partners. Given the significant financial support announced today, the Department for Transport and Innovate UK believe this technology can be a key driver in the clean shipping revolution, and we are proud to be playing our part in the decarbonisation of the shipping industry.”

Windship and Leilac’s partnership for zero emissions shipping

Windship and Leilac are partnering to develop an innovative wind propulsion and carbon capture system that has the potential to offer a low-cost route to low and zero emissions shipping. Together, Windship and Leilac’s technologies can enable approximately 50% of the ships power to be provided by renewable energy and emissions from the remaining conventional fuel requirements captured by zero emissions lime. Integration of the carbon capture system with the ship’s engines can enable waste heat recovery from the capture reaction, further reducing fuel demand. This unique combination of technologies has the potential to deliver a highly economical approach to elimination of emissions from shipping.

Windships’ auxiliary power systems use wind propulsion provided by wind rigs, each of which consist of three vertically arranged solid sails. The innovative design provides high-power density and a low centre of effort, and therefore minimal impact on vessel stability. Three triple wing installations can provide sufficient thrust to sail an 80,000 deadweight tonne (DWT) ship without requiring engine power for 60-70% of the journey along typical trade wind routes, dramatically reducing CO2 emissions compared with standard operating conditions.

For manoeuvring in port, handling in storm conditions or for when wind power cannot be guaranteed, ships must also be fitted with engines. Whilst in future these engines may run off zero emissions fuels, the existing fleet is expected to continue to use diesel for several decades.

Windship systems can be installed on vessels with a flat deck above their cargo, including tankers, bulkers, and LNG tankers.

Carbon capture for shipping

Lime is a highly effective sorbent for the capture of CO2 and can be used in a carbon capture system for the abatement of emissions from conventional diesel engines. For this solution to provide a net reduction or elimination of emissions, the lime used for capture must be produced with low or zero carbon emissions, using shore-based decarbonisation of the lime.

Leilac’s patented technology can produce low emissions lime by efficiently capturing the unavoidable process CO2 emissions released from limestone, without additional chemicals or processes. Leilac’s technology is compatible with clean energy sources, such as hydrogen and electricity, and also alternative fuels, enabling flexible and economical pathways for the production of zero emissions lime and cement. Leilac’s technology is proven at pilot scale, including through its pilot plant, Leilac-1, that has been in operation since 2019 with a capture capacity of 25,000 tonnes of CO2 per year. A demonstration plant, which aims to prove a low-cost module with a capture capacity of 100,000 tonnes of CO2 per year is due to open in 2024, paving the way for commercialisation of the technology at any scale.

For shipping, the decarbonised lime will be transferred to the relevant marine vessel, where the shipborne carbon capture process is applied. This system is compatible with a wide range of ship types, including tankers, container ships and cruise liners. It is retrofittable, fuel agnostic, and can be simply scaled to meet the decarbonisation ambitions of each ship. The adoption of lime as a sorbent for ships can also significantly expand the market for low and zero emissions lime.

Noting the benefits of research and development already undertaken by the cement and lime industries, Leilac CEO, Daniel Rennie said,

Graham Harvey

“This project marks a significant step in developing a potential route for the efficient and low-cost decarbonisation of the shipping industry. Marine shipping is a particularly hard-to-abate sector, and the very strong synergies that can be made from leveraging the large-scale industrial decarbonisation efforts in the lime and cement industries – combined with the innovative renewable approach by Windship – is an exciting development.”

Phil Hodgson

Dr Hodgson continued, “Calcium looping for carbon capture with low emissions lime is an exciting application with significant potential, and we look forward to developing this technology further with the support of our partners.”

The demonstration Project

The Project, led by Windship Technology Limited, will use a new patented solid wing sail technology in conjunction with a lime carbon capture system to demonstrate a route to zero emissions for ships fitted with conventional diesel engines. The Project aims to demonstrate the low-cost potential of the proposed decarbonisation solution for shipping and pave the way for zero emissions lime to be used for reducing or eliminating emissions from conventional diesel-powered vessels.

The key objective of the Project is to design, develop, build and demonstrate a novel drive train system consisting of a single powerful wind propulsion device, working together with a trial carbon capture system to pave the route to zero emission propulsion for bulkers and tankers. This will be installed and trialled on a 15,000DWT bulker. The shipborne carbon capture system will ultimately be designed to use highly reactive low emissions intensity lime, produced in an on-shore Leilac reactor, to capture CO2 from the ship’s exhaust gases.

Decarbonising shipping

International shipping is responsible for ~2% of global CO2 emissions.[2] The International Maritime Organization has an objective to reduce greenhouse gas emissions by at least 50% by 2050, compared with a 2008 baseline. Accounting for the projected growth of the shipping industry during this time, achieving this goal will require a reduction in emissions of ~80% based on current levels.[3]

Future development and adoption of sustainable transport fuels, such as hydrogen or methanol, together with the required supporting infrastructure, may enable low carbon fuel alternatives for the shipping industry.

When methanol produced with renewable energy and captured CO2 from industry is used as a fuel, such as in the process described in the recent HyGATE project announcement[4], of which Calix is a consortium member, the combination with the technology being developed by this Project can deliver net negative emissions from shipping.

About the Clean Maritime Demonstration Competition

The Project is part of the Clean Maritime Demonstration Competition Round 3 (CMDC3), which was announced in September 2022, funded by the Department for Transport (DfT) and delivered in partnership with Innovate UK. As part of the CMDC3, the Department allocated £60m to 19 flagship projects supported by 92 UK organisations to deliver real world demonstration R&D projects in clean maritime solutions. Projects will take place in multiple locations around the UK from as far north as the Shetland Isles and as far south as Cornwall.

The CMDC3 is part of the UK Shipping Office for Reducing Emission’s (UK SHORE) flagship multi-year CMDC programme. In March 2022, the Department announced the biggest government investment ever in our UK commercial maritime sector, allocating £206m to UK SHORE, a new division within the Department for Transport focused on decarbonising the maritime sector. UK SHORE is delivering a suite of interventions throughout 2022-2025 aimed at accelerating the design, manufacture and operation of UK-made clean maritime technologies and unlocking an industry-led transition to Net Zero.

Calix part of consortium awarded funding to manufacture sustainable fuels from captured CO₂

Calix is pleased to announce it is a member of an Australian-German consortium that aims to develop the production of sustainable fuels from renewable energy, green hydrogen and captured process CO2 emissions.

As announced by the Hon Chris Bowen MP, Minister for Climate Change and Energy on 27 January, the “HyGATE” Solar Methanol Project has been awarded AU$19.48 million from the Australian Renewable Energy Agency (ARENA) and €13.2 million (~AU$20.19m) from Germany’s Federal Ministry of Education and Research (BMBF) to develop a world-first green methanol demonstration plant in Port Augusta, South Australia.

Methanol and sustainable fuels

Exporting green hydrogen produced in Australia to Germany offers the promise of leveraging Australia’s abundant renewable energy resources to help the decarbonisation of German industry. Methanol is a versatile hydrogen derivative and has the potential to act as an effective green hydrogen carrier.

The clean and economical synthesis of methanol could help enable the decarbonisation of hard-to-abate transport sectors such as aviation and shipping, responsible for 4.3% of global CO2 emissions.

The Solar Methanol Project

The Solar Methanol Project aims to integrate several innovative low emission technologies to deliver renewable power and process heat, green hydrogen electrolysis, and, with Calix’s Low Emissions Intensity Lime and Cement (Leilac) technology, renewably powered electric calcination of limestone and the efficient capture of unavoidable process CO2 emissions.

In addition to Calix, the Solar Methanol Project consortium includes Australian cleantech company Vast Solar and leading engineering and consultancy firm Fichtner, and is supported by the Australian Solar Thermal Institute.

The Project intends to renewably power a 10MW electrolyser to produce green hydrogen, and a lime plant that produces CO2 as an unavoidable process emission. The clean energy, hydrogen and CO2 will then be used to synthesise up to 7,500 tonnes per year of green methanol to be developed for use as a sustainable transport fuel.

The Project aims to be a catalyst for a solar methanol industry in Australia, with the potential to significantly scale domestic green fuel use as well as potential exports to Germany and other global markets.

Low and zero emissions lime

To synthesise green methanol, the Project intends to use up to 15,000 tonnes per annum of CO2 captured by Calix’s Leilac technology during the production of low emissions lime.

Adbri is partnering with Calix and Leilac as part of its net zero pathway to enable the efficient capture of unavoidable process CO2 emissions and the use of renewable sources of energy in the production of low and zero emissions lime.

In collaboration with the Project and subject to commercial agreements, Leilac and Adbri are pursuing opportunities to develop a renewably powered lime plant that would produce low emissions lime and capture process CO2 for potential use in methanol synthesis by the Solar Methanol Project. While Calix and Adbri are not direct recipients of HyGATE funding, HyGATE represents excellent potential to derive direct value for captured CO2 into an opportunity with significant potential to scale.

Lime is an essential material for several industries, including mining and metals refining, water treatment, steel, paper, pharmaceuticals and agriculture. Decarbonising the production of lime is a critical enabling step for reducing the carbon intensity of these hard-to-abate industries.

Calix CEO and Managing Director, Phil Hodgson said:

“Calix’s Leilac technology will be used to make zero emissions lime iPhil Hodgsonn partnership with Adbri for Adbri customers, using renewable electricity and efficient capture of unavoidable CO2 emissions from limestone. At the same time, Calix and Adbri are excited to work with the Solar Methanol consortium to enable the supply of captured CO2 emissions to make green methanol.

We are delighted to be progressing plans with Adbri for zero emissions lime with electrification and CO2 capture. As part of the HyGATE consortium we look forward to the outcomes of the HyGATE project, which has the potential to further catalyse support for CO2 capture and to pioneer new green fuels for aviation and shipping.”

 

Mark Irwin

Adbri Interim CEO, Mark Irwin said:

“As a leading Australian producer of cement and lime with a commitment to be net zero by 2050, we recognise partnership with companies such as Calix are essential for the development of technology necessary to reach our goal. We are excited about the potential to supply zero emissions lime to our customers, a critical product in a decarbonised economy.”

Decarbonisation technology

Leilac's Technology

Leilac, a 93% owned Calix subsidiary with 7% owned by Carbon Direct, is a collaborative technology partner enabling sustainable decarbonisation of cement and lime.

Leilac’s unique technology is being developed to efficiently separate and capture unavoidable CO2 process emissions in cement and lime production, with no additional chemicals or processes.

Leilac’s modular, scalable and retrofittable technology is designed to be energy agnostic and electrification ready, providing viable, flexible and economical pathways to carbon free cement and lime.

Leilac CEO, Daniel Rennie said, “Scalable and low cost decarbonisation technology solutions for cement and lime are essential to ensuring a just transition to net zero that balances social, economic and environmental sustainability.

“Leilac’s technical approach, and the innovative commercial agreement that has been reached, paves the way for our continued and collaborative journey towards sustainable cement and lime.”

Heidelberg Materials and Leilac partnership

Heidelberg Materials is a founding and key member of a consortium of companies and institutions partnering to develop and apply the Leilac technology. The global licence agreement with Heidelberg Materials follows many years of close collaboration and partnership.

Leilac-1, located at Heidelberg Materials’ plant in Lixhe, Belgium, is a pilot plant supported by EU funding, with a capacity to capture 25,000 tonnes per annum of CO2. In operation since 2019, Leilac-1 has successfully piloted separation of unavoidable process COemissions from cement and lime production using the Leilac technology.

Leilac-2, also supported by EU funding and due to commence construction in 2023, will be located at Heidelberg Materials’ plant in Hanover, Germany. Once retrofitted to Heidelberg Materials’ operational plant, Leilac-2 should have the capacity to capture 100,000 tonnes per annum of CO2 or 20% of a typical cement plant’s emissions, and is aiming to have a low CO2 capture cost. The project paves the way for future deployments of the Leilac technology that scale to capture all of the unavoidable process CO2 emissions from cement and lime plants.

Cement, lime and climate change

Cement and lime provide the foundations of our societies and economies. They are also amongst the largest industrial contributors to climate change, accounting for 8% of global CO2 emissions[1].

Unlike other industries, most of the CO2 produced in the manufacture of cement and lime is unavoidable. It is estimated that 1.37 billion tonnes of CO2 from cement will need to be captured and stored annually by 2050.[2]

With no additional chemicals or processes, Leilac’s technology efficiently separates CO2 process emissions for use or storage. It aims to be energy agnostic and electrification ready, providing flexible and economical pathways to net zero cement. The Leilac technology’s unique, modular design is being designed to be retrofitted to cement plants with minimal operational impact, providing a transformational implementation approach that can be adopted at any scale.
