Experimental systems (Carbon/soot destruction) Halliwell

Halliwell, it's an interesting question you asked about carbon.As the world grapples with the escalating impacts of climate change, the need for effective carbon capture solutions has never been more pressing. Carbon capture and storage (CCS) technologies are emerging as a crucial part of the global strategy to mitigate greenhouse gas emissions, offering a way to trap carbon dioxide (CO2) produced from industrial processes and prevent it from entering the atmosphere. Various projects around the globe are pioneering methods to capture carbon, showcasing innovative approaches that could be scaled up to meet worldwide climate targets.

The significance of carbon capture projects lies in their potential to significantly reduce the amount of CO2 released into the atmosphere. According to the International Energy Agency (IEA), around 15% of the emissions reductions needed to achieve global climate goals by 2050 could come from CCS technologies. This statistic underscores the urgency of developing and implementing such projects, especially in industries that are hard to decarbonize, such as cement and steel production. By investing in carbon capture, we not only work toward cleaner air but also create opportunities for economic growth in green technology sectors.One of the most promising approaches to carbon capture involves direct air capture (DAC). This technology uses chemical processes to extract CO2 directly from the atmosphere.

Companies like Climeworks are leading the charge in this field with their ambitious projects, which aim to build large-scale DAC facilities that can remove millions of tons of CO2 annually. These facilities, strategically placed in areas with abundant renewable energy sources, can operate efficiently and contribute significantly to global carbon reduction efforts.
Another notable project is the Petra Nova project in Texas, which integrates carbon capture with existing fossil fuel power generation. By capturing around 90% of the CO2 produced from a coal-fired power plant, this project demonstrates how we can retrofit existing infrastructure to reduce emissions without completely overhauling our energy systems. This dual approach not only helps in mitigating climate change but also ensures energy security by continuing to utilize established energy sources while transitioning to more sustainable options.

Catalysts can significantly alter the pyrolysis process by promoting specific reactions or pathways. For example, certain catalysts can promote the formation of specific desired products or reduce soot formation.Reactor conditions play a crucial role in influencing the pyrolysis process and the resulting soot production.Catalysts can significantly alter the pyrolysis process by promoting specific reactions or pathways. The presence of other gases in the reactor can influence the pyrolysis process. For example, the presence of oxygen can lead to combustion rather than pyrolysis. 
These observations was that hydrocarbons are known to produce substantial particulate mass in combustion systems using man made technology

One of the primary challenges facing nature-based carbon capture projects is land use conflict. As the demand for land increases, especially in regions with high population growth or agricultural expansion, competition for land can intensify. This competition may arise between carbon capture initiatives and agricultural practices, urban development, or conservation efforts.While nature-based solutions are often framed as environmentally friendly, they can inadvertently pose risks to biodiversity if not carefully managed. For example, reforestation projects that prioritize fast-growing, non-native tree species can disrupt local ecosystems and harm indigenous flora and fauna.

The introduction of such species may lead to competition with native species, potentially resulting in a decline in local biodiversity.To mitigate these risks, it is vital to prioritize the restoration of native ecosystems and involve local communities in the selection of species for planting. By focusing on biodiversity-friendly practices, projects can enhance resilience against climate change impacts and ensure that carbon capture efforts do not come at the expense of ecological integrity.For instance, in areas where agricultural land is already scarce, introducing large-scale reforestation projects can lead to disputes over land rights and usage. Local communities that rely on the land for their livelihoods may resist such initiatives, viewing them as a threat to their food security and economic stability. To address these conflicts, it is essential to engage stakeholders in the planning process, ensuring that projects are designed to complement local needs and priorities rather than displace them.

CCUS has to be part of the solution. ITs not fully developed and commercialized as yet but IMO is an important part of the various pathways to de-carbonization. The existing renewable energy projects alone require so much land and storage to mitigate the intermittency to meet energy and demand growth rate. This is in addition to supply chain issues, lead time on projects etc etc.

Most CCUS projects never get off the ground because the technology is too expensive. Reducing oil and gas emissions with carbon capture can cost up to 10 times more than cutting the same emissions using wind and solar.
The Alberta Carbon Trunk Line (ACTL) in Canada had the largest carbon capture and storage capacity of all operational CCS facilities worldwide as of July 2023, at 14.6 million metric tons per year
CCS costs vary greatly depending on the concentration of CO2, type of technology, and industry.
The efficiency of carbon capture projects is not consistent across the board.
If leakage occurs, it could negate its environmental effect and pose a severe risk to human and animal health. CO2 stored in low-lying areas and at a high concentration paired with the capture of poisonous hydrogen sulphide would have a hazardous effect on workers and any other organism close to the vicinity.Researchers are developing innovative methods for monitoring and verifying CO2 storage in geological formations, ensuring long-term containment and preventing leakage.
Additionally, the long-term fate of stored CO2 remains uncertain.

The field of CCUS is constantly evolving, with researchers and engineers striving to overcome challenges and improve the efficiency and affordability of the technology.
These advancements demonstrate the ongoing progress in CCUS technology. As research and development continue, CCUS is poised to play a significant role in achieving a low-carbon future.
Combining CCUS with renewable energy sources like solar and wind power can create a more sustainable and cost-effective approach to emissions reduction.
Overall, CCUS presents a promising approach for tackling climate change by combining carbon capture, utilization, and storage. While challenges remain, ongoing advancements and a concerted effort from governments, industries, and research institutions can pave the way for a more sustainable future.


Direct Air Capture (DAC) has emerged as a promising technology for tackling climate change by removing carbon dioxide directly from the atmosphere. Several innovative approaches are being developed, each with its unique advantages and challenges.
While Direct Air Capture (DAC) holds immense promise for tackling climate change, scaling it up for commercial use presents significant challenges.Overcoming these challenges requires a concerted effort from researchers, engineers, policymakers, and investors. By addressing these hurdles, DAC can emerge as a viable and scalable solution for mitigating climate change and creating a more sustainable future.This technology uses specialized ​Monsanto membranes that selectively allow CO2 to pass through while blocking other gases. The captured CO2 can then be collected for storage or utilization.
Large-scale DAC facilities require significant land areas for deployment. This raises concerns about land-use competition and potential environmental impacts on ecosystems.

We get out what we put in. If mankind would make the effort to do the research and development it can happen. Too many socio-political agendas at play.

We built a system for South Korea 4 years ago; it's at the PDU stage, and we are having lots of engineering problems to solve.

It's not easy from a laboratory to outside, plus there are so many factors that come into play, in addition to costs of technology that are not proven yet.

Australia and New Zealand have such problems at the moment and are seeking answers to scale up from us.

Oh, it's easy to pump it back into the earth; think of the consequences of leaking into water supplies, agriculture, and humans, etc

Most of the oil and LNG deposits are located in basins or valleys. Check the hazards of fracking.

I am aware of the gas used for carbonating beverages, in particular beer, soft drinks, and wine. This prevents the growth of bacteria and fungi.
Carbon dioxide can also be used for decaffeinating coffee. We built a supercritical absorption plant for a coffee decaffeination using CO2.

The Scottish Government contacted us two years ago about its greenhouse plans for 2030; it is proposing such without the technology available.
The UK has plans for 5 of such proposals by 2050....

The only country that has a PDU is South Korea, and we built it. Co2 is very corrosive and even more dangerous with hydrogen sulphide.
One must use annealed steel to handle such, and its half-life is limited. We have tried Inconel , Monel , Hastelloy C , these materials show stress fractures
at certain pressures and cannot handle such an operation.

Please, you are reading glossy government publications , not knowing the limitations and problems associated with such CO2 operations.
Ask Scotland what seals they are going to use.
