Carbon capture begins at NTPC’s power plant in India

Carbon capture is underway at NTPC’s 500MW coal-fired power plant (Unit-13) at Vindhyachal  Super Thermal Power Station, in Madhya Pradesh, India.

NTPC Energy Technology Research Alliance (NETRA) has selected Carbon Clean and Green Power International Pvt. Ltd to set up the carbon capture plant at NTPC Vindhyachal. This plant is designed to capture 20 tonnes of carbon dioxide (CO2) per day, which will use a modified tertiary amine to capture CO2, from the flue gas of the power plant. The CO2 will eventually be combined with hydrogen to produce 10 tonnes per day of methanol through a catalytic hydrogenation process.

The capture of CO2 from the flue gas of coal-fired power plants, and its conversion to methanol, is a priority area for NTPC and is expected to create potential new business opportunities and revenue streams for the company.

Aniruddha Sharma, Chair and CEO of Carbon Clean, said:

“We are thrilled to see our technology begin to capture carbon from NTPC’s plant and look forward to seeing how the CO2 to methanol project develops in the future. This project demonstrates how carbon capture supports industrial decarbonisation, as well as providing opportunities for companies to join the growing circular carbon economy.”

Surbhi Puri, Director, Green Power International added:

“It is a great honour and achievement to successfully demonstrate the carbon capture project at NTPC’s Vindhyachal plant. It is a matter of great pride for us to work with Carbon Clean on this project that will help deliver a greener and cleaner future. Decarbonisation through carbon capture is the future. With this small contribution towards the net zero economy, we hope to inspire the industry to make further strides in this decarbonisation drive.”

Carbon Clean’s CDRMax™ carbon capture technology can be used with point source gases that contain CO2 concentrations between 3% and 25% by volume and produces CO2 with purities greater than 99%, which can then be sold, re-used, or sequestered. The CDRMax™ process uses the company’s proprietary solvent, process equipment design, and advanced heat integration to significantly reduce both capital and operating costs.

ORNL, CHASM™ partner to drive decarbonization of cement

The U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL) and CHASM™ Advanced Materials (CHASM) are joining forces to advance scalable decarbonization technologies from discovery through deployment through a new memorandum of understanding, or MOU.

The production of cement, an essential ingredient of concrete, is responsible for 8% of the world’s anthropogenic CO2 – nearly 3 billion tons per year. The high-temperature process (-1450 °C), known as calcination, converts calcium carbonate (CaCO 3), the principal component of limestone, to calcium oxide (CaO), or lime, releasing CO2. CO2 is released from both the heating process (40%) and the reaction during calcination (60%). Overall, the process emits more than 800 kg of CO2 for every metric ton of cement produced and represents most of concrete’s overall carbon footprint.

One common way to reduce concrete’s carbon footprint is to substitute cement with other cementitious materials like fly ash, but the use of high volumes of fly ash can substantially reduce the overall stiffness, flexural strength and early compressive strength of concrete. Research has shown that the addition of very small quantities of carbon nanotubes (CNTs) led to the production of concrete with unprecedented improvements in mechanical properties, potentially offsetting the effects of high volumes of fly ash. However, these results were obtained using non-scalable processes to overcome the challenges of dispersing CNTs in the mixture.

CHASM Advanced Materials is a leader in creating innovative product platforms for a safer, more connected and sustainable world, and is actively pursuing partnerships to rapidly advance the development and manufacture of CNTs and CNT hybrids to decarbonize cement through its NTeC™ platform. CHASM is pursuing opportunities in applications that range from building materials to advanced manufacturing processes.

ORNL is actively involved in the development of materials with a broad range of applications from energy storage to advanced manufacturing. The purpose of the partnership with CHASM is to develop a collaboration roadmap to support CHASM’s develop and deployment efforts, and to explore opportunities where CHASM’s advanced technologies can help reduce carbon emissions associated with cement processes and materials.

“CHASM is proud to partner with Oak Ridge National Laboratory to accelerate scalable cement decarbonization solutions,” Dave Arthur, CHASM CEO, said. “We are on a mission to develop low-carbon, low-cost, cement, and our partnership with ORNL will redefine what’s possible for the national and global concrete industry.”

Under the new MOU, the potential collaborative activities may include:

  • Optimization of the proportion of CHASM’s additive, NTeC, to maximize fly-ash usage and displacement of carbon-intensive cement in concrete.
  • Optimization of the dispersion process of CHASM’s NTeC additive to be compatible with construction practices in the field.
  • Exploring the benefit of the demonstrated self-sensing property CHASM’s NTeC additive imparts in concrete for stress monitoring and life-cycle management of structures.
  • Developing a framework for deploying this solution across the construction industry.

UT-Battelle manages ORNL for the U.S. Department of Energy’s Office of Science, the single largest supporter of basic research in the physical sciences in the United States. The Office of Science is working to address some of the most pressing challenges of our time. For more information, please visit

Carbon Clean wins UK government innovation grant funding for carbon capture technology test campaign

Carbon Clean

Press release from Carbon Clean

  • Carbon Clean leads successful BEIS CCUS Innovation 2.0 bid
  • Non-aqueous solvent tested with both a rotating packed bed absorber and rotating packed bed stripper for the first time
  • Technologies promise to deliver high performance at a radically smaller scale than conventional solutions

A partnership project to test two innovative technologies which together are set to radically reduce the cost of carbon capture, has been awarded £600,000 in grant funding from the Department for Business, Energy and Industrial Strategy (BEIS) CCUS Innovation 2.0 programme, as part of the BEIS £1 billion Net Zero Innovation Portfolio (NZIP).

Carbon Clean, a global leader in industrial carbon capture technology, will partner with Doosan Babcock and Newcastle University to test the effectiveness of non-aqueous solvent (NAS) and a rotating packed bed (RPB) absorber and stripper together, for the first time. The project will assess the performance of NAS and RPBs by benchmarking against conventional packed bed absorbers and regenerators. In addition, an extensive parametric test campaign will identify optimal operating conditions for a range of simulated industrial flue gases.

The project will advance Carbon Clean’s expertise in carbon capture technology using RPBs, providing data to help further develop its innovative solutions.

In October last year, the company launched a groundbreaking industrial carbon capture solution, CycloneCC, which uses RPBs. The pre-fabricated, skid-mounted technology delivers high performance carbon capture in a unit that is up to ten times smaller than conventional carbon capture technology, with a five times smaller physical footprint. The ease of on-site integration for this carbon capture technology, combined with its cost efficiency, is expected to result in a huge uptick in demand from hard-to-abate industries seeking to decarbonise in line with net zero targets.

Prateek Bumb, Co-founder and CTO of Carbon Clean said:

“Scale and cost are the biggest barriers to widespread deployment of industrial carbon capture technology. Carbon Clean is focused on overcoming these challenges through the development of breakthrough modular solutions and this BEIS-funded project will ensure we continue to lead in this field, expanding our knowledge of rotating packed beds in carbon capture applications.

“We are proud to be among a growing number of partnerships between the public and private sectors, which are aiming to speed up the deployment of carbon capture technology. The IPCC has recently confirmed that global rates of CCS deployment are far below those in modelled pathways limiting global warming to 1.5°C or 2°C and has identified the need for technological innovation to address this issue.”

Energy and Climate Change Minister Greg Hands:

“As we accelerate the UK’s energy independence by boosting clean, home-grown, affordable energy, it’s crucial that our industries reduce their reliance on fossil fuels.

“This investment will help them to not only cut emissions, but also save money on energy bills, on top of supporting jobs by encouraging green innovation across the UK.”

An earlier BEIS-funded project, ARTEMIS, has already demonstrated the unparalleled CO2 absorption efficiency of RPBs in a 1 tonne per day (TPD) pilot plant. Demonstration scale testing has also shown the ability of NAS to outperform other industrial solvents (Monoethanolamine and Methyl Diethanolamine) in a conventional carbon capture system. The intensified mass transfer of RPBs, results in smaller equipment sizes at equivalent performance, while the improved solvent performance of NAS reduces OpEx, relative to the conventional use of MEA.

The testing will take place at Doosan Babcock’s Emissions Reduction Test Facility (ERTF) in Renfrew, Scotland and Doosan Babcock, along with Newcastle University’s School of Engineering, will be responsible for the operation and maintenance of the RPB units during testing.

Carbon Clean raises $150m in record carbon capture funding round

Carbon Clean

Press release from Carbon Clean

Carbon Clean has raised U.S. $150m from existing investor Chevron, who led the round, alongside CEMEX Ventures, Marubeni Corporation and WAVE Equity Partners and new investors, AXA IM Alts, Samsung Ventures, Saudi Aramco Energy Ventures and TC Energy. To date, Carbon Clean has raised $195m, having closed its $30m Series B investment round in August 2021.

The funding announced today will support Carbon Clean’s goal of becoming the world’s leading provider of carbon capture solutions for heavy industry, which accounts for around 30 per cent of global emissions. To achieve this, Carbon Clean will work in collaboration with industrial partners and governments to manufacture and ship hundreds of standardised, fully modular carbon capture units to industrial facilities every year.

Aniruddha Sharma, Chair and CEO of Carbon Clean, said:

“Carbon Clean’s vision is to deliver global industrial decarbonisation on a gigatonne scale, and we are now on track to do this by the mid-2030s. We are at the forefront of sector innovation, delivering products that can genuinely change the world. Today’s funding round is testament to the confidence of industry and global investors in our technology and its importance to reach net zero goals.

“Making carbon capture technology accessible for hard-to-abate sectors is a huge opportunity. We will use this new funding to scale production of our breakthrough fully modular technology which will overcome the biggest challenges facing widespread adoption of CCUS – cost and scale.”

In the past 12 months, Carbon Clean has achieved several significant milestones. The business reached the landmark of 1.5 million tonnes of carbon captured, launched CycloneCC – the world’s smallest industrial carbon capture technology, and signed partnerships with global industrial players like Veolia, CEMEX and Chevron, as well as with one of the most mature carbon capture and storage and hydrogen projects in the UK, the Acorn Project.

Now the focus is on delivering carbon capture on a gigatonne scale for heavy industry, achieving what solar did between 2010 and 2020: a +1,663% scale up in deployment.

Carbon Clean’s latest technology, CycloneCC, launched in October 2021, can be a game changer for hard-to-abate sectors like steel, cement, energy from waste, refineries and upstream/midstream oil and gas. CycloneCC has a footprint ten times smaller than conventional carbon capture, making it easily deployable in less than eight weeks. The solution has the potential to reduce CapEx and OpEx by up to 50 per cent and drive down the cost of carbon capture to $30/tonne on average, which would make the economic case for CCUS undeniable.

As part of the new investment made during this round, Carbon Clean and Chevron are seeking to develop a technology demonstration pilot that will test CycloneCC at one of Chevron’s co-generation plants in San Joaquin Valley, California.

Chris Powers, Vice President, CCUS for Chevron New Energies said:

“Chevron is proud to lead Carbon Clean’s record Series C funding round, and we look forward to partnering with Carbon Clean to help advance Chevron’s pursuit of lower carbon solutions. We have a long history of supporting the development and commercialisation of breakthrough technologies, and we’re especially excited about the potential for CycloneCC to revolutionise the industrial carbon capture sector.”
