(Press-News.org) Harmful emissions from the industrial sector could be reduced by up to 85% across the world, according to new research.
The sector, which includes iron and steel, chemicals, cement, and food and drink, emits around a quarter of global greenhouse gas (GHG) emissions - planet-warming gases that result in climate change and extreme weather.
This new study, led by the University of Leeds as part of its contribution to the UK Energy Research Centre (UKERC), found that decarbonising the sector is technically possible with a mix of “high and low-maturity” technologies - those that are tried and tested, along with upcoming tech that is not yet ready to be used in industry.
Lead author of the study, Ahmed Gailani, Research Fellow in Industrial Decarbonisation in Leeds’ School of Chemical and Process Engineering, said: “Decarbonisation is a global priority for governments, companies, and society at large, because it plays such a vital role in limiting global warming.
“Our findings represent a major step forward in helping to design industrial decarbonisation strategies and that is a really encouraging prospect when it comes to the future health of the planet.”
Net zero target
The UK has pledged to reduce its GHG emissions to net zero by 2050, meaning it will take as much of the damaging gases out of the atmosphere as it puts in.
This new research, published today in the journal Joule, looked at ways this could be achieved for industry. It found that established “medium to high maturity” technologies that involve carbon capture and storage, or fuel switching to hydrogen or biomass, can save on average nearly 85% of emissions in most industrial sectors.
It also suggests that low-maturity electric technologies, such as electric steam crackers - which are key equipment to produce petrochemical products - can theoretically decarbonise between 40% and 100% of the sector’s direct emissions. Other new electrification technologies can also help reduce emissions from energy-intensive processes such as steel, cement, and ceramics, which in some cases hadn’t previously been thought possible.
Some of the results from the study have already been included in a consultation on enabling industrial electrification by the UK’s Department of Energy Security and Net Zero.
Industrial products such as steel, chemicals and cement are widely used across the global economy. The demand for, and production of, these materials has increased significantly over recent decades, leading to high energy consumption and GHG emissions. However, global industrial emissions will need to be almost eliminated to meet the Paris Agreement targets on climate change.
Peter Taylor, a co-author of the study and Professor of Sustainable Energy Systems in the Schools of Earth and Environment and Chemical and Process Engineering at Leeds, said: “Industrial decarbonisation is challenging compared to other sectors but can be achieved if evidence-based strategies are designed to enable the development of new technologies, encourage investment in related infrastructure, and reduce other barriers that make it difficult for companies to take action.”
He added: “For the UK, if we don't decarbonise industry, we won't meet our climate change targets and ultimately industry will move elsewhere because, in the long term, people will be looking for products made in a clean, green way and if our industry can’t produce these then it will become the industry of the past, not the industry of the future.”
Additional barriers
Dr Gailani said the study describes the sector’s decarbonisation as “technically possible” because although the researchers had reviewed the technologies applicable, they hadn’t factored in other barriers, such as those related to social, economic or infrastructure issues.
He added: “We wanted to be explicit about the fact that our focus was the technical side of industrial decarbonisation. There are of course many other barriers to overcome. For example, if carbon capture and storage technologies are needed but the means to transport CO2 are not yet in place, this lack of infrastructure will delay the emissions reduction process. There is still a great amount of work to be done.”
The uptake of many industrial decarbonisation technologies is currently impacted by high capital and operational costs, even if their technical challenges can be resolved. Electrification technologies typically have 2-3 times higher operational costs compared to fossil fuel-based technologies due to the higher cost of electricity in many markets.
The study was carried out in collaboration with researchers from the University of Bath and Imperial College London, and assessed the technical potential for emission and energy savings from the most important emission-reducing technologies.
The team reviewed the published research and other sources of data to find the abatement options applicable across all sectors and their technology readiness level (TRL). They reached the figure of 85% by calculating the emission abatement potential for the most promising technologies in each sector and taking the average. The sectors analysed were iron and steel; chemicals; cement and lime; food and drink; pulp and paper; glass; aluminium, refining and ceramics.
UKERC Director, Professor Rob Gross, said: “Industrial decarbonisation is an important research priority for UKERC as finding the most appropriate solutions requires a whole systems approach. Many of the most promising industrial abatement options rely on having access to supporting infrastructure whether that is hydrogen and CO2 pipelines, or upgraded electricity connections.”
Further research
Dr Gailani said the research was an important first step to help policy makers understand the potential of different emission reducing technologies that could be used in each industrial sector and therefore help them to make informed decisions about the best way forward. However, the team also noted that further research was needed to understand the practical potential to implement these technologies in different countries and regions. This would require careful understanding of local conditions including the socio-economic context, policy, markets and regulation, business models, infrastructure, and resource availability.

Study finds brain mechanism for physical exercise improving mood
2024-01-31
"Only exercise can remove all kinds of doubts," Goethe said. Physical exercise is the lubricant between the body and the mind. Alleviation of anxiety by motor activity forms an integral part of our daily life; whether going for a walk to refresh our mind or running excessively in the park to recuperate from a stressful event, we are all well aware of the beneficial impact. In fact, the plain view that exercise can prevent anxiety and depression has been supported by accumulating prospective cohort studies in recent years. Yet, apart from some general interactions between the periphery of our body and our ...

Researchers overview recent progress and challenges in silicon-based anode materials for lithium-ion batteries
2024-01-31
Research in recent years displays that several chemical modifications (binders, composite materials, and electrolytes) provide superior stability and enhance electrochemical performance in Si-based anodes in lithium-ion batteries (LIBs). Thus far, several different chemical interactions on structural alterations to Si-based anode materials have been tried to enhance Li+ kinetics, structural stability, and volume development control throughout the delithiation/lithiation process.
Despite significant advancements, Si and Si-based electrodes are still in their infancy and are still far from finding widespread practical use. Si-based anodes face some difficulties, including substantial ...
News on drug-induced skin swelling
2024-01-31
Angiotensin-converting enzyme inhibitors - ACE inhibitors for short - are effective antihypertensive drugs. They block the formation of the hormone angiotensin II, which plays a central role in the development of high blood pressure. On the other hand, these drugs increase the concentration of the vasoactive signaling substance bradykinin. Among other things, this can lead to acute swelling of the skin or mucous membranes. In general, such swellings are not life-threatening. However, if they affect the tongue, throat or larynx, angioedema can be life-threatening for the patient due to the potential risk of suffocation. Research to date suggests that susceptibility to such drug-induced angioedema ...

Firing nerve fibers in the brain are supplied with energy on demand
2024-01-31
Brain function depends on the swift movement of electrical signals along axons, the long extensions of nerve cells that connect billions of brain cells. The nerve fibers are insulated by a fatty layer called myelin, which is produced by specialized cells called oligodendrocytes. These cells wrap around and insulate nerve fibers ensuring the rapid and efficient transmission of signals that is essential for brain function.
Oligodendrocytes sense and respond to the electrical signals
Now, a team of neuroscientists led by Aiman Saab at the Institute of Pharmacology and Toxicology at the University ...
Engineering viruses to kill deadly pathogens
2024-01-31
Northwestern University researchers have successfully coaxed a deadly pathogen to destroy itself from the inside out.
In the new study, researchers modified DNA from a bacteriophage or “phage,” a type of virus that infects and replicates inside of bacteria. Then, the research team put the DNA inside Pseudomonas aeruginosa (P. aeruginosa), a deadly bacterium that is also highly resistant to antibiotics. Once inside the bacterium, the DNA bypassed the pathogen’s defense mechanisms ...
