Hello connects, The tenth video in the 'Carbon Sequestration Lecture Series' is brought to you by Froilan Sequeira titled 'Energy Transition Metals' and can be accessed using the link below: https://lnkd.in/dYMuiVZA In this video, he will explain concepts such as climate change, different energy sources and what role do energy transition metals play in reducing the effects of climate change. He also talks about how mining can pose hazards to various communities and what steps must be taken to ensure that metals are mined without harming the surrounding ecology and communal harmony. The concepts in this video are explained in a way that the younger generation can understand as much as possible and lead the way for a better future. If you found this video insightful, do make sure to like and share the video.

Atmospheric concentrations of a class of ozone-depleting chemicals are beginning to decline thanks to the #MontrealProtocol, according to new research by a team including NOAA Global Monitoring Laboratory and CIRES scientists. https://lnkd.in/eUcaSWQ2

As recent #extremeweather events in the northern hemisphere have demonstrated, #globalheating is so far advanced that we will have to rely on some forms of #carboncapture to prevent the worst impacts of the #climateemergency. Research presented at the #Goldschmidt conference in #Lyon, #France, this month suggests that slag, the waste produced by the iron and steel industry, could be used to lock away #carbondioxide for thousands of years. Around the world about 400m tonnes of slag waste is generated every year. Some of it is used in construction, as road aggregate for example, but much of it remains heaped and unused. Jahmaine Yambing from the #UniversityofCambridge has explored the potential of slag heaps to capture carbon by studying the 20m tonnes of slag produced by the former Consett steelworks in #CountyDurham, #UK. Since the steelworks closed 40 years ago rainwater has drained through the slag, dissolving minerals and depositing tufa (a form of calcite) on the nearby stream bed. By analysing the deposits Yambing has assessed what chemical reactions have occurred and how much carbon has been locked into the tufa. Yambing is using this data to understand the carbon capture potential of other slag heaps around the world.

A safe climate depends on rapidly phasing out coal. #ClimateEmergency Yet global coal production reached an all time high in 2023, enabled by the US$470 billion in loans and underwriting provided to the coal industry by commercial banks like in just the last 3 years.

The fight against climate crisis brings Carbon Capture, Utilization, and Storage (#CCUS) into sharp focus. This process commences with the capture of carbon dioxide, employing pre-combustion, post-combustion, and oxy-fuel mechanisms. The lion's share of #CO2 originates from large industrial plants that harness both fossil #fuels and bio-fuels. Upon capture, the CO2 can be immediately repurposed on-site. Alternatively, following a process of compression and transportation, it can be utilized in a diverse array of applications, including #fertilisers, mineralization, and as a constituent in building materials. The CCUS process then advances to the stage of carbon storage. This phase involves the strategic #sequestration of CO2 into deep geological formations, such as decommissioned #oil and gas reservoirs or coalbeds. This method effectively isolates the #greenhousegas, preventing its release into the atmosphere. Globally, there is an abundance of sites equipped to facilitate these CO2 injections. The final stage in the CCUS process, #carbon utilization, presents a significant opportunity to bolster the viability of CCUS projects across a broad spectrum of sectors, including industrial, steel, cement, and chemical sectors. The captured CO2 is repurposed as a #feedstock, giving rise to a range of products, from concrete to methanol, ethanol, carbonates, and polymers. Drawing on projections from the International Energy Agency (IEA), we stand on the cusp of a transformative era. By 2030, we could be repurposing as much as 10 million tonnes of CO2 annually. This captured CO2 could fuel the creation of synthetic fuels, chemicals, and building materials, sparking the genesis of innovative usage areas in our continuous battle against climate crisis. Remember, CCUS is not merely a theoretical concept; it is an implementable solution that can make significant strides in the global combat against climate crisis.

👏 The Science Based Targets initiative has launched the world’s first science-based decarbonisation framework for all iron- and steelmakers 👏 Steel is a heavy emitting sector, accounting for up to 9% of global emissions. And 14% of the potential value of steel companies could be at risk from rising carbon prices by 2040 if the global industry does not reduce its environmental impact. This new SBTi guidance outlines how much, and how quickly, a company within the steel value chain needs to cut its emissions to limit global temperature rises to 1.5°C. https://lnkd.in/eGnRVQGa #SBTi #steelindustry #iron #carbonaccounting

Everything you need to know about Enhanced Rock Weathering (ERW) #carbonmarkets Over the past few months I have created a number of deep dives into the most important engineered carbon removal technologies: biochar, bio energy with carbon capture and storage (BECCS) and direct air capture (DAC). In the final post in this series I’m going to focus on enhanced rock weathering (ERW). In short, ERW involves accelerating the natural geological process whereby carbon dioxide is mineralised into rock. https://lnkd.in/eF3Y4a7z
