In contrast to conventional batteries like lithium-ion or lead-acid, which depend on certain components for electrical conduction, saltwater batteries utilize sodium, the identical ingredient present in ordinary table salt. This unique chemistry differentiates them from traditional battery technologies, offering an environmentally sustainable alternative that utilizes accessible, non-toxic materials. A saltwater battery (SWB) is a distinctive energy storage technology that utilizes natural seawater as its electrolyte, rendering it a sustainable and economical option. The battery consists of two primary compartments: the anode and the cathode, which are separated by a solid electrolyte. The predominant solid electrolyte utilized in sodium-ion batteries (SWBs) is sodium superionic conductor (NASICON) ceramic, which preferentially facilitates the movement of sodium ions between the two compartments.

New Paper: Towards Green and Low-Carbon Transformation via Optimized Polygeneration System: A Case Study of the Iron and Steel Industry by Mao Xu, Shufang Li, Yihan Wang, Qunyi Liu Polygeneration systems hold immense potential for driving energy conservation and emission reductions in energy-intensive industries like iron and steel. However, balancing multiple goals—such as cutting energy use, reducing air pollution, and ensuring economic viability—presents a unique challenge. This study dives into a case polygeneration system in the iron and steel sector, evaluating four polygeneration paths with 20 technologies, and also applies a multi-objective optimization model using NSGA-II to identify the optimal technology combinations that can: Achieve energy conservation up to 27.1%, Reduce air pollutant emissions by as much as 42.6%, and Deliver economic benefits to steel enterprises producing 3–9 Mt/a The results reveal not only the synergistic potential of these systems but also the conflicting relationships that need to be managed between energy, environmental, and economic goals. This research showcases how polygeneration technologies can transform waste and by-products like coke oven gas and steel slag into valuable products such as electricity, chemicals, and building materials—driving circularity in the industrial sector. As the iron and steel industry faces increasing pressure to meet pollution and CO2 reduction targets, embracing inter-industry polygeneration systems could be a game-changer for sustainable development.

Boost for Carbon Capture Tech The U.S. Department of Energy (DOE) is investing US$101 million to advance carbon capture, removal, and conversion technologies, a major leap toward reducing CO₂ emissions and accelerating sustainability in energy and industrial sectors. These technologies aim to capture CO₂ directly from industrial sources or the atmosphere and either store it underground or convert it into valuable products like building materials or fuels. Key initiatives include: • University of Illinois at Urbana: Developing a test center to evaluate cutting-edge carbon management for cement production, a sector responsible for approximately 7-8% of global CO₂ emissions. • Holcim US: Launching a Cement Carbon Management Innovation Centre at its Hagerstown, Maryland, plant to integrate carbon capture technologies and explore CO₂ utilization in cement production. Why is this critical? Cement production and fossil energy are among the largest contributors to global emissions, making carbon capture essential to meeting net-zero goals. Carbon capture works by intercepting CO₂ before it enters the atmosphere, using techniques such as post-combustion scrubbing or direct air capture. These advancements reduce emissions and turn CO₂ into economic opportunities. Brad Crabtree, DOE Assistant Secretary for Fossil Energy and Carbon Management, highlighted: “Carbon management technologies such as carbon capture can significantly reduce emissions from fossil energy use and key industrial processes, like cement production. By investing in test centers, we are helping reduce barriers to commercial-scale deployment of carbon capture, conversion, and removal technologies.” Source: Global Cement News, January 15, 2025 Will this carbon capture have an impact on the cement and construction industries?
