Swedish green steel
Swedish eco-friendly steel undertaking HYBRIT – that’s brief for Hydrogen Breakthrough Ironmaking Technological know-how – announced on Wednesday that it has designed the world’s initial shipping of metal produced without having utilizing coal. Volvo took the supply as a demo run right before the green steel goes into comprehensive professional creation in 2026. HYBRIT begun exam operations at its pilot plant in Luleå a year back.
HYBRIT was launched in 2016 by steel maker SSAB, point out-owned utility Vattenfall, and miner LKAB, all Swedish firms. Here’s how its steelmaking approach is effective, in accordance to HYBRIT:
The HYBRIT know-how requires changing the blast furnace process, which utilizes carbon and coke to take away the oxygen from iron ore, with a immediate reduction method where by we use fossil-free hydrogen produced from water employing electrical energy from fossil-absolutely free electrical power sources. As a substitute of carbon dioxide, drinking water vapor is fashioned.
Applying HYBRIT technological know-how, SSAB could most likely minimize Sweden’s total carbon dioxide emissions by about 10% and Finland’s by close to 7%.
Martin Lindqvist, president and CEO of SSAB, reported:
The initial fossil-cost-free steel in the entire world is not only a breakthrough for SSAB, it represents evidence that it’s feasible to make the changeover and noticeably cut down the international carbon footprint of the metal industry. We hope that this will encourage others to also want to speed up the green transition.
Solar panel recycling breakthrough
The condition-operate Korea Institute of Electricity Analysis (KIER) stated yesterday that a single of its exploration teams has formulated a method to recycle photo voltaic panels.
The KIER scientists say they can retrieve 100% of glass components and all around 80% of other products from solar panels in buy to recycle them into higher-performance photo voltaic cells. PV Magazine summarizes the team’s approach:
The novel procedure can be used to either damaged or undamaged panels and performs in 4 steps: The automated dismantling of the body and the junction box glass separation metal recovery and photo voltaic cell recycling…
The Korean group statements that the new procedure, which was, so considerably, examined on an undefined sequence of 72-cell panels, lowers ability use by a third when compared to other recycling technological know-how, thanks to process optimization. The system is also mentioned to allow the recovery of superior-high-quality glass with an iron content material of less than 200 components per million, and of a lot more than 65% of the components that make up a panel.
The researchers had been also able to refine the silicon recovered from waste panels to make six-inch one crystal ingots and wafers. The wafers had been made use of to manufacture a 20.05%, superior-effectiveness photo voltaic cell.
HST, a Korean photo voltaic-generating devices maker, is likely to use the KIER team’s system for commercialization.
