Long-duration energy storage that can buffer the fluctuating output of solar and wind power plants will be key components in future power grids. Batteries are good for short-term storage, but for longer durations, we need other solutions. The most promising technologies convert electricity and store it as heat or compressed air. In all those systems, heat exchangers are key components. That is the reason Alfa Laval developed the Packinox+, which I will present in this video. But first I would like to say a few words about the round-trip efficiency. This is the ratio between the output and input of an energy storage system. And if you want to maximize it, you need heat exchangers with outstanding performance and high capacity. And on top of that, low CAPEX to make the solution commercially viable. For all these reasons, Packinox+ is the ideal solution. It combines, in the same heat exchanger, a true counter-current configuration and high-performance corrugated channels, which means you only need half the heat transfer area required in a shell-and-tube solution. This makes a huge difference on CAPEX when you need tens or hundreds of thousands of square metres and even more so if the requested material is stainless steel. Thanks to its unique design, a Packinox+ can operate with temperature programmes spanning up to 500 degrees Celsius and have more than 20,000 m² plate area in a single heat exchanger which reduces the number of units and the related installation costs. Other advantages are the low pressure drop, which helps increase the round-trip efficiency and the very high mechanical robustness and resistance to fatigue, which is essential in cyclical operations typical of energy storage. A Packinox+ is designed and finetuned for each customer’s requirements and operations. And thanks to Alfa Laval FlexFlow technology, it is optimized for highly asymmetrical flows, which are very common in this application. If you want to know more about the Packinox+ heat exchanger and all the benefits it can bring to your application, please contact your local Alfa Laval representative. Thank you for watching.
