Right now, humanity is undertaking the greatest shift in energy sourcing since the 19th century. As we transition from fossil fuels to renewable energy there are some challenges we must overcome. One of the key issues is the changing output from wind and solar power plants. To avoid energy shortages and price spikes, we need some form of buffer storage to create a balance between supply and demand on the energy market. Batteries are very good for short-term storage, but for longer durations new solutions are required. Some of the most promising technologies currently being developed transform the electrical energy and store it as heat or compressed air. Heat exchangers are key components in these systems and Alfa Laval has recently developed a new heat exchanger for this application called Packinox+. Joining me today is my colleague Benoit Senechal who will tell us more. Benoit, can you please explain how Packinox+ heat exchangers help improve the overall efficiency of long duration energy storage systems? Ho, ho Emilie, I’m here! For sure I can. But first, I would like to say a few words about round-trip efficiency. This is the ratio between the output and input of an energy storage system and as the price of electricity increases so does the value of every extra percentage point of efficiency. Now, to maximize the round-trip efficiency, 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+ the ideal solution. It combines high-performance corrugated channels and a true counter-current configuration, which leads to a halving of the required heat transfer area compared to a shell-and-tube solution. This makes a huge difference on CAPEX when you require tens or hundreds of thousands of square metres and even more so when requested material is stainless steel. Since a Packinox can have more than 20,000 m² in one single heat exchanger the number of required units and the installation costs are reduced substantially. Thank you, Benoit. If you would like to learn more about Packinox+ heat exchangers and the benefits they bring in long duration energy storage, I invite you to contact your local Alfa Laval representative. Thank you for watching and let's keep in touch. Let's start a partnership to save energy every day.
