New Swedish Break-Through Technology Has Potential to Enable Emission-Free Quick Lime Production

Quick Lime is an essential component in the manufacture of so many materials from steel to paper; but its production also releases CO2. In Sweden, its production accounts for 19 percent of the country’s CO2 emissions together with the cement industry.

Now a Swedish startup has announced that it can potentially remove all emissions from the lime industry; and industry figures are backing up the results.

SaltX Technology has revealed a technology called Electric Arc Calciner (EAC), which can electrify the production of quick lime and, at the same time, separate and capture CO2 from the limestone.

The technology works by changing what happens during a process called calcination. For this to take place, fossil-fueled heating has to take place, but SaltX has replaced this with renewable energy heating. It has also ensured that the CO2 emissions are isolated and captured.

Today's manufacturing process for lime and cement is outdated and unsustainable, and emissions must be heavily decreased. We have rethought and applied innovative technology and knowledge from the ground up to create a net-zero solution that is scalable and has the potential to get started producing "green limestone." - Lars Croon

Lars Croon, Head of Process at SaltX, said that today’s manufacturing process for lime and cement “is outdated and unsustainable”, adding: “We have rethought and applied innovative technology and knowledge from the ground up to create a net-zero solution that is scalable and has the potential to get started producing ‘green limestone’."

The innovation will also be used as a charging reactor for SaltX energy storage solutions to increase charging temperatures for increased power and scalability.
