| Kelva Systems |
2025 ZH Formation |
None | |
| Kelva Systems is developing a novel technical approach to Thermal Energy Storage (TES) to support industrial decarbonization. TES stores energy as heat and releases it on demand. We provide flexible, on-demand steam generation for industrial processes, replacing fossil-fueled boilers and reducing CO₂ emissions in sectors like chemicals, food processing, paper, and district heating. We are developing a proprietary high-temperature concrete to act as the heat storage medium, at around 600°C. Unlike competitors that rely on off-site, containerized systems, we focus on bulk, on-site construction; significantly reducing insulation and transport costs. Our philosophy is to build systems that are locally sourced, as simple and robust as possible, and certified to last decades with minimal maintenance. We are initially targeting Switzerland and broader European markets, where policy and energy pricing increasingly favour TES. The Kelva Systems team brings decades of experience in clean energy, engineering, and finance. We are also partnering with Empa to advance development of our high-temperature concrete. | |||
