Industrial process heat and its huge climate impact have not received much public attention, since no commercially viable and scalable emission-free solution was available until now. HELIOVIS has developed and markets the HELIOtube®, the largest solar collector in the world, that provides zero-emission industrial process heat in the temperature range from 90°C – 400°C for up to 24/7 at prices competitive with fossil fuels and stable for years to come. This next generation solar technology enables the decarbonization of large-scale industrial processes in various industries throughout the world.
