20% of global carbon emissions are caused by industrial heat, and half of that comes from steam. At paper mills alone, steam production for drying paper products drives 80-90% of total natural gas consumption. Manufacturers are committed to reducing emissions, but 99% of industrial steam still comes from fuel-fired boilers. These boilers have historically been the only cost effective option to generate steam. Alternative technologies like electric boilers, hydrogen, and renewable natural gas (RNG) cost 3-5x more than natural gas, and most industrial heat pumps cannot produce steam at high enough temperatures and pressures for use in manufacturing. The manufacturing sector urgently needs a cost-effective, low-emission technology for industrial steam production. The Skyven Arcturus steam-generating heat pump (SGHP) produces emissions-free steam at the lowest cost and highest efficiency of any available technology. Arcturus electrifies steam production, leveraging high coefficients of performance (COPs) to generate emissions- free steam at a lower cost than natural gas boilers. It also enhances facility and grid reliability with a fully-redundant hybrid integration, seamlessly integrating with existing steam generation systems. Additionally, it uses 0 GWP water as its only refrigerant. “By leveraging waste heat and its high -efficiency, Skyven Arcturus delivers cost-effective, emissions-free steam that seamlessly integrates with paper mills and other manufacturing facilities,” said Jim Saccone, SVP Global Sales at Skyven Technologies. “The future of industrial steam is here, and it’s cleaner, more efficient, and more affordable than ever before." Unlike other heat pumps, Arcturus is capable of generating boiler-quality steam at temperatures and pressures up to 420F (215C) and 300 psig (20 Barg). To do so, Arcturus captures low-grade waste heat from commonly-available on-site heat sources, like paper machine exhaust, increases the temperature of that heat, and then uses it to generate boiler- quality steam.
