New Sky Energy

New Sky Energy is an award-­winning clean chemistry company based in Boulder Colorado. Their technologies focus on removal of hydrogen sulfide and CO2 from sour biogas and natural gas streams. New Sky designs, develops, and manufactures SulfurCycle equipment and chemicals for municipal and industrial desulfurization of natural and biogas streams. New Sky’s SulfurCycle process is the most sustainable and cost effective way to control hydrogen sulfide inside anaerobic digesters or biogas streams. SulfurCycle uses a water based, non-toxic suspension of metal oxide particles to capture and convert H2S into elemental sulfur. The H2S capture agent is regenerated in situ simply by blowing air through spent media, which converts captured sulfide into elemental sulfur. Media can be reused up to 30 times; significantly reducing chemical purchasing and waste disposal costs relative to conventional single use scavengers. By recirculating treated gas to digesters operators can control H2S levels inside digesters by treating biogas outside digesters. This dramatically reduces the need to use iron salts or other chemical additives for H2S control.
