A US$22 million investment round backed by names like Bill Gates, Hyundai and Sumimoto, aims to move the E-TAC technology toward commercial scale
In a promotional video, H2Pro says its E-TAC water splitting process is "the first technology to deliver energy efficiency of 95 percent ... compared to 70 percent of water electrolysis." The E-TAC devices, it says, are "inexpensive ... scalable, safer, and operate at higher pressure ... By 2023, we will deliver hydrogen at under US$2 per kilogram, and later this decade, at under US$1." A press release further clarifies: "coupled with anticipated reductions in the cost of renewable energy, H2Pro's technology will enable $1/kg green hydrogen at scale – making it the world's lowest cost green hydrogen."
