The universe’s most common element, which exists in yet-unexplored underground deposits, could underpin a post-oil energy future in Alaska and beyond, experts say.
U.S. Geological Survey geologist Geoffrey Ellis stands on Oct. 29 by a poster diplayed at the University of Alaska Fairbanks that explains how pure hydrogen can be pooled in underground formations. Ellis is the leading USGS expert on geologic hydrogen. He was a featured presenter at a three-day workshop on geologic hydrogen that was held at UAF. , is in the ocean, in the sky, in the stars, in the bodies of living beings and – of particular importance to energy developers – in the ground.
In the future, Ellis said, there will likely be a need for 400 million tons of hydrogen, compared to thecurrently used. And the hydrogen currently used is not the type that is pulled from the ground. Rather, it is produced through an energy-consuming process that pulls the element out of other compounds, separating it from methane in natural gas or using electricity to separate it from oxygen in water.
For Alaska, where traditional fossil fuels can be expensive as well as environmentally burdensome, hydrogen energy could underpin development of other non-fossil-fuel energy. Geologic hydrogen could be an important part of the solution, said Mark Myers, a geologist and There are myriad challenges to geologic hydrogen beyond finding the resource, said experts at the UAF workshop. One is that hydrogen molecules are small, meaning they are not easily trapped in the pores of underground rocks. Another is that hydrogen molecules tend to attach quickly to those of other elements, potentially making separation ephemeral.in 2011, at a site where in 1987 an errant cigarette touched off an explosion at what was intended to be a water well.
Senate Majority Leader Cathy Giessel, R-Anchorage, has immersed herself in the subject of hydrogen. For example, she has been participating in meetings held by the, founded in 2022 by UAF’s Alaska Center for Energy and Power and the Department of Energy’s Arctic Energy Office.
