The Positive Papers
- Zap Rocks. Add Water. Get Clean Hydrogen: IEEE Spectrum Energy
Eden GeoPower, led by CEO Paris Smalls, is testing electrical reservoir stimulation that fires high-voltage pulses between boreholes to fracture iron-rich rock and release hydrogen when water is added. In lab tests the method produced up to four times more hydrogen than unfractured samples; a 2025 field test in a Colorado mine increased rock permeability tenfold. The approach avoids the earthquakes and groundwater risks of traditional hydraulic fracturing because the fractures are created by rapid plasma expansion rather than high-pressure fluids. ARPA-E has already funded the work with $900,000 as part of a broader $20 million program across 16 teams. This builds on yesterday’s coverage of the renewables build-out by showing a potential new production method that could complement surface electrolyzers. The honest caveat is that no commercial-scale production rate has yet been demonstrated and the process will eventually deplete readily available iron surfaces, requiring restimulation. For a regular person this matters because affordable clean hydrogen could decarbonize heavy transport and industry that batteries cannot reach. The open question is whether any single stimulation method, or a combination, can sustain economic output long enough to matter at national scale. Eden’s pulsed-power devices, named Zeus and Thor, convert low-voltage DC into high-voltage bursts using Marx generators and have been tested on thumb-size rock cylinders before scaling to field boreholes. A 2024 pilot in an Oman oil field using steady DC power increased oil production by 30 percent in soft carbonate but required the switch to pulsed power for hard igneous rock. Rafael Villamor-Lora, vice president of R&D at Eden, notes the plasma channel expands rapidly to induce shock waves that create finer fracture networks than hydraulic methods. Douglas Wicks, former ARPA-E program director, shifted from skeptic to advocate after realizing geologic hydrogen is a repeatable chemical reaction rather than a one-time accumulation. Alexis Templeton, geomicrobiologist at University of Colorado Boulder, joined Eden part-time from 2023 to 2025 to guide geochemistry after her work on microbes that consume natural hydrogen. Other teams funded in the same ARPA-E round explore catalysts, underground heaters, and carbon-dioxide injection to increase surface area for iron oxidation. Laboratory studies show ideal reaction temperatures sit between 200 and 300 °C, with acidity, microbial communities, and water chemistry all affecting yield duration. Rita Esuru Okoroafor at Texas A&M University models indicate that fracturing, catalysts, and periodic restimulation with hydrochloric acid will likely all be required because fast reactions also deplete iron surfaces quickly and leave precipitates that clog pathways. Paris Smalls founded Eden in 2017 while studying at MIT and signed an agreement with an unnamed geologic-hydrogen startup for a field pilot expected to begin late next year. The company’s Massachusetts test site on a horse farm began fracturing operations in June 2026 after delays from weather and equipment issues. Villamor-Lora states the core remaining question is whether hydrogen can be produced fast enough to be economical at scale.

University of Missouri researchers found evidence that challenges a long-standing assumption about star clusters used as cosmic distance markers. The finding directly affects how astronomers calibrate distances to galaxies and reconstruct the expansion history of the universe. No new numbers on measurement error reduction are reported yet, but the work is described as a breakthrough that could reshape models. The honest caveat is that the result is still early and must be confirmed by independent teams before it alters standard candles in practice. For a regular person the payoff is more accurate pictures of how the universe evolved and what its future holds. The open question the hosts can argue is whether this correction will be large enough to shift any near-term policy or technology decisions.

After six mass bleaching events between 2016 and 2025, a recent monsoon brought cooler water and relief to the 1,400-mile reef system. Before the 1990s such events were exceptionally rare. The monsoon lowered temperatures enough to give stressed corals a recovery window. The honest caveat is that this is a temporary reprieve, not a reversal of the warming trend that caused the bleaching. For a regular person the story shows that natural weather patterns can still buy time for marine ecosystems when human emissions are eventually brought under control. The open question is how many more such reprieves the reef can count on before permanent losses mount. Source: goodnewsnetwork.org
Think Positive
Viktor Frankl observed that between any stimulus and our response lies a space where we can choose our attitude and action. That choice is the one freedom no one can take away, even when external conditions feel overwhelming. In the context of today’s energy and climate stories, the stimulus might be headlines about slow progress or technical setbacks; the response we control is whether we keep taking the next small step anyway. Practicing this begins with pausing before reacting to discouraging news and deliberately naming one concrete action still available to you. Today’s mental rep is to write down one current frustration, then immediately list the single smallest action you can take on it within the next hour.
The Lever
Email your congressional representative today through their official website contact form and ask them to support continued or increased ARPA-E funding for stimulated geologic hydrogen research. The first step is locating the representative’s site via a quick search, writing a short note that references the $20 million program and Eden GeoPower’s $900,000 grant, and hitting send; the task is complete once the confirmation page appears. The action costs nothing and takes roughly ten minutes. If even one percent of listeners sent a similar note, the volume of constituent input could register in staff tallies that influence future appropriations. The main barrier is uncertainty about what to say; copy the key program numbers from today’s episode and keep the message under 150 words. These impact estimates are rough because policy response depends on many external factors. Source: spectrum.ieee.org
