DOE awarding $20M to 16 projects on geologic hydrogen

The US Department of Energy (DOE) announced $20 million for 16 projects across 8 states to accelerate the natural subsurface generation of hydrogen. This is the first time that the US government has competitively selected teams to research this kind of technology.

The 16 teams announced are set to receive funding through two Advanced Research Projects Agency-Energy (ARPA-E) Exploratory Topics on geologic hydrogen.

The first Exploratory Topic—Exploratory Topic G: Production of Geologic Hydrogen Through Stimulated Mineralogical Processes—seeks technologies that stimulate hydrogen production from mineral deposits found in the subsurface, including developing our understanding of hydrogen-producing geochemical reactions and how to enhance or control the rate of hydrogen production. The following teams will work toward these efforts:

  • Colorado School of Mines. Geophysical Characterization and Site-Scale Real-Time Monitoring in Stimulated Hydrogen - $1,500,000. The Colorado School of Mines is developing real-time, efficient, and economical characterization and monitoring methods. Conventional monitoring techniques are too slow, sparse, and ill-tailored for measuring the mineralogical changes that produce hydrogen. Real-time feedback would enable the adjustment of stimulation parameters critical for maintaining hydrogen generation rate, which can change over the course of hours.

  • Eden GeoPower. Electric-Based Mechanical & Thermal Stimulation to Increase Geologic Hydrogen Reaction Rates in the Samail Ophiolite, Oman - $900,000. Eden GeoPower is developing a way to apply its electrical reservoir stimulation techniques to increase geologic hydrogen production through testing their stimulation methods on peridotite core samples from multiple sites to be selected in the Samail Ophiolite in Oman. The company's electrical stimulation method could produce significant surface area enhancement while also increasing the local temperature to promote reaction conditions suitable for hydrogen production. Experimentally testing how peridotite rock types respond to electrical stimulation could support identifying the optimal conditions and geologic formations for stimulation.

  • Koloma Labs. Enhanced Hydrogen Production: An Empirically Validated Modelling Approach - $900,000. Koloma Labs is developing geochemical and microbial models to understand the processes that form hydrogen in novel rock systems. A combination of geochemical, geo-mechanical, and fluid transport models paired with an investigation of naturally occurring microbiology in hydrogen reservoirs seeks to reveal the feasibility of the widespread stimulation of geologic hydrogen in different rock systems.

  • Lawrence Berkeley National Laboratory. Orange Hydrogen from Catalytic Low Temperature Serpentinization - $1,240,000. Lawrence Berkley National Laboratory is developing methods to understand the chemical mechanisms responsible for stimulating geologic hydrogen at low temperatures. Serpentinization rates are faster at higher temperatures, but the natural environment in future hypothetical geologic hydrogen production sites would have lower temperatures, meaning that reaction rates would not be as economical. The team is leveraging computation and experimental chemistry to determine how catalysts or other chemical approaches affect the formation of geologic hydrogen in low temperature environments.

  • Lawrence Livermore National Laboratory. Enhanced Hydrogen Production from Subsurface Mineral Deposits by Organic Acids and Catalyst Stimulation with Novel Optical Fiber Monitoring (Fiber-OACS) - $1,000,000. Lawrence Livermore National Laboratory (LLNL) is developing chemical stimulants to increase the rate of hydrogen production by accelerating the breakdown of minerals. LLNL is targeting short-chain organic acids that can both break down minerals while also recovering other critical minerals. The team is also evaluating whether other transition metals could catalyze geologic hydrogen production.

  • Los Alamos National Laboratory. Geochemical and Hydromechanical Stimulation for Reaction Acceleration (GeoHydRA) of Serpentinization for In Situ Hydrogen Production - $1,300,000. Los Alamos National Laboratory (LANL) is developing a method to increase the production rate of stimulated hydrogen through promoting hierarchical cracks in reactant rock formations. The technical approach includes laboratory experiments and numerical modeling to combine and couple geochemistry, geomechanics, fracture mechanics, and porous media flow. The proposed work would enhance the injection design and fluid chemistry to ensure that hydrogen production rates do not decrease quickly over time, as prior laboratory experiments and numerical modeling have suggested.

  • Massachusetts Institute of Technology. Towards Efficient Geological Hydrogen Production: Rate Determination, Control and Reactor Development - $1,300,000. Massachusetts Institute of Technology (MIT) is developing a laboratory reactor that will test many parameters and variables for geologic hydrogen production, such as temperature, pressure, and fluid composition. MIT’s customized reactor would utilize artificial intelligence, allowing for rapid screening of different parameters that can affect stimulated hydrogen. Since one of the largest hurdles in pioneering geologic hydrogen stimulation is the slow reaction rate between rock and water, the team will focus on identifying methods to increase the rates, yields, and user control over the reaction.

  • New England Research. Accelerated Mechanical Promotion (AMP) of Serpentinization for Hydrogen Production - $1,500,000. New England Research is developing a method for environmentally safe self-propagating fractures to stimulate geologic hydrogen. The team will monitor the creation of fracture networks and how fractures can propagate within a rock under a variety of physical or mechanical stimuli. Optimizing the self-propagating fractures can dramatically increase reaction rates in iron-rich host rocks to produce economic amounts of hydrogen.

  • Texas Tech University. Enhanced Hydrogen Production through Chemo-Bio-Physical Stimulations – with a View to Pilot Development - $1,620,000. Texas Tech University is characterizing rock samples from mining sites with diverse lithologies to develop the chemical, biological, and physical means to stimulate geologic hydrogen across different types of iron-containing rocks. Testing will include studying the effects of metal ion catalysts and the effectiveness of biological stimulation methods on increasing the reaction rates of hydrogen production. The team will optimize the chemical, biological, and physical stimulation of hydrogen-generating rocks to maximize geologic hydrogen stimulation.

  • 39 Alpha Research. Enabling the Discovery of H2 Producing Systems with Large-scale Chemical Cartography - $1,569,500. 39 Alpha Research is developing a water-rock-gas modeling product for users to determine the hydrogen potential of drill sites and recommended stimulation techniques. The models will aggregate results of water-rock-gas systems to aid in predicting geologic hydrogen potential from naturally occurring and laboratory water-rock-gas systems across a diverse range of compositions and reaction conditions. The technology would help tie together laboratory-scale models with future studies on rock formations.

The second—Exploratory Topic H: Subsurface Engineering for Hydrogen Reservoir Management—focuses on technologies relevant to the extraction of geologic hydrogen. The following teams will work toward improvements in subsurface transport methods and engineered containment, reservoir monitoring and/or modeling during production and extraction, as well as assessing the risk of hydrogen reservoir development:

  • Eden GeoPower. Engineered Geologic Hydrogen Battery for Long-Term Energy Storage - $500,000. Eden GeoPower is developing a subsurface battery technology that takes advantage of the reversible chemical reactions of iron in ubiquitous iron-rich geologic formations. The subsurface battery would operate as a long-duration energy storage solution by utilizing excess grid energy to reduce spent iron into usable iron for multiple cycles of hydrogen production.

  • Lawrence Berkeley National Laboratory. Cyclic Injection for Commercial Seismic-Safe Geologic H2 Production (CyclicGeoH2) - $2,000,000. Lawrence Berkley National Laboratory is developing a cyclic injection strategy to create fractures, stimulate geologic hydrogen production, and ultimately transport the produced hydrogen back to the surface. The approach involves multiscale numerical modeling, laboratory tests, and field characterization to develop and test the proposed technology using rock samples from Montana and other sites. Through high pressure, high temperature testing, the system will be optimized for hydrogen flow and maximum extraction.

  • New Mexico Institute of Mining and Technology. Subsurface Engineering Solutions and Management for Sustainable In-Situ Hydrogen Production and Economic Extraction - $1,200,000. New Mexico Institute of Mining and Technology is developing subsurface engineering approaches for geologic hydrogen reservoir management, including ways to mitigate the risk of induced seismicity and hydrogen leakage. In addition to conducting laboratory experiments to explore hydrogen generation rates and transport using steam, the team will test methods to minimize rock volume expansion and to identify ecological indicators of hydrogen leakage. These technologies could predict, model, and prevent harmful side effects associated with enhanced stimulation of hydrogen generating mineralogical processes.

  • Texas A&M Engineering Experiment Station. ULTRA-H2: Reservoir Management of Natural Hydrogen from Ultramafic Rocks - $1,500,000. Texas A&M Engineering Experiment Station is developing a method using modeling and experimentation to determine the behavior of a large-scale geologic hydrogen reservoir based on laboratory-scale data. The proposed approach would combine established reservoir characterization, exploitation, and management methodologies. Using laboratory investigations of a range of temperatures, pressures, and chemicals associated with field site rock cores, the team will develop models that can predict how to maximize extracted geologic hydrogen and minimize losses.

  • University of Southern California. Multiscale Characterization, Transport, and Mechanics for Enhanced H2 Recovery and Reservoir Management - $1,000,000. The University of Southern California is developing geologic hydrogen production and extraction techniques by utilizing industrial oil and gas methods. The proposed technology would be a modified version of the Huff-n-Puff process, which is practiced for shale gas recovery. Multiple process scenarios would be used to optimize the generation, accumulation, and extraction of geologic hydrogen. Laboratory studies on rock cores would be explored over multiple length scales and modeling would be used to determine how large-scale reservoirs will interact with this production method.

  • University of Texas at Austin. Foam-Assisted Enhanced Hydrogen Recovery (EHR) - $1,000,000. The University of Texas at Austin is developing a foam injection approach to extract geologic hydrogen. Conventional fluids like water or steam may present challenges for extracting hydrogen because of the insolubility of the hydrogen gas and bubbles being trapped. Instead, the injected foam sweeps, captures, and extracts clustered hydrogen bubbles from mineral surfaces to enable higher recovery efficiency and transport. The project team will design, synthesize, and characterize foam compositions for optimal stability and hydrogen uptake behavior in the reservoir.

In addition to these 16 projects, Argonne National Laboratory’s Systems Assessment Center is also set to receive funding to develop a methodology for Life Cycle Analysis for geologic hydrogen via the Greenhouse gases, Regulated Emissions, and Energy use in Technologies (GREET) model. The GREET model is widely used for assessing the energy consumption, greenhouse gas (GHG) emissions, criteria air pollutant emissions, and water consumption of various energy, material, and vehicle technologies. Also, the Inflation Reduction Act specially calls for the GREET model to be the basis for determining GHG emissions of hydrogen production projects for financial incentives.



Essential work We really have no current authoritative evaluation of what the processes are, and hence the size of the resource, or whether or to what degree it is self relenishing.
We have spotted some places where it happens, but there may be others.

We can say that to date as a resource it has passed every hurdle, although of course that does not guarantee the remaining ones.

As for cost, it is pretty clear that the cost would be vey low.

We are going to know one heck of a lot more within the next two years, as the data from current tests come in.


Not disappointing per se, but if the government is spearheading this then we are doomed to a morass of regulation, permitting, and environmental assessment. Do we think that fracking, lithium extraction, tar sands, and some kinds of LNG would exist if we allowed government agencies to hold our hand and guide our nose to non-success, economic failure, energy scarcity and misery. Many think that it is better to be green and poor -than- rich and dirty, not realizing that wealth unlocks technology and solves all problems even if we need to take the road of make-a-mess then clean-it-up. We can only hope that private investigations and development is happening under the radar and that a means of distribution will be encouraging enough to all parties such that there will be investors and serious mock-up projects. It seems we haven't heard much out of China to try to be 'first' to develop and use -- worrying that this is not gaining much interest and that perceived energy abundance is not being appreciated.


Hi Jer

Pretty much at the front of the pack for permitting and assessing geologic hydrogen is France, not renowned for light touch regulation!

I do not share your predeliction for laissez-faire, as it so often means unloading the real costs on someone else.

It is not cost free to pollute and damage health, it is just that the costs are borne by those suffering them, whîlst illegitimate profits are made by those who have passed the parcel for those costs.

Adam Smith et al knew all about such, essentially anti-capitalist rentier behaviour, so the supposedly capitalist credentials of those advocating laissez-faire seem not to withstand impartial scrutiny


If it is Friday, it must be Albania!:

Another substantial deposit found.
