RedShift Energy, Inc.

RedShift Energy, Inc., is developing Hydrogen and Sulfur Recovery Technology (HSRT), an innovative plasma process that dissociates hydrogen sulfide (H2S) into hydrogen and sulfur, without carbon emissions. Conventional Claus-based Sulfur Recovery Systems miss the opportunity to recover hydrogen. Thermodynamically, H2S is the cheapest source of carbon-free hydrogen when paired with renewable electricity. HSRT employs patented modular and scalable systems that retain their economic advantage from upstream to downstream. Deploying this disruptive technology will effectively and economically process H2S, while reducing emissions of carbon dioxide from Steam Methane Reforming hydrogen production. HSRT will help companies meet environmental goals.


RedShift Energy, Inc., a privately held, Texas based corporation, is developing Hydrogen and Sulfur Recovery Technology (HSRT), an innovative plasma chemistry process that safely and effectively converts unwanted byproduct of the oil industry, hydrogen sulfide (H2S) into two commercial products – hydrogen and sulfur, without carbon emissions. The main operations are at the Warminster, Pennsylvania research and development facility.

Plasma Chemistry

Plasma is one of the four major states of matter. There is not a sharp boundary between gas and plasma: gas that contains positively and negatively charged particles, ions and electrons, and therefore is electrically conductive, is plasma.  When we control properties of gas with electro-magnetic fields, we work with plasma. Using electricity, it is possible to create plasma with very different properties: for example, hot plasma of electric arc used for welding and cold plasma in fluorescent lamps. Plasma can be used for control of chemical processes.


Replacing a Claus-based Sulfur Recovery System (SRS) with HSRT, when paired with a renewable source of electricity, will yield a zero-carbon process of recovering hydrogen.

When deployed upstream, HSRT helps reduce greenhouse gas emissions by enabling the safe recovery of associated gases.

Hydrogen and Sulfur Recovery
Golden Hydrogen

Clean Hydrogen from H2S

Today, refineries consume 25% of the hydrogen produced worldwide, particularly to remove sulfur from oil products. The oil desulfurization process converts sulfur-containing substances and hydrogen to hydrogen sulfide. Then, hydrogen sulfide is partially oxidized in the Claus process-based sulfur recovery units to sulfur and water vapor. HSRT enables the recovery of carbon-free hydrogen from H2S, that is thermodynamically an inexpensive source of hydrogen.

Hydrogen Opportunity

RedShift Energy HSRT is a proprietary method that builds on forty years of research and development. HSRT systems are modular and scalable and is economically viable from wellhead to refinery scale. A clear opportunity exists for the introduction of this disruptive technology that can effectively and economically process H2S. Recovery of carbon-free hydrogen from H2S will result in a reduction of carbon dioxide emissions during hydrogen production by steam reforming of hydrocarbons.

Hydrogen & Sulfur Recovery

HSRT uses a proprietary high-voltage low-current arc plasmatron to create a high-temperature zone that dissociates hydrogen sulfide and allows for the capture of hydrogen.  In HSRT this zone is small, but the gas flow velocity is high. This makes HSRT very compact in comparison with Claus units. Reverse vortex gaseous dynamics and special materials in the plasmatron enables long-term stable operations. Fine-tuned plasma and flow parameters make this process energy efficient and profitable.


Reverse Vortex Plasmatron

HSRT uses a proprietary reverse-vortex high-voltage low-current arc plasmatron to create a high-temperature zone that dissociates hydrogen sulfide and enables hydrogen recovery.

In HSRT this high-temperature zone is small, but the gas flow velocity is high. This makes HSRT very compact in comparison with Claus units.

Stable Operation

Stable long-term energy efficient operation is enabled by precisely arranged gaseous dynamics and plasmatron materials.

We identified materials that enable electric arc electrodes to operate for extended periods in H2S atmosphere.

Special Flow Dynamics

We are the experts in the formation of electric discharges in vortex and reverse-vortex flows. We obtained separation of sulfur clusters in atmospheric pressure vortex flow arc discharge. In this way, we shift chemical equilibrium of hydrogen sulfide dissociation and increase process efficiency.

Downstream Impact

HSRT allows recovery and recycling of hydrogen at a cost less than US $1/kg.

This process produces carbon-free hydrogen.

HSRT has a modular design for maximum operational efficiency and a small footprint.

Upstream Impact

High sulfur content prevents development of many reserves.  

Our technology allows for handling of hydrogen sulfide on-site and enables development of high sulfur content reserves.

Halliburton Labs Selected RedShift Energy
for Industrial Scaling Accelerator

RedShift Energy, Inc. is one of three companies selected by Halliburton Labs to participate in their clean energy accelerator over the next year, starting in June 2022. The RSE team has access to Halliburton's extensive global facilities and resources including engineering services, supply chain, and consulting to further scale and optimize RedShift's novel hydrogen production technology.


23rd World Petroleum Congress

RedShift Energy, Inc. was selected as one of the finalists for the Conoco Phillips Innovation Zone at the 23rd World Petroleum Congress, held in Houston, Texas from December 5-9, 2021. Innovation was the theme of the Congress, with companies representing over 70 countries in attendance. The Congress is held in cities all over the world, once every three years. It is the first time the Congress was hosted in the United States in over thirty years.

Dr. Alexander Gutsol and Howard Nelson introduced Hydrogen and Sulfur Recovery Technology (HSRT) to the attendees at the Congress on Monday, December 6, 2021.

Plasma Chemistry

Plasma is one of the four major states of matter, and was first described by chemist Irving Langmuir in the 1920s. Plasma can be artificially generated by heating or subjecting a neutral gas to a strong electromagnetic field to the point where an ionized gaseous substance becomes increasingly electrically conductive, and long-range electromagnetic fields can dominate the behavior of the matter.

Plasma and ionized gases have properties and display behaviors unlike those of the other states, and the transition between them is mostly a matter of nomenclature and subject to interpretation. Based on the surrounding environmental temperature and density, partially ionized or fully ionized forms of plasma may be produced. Neon signs and lightning are examples of partially ionized plasma.

The Earth's ionosphere is plasma, and the magnetosphere contains plasma in the Earth's surrounding space environment. The interior of the Sun is an example of fully ionized plasma, along with the solar corona and other stars. Positive charges in ions are achieved by stripping away electrons from atomic nuclei, where the total number of electrons removed is related to either increasing temperature or the local density of other ionized matter.

Ionization of gases can be accompanied by the dissociation of molecular bonds, though this process is distinctly different from chemical processes of ion interactions in liquids or the behavior of shared ions in metals. The response of plasma to electromagnetic fields is useful in many modern technological processes, such as ozone production or plasma etching.
