What if all natural gas wells could produce clean energy, while capturing their own carbon?
Our novel process enables the rapid and cost-efficient scale-up of low-carbon hydrogen production by changing how we exploit abundant global natural gas, geothermal and biogas resources. It adapts how we consume these energy resources, to meet the growing demand for hydrogen driven by the energy transition, while overcoming the climate challenges faced by current production methods.

The Problem

- There’s a critical need to balance economic prosperity, energy security and environmental protection. Global energy demands conflict with society’s environmental goals, creating an energy-climate conflict; green energy and no carbon versus cheap, reliable, energy security, at volume
- Oil & gas production and consumption remains high to feed our demand for energy
- The greenhouse gases (GHG) produced create climate damage from hydrocarbon energy consumption
- For a successful energy transition, clean energy is required at volume with carbon captured at source
- The downstream, atmospheric carbon capture and storage (CCS) processes consume commodities and high process energy and require new, high-cost CO2 infrastructures, while capturing a small % of total carbon volumes in the oil & gas produced
- Biogas is currently upgraded to biomethane, producing CO2 when burned, which will lead to limitations in the future use and disposal of biogas
- Climate driven policies are mandating reductions in the use of CO2 emitting fuels
- A more immediate, direct & effective route to Net Zero is required to reach our climate and environment goals
- To accelerate the energy transition, cheaper and higher volumes of both hydrogen and carbon capture are needed
Our Solution

- Our patent pending technology exploits methane reserves (Natural Gas and Biogas) at source in a climate-beneficial way, and so future-proofs these assets against emerging environmental regulations, offering a more effective and immediate path to carbon footprint reduction.
- The Metharc tool when placed deep in a natural gas (or geothermal) well, is provided with free compression, heat exchange, a supercritical environment, and thermal insulation in a wellbore acting as a pressure vessel. This significantly reduces the process energy input required for the methane reformation.
- The reformation (gasification) of methane to generate hydrogen and the hydrogen separation both occur inside the deep-set wellbore tool, allowing for a more accessible and controllable process with fast and accurate tool heating, using a tool design that is both modular and highly customizable.
- Metharc enables Natural Gas, Geothermal and Biogas companies to become hydrogen production and carbon capture leaders, taking advantage of their existing licenses with fewer permitting barriers, less complex value chains and proven logistics.
