The company’s primary commercialised technology, the It’sFresh! Filter, delays the ripening process of produce thus extending shelf life.

GreyRock’s industry leading Direct Fuel Production™ platform enables the transformation of a methane rich steam (coal mine methane, flare gas, bio-gas, natural gas or natural gas liquids) into premium diesel fuel that can be used locally or can be easily transported to market.

HPNow is a Danish based developer of distributed hydrogen peroxide produced via electrochemical synthesis. Using only water, air and electricity as inputs, the systems provide autonomous, safe, eco-friendly solutions for organic wastewater applications.

Hydrogen-Refueling-Solutions (“HRS”) designs and manufactures turnkey hydrogen refuelling stations for on-road mobility, from passenger cars to heavy duty vehicles.

Hydrogenious is a Germany-based company that has developed disruptive technology that allows for more efficient transportation of hydrogen in liquid form.

The company’s method of combining a diesel-like fluid with hydrogen avoids the need for compression and cooling.

HyET Hydrogen is a Netherlands based producer of electrochemical hydrogen compressors, capable of compressing up to 1,000 bar. The technology has the capability to compete with mechanical compressors in numerous applications, and is an essential building block for low cost, reliable, low maintenance hydrogen.

In partnership with a listed oil and gas major, the company has successfully demonstrated its technology in a hydrogen refuelling station (“HRS”). The mission of the company is to replace current mechanical compression in HRSs, thereby greatly improving station reliability, lowering capex and operating costs.

Hystar is a Norwegian company that has developed unique and proprietary cell architecture for PEM electrolysis that enables a step-change in performance, efficiency and cost reductions in the production of hydrogen, through the ability to use a thinner membrane in the membrane-electrode-assembly (MEA).

Based in Sacramento, Infinium offers an industry leading, commercial ready electrofuels solution that can decarbonize the transportation industry today using existing infrastructure. Infinium’s Electrofuels™ are a net-zero carbon alternative to existing liquid fuels that can immediately “drop in” and be used in plane, ship and truck fleets.

Insplorion has developed a Nanoplasmonic Sensing technology (NPS), to enable precise, robust and selective measurements for a wide range of applications, including Air Quality, hydrogen and battery chemistry sensing.

Plug Power is a leading provider of hydrogen engines and fuelling solutions enabling e-mobility. The Company is leveraging its modular product architecture in foundational markets to rapidly expand into zero-emission on-road vehicles, robotics, and data centres.

Starfire Energy is a USA based leader in green ammonia synthesis and cracking. Starfire Energy’s ‘Rapid Ramp NH3’ ammonia synthesis technology produces zero carbon ammonia using only renewable energy, air and water as inputs. Starfire’s ‘Prometheus Carbon-free Fire’ system cracks ammonia back into hydrogen, providing an efficient means of green hydrogen storage and transport.

UHG is a US company that principally produces and distributes gaseous and liquid hydrogen.

The company currently operates a bulk hydrogen production facility, which has expanded to include a liquefaction plant, and has also developed technology to convert “impure” gaseous hydrogen into a clean useable product.

The company plans to deploy hydrogen refueling stations across the United States, ensuring the early deployment of infrastructure into this critical geography.

ZEG Power is a Norway-based developer of blue hydrogen production plants with integrated carbon capture. The simplified reforming process produces high purity hydrogen and separate high purity carbon dioxide, ready for utilisation and/or storage.
