Hydrogen 100
100% HYDROGEN POWER…
For a modest uplift in capital cost - and no loss in output - NPV can generate 100% power output from waste-derived hydrogen.
100% HYDROGEN POWER…
GCORE converts waste into gaseous fuel – synthesis gas (syngas) – typically 45% volume CO and 40% H2.
Using standard hydrogen “water gas shift” (WGS) reactors, steam (a by-product of turbine and gas cooling & hydrogen turbine exhaust) is added to the syngas causing the following reaction:
CO + H2O → CO2 + H2
Raw WGS-treated hydrogen contains CO2, water moisture and atmospheric nitrogen. The CO2 and water moisture are removed in a small absorption tower that extracts 99% of the CO2 from the raw hydrogen, and all the H2O.
The CO2 is reserved (see below), the recovered hydrogen added back to the ~40% H2 already present in the syngas.
Post-treatment, the hydrogen is 88% pure, the remainder being atmospheric nitrogen and trace CO2. Since it’s only the hydrogen that fuels the turbines, we call it Hydrogen 100.

ZERO EMISSIONS
Inert nitrogen and trace CO2 pass through turbines in vastly smaller quantities than are present in air. Process is carbon-neutral/negative.
CAPTURED CO2 - WHAT HAPPENS TO IT?
Captured CO2 is 99% pure - carbon capture has both environmental benefits & commercial applications:
Carbon Credits – where applicable/available: Sequestration – as it is in its raw state, pressurised and pumped into abandoned mines or salt caverns; mixed with soil for reabsorption – in conjunction with planting programmes – and numerous other agricultural applications. As a carbon NEGATIVE business, NPV can “sell” carbon offset credits on various exchanges, where permitted.
As a commercially valuable commodity – CO2 has a surprisingly large number of applications in industrial processes such as steel production, fire suppression, cooling, “gas-lift” in oil & gas production, packaging, etc. There is a global market for industrial CO2, UK pricing currently £41/tonne (May 2026)
With further purification, CO2 can also be extensively used in food production/manufacturing; dry ice, packaging, refrigerated transport, processing, carbonating drinks, and even as an essential component in decaffeinating coffee! Food grade CO2 achieves a higher commodity price and requires additional capex at the plant.
NOT JUST ELECTRICITY
Doing the “right thing” has commercial benefits
Nothing is wasted in the GCORE process - every stage produces commercially-valuable by-products - and contributes to protecting the environment
