Clean Energy



Stand-alone power plants are specifically built to provide industrial scale clean energy for electricity supply.

A hydrogen production facility is built alongside a power plant facility using one or more hydrogen capable gas turbines with associated equipment. Heat recovery steam generators (HRSG) are also typically utilized to gain further output from the same source of fuel.

Stand-alone projects are either using only hydrogen as a fuel, or a mixture of hydrogen and natural gas (methane) depending on the turbine capability.
Combustion of hydrogen fuel in a gas turbine creates heat and water plus a small amount of NOx below published threshold requirements.

All power plants are designed to project requirements for electrical output (MWe), based on the type of gas turbines to be used and the type and quantity of feedstock from which we generate the gases. Based on this information, the hydrogen production facility is then designed to suit.

With H2 First Fuels technology much smaller sized gas powered stand-alone projects become commercially feasible. Of course once the scale of project is increased, the project IRR is also increased.

Hydrogen Only Power Plant

With a hydrogen only power plant the gas turbines run on 100% hydrogen fuel.

Once the feedstock has been gasified and the gases separated, the hydrogen is sent to the gas turbine,

the CO2 is liquefied and sold as pure product into various industries. The methane and CO are returned

into the hydrogen facility for internal power requirements, or sold on.

The hydrogen facilities can also be designed to use hydrogen fuel cells for its internal power requirements.

Hydrogen Only Key Points

Minimal feedstock required
Lowest possible emissions model
CO2 is liquefied to be sold as a separate product
Project financial returns tend to be higher due to maximum fuel efficiency

Hydrogen & Methane Power Plant

With the H2 First Fuels system, an external supply of natural gas is not required. The fuel mix of hydrogen and methane is made in the same facility from the same feedstock. This has a huge benefit on operating costs.

Methane (Natural Gas) has less calorific value than hydrogen, so typically with less hydrogen being used by the turbine, more feedstock is required to generate the fuel required. The system is programmed to increase the amount of methane produced from gasification. Once the feedstock has been gasified, the gases are then separated. This results in hydrogen, carbon dioxide, methane, and a very small amount of carbon monoxide.

A percentage of the hydrogen or gas is then sent directly to the gas turbine to meet its H2 fuel requirement. A small percentage of hydrogen or methane (less than 2%) is returned to the Hydrogen Facility as fuel for its internal power requirements, with the rest being fed into the Sabatier tower with the all of the CO2, CO, and remaining H2.

By using a Sabatier process following gas separation, the hydrogen is combined over nickel catalysts with the CO2 to form methane. The fact that the gases being provided have zero impurities allows this process to work efficiently without extra purification and cost. The methane that was produced and separated following gasification then mixes with the methane from the Sabatier process to provide the required methane fuel for the power plant gas turbine.

The Sabatier process also generates water which will be returned into the water stream being used for the gasification process.

Hydrogen & Methane Key Points

More feedstock required than a 100% Hydrogen Power Plant
All CO2 is used to make methane, no other CO2 solutions are necessary
Power Plant is not affected by market natural gas prices
No external natural gas supply is required

bolt-on upgrades to existing thermal power plant

H2 First Fuels technology can be installed into existing thermal power stations to give the following benefits:

Enables Power Station to produce cleaner energy without burning coal
Significant reduction in emissions
Much higher coal to electricity conversion
Low grade coals can be used
Coal does not need to be dried first
Reduces or removes desulfurisation, denitration, and dust removal costs
Coal supply requirements greatly reduced, lowering operating cost
Potential carbon credits advantage
Power Station meets environmental targets for decades to come
Carbon tax costs avoided
Allows station to continue until needing full upgrade or replacement

option 1 - use existing burners/boilers

Supply H2 & CH4 fuel to the burners/boiler instead of coal dust to drive existing steam turbines
Gas lines will replace coal lines
Boiler may need re-configuring/replacing

option 2 - replace burners/boilers

System replaces burners/boilers with similar footprint
Power Station replaces Steam Turbines with Gas Turbines
