What is Gas-to-Power?

Gas-to-power technology generates electricity from various gas fuels, such as natural gas, biogas, landfill gas, LPG/propane, and flare gas. This highly efficient process converts gas into electrical energy while simultaneously capturing thermal energy (cogeneration) for additional heating or power generation.

About Natural Gas Systems

Natural gas is a fossil fuel composed primarily of methane. Despite being a fossil fuel, natural gas is considered the cleanest option among its counterparts. Its combustion produces lower sulphur dioxide, nitrogen oxides, and particulate matter emissions than coal-fired power plants.

Because of these attributes, natural gas is a compelling alternative to coal-generated grid electricity, particularly for businesses aiming to reduce their environmental impact. By transitioning to natural gas-based energy systems, companies can significantly lower their carbon footprint while maintaining a reliable energy supply. Its versatility and cleanliness make it a valuable transitional energy source as societies rely more on renewable energy.

About Biogas Systems

Biogas is produced through the anaerobic digestion of organic materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, or food waste. Unlike natural gas, biogas is a renewable source of energy that helps manage waste and produces energy without additional carbon emissions.

Biogas systems are well-suited for industries and facilities that generate significant organic waste.

Types of
Gas-to-Power Solutions

SustainPower's continuous gas-to-power solutions cater to clients aiming to minimise their carbon footprint by efficiently utilising organic waste streams or replacing coal consumption with natural gas. These systems support sustainability and present practical ways to reduce emissions.

Our highly efficient, world-class co-generation packages are designed for long-term use and can handle both constant and varying loads in island, island-parallel, or grid-parallel modes. They are also well-suited for combined heat and power (CHP) generation, allowing businesses to achieve significant savings and rapid payback periods by boosting power and heat efficiencies in industrial processes. Combined heat and power generation can utilise up to 90% of the energy within gaseous fuels, making it a highly efficient solution for energy conversion.

Cogeneration uses an engine's heat energy to generate electricity and heat simultaneously. It is a highly efficient form of energy conversion that, when performed with gas engines, can achieve considerable energy savings compared to purchasing electricity and gas separately from the utility.

Efficiency of a CHP Plant

CHP plants offer a highly efficient power generation process that utilises nearly 90% of the energy in a gaseous fuel. This high efficiency is achieved by harvesting the mechanical energy from the generator and the thermal energy from the combustion process.

Benefits of a CHP Plant

Combined heat and power plants allow the productive use of otherwise wasted heat released by the engine's water jacket and exhaust. When compared to importing electricity and using boilers to generate heat, the benefits of a CHP include:

Savings on total energy costs for the user.
Improved efficiency of fuel use.
Reduced emissions and a reduced carbon footprint.
Independence and security of power supply.
The opportunity for carbon credit accumulation.

SustainPower, in partnership with Pramac and Waukesha, has introduced rich-burn industrial stand-by gas generators to the African market, providing customers with a state-of-the-art solution for reliable, efficient power. These robust engines, manufactured in the USA and being a global leader in generator manufacturing, deliver the economical operating costs of a gas genset alongside the technical load-acceptance capabilities required for stand-by and prime power applications. This synergy means businesses now have a reliable emergency stand-by solution that can also function as an efficient peak-shaving unit, generating proactive cost savings and protecting against unexpected power outages.

Peak Shaving

Peak shaving is a strategic process that helps industrial and commercial customers reduce electricity usage during peak tariff periods, which can significantly lower energy bills. During these periods, clients identified as large consumers temporarily reduce their power consumption through production scaling or by activating on-site power generation systems. SustainPower’s range of rich-burn industrial stand-by gas generators offers clients the flexibility to maintain stable production levels without disruption during these high-demand intervals. By doing so, these generators help businesses maintain consistent production and navigate peak tariff periods without the costly effects of reducing operations.

Prime and Stand-by Power

  1. Prime Power:

Prime power serves customers without utility power connection or access to reliable utility power who often experience long-term outages. Under these conditions, prime power gensets provide continuous power at varying loads, with the operating hours not restricted yearly, provided they remain within agreed operational guidelines and maintenance intervals prescribed by the manufacturer.

  1. Stand-by Power:

Stand-by power caters to customers with regular access to utility power but need a dependable solution for emergencies. During sudden power outages, stand-by gensets offer immediate emergency power for a limited period, ensuring critical operations can continue without disruption. These generators are designed to provide swift and efficient support when required, safeguarding against productivity losses during unexpected outages.
