TECHNOLOGY
The cultivation of energy crops for the purpose of producing biomass, results in a secure and consistent supply of feedstock for continuous and uninterrupted generation of renewable electricity.
Combustion Steam Technology has been the standard process for converting biomass feedstock using boilers to generate steam which is then fed to steam turbines in order to supply low emission electricity.
Anaerobic Digestion Technology has been widely used as a process for agricultural waste in order to release methanegas (biogas) which is then fed to gas turbines andresults in a carbon neutral supply of renewable electricity.
Gasification Technology has emerged as a viable alternative to combustion steam technology where a significantly higher levels of energy conversions are achieved using gas turbines and result in a carbon negative supply of renewable electricity
Combustion Steam
Combustion steam has evolved as the industry standard for generating low emission electricity. The system works to a fixed format rather than a fermentation or chemical process. There is no need for added external components to break down the wood biomass. The requirements for drying the wood biomass are significantly reduced as the system can absorb a moisture content of up to 20%.
Anaerobic Digestion
Anaerobic Digestion of agri waste such as chicken litter, sugarcane press mud, tapioca waste etc. to produce biogas which is used in GE Jenbacher gas engines to produce electricity. From the fossil fuel displacement created from the generation of clean electricity, the project methodology has been validated for carbon accreditation.
Gasification
Gasification incorporates a Bio crude process whereby wood chips enter a chamber heated to a very high temperature. The wood chips are disintegrated as they pass through the chamber as there carbon chain is broken down, resulting in the formation of syngas which provides the source of power for gas turbine engines.GE’s Jenbacher gas engine division is one of the world’s leading manufacturers of syngas-fuelled reciprocating engine.
