Renewable Energy: Biofuels

Bioenergy - Siemens USA

Process Instrumentation and Analytics

Providing a future-proof source of electricity and contributing to lower CO₂ emissions, power produced from biomass is becoming more economically viable. The interests of operators and investors, on the one hand, and those of utilities and grids, on the other, are becoming more closely aligned. This is because ensuring a stable power supply as well as the financial success of the power plant are common goals.

Biogas Overview

Biogas plays a significant role within the renewable energy sector, with particular emphasis on the economy of biogas plants. Siemens can help you make the correct choices for measurement solutions for temperature, pressure, flow, level and gas composition.


Temperature must be monitored whether in the fermenter or in the heat flow volume produced by the CHP plant.


Siemens offers rugged pressure transmitters for pressure and flow measurements. 


Various level transmitters are available for different applications within the biogas plant and Pointek level switches can be used to protect pumps and prevent overflows. 


SIWAREX weighing and batching systems enable weighing tasks to be integrated across the plant.


Magnetic flowmeters are suitable for measuring the substrate in pipelines and energy calculators can measure the heat supply.


Continuous gas analyzers monitor the composition of baseous components in the fermentation process.

Biodiesel Overview

Pressure, temperature, flow, and filling/limit levels must be monitored at various points in a biorefinery, whether for dosing, for transesterification, or for processing of glycerin. Process integration via PROFIBUS or HART communication provides important information for online monitoring, diagnostics (asset management), and predictive maintenance.

Bioethanol Overview

Glucose (such as in sugar cane) or starch from plants such as corn can be converted into ethanol and other alcohols of any desired concentration by means of fermentation and distillation. 


Even in the first process step of raw materials handling, we use precise processes to support delivery, weighing, analysis, and storage of feedstocks such as corn, sugar cane, vegetable waste, wood, or straw. This, of course, also applies to residual materials and by-products, which can be further marketed as, for example, animal feed or fertilizer.
