Biogas powered stirling generator for the developing world

In a very interesting development, Infinia Corporation announced that it has partnered with start-up Emergence BioEnergy Inc. (EBI) to develop an innovative energy system that will serve developing nations' rural communities who can make use of abundant biomass resources. EBI is led by Iqbal Quadir, founder of the highly successful company GrameenPhone, which started by providing telecommunications to the poorest, but rapidly grew into Bangladesh's largest operator.

EBI will start its project in Bangladesh and has developed a comprehensive energy supply strategy for serving low-income countries around the world. Key concepts are village ownership, the use of local biomass resources and decentralized energy production.

The project tries to tackle three well known energy-related obstacles for development in poor countries: (1) primitive biomass used for cooking and heating is highly inefficient and a killer in the kitchen claiming two million lives each year (earlier post), (2) the lack of reliable and affordable refrigerators prevents the development of efficient food and medicine markets where products need to be kept fresh and cool, (3) finally, the lack of rural electrification limits the opportunity for people to study, to connect to the broader world and to spend their time efficiently.
This opportunity has the potential to positively impact more people in more ways than virtually anything I've seen. - Iqbal Quadir, CEO of EBI, founder of GrameenPhone
The initial project involves the mass production of Infinia's 1-kilowatt (kW) free-piston Stirling generator with a thermal appliance. The generator will operate on methane gas produced by an anaerobic digester that converts livestock manure and agricultural wastes into combustible biogas. The product is highly versatile and can be adapted to other fuel sources, depending on the circumstances.

Stirling generators, cryocoolers
Infinia is the leading developer of free-piston Stirling generators ranging in sizes from tens of Watts to multiple kilowatts. The generators are especially well suited for critical power applications that require silent operation, high reliability, and long life with little or no maintenance. The free-piston technology is also applied in the development of cryogenic coolers and pressure wave generators that provide long-life, maintenance-free cooling for a variety of applications.

Stirling engines are highly efficient free-piston engines originally developed by Robert Stirling in 1816. The Stirling cycle uses a working fluid (typically Helium, Nitrogen or Hydrogen gas) in a closed cylinder containing a piston. Heated on one end and cooled on the other, the expansion and cooling of the gas drives the piston back and forth in the cylinder. The work performed by this piston-motion is used to drive a generator (in Infinia’s case, a patented linear alternator) or to create pressure waves to drive a compression process (animation, click to enlarge).

The cycle can be operated in reverse by using the generator as a motor to drive the piston. In this case, the continuous expansion and cooling of the working fluid caused by the piston motion creates a cooling effect. These types of systems are called Stirling coolers (also referred to as cryocoolers) and can maintain temperatures as low as 10 Kelvin (-263°C, and –442 °F):

The EBI strategy provides a platform that generates electricity on a sustainable basis from locally available fuel sources and provides clean, high quality heat to support additional income-generating opportunities for local entrepreneurs. The digester produces fuel for the Stirling engine and produces waste solids which can be used as fertilizers and fish feed. The Stirling engine will consume biogas from the digester and generate electricity and heat.

"Infinia's unique Stirling engine technology will enable us to provide an efficient and reliable energy system that the farmers and villagers can operate and maintain themselves," said EBI CEO Iqbal Quadir.

Infinia's reliable and maintenance-free 1 kW Stirling engine is being used in residential combined heat and power appliances expected to be commercialized in Asia and Europe over the next 18 months. Mass production of the 1 kW engine will help to ensure that the EBI product is affordable for Bangladeshi entrepreneurs and villages.

In a similar development aimed at increasing the rural poor's access to modern energy, a consortium of major UK universities, the US Los Alamos National Laboratory, a multi-national electrical goods manufacturer, an international charity and numerous universities in Asia and Africa launched the SCORE project (Stove for Cooking, Refrigeration and Electricity). The device will rely on the physics of thermoacoustic heating and cooling - a field of research that has resulted in such high-tech applications as devices to cool satellites, radars and to liquefy natural gas.
