This study will evaluate the technical, commercial, financial, and environmental viability of utilizing Langson Energy’s 5 MW Total Flow Generator to make more efficient use of the geothermal resource at Olkaria. Upon the successful results of the study, KenGen and LEI will have the opportunity to install a number of additional units in the more than 275 wells which will optimize power plant efficiency and greatly impact the electric footprint in the country.

Langson Energy‘s Senior Engineer, Dr. Ron DiPippo, will be the Geothermal Expert on the project working with a team of 10 other experts.  As Author of 4 major books including, Geothermal Power Plants: Principles, Applications and Case Studies, Dr. DiPippo is the foremost world authority and consultant on Geothermal Power Plants. In addition to Dr. DiPippo’s experience with the Olkaria Geothermal Power Plant in Kenya, he has worked in many geothermally active US states and countries around the world.  Dr. DiPippo states, “The advantages of a thermodynamically equivalent Total Flow Generator will lie in its simplicity, lower capital cost, ease and rapidity of installation, reliable operation, lower cost of electricity, and ability to operate on lower-temperature reservoirs, compared to either flash-steam or binary systems, provided an isentropic efficiency of at least 75% can be achieved in practice.”

S Dakota Ethanol Plant Steam Machine Demonstration

Langson Energy Inc. (LEI) awed over 100 onlookers over a 2-day period as they invited city officials, ethanol plant operators and owners to witness how they use waste steam pressure to make green electricity at an ethanol plant in South Dakota. This is the first time this award-winning company’s latest green steam technology has been installed in the United States. Langson’s low cost, scalable clean energy production units are significant to the global energy landscape because traditional turbines have difficulties with saturated steam, but the Steam Machine seamlessly converts it to clean power.

It took only 3 days and a few personnel to install a 250kW Steam Machine in the ethanol plant’s boiler room.   The plant currently produces a million gallons of ethanol a year and planes to increase their production to 1.5 million gallons per year. It is important to plant management to increase their sustainability by improving energy efficiency, to reduce emissions and reduce their energy costs.

The LangsUnloading the Steam Machineon Energy Steam Machine is exactly what they need to help them achieve these goals.

There are several opportunities in typical ethanol plants to take advantage of making low-cost green electricity with Langson Energy’s pressure-reduction generators:


Often natural gas comes into a plant at a high pressure that needs to be dropped to a useable, lower pressure level which can be done by circumventing the typical pressure reduction valve (PRV) with Langson Energy’s Gas Pressure Letdown Generator (GLG).

One of the greatest advantages of using the GLG is to provide cooling from the natural Joule–Thomson effect when the pressure of a gas is reduced (like the cooling that happens when a can of spray reduces the pressure of its contents). This cooling may even eliminate the need for refrigeration equipment and the consumption of more energy required by refrigeration for plant processes or air conditioning.  Did you know ethanol plants also manufacture dry ice from the captured CO2 released during the fermentation process?

In dry milling ethanol plants, the entire grain is first ground into “meal” which is slurried with water to form a “mash.” The mash is processed in a high-temperature cooker (boiler) to reduce bacteria levels ahead of fermentation. This presents another opportunity – namely, Langson Energy’s new Steam Machine like the machine first installed in South Dakota this week.  After some experience with the 250 kW Steam Machine, this ethanol plant plans to  generate at least another 2 MW (8 times more) of green electricity.

Founder and inventor, Richard Langson’s insight into compression and expansion technology was developed while building and driving his super charged race cars. His fuel car, the “Texas Ranger,” still holds Steam Machine in Ethanol Plant Boiler Rooma world record. Langson went on to win the 1993 IHRA World Championship by beating “Big Daddy” Don Garlits. This drag racer brings the same world champion mentality to the world of energy efficiency.

The Steam Machine is the third product LEI has introduced from its steam, ORC and gas twin screw expander line. Langson Energy’s technology is integrated with proven components that have a history of reliable, robust, low-maintenance performance. Langson has solved the challenges of expensive steam turbine solutions for generating power. Traditional turbines have been the accepted method for generating power from steam pressure for many years. However, high capital costs and difficulty in handling wet steam have proven to be significant hurdles to running saturated, contaminated steam, two-phase fluids and geothermal brine. The Steam Machine has significantly lower capital costs than all other steam turbines. The LEI Gas Letdown Generator (GLG), developed earlier, won the bronze Edison Award, for “Best New Green Technology.” The GLG converts natural gas letdown pressure to power like the Steam Machine converts various steam types to power and Langson’s “ORC” Organic Rankin Cycle produces power from low temperature waste heat. In addition, the product line has been approved by the Department of Defense for use on military bases. Ethanol Plant Demo Site January 2016

Richard and Chris at Edison Awards

Carson City-based Langson Energy recently received the prestigious Edison Award, Bronze for Best New Green Product for the Langson Energy Gas Letdown Generator. Chris Coté, executive vice president, and Richard Langson, founder and innovator, represented the company at The25th annual Edison Awards, on April 26 in NYC.

The award was in recognition of the Langson Energy’s Gas Letdown GeneratorTM which converts wasted kinetic energy in gas pipelines to clean, base-load power with the lowest capital and lowest operating costs of any generation technologies – with no carbon emissions.

“This is just the type of innovation that will lead to the resurgence of our economy,” stated Rob Hooper, executive director of the Northern Nevada Development Authority. He added, “Entrepreneur’s like Langson in developing new technologies is a very effective way to move this economy forward. Our congratulations go to
Langson Energy for being a leader in this new field.”

Langson’s experience with compressors in his top fuel dragster that helped him win the 1993 IHRA World Championship, led him to modify this technology to develop a low-cost generator that could handle conditions that caused other generators to fail. Research confirmed his theory and the Langson GLGTM was born.

The generator was developed to provide the world with green electricity that utilizes wasted or renewable energy to generate low-cost, un-subsidized, clean, sustainable, 24/7 distributed power by converting wasted pressure to green power. Providing value without subsidies is a primary goal for Langson Energy. It also offers the potential to become the first low-cost, distributed source of emergency power.

“Our Gas Letdown GeneratorTM (GLG) will revolutionize the economics of base-load distributed green energy. For very little cost per kW, GLGs can produce 1MW to 100MW for subsidy-free CapEx pay back of just 1 to 3 years,” exclaimed Richard Langson, an innovator who saw an opportunity to use energy wasted, not only in gas pipelines but in other forms of wasted renewable pressure. He envisioned a robust generator that made electricity from kinetic energy in wasted pressure.

“From currently wasted energy in US cities alone, the GLG could provide enough clean electricity to power over 10 million homes – that’s using only the pressure, none of the gas,” explained Coté. She added, “Perhaps more important is the potential of utilizing the energy already stored in underground pipeline and storage domes as a source of emergency power during times of natural disasters or national crisis. If GLGs were on letdown stations across the nation, terawatts of distributed emergency power would be available immediately utilizing existing infrastructure.”

Langson Energy has welcomed visitors to watch the prototype run in its R&D shop in Carson City since 2010. The many gauges display the details of the electricity generated with variations in pressures, temperatures and flow rates. Data runs are maintained and analyzed by staff and third party organizations. Langson Energy has also built a mobile unit which is being offered to potential users such as governments, universities and research facilities who want testing on their own applications.

Mar 2012 – GLG Testing Completed at Third-Party Lab

Carson City, Nevada (March 27, 2012) – The Langson Energy Gas Letdown GeneratorTM has completed testing in Elite Energy’s Test Lab for natural gas letdown power generation. The GLG utilizes helical screw technology to generate power from natural gas pressure reduction. It is designed to work in conjunction with existing natural gas pressure reduction stations as a means to capture the energy contained in the pressurized gas.

LEI Test Cell

Research, development and operational testing previously performed by Langson on the GLG had been performed exclusively using compressed air. Langson’s customers requested an independent test using natural gas in order to simulate conditions within the environment being considered for implementation.

A test protocol was developed by a major gas and electric utility in order to demonstrate power output curves from varying gas pressure and flow conditions and gas inlet and outlet temperatures.

Elite Energy Systems, Inc of Carson City, NV, was asked to design and construct a high pressure closed-loop natural gas test environment capable of conducting tests simulating a range of pressures and temperatures and to measure the power output capability of the Gas Letdown GeneratorTM. Designed around equipment supplied by Langson Energy and incorporating a comprehensive collection of instrumentation, safeties and controls, the test loop was completed, tested and became operational in mid March 2012.

“The Gas Letdown GeneratorTM performed as expected and no specific operational issues were encountered while operating on Natural Gas. The Test data shows consistent and predictable trends. The testing indicates that the outlet temperature can be confidently predicted based on inlet conditions and design power can be confidently predicted based on mass flow and pressure ratio,” says Peter Palmer, Elite’s Test Engineer.
