Langson Energy, Inc. was selected by Kenya Electricity Generating Limited (KenGen), producer of around 80% of the power consumed in Kenya, to conduct a green technology feasibility study for their Olkaria Geothermal Power Plant. KenGen has been searching for a specialized genset that can be installed upstream as a topping unit capable of accepting high pressure geothermal wellhead pressures to capture the waste energy and generate additional clean electricity. Representatives from KenGen and the United States Trade and Development Agency (USTDA), which will be partially funding the study, were in Nairobi, Kenya for this historic grant signing on April 27, 2017. “USTDA is pleased to facilitate new business partnerships between U.S. and Kenyan companies that can spur long-term, sustainable economic growth,” said Sub-Saharan Africa Regional Director Lida Fitts. “The adoption of innovative and cost-effective U.S. technology can help Kenya to meet its energy development goals.”
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.”
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 Langson 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 a 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.

Langson unveils system to put wasted pressure to use
by: John Seelmeyer
The curtain rises in Amsterdam next week on the second act of Richard Langson’s career as a creator of technology to generate electricity from energy that otherwise goes to waste.
Langson Energy Inc. will unveil technology that captures the pressure that’s released from natural gas pipelines as gas is prepared for delivery to individual customers. The company’s technology then uses the pressure to drive a generator.
With any luck, Langson expects to bring one significant contract home with him to Carson City from Gastech 2011, an international meeting of executives from the natural gas industry.
He’s accustomed to winning.
As a race-car driver and builder, Langson beat out the legendary Don “Big Daddy” Garlits for the International Hot Rod Association world championship in 1993.
The superchargers used in dragsters spurred the thinking that led Langson to create technology that uses waste energy from industrial applications to drive generators that produce electricity.
He sold his interest in ElectraTherm Inc., the company built around the heat-recovery technology, to an investor group a year ago.
The sale completed, Langson got to work on his next big idea in a nondescript shop building up a rut-filled, muddy lane at the north edge of Carson City.
His thought: Natural gas pipelines compress gas to 1,000 pounds per square inch to deliver it across the country. But pressures are reduced dramatically – sometimes as low as 2 pounds per square inch – when gas is delivered to homes.
Utilities traditionally have simply reduced the pressure through valves.
Langson Energy Inc., however, replaces the valve at the gas letdown station with a device that captures the pressure and uses it to drive a twin-screw generator to produce electricity.
The market? About 3 million letdown stations are located around the United States, Langson says, and European locations may be an even more attractive market.
A one-megawatt Langson Energy system with an installed cost of $1.6 million would pay for itself in less than two years if power is priced at 10 cents a kilowatt hour. And the payback doesn’t include any incentives. (Nevada doesn’t include power produced from recovered pressure in its definition of renewable energy; about half the states allow its use for conservation incentives.)
Because gas letdown facilities typically are located in urban areas, connections to the electric grid will be easy, Langson says.
Much as he hopes to come back from Amsterdam with a contract in his pocket, Langson also-is looking for utilities willing to give the letdown generation system a test. The company just manufactured a trailer-mounted unit, and Langson says he’s talking with several major utilities and Fortune 500 companies about taking it out for a test spin.
Financing the new company himself, Langson wants to create new jobs for Carson City, where his family has been at home for 60 years.
Within a couple of years, he expects Langson Energy will build a 25,000-squarefoot headquarters and research facility, and he expects the company could employ as many as 130 once it gears up assembly operations.
The company currently employs five, with a cadre of 16 consulting engineers across the country offering their advice.
