Our Mission

 

"Deploying technology that makes 'Power without Pollution' a reality."

 

Safe, reliable power that doesn't compromise the environment: It's been our mission since the beginning.

 

Clean Energy Systems has successfully transitioned proven and reliable rocket engine combustion principles into a flexible and economically attractive energy generation system for our planet. CES technology enables cleaner and more efficient co-generation of power, steam, water, and CO2 and offers the world a new perspective on the way we assess the value of natural resources.

 

Our core competence allows us to precision engineer complex and intricate technology solutions that meet your needs, be it in combustion, partial combustion, heat transfer, or other applications. Among others, it enables us to precisely control the conversion of a wide variety of fuels with oxygen in oxy-combustion processes. Oxy-fuel combustion generates a drive gas composed of predominantly steam and CO2. This uniquely efficient process allows our customers to profitably utilize fuels that would otherwise be marginal or uneconomic for commercial energy generation. 

 

Facilitated through partnerships with our customers and shareholders and enabled by an exceptional research and demonstration facility, CES has developed and built a unique product portfolio. Centered around customized precision-engineered components, our portfolio encompasses 20 to 200 MW steam and CO2 generators, drive gas re-heaters, steam/water separators, pressurized heat recovery systems, 30 to 150 MWe expander turbines, and more. These solutions are ready to fulfill our customers' needs for zero emissions power, enhanced oil recovery, and the expansion of natural resource assets.

 

Clean Energy Systems Technology
- It's Rocket Science

Imagine harnessing the tremendous energy of the Space Shuttle! Over the past 18 years the California-based

 company, Clean Energy Systems Inc. (CES), has turned imagination into reality by enabling the same reliable, clean, and powerful principles to be used in everyday energy applications. 

 

The combustion of fuels still plays the central role in today's energy production systems. However, there are many negative side effects associated with traditional combustion methods, not the least of which is the emission of harmful air-pollutants. Envision a world in which energy demands are met with zero emissions, 100 percent carbon capture, and no NOx. CES is prepared to revolutionize the power industry by eliminating the trademark smoke stack and making Zero Emissions Power Plants (ZEPPs) the standard. 

 

With the increasing economical and ecological cost of energy and the enhanced oil recovery (EOR) industry's growing need for CO2 and steam, there is a clear demand for a new kind of energy generation system that will address these needs and more. CES revolutionizes the oil industry by providing CO2 where it's wanted, when it's needed and supplying steam to in-situ bitumen recovery without air emissions.

 

 

 

 

 

 

 

 

 

Platelets

A key difficulty in oxy-combustion is controlling the reaction, ensuring that the oxidizer and oxidant (fuel) mix to form a homogenous flame front, while avoiding hot spots or producing un-combusted product. To overcome this complication, American rocket and missile propulsion manufacturer Aerojet introduced and developed platelet technology for the fabrication of combustor injectors. Through the use of platelets, they were able to engineer a highly precise, efficiently mixed, and controllable oxy-fuel combustion mechanism.

 

Platelet technology provides solutions to difficult thermal and fluid flow problems in a variety of applications. In this unique technology, thru and partial depth patterns are chemically machined with photographic accuracy in thin sheets of metal producing "platelets." These individual platelets are in turn accurately assembled, or "stacked", and then joined by solid state diffusion bonding to form a monolithic structure containing internal passages. These passages contain precise flow control manifolding and metering features along with in-situ filters to preclude contaminant caused plugging or occlusion. Where multiple reactants or fluids pass through the platelet device, the diffusion bonded lands formed between the passages effectively isolate and segregate the flows. Following bonding, the platelet assemblies are machined and welded using conventional techniques to produce finished products or components of assemblies.

 

A prominent example of the application of platelet technology is the two-fluid, oxidizer/fuel injector face plate for the NASA Space Shuttle Orbital Maneuvering System Engine (OMS-E). This Aerojet-developed rocket engine sported a spotless, 100% reliability record over the 30 year lifespan of the Space Shuttle program.

 

Platelet technology plays an essential role in CES' oxy-fuel combustion systems - the heart of the CES' combustor, the injector, is a three-fluid platelet device. The CES platelet injector provides precise metering and mixing of fuel and oxidizer through hundreds of individual injection elements while providing the necessary cooling to assure long component life through the injection of water or steam.

 

Since the company's inception, CES has worked with the inventors of platelet technology, building our systems with guidance from the world's foremost platelet experts, a number of whom are among CES' original founders and current employees and consultants.

 

 

 

 

 
 

Oxy-Fuel Turbines

Clean Energy Systems gas generators are capable of producing drive gas at any combination of pressure and temperature. Therefore, they are ideally suited to tailoring drive gas generation to the inlet design conditions of combustion or steam turbines. This paradigm shift in gas turbine technology enables CES to design gas turbines that work with steam/CO2 drive gas.

 

Because drive gas from the gas generator exits at optimal pressure and temperature, CES oxy-fuel turbines have no need for the air compressors and combustor cans that are essential components of conventional turbines. By removing these components, CES' technology reduces parasitic load and allows approximately three times more power to be extracted from the conventional turbine section now making the main element of these oxy-fuel expander turbines. 

 

When designing the OFJ-79 and the OFT-900, CES concentrated on re-purposing existing turbines that are based upon proven, decade-old technology, such as the aero-derivative GE J-79 and the industrial Westinghouse W-251 (Siemens SGT-900). Always striving to push boundaries, CES plans to exploit the advantages of oxy-fuel turbines further by basing future designs on more progressive, current technology status quo. Additionally, instead of basing future designs on existing turbines, it is intended to working with our turbine OEM partners to developing expanders based on the capabilities of the CES gas generators. With steam generated at pressures easily exceeding 2,000 psi and more and temperatures reaching up to 3,200 F, leaps in turbine expander efficiencies can be expected.

 

 

 

 

 

 

 

 

 

 

 

 

Oxyfuel Combustion

Oxy-fuel combustion has been the propellant system of choice since the early days of rocket science. Defined as a combustion process, in which fuel is mixed with an oxidizer such as pure oxygen, oxy-fuel combustion has been effectively used in solid, liquid, and gaseous combustion systems.

 

At the core of CES' technology is an oxy-fuel combustion system adapted from the same principles of rocket propulsion technology that power the Space Shuttle. The CES combustor burns clean gaseous and/or liquid fossil fuel with gaseous oxygen at near-stoichiometric conditions in the presence of recycled or even untreated produced water. It can burn a wide variety of fuels, including natural gas, associated or produced gas, syngas, refinery residues, landfill gas, bio-digester gas, and renewable fuels such as glycerin from bio-diesel production facilities. Even emulsified bitumen and micronized petcoke have been proven to be useable fuels, although they are not at commercial readiness yet.

 

CO2 and steam are the primary products of the oxy-fuel combustion process. CES technology is able to recover 100 percent of CO2 produced, ensuring that no pollutants are released into the air. The ready production and recovery of CO2 is a game-changer for the enhanced oil recovery (EOR) industry.

 

 

 

 

 

 

 

 



Kimberlina Power Plant

Clean Energy Systems' Kimberlina Power Plant (KPP) is the world largest oxyfuel combustion facility. This former 5MWe biomass power plant is now host to most of CES' testing and demonstration equipment. It is laid out primarily for R&D and sub-commercial operations and today is home to

  •  the CES 4" Gas Generator
  •  the G2S2 SAGD Gas Generator and Steam Separator commercial scale test bed
  •  the CES 12" Gas Generator
  •  the CES OFJ-79 30MWe expander turbine

 • a fully operational 100% carbon-capture ready, 1,500 Mscfd CO2/5MWe steam turbine cycle for continuous operations
  •  a full-scale solar and geo-thermal steam booster test-bed, and much more...

 

The 40-acre site provides ample space for both future R&D programs and continuous full scale commercial operations. It is ideally situated - wedged in between heavy and light oil fields thirsty for steam and CO2, in the middle of the water-deprived nut and fruit orchards of of the Central Valley, and sitting on top of a WESTCARB-identified CO2 storage field. The site is host to Areva Solar's Kimberlina Solar-Thermal demonstration facility.

Placerita Power Plant

Clean Energy Systems' Placerita Power Plant (PPP), a former 120MWe combined heat and power plant (CHP), sits tucked away in the hills of the Placerita oil field, close to Santa Clarita in the north of LA county. CES acquired the facility in early 2011 after it had been idle since 2008.

 

PPP allows CES to deploy their equipment in a wide variety of configuration while building on a wealth of existing infrastructure, such as a 120MWe power interconnect and a gas pipeline interconnect.

 

CES further acquired some of the land surrounding PPP, including the associated mineral rights, to provide for an ideal test site for power a CES CHP concept producing steam for thermal oil recovery, while selling zero-emission power into the southern Californian power grid.
