What is "Trigeneration"?

Trigeneration is the simultaneous production of three forms of energy - typically, Cooling, Heating and Power - from only one fuel input. Put another way, our trigeneration power plants produce three different types of energy for the price of one.  

Trigeneration energy systems can reach overall system efficiencies of 86% to 93%.  Typical "central" power plants, that do not need the heat generated from the combustion and power generation process, are only about 33% efficient.

Trigeneration Power Plants' Have the Highest System Efficiencies and are 
About 300 % More Efficient than Typical Central Power Plants

Trigeneration plants are installed at locations that can benefit from all three forms of energy.  These types of installations that install trigeneration energy systems are called "onsite power generation" also referred to as "decentralized energy."   

One of our company's principal's first experience with the design and development of a trigeneration power plant was the trigeneration power plant installation at Rice University in 1987 where our trigeneration development team started out by conducting a "cogeneration" feasibility study.  The EPC contractor that Rice University selected installed the trigeneration power which included a 4.0 MW Ruston gas turbine power plant, along with waste heat recovery boilers and Absorption Chillers.  A "waste heat recovery boiler" captures the heat from the exhaust of the gas turbine.  From there, the recovered energy was converted to chilled water - originally from (3) Hitachi Absorption Chillers - 2 were rated at 1,000 tons each, and the third Hitachi Absorption Chiller was rated at 1,500 tons. The Hitachi Absorption Chillers were replaced shortly after their installation by the EPC company.  The first trigeneration plant at Rice University was so successful, they added a second 5.0 MW trigeneration plant so today, Rice University is now generating about 9.0 MW of electricity, and also producing the cooling and heating the university needs from the trigeneration plant and circulating the trigeneration energy around its campus.

As you can see, there is No Competition for Trigeneration!

Our trigeneration power plants are the ideal onsite power and energy solution for customers that include:  Data Centers, Hospitals, Universities, Airports, Central Plants, Colleges & Universities, Dairies, Server Farms, District Heating & Cooling Plants, Food Processing Plants, Golf/Country Clubs, Government Buildings, Grocery Stores, Hotels, Manufacturing Plants, Nursing Homes, Office Buildings / Campuses, Radio Stations, Refrigerated Warehouses, Resorts, Restaurants, Schools, Server Farms, Shopping Centers, Supermarkets, Television Stations, Theatres and Military Bases.

At about 86% to 93% net system efficiency, our trigeneration power plants are about 300% more efficient at providing energy than your current electric utility. That's because the typical electric utility's power plants are only about 33% efficient - they waste 2/3 of the fuel in generating electricity in the enormous amount of waste heat energy that they exhaust through their smokestacks.

Trigeneration is defined as the simultaneous production of three energies: Cooling, Heating and Power.  Our trigeneration energy systems use the same amount of fuel in producing three energies that would normally only produce just one type of energy. This means our customers that have our trigeneration power plants have significantly lower energy expenses, and a lower carbon footprint.

What is the "Unified Smart Grid"?

The Unified Smart Grid is the name used for the future transmission power lines that would carry green electricity from the many solar power plants and solar power parks and wind farms that generate the power, typically in remote areas, to the "load centers" or major cities that would use the green power. 

Quite simply, our country's out-dated and inefficient National Electric Grid, lacks the ability to carry all the new green electricity being planned from hundreds of new solar power parks and wind power generation facilities.

The Unified Smart Grid will be a national interconnected network relying on a high capacity backbone of electric power transmission lines linking all the nation's local electrical networks that have been upgraded to smart grids. Europe's analogous project is sometimes referred to as the SuperSmart Grid, a term that also appears in the literature describing the Unified Smart Grid. 

Cost estimates to rebuild the nation's electric grid as a Unified Smart Grid have ranged from $350 billion to $450 billion.

Support for the unified smart grid came with passage of the Energy Independence and Security Act of 2007.   Title 13 of this Act invested $100 million in funding for the years 2008 – 2012 and establishes a matching program to states, utilities and consumers to build unified smart grid capabilities.  It also creates a Grid Modernization Commission to assess the benefits of demand response and automated demand response and recommended a set of system protocols and standards to be led by the National Institute of Standards and Technology which would coordinate the development of smart grid standards.  FERC would then promulgate these standards and protocols for the unified smart grid through its official rulemaking capabilities.

The Unified Smart Grid received further support with the passage of the American Recovery and Reinvestment Act of 2009 that set aside $11 billion for the creation of a smart grid.

Building a Unified Smart Grid would help jump-start the renewable energy investments in solar power parks.  Thousands of megawatts of new solar power parks (both Concentrating Solar Power plants and Photovoltaic Power Plants) are being planned. Most are  located in the desert Southwest due to the solar energy resource. A Unified Smart Grid is needed to move the large amount of power, which is fairly concentrated, to the rest of the nation.  Without the new Unified Smart Grid, it would be impossible to distribute the green power to the nation. 

The new Unified Smart Grid is significantly more efficient than the present, nearly 100 year old technology that makes up our nation's present transmission and distribution network of how we get the power from central power plants to customers and major load centers.

Much of the new Unified Smart Grid will be comprised of "High Voltage Direct Current" transmission lines which is significantly more efficient than the present high voltage alternating current transmission lines.  

The new Unified Smart Grid will provide economic development, thousands of new jobs, and significantly reduce greenhouse gas emissions.

What would the new Unified Smart Grid look like?

Waste Heat Recovery in Cogeneration and 
Trigeneration power and energy systems

In most cogeneration and trigeneration power and energy systems, the exhaust gas from the electric generation equipment is ducted to a heat exchanger to recover the thermal energy in the gas. These heat exchangers are air-to-water heat exchangers, where the exhaust gas flows over some form of tube and fin heat exchange surface and the heat from the exhaust gas is transferred to make hot water or steam. The hot water or steam is then used to provide hot water or steam heating and/or to operate thermally activated equipment, such as an absorption chiller for cooling or a desiccant dehumidifer for dehumidification.

Many of the waste heat recovery technologies used in building co/trigeneration systems require hot water, some at moderate pressures of 15 to 150 psig. In the cases where additional steam or pressurized hot water is needed, it may be necessary to provide supplemental heat to the exhaust gas with a duct burner.

In some applications air-to-air heat exchangers can be used. In other instances, if the emissions from the generation equipment are low enough, such as is with many of the microturbine technologies, the hot exhaust gases can be mixed with make-up air and vented directly into the heating system for building heating.

In the majority of installations, a flapper damper or "diverter" is employed to vary flow across the heat transfer surfaces of the heat exchanger to maintain a specific design temperature of the hot water or steam generation rate.

Typical Waste Heat Recovery Installation

In some co/trigeneration designs, the exhaust gases can be used to activate a thermal wheel or a desiccant dehumidifier. Thermal wheels use the exhaust gas to heat a wheel with a medium that absorbs the heat and then transfers the heat when the wheel is rotated into the incoming airflow.

A professional engineer should be involved in designing and sizing of the waste heat recovery section. For a proper and economical operation, the design of the heat recovery section involves consideration of many related factors, such as the thermal capacity of the exhaust gases, the exhaust flow rate, the sizing and type of heat exchanger, and the desired parameters over a various range of operating conditions of the co/trigeneration system — all of which need to be considered for proper and economical operation.

How we make and distribute electricity is changing! 

The electric power generation, transmission and distribution system (the electric "grid") is changing and evolving from the electric grid of the 19th and 20th centuries, which was inefficient, highly-polluting, very expensive and “dumb.”  

The "old" way of generating and distributing energy resembles this slide:

According to Monty Goodell, Founder and Chairman of the Renewable Energy Institute, "our increased dependence and reliance on foreign energy supplies represents a Clear and Present Danger to our national security, our economy, and the lives and livelihood of every American. Energy - including the energy we use from imported fossil fuels, is the very "lifeblood" of the American economy as it is for every industrialized country.  An economy dies without it's lifeblood of energy. This Clear and Present Danger we face is far more serious than the problems related to greenhouse gas emissions.  And while greenhouse gas emissions are very serious issue, in the long-term, pales in comparison to America's vital national security interests and America's economic stability in the short term.  For this reason alone, America needs to transition away from its addiction to foreign energy supplies. And America's abundant renewable energy resources such as the energy we receive from the sun, and renewable energy technologies such as concentrated solar power (CSP) plants - can supply 100% of America's power requirements with a concentrating solar power plant measuring 75 miles by 75 miles, located in the Southwest U.S.  By generating America's power from concentrating solar power plants, America resolves its' short-term Clear and Present Danger as it relates to importing its energy from foreign countries, and the long-term problems relating to greenhouse gas emissions."

Continuing, Mr. Goodell states that "too many Americans have forgotten what happened to us in 1973, when the Arabs and OPEC brought the United States economy to a screeching halt during the OPEC Oil Embargo.  This happened because they (mainly the country of Saudi Arabia) disagreed with our foreign policy and is the reason why they "turned off the tap" of our need for their oil supplies. When Saudi Arabia and OPEC stopped the vital flow of oil to our country in 1973, they caused an "oil shock" that severely and negatively impacted our economy. 

Mr. Goodell's question for us to ponder is, "do these countries who sell us 60% of our daily energy requirements, like us and our foreign policy, or might they leverage our addiction to their fossil fuels, and turn off the tap to make us adjust or revise our foreign policy??  Like any addict, America's foreign policy may be held hostage to its addiction, and in this case, our addiction to foreign oil, may over-ride our national interests."

Have American's forgotten the gas shortages and long lines at 
their gas stations to get gas during the Arab Oil Embargo of 1973? 

"Apparently so."  Mr. Goodell states that "in 1973, America was 'addicted' and 'over the barrel' of foreign oil to the amount of 40%.  Forty percent of our energy 'needs' in 1973 came from countries - many of which didn't like us then, and I'm afraid, many of them still don't.  The difference between 1973 and today - is that today we receive 50% MORE foreign oil now than we did in 1973.  And now we know about the problems relating to greenhouse gas emissions that we didn't know then.  America needs to change course, and change course now, in terms of its' energy supplies and how we keep America's economy strong, without the threat of being held hostage to a middle-east tyrant or regime, that could once again, turn on us, and turn off our supply of foreign oil." 

Remember ????

"Sadly, most Americans have forgotten the long lines of people waiting in their cars - lined up and waiting for gasoline at their nearby gas station, with lines that were many blocks long.  And, after waiting 4-5 hours, many even waiting overnight in many places, to finally take their turn to fill up their car with gasoline, only to find that the gas station had run out of gas."

"Let me Repeat.... That was 1973 when we imported 40% of our daily energy requirements in the form of crude oil from overseas, and from foreign countries - and many of these from countries that don't like us.

Today, over 35 years later, America has yet to learn the lesson.  We cannot continue our reliance on energy from foreign countries that supply us with 60% of the crude oil that our refineries use as a feedstock for producing gasoline and diesel fuel for our cars and trucks comes from overseas. 

America is "over the barrel" and it's not our barrel, but the barrels of oil that we are addicted by and owned by other countries.  Why have we not learned the lessons we needed to learn in 1973 when we were cut-off from the vital energy supplies we need? 

Countries like China, are growing rapidly, and have an insatiable need for crude oil. China, with their booming economy, is increasingly growing in its clout and control over international supplies of crude oil - whether they do this through their ability to buy as much oil as they need on a daily basis, or whether they simply but American drilling rigs, technology, and explore and produce oil and gas from their own fields. China, is buying large amounts of oil for their country, and causing upward pricing on declining supplies. What happens if Russia, with all of their oil and natural gas, along with China and Venezuela, with or without the help of OPEC, decided to NOT sell oil to us????

To be sure, greenhouse gas emissions are a problem, and to some, greenhouse gas emissions are also a Clear and Present Danger, but not to the extent that it presents an imminent Clear and Present Danger. 

America's reliance for 60% of our energy "needs" coming from foreign suppliers is un-acceptable.

The "driver" to get America to begin reducing and eliminating fossil fuel use should be our nation's national security and the welfare and safety of its citizens. And this can all begin with developing and investing in our own renewable energy resources and renewable energy technologies, let's start by putting solar on every rooftop that has a clear and unobstructed view of the Southern sky. See www.RooftopPV.com  or  www.DistributedPV.com  for more information.  Let's create incentives begin with adopting a national "Feed In Tariff" as Germany did in 1990. 

We simply do NOT have the luxury of time on our hands.  We need to end our dependence and reliance on foreign fossil fuels, especially from countries that don't like us! We need to rapidly begin expanding renewable energy resources and renewable energy technologies from our vast and abundant renewable energy resources, such as; solar, solar energy systems, solar cogeneration, solar trigeneration, "solar on every roof," along with; Biomass Gasification, B100 Biodiesel, Biomethane, E100 Ethanol (from cellulosic, agricultural waste, sugar cane, etc., and NOT from corn), Geothermal Power Plants, Natural Wastewater Treatment, Synthesis Gas, Waste To Energy, Waste To Fuel and Wind Power Generation where it makes economic and environmental sense."
