On November 30, 2016, the European Union’s Commissioner for Climate Actions & Energy, Miguel Arias Cañete, announced the details of a major clean energy package. Front and center in the plan are the EU’s new target of an at least a 30% increase in energy efficiency compared with 1990 levels. That is up from a pre-existing target of 27%.
The strategy is intended to help the EU to become less dependent on energy imports, create jobs and reduce emissions that contribute to climate change.
“Europe is on the brink of a clean energy revolution,” Miguel Arias Cañete told a press conference in Brussels. “And, just as we did in Paris, we can only get this right if we work together.”
The bloc’s vice president for energy union, Maroš Sefcovic added: “This is really something of a transformational nature that we are proposing – perhaps the biggest since the central power systems were built in Europe.”
The commission says that the new package’s benefits include a €177 billion ($252 billion Canadian) mobilization of public and private investment per year in the next decade, which is expected to create as many as 900,000 new green tech jobs and spur a 1% increase in GDP.
Our President and CEO, William Crossland, and a few of our team from Thermal Energy International are participating in the Canadian Energy Efficiency Alliance’s 2016 Day on the Hill: Meetings that Matter, in Ottawa, Ontario. Thermal Energy has also sponsored the event.
The event is an opportunity for Mr. Crossland and our team to meet with government officials and national decision-makers to discuss our energy efficiency solutions and how they help address climate change.
Key decision makers attending include:
The combination of our FLU-ACE® heat recovery system and GEM™ steam traps installed at one of the Wrightington, Wigan and Leigh NHS Foundation Trust’s hospitals received the Highly Commended designation for improving sustainability and reducing energy at the 2016 Building Better Healthcare Awards.
The FLU-ACE heat recovery system (ordered in January of 2015) works by drawing off the waste gasses from the hospital’s boilers instead of letting it escape up the chimney. These gasses are then put through a unique heat recovery technology that condenses the gasses, releasing all the available energy within them. This means that instead of exhausting to atmosphere at 200°C, which creates a visible “plume” of wasted energy at the boiler house, the hospital can use all the energy and exhaust at 31°C instead, making it 99% efficient.
This energy is used on site to heat 20m3 of water for heating, and 6m3 of water for domestic hot water, every hour of the year. This in turn means that the boilers have to do less to keep the same amount of hot water flowing around the hospital, so the amount of natural gas used drops.
We had previously installed our GEM steam traps on site. Unlike a conventional mechanical trap, our venturi orifice GEM steam traps enable continuous condensate discharge. Our traps are specifically sized to the application. Therefore the live steam loss through our GEM steam traps is significantly lower than the loss through a conventional mechanical trap. By switching to the GEM steam traps on all of the hospital’s distribution lines and processes, the same amount of hot water is produced whilst reducing steam consumption by 11%. All the new GEM steam traps are covered by a 10-year no-fail guarantee.
The Trust was able to fund these projects with Salix funding, where the payments to Salix were less than the savings, meaning the hospital would be cash positive all the way through.
The projects were set to reduce the Trust-wide CO2 emissions by 968 tonnes per annum, which is a remarkable 7% reduction on 2010/2011 levels, and also put the Trust firmly on track to over achieve the savings stipulated by the government.
Combined, the projects were expected to provide the hospital with annual savings of approximately £170,115, mainly as a result of a reduction in fuel usage, steam savings, and maintenance savings. However, the projects achieved the financial and CO2 savings in the first eight months of the year, meaning the projects have over-performed.
Based on the success of these projects, the Trust ordered an extension to the original heat recovery system (which will double its effectiveness on site and add redundancy to all of the plant rooms, making the patient environment more stable and reliable), as well as two heat recovery systems and one GEM system at the Trust’s other two hospitals.
Thermal Energy International helps hospitals save money by reducing their fuel bills while also lowering their greenhouse gas emissions. Our proven solutions can increase the efficiency of your heating and steam system to as much as 95% with typical project paybacks (for our combined technologies) within three to five years. >> View case studies

Governments and businesses around the world are taking unprecedented action with respect to climate change. While renewable power sources and phasing out harmful hydrofluorocarbon gasses will likely play a big role in the world's fight against global warming, improving energy efficiency is perhaps the most cost-effective way to address the challenges of energy cost, energy security and global climate change. To help get the message out there, this will be the first in a series of Climate 101 blog posts and accompanying materials that discuss how improving industrial energy efficiency can make a huge difference - not only in reducing carbon emissions, but also in making businesses more profitable and competitive.
"Energy efficiency is the one energy resource that all countries possess in abundance.” - Dr. Fatih Birol, executive director of the IEA
The industrial sector accounts for about one third of the total energy consumed and one-third of fossil fuel related greenhouse gas emissions in the United States. In addition to moral obligations to our planet, our children and future generations, there is clearly an ongoing need for companies to continue with their energy efficiency efforts, even with the prevailing low energy prices we are seeing today. Businesses cannot take it for granted that energy prices will continue to stay at the current low level over the medium to long term. While many industrial companies are taking some positive action, substantial energy efficiency opportunities for manufacturers still remain.

Close to 200 nations agreed to a legally binding deal over the weekend to target and reduce hydrofluorocarbon (HFC) gases. Factory-made HFC gases are used in air conditioning units and fridges and can be 10,000 times more powerful than carbon dioxide as greenhouse gases. HFCs replaced the previous use of CFC gases, which were even more damaging to the environment. HCFs are the fastest-growing greenhouse gases in the US, China, India, and the EU. If left unchecked, emissions of HFCs could grow to nearly 20% of CO2 by 2050 and 45% if CO2 emissions are limited in line with present international goals.
Under the agreement, developed nations, including the United States and much of Europe, commit to reducing their use of HFC gases incrementally, commencing with a 10% cut by 2019 that will increase to 85% by 2036.
More than 100 developing countries, including China, the world’s top carbon dioxide emitter, will begin taking action in 2024, siting that they needed more time because they have fast-expanding middle classes and hot climates, and fear of damaging their growing industries.
It is estimated that between 2020 and 2050, 70 billion tonnes of CO2 equivalent, comparable to the emissions of nearly 500 million cars, will be prevented from entering the atmosphere thanks to a progressive reduction of HFCs.
The signing of this agreement is news that is dear to us at Thermal Energy International. We help our industrial and institutional clients reduce their environmental and carbon foot print while also saving them money through reduced fuel use.

Improving energy efficiency is one of the best ways for businesses and institutions to both lower their energy costs and reduce harmful greenhouse gas emissions. Improving energy efficiency can also make businesses more competitive and help institutions such as hospitals and universities reallocate funds to staffing, programs and needed equipment. Energy efficiency is a win-win situation.
So it should come as no surprise that planned investment in energy efficiency technologies stands at an all-time high according to the 2016 Energy Efficiency Indicator (EEI) survey, conducted by U.S.-based energy efficiency and automotive firm Johnson Controls. Of the 1,200 facility and energy management executives surveyed, 72% said they expect their company to invest more in energy efficiency and renewables in the next year. This is a steep rise in comparison to a similar survey in 2013, when only 42% of companies planned to increase their investments.
Improving industrial energy efficiency is one of the most economically effective means of combatting climate change. According to scenarios from the International Energy Agency, more than 40% of the greenhouse gas emission reductions required to limit increases average global temperature within two degrees Celsius by the end of the century will have to come from increases in energy efficiency.
If your plant, hospital or campus uses a significant amount of electricity and fuel is used for heat, you may want to take a look at cogeneration.
Cogeneration is an integrated energy system that provides electricity and heat, usually in the form of hot water or steam. While not really an energy source itself, cogeneration (also known as combined heat and power, or CHP for short), squeezes more usable energy out of each unit of fuel most everywhere it is applied.
Electricity generation based on fossil fuels is rather inefficient. Heat is an inevitable by-product of any power produced by gas or steam turbines. With cogeneration, the waste heat from electricity generation is recovered and used for applications such as space heating and cooling, water heating, and industrial process heat. By converting heat to useful steam or hot water, a typical cogeneration unit can produce combustion efficiencies of as high as 75% to 80%, compared to about 40% for a combined-cycle gas turbine plant at full load.
Combining a typical cogeneration product with Thermal Energy’s proprietary FLU-ACE® heat recovery technology can push efficiency up to as high as 93%.
Manufacturing operations and other industrial process plants, hospitals, universities and other institutions with a year-round need for both electrical power and steam are candidates for cogeneration. Other candidates are commercial buildings, multi-unit residential buildings and district energy systems. In areas where the relative cost of purchased electricity versus a readily available fossil fuel like natural gas is favorable, cogeneration can satisfy much of a facility’s electricity and heating needs at a substantially lower cost than traditional means. In addition, with absorption chilling, cooling loads can also be met with waste heat from on-site power generation (this is known as trigeneration).
Cogeneration remains among the most efficient ways to convert fossil fuels and biomass into useful energy and can make a significant contribution to meeting energy efficiency improvement targets. 
Appropriate sizing and selection of equipment is the most critical factor to the success of any cogeneration project. If incorrect, the plant will not meet the expected output or return. Identifying an appropriate and available location to place the equipment early is crucial as this can significantly impact on the implementation costs if no adequate space is freely available.
For many industrial and institutional operations, cogeneration is an energy solution that can save money, improve energy reliability and security, while reducing the facility’s “carbon footprint.” An assessment and/or study by Thermal Energy’s qualified engineering team can help you determine whether cogeneration should play a part in the energy solution for your facility.

Hospitals tend to consume more energy per square foot than many other commercial building types, including offices and retail stores, or even educational buildings. Hospitals are open 24 hours a day; occupied by hundreds or thousands of employees, patients, and visitors. They tend to have sophisticated heating, ventilation, and air conditioning systems to control temperatures and air flow. And, many energy-intensive activities occur in hospitals: laundry, medical and lab equipment use, sterilization, food service, refrigeration, and computer and server use. It’s not surprising then that hospitals make great candidates for our proven energy efficiency products.
... hospitals are among the nation's most complex and energy intensive facilities and 80% of energy costs are from heating alone."
Thermal Energy’s FLU-ACE heat recovery technology effectively recovers the waste heat from a hospital's boiler operations and uses it to preheat a heat sink – this could be water for your space heating, domestic hot water, boiler feed water, or outside air heating. By replacing the existing load with our recovered energy, many hospitals have been able to prove savings of 20% on their fuel bills.
Just how much energy hospitals use (and waste) and how it can be reduced was the topic of a recent article in Built Environment – a U.K. publication dedicated to showcasing the region's construction projects, products and technical innovations.

As much as 60% to 80% of a typical paper mill’s energy can be used for drying of the product. Our FLU-ACE heat recovery technology can recover as much as 90% of the heat normally lost through dryer section / hood exhausts in the form of water at 50°C to 70°C. This is possible using the FLU-ACE’s unique direct contact (gas/liquid) packed-tower design, enabling optimal recovery of both sensible and latent heat, in widely varying operating conditions. Here is a case study that looks at one of our FLU-ACE heat recovery systems installed at one of our customers' pulp mills.
Thermal Energy implemented a FLU-ACE Condensing Heat Recovery System on the smelt dissolving tank vent at the pulp mill. The system was designed to recover an average of 12 MMBtu/h of waste heat energy that would otherwise be exhausted to the atmosphere. The waste heat from the exhaust is used to preheat boiler make-up water, reducing steam use in the deaerator. This resulted in elimination of the mill’s consumption of fuel oil and a commensurate reduction in greenhouse gas and other emissions equivalent to removing 2,085 cars from the road.
The project was implemented on a turn-key basis and was completed on budget and on schedule. Under this program, the equipment is owned and operated by Thermal Energy over a given term whereby the recovered energy is metered and charged on a $/MMBtu rate basis that provides a continuous energy cost saving to the user. This provides an immediate cost savings benefit to the user without the requirement to deploy any internal capital - positive cash flow from day one!
In recent years, steam systems have increasingly been branded as inefficient and a problem to maintain. Some sites are decommissioning steam and switching to hot water or other means of energy transfer, expecting it to be more efficient. This is a real pity as steam is still the quickest and most effective way to transport heat energy around a plant. In fact the problem isn’t that steam systems are not effective, it is that most people have no idea that they can optimize their existing system by recovering any wasted energy.
There is an effective way to permanently increase the efficiency of such systems to over 80%. On average only 55% of the fuel Input to a steam system is used as useful heat output. Of the 45% wasted energy the biggest losses are the 15-25% that goes up the stack as exhaust gasses and 10% that is lost through leaking steam straps. Both these losses can be easily recovered by implementing two simple projects bringing the efficiency of your steam system to at least 83%.
Technology 1 – Direct Contact Condensing Economizer
We all know about traditional boiler economizers. They fit on to the back of your boiler and can usually collect about 2-4% of the wasted energy. This system however has application limitations and can only recover the sensible heat from the waste gas. A Direct Contact Condensing heat recovery system, such as FLU-ACE, can recover the full 18% stack losses providing fantastic returns. The system can reduce the boiler exhaust gas temperature below the exhaust dew point as far as 25°C. Cooling beyond the dew point releases all the latent energy in the exhaust by condensing all the moisture inside a separate stack. For a natural gas boiler, this latent energy will be around 18% of energy in the fuel. By the time boiler and distribution losses have been accounted for, they can typically save 20% of the fuel bill.
FLU-ACE can recover the waste heat from the exhausts on boilers, CHP plants, dryers and other industrial heat sources. The recovered energy can be used for example, to pre-heat makeup water, heat Domestic Hot Water (DHW), or be used for heating systems etc. In addition, this also reduces greenhouse gases and helps work towards energy reduction targets. The control panels on the heat recovery units can also contain data loggers that continually record the energy being recovered and provide fault warnings if any issues arise. The system is very low maintenance, stand alone and payback on a typical project is usually 2-3 years and the units have a predicted lifespan of 20-30 years.
Technology 2 – Venturi Orifice Steam Traps
On average, 10% of mechanical steam traps fail annually. These steam traps can either fail open or closed. When they fail open they leak live steam which is inefficient, wasteful and can pressurise condensate recovery lines. When they fail closed, the condensate can back up causing waterhammer and if not detected quickly, can be catastrophic causing pipework to erode, and at times explode.
It is the moving parts in mechanical traps that cause them to fail. Low maintenance steam traps like our venturi orifice GEM traps can provide an ultimate permanent solution. These steam traps do not contain any moving parts and therefore remove the possibility of a trap failing. When correctly implemented, they are sized to ensure that no live steam can ever pass through. This makes them energy saving and maintence free.
Venturi steam traps functions on a principal of flash steam. Following the orifice there is a cleverly configured staged throat that is individually sized for the application to accommodate its varying condensate loads. The staged throat is designed to create a variable back pressure at the orifice as the load changes self-regulating their capacity across a range suitable for the vast majority of industrial applications.
Combining these two proven technologies can recover 28% of the energy wasted. Making this more cost effective and more efficient then decommission or changing your heat source. Not only is this more efficient but it also involves less time hassle and money as there is no need to redesign and implement an entirely new system.
