What is Waste Heat?
Waste heat is an untapped, sustainable resource that goes largely underutilized today. Simply, it is the excess heat produced most commonly in power generation and industrial processes. According to the second law of thermodynamics, heat must be produced when converting a temperature difference into mechanical energy.
What does this mean? This means waste heat is inevitable. In fact, almost all industrial processes and heat engines see over 50% of the input energy lost as waste heat. This heat is often vented to the atmosphere or dumped into bodies of water. During a time where global demand for energy is exploding, this is not only an immense waste of resources but is also a significant contributor to global warming.
Fun Fact – If harnessed, the waste heat from industrial processes in the United States can provide 10 gigawatts of emission-free electricity, enough to power over 10 million American homes and save U.S. industries over $3,000,000,000 annually. According to the U.S. Department of Energy, capturing this heat could generate as many as 160,000 jobs. Plus, since most power generation and industrial processes operate 24 hours a day, 7 days a week – the integration of heat recovery technology can provide a reliable baseload power supply. Waste heat to power systems allow companies to increase efficiency while generating their own emission-free electricity – which can be used to reduce operating costs or sold back to the grid to act as an additional revenue stream.
Another study shows that the United Kingdom could prevent over 10 million tons of carbon dioxide emissions annually by using the waste heat from their largest power stations to warm homes and infrastructure. The reduction in emissions is equivalent to taking 2,000,000 cars off the road for an entire year!
Next Generation Waste Heat Recovery
Did you know that over 90% of waste heat in the United States is at too low a temperature for traditional turbine systems to economically capture? With recent advancements in ORC technology, small-scale applications can now reap the same benefits previously only seen by mulit-megawatt powerhouses. The ability to capture this lower temperature heat opens opportunities across all industries.
// Reduced engine de-rate, which leads to more up time and revenue.
// Reduced parasitic load, which increases effective horsepower and energy efficiency.
// Reduced energy costs, from generating your own clean electricity with no additional fuel combustion.
// Reduced emissions, from utilizing your waste heat and becoming more self-sufficient.
Fun Fact – Air conditioners and radiators account for approximately 10% of global energy consumption and demand is predicted to triple by 2050. In this aspect, a high efficiency cooler such as the ElectraTherm Active Cooler provides an excellent solution for industries making use of commercial radiators to expel heat greater than 60°C. The net-zero power cooler utilizes the latest waste heat recovery technology to fulfill all your system’s cooling needs while generating profitable power.
That is only the beginning. With ElectraTherm, it is simpler than you think.
