TransPacific Energy's (TPE) vision is to create innovative energy systems for a cleaner world
The Problem and the Solution:
Of the 500,000 smokestacks estimated in the United States, 47,500 of those stacks represent up 75% of untapped wasted heat above 500F heat that could produce at least 50,000 megawatts of power representing $100 billion in gross revenues. This is the “market” that is the target of TransPacific Energy's waste-heat powered electricity generator. TransPacific Energy’s power plant retrofits create electricity that can be used in industry or sold back to the utility company at regulated rates, with a high rate of return on the initial investment in the project.
Other markets such as geothermal and solar in the past required a minimum of 300ºF to cost effectively produce energy. With our technology we are able cost effectively to recover at temperatures down to 150ºF opening up old wells that have been capped and considered unachievable are now viable energy producing opportunities.
Our Difference: TransPacifc Energy has developed a patent pending heat recovery/energy conversion system that produces electricity from heat (such as; hot flue gases, solar, geothermal, gray water/hot fluids and warm ocean waters). The process uses an advanced Organic Rankine Cycle (ORC) with a patent pending, environmentally sound multiple refrigerant mixtures that tailored to maximize power production and can easily be adapted to broad range heat sources. It can be used where ammonia, propane, butane and other HCFCs and HFCs cannot be used. The process captures and converts heat directly from the source, without any heat transfer fluids (Binary Cycle), at temperatures as low as 80ºF up to 800ºF, a far greater range than any other ORC systems, which are limited to temperatures of around 200ºF to 350ºF or must use a binary system or secondary heat transfer to recover waste heat at higher temperatures costing efficiency and increasing costs. TransPacifc Energy’s solution eliminates the need for a binary heat exchange system since we recover directly and at much higher efficiencies.
Our Substantial Advantage: Our patent pending blend of multiple refrigerants enables us to engineer the highest efficiencies yielding greater power (from 6% to 30%). TransPacific Energy has a substantial advantage in other technologies, including the above-described Electric Power Generator, as well as Heat Pump and HVAC technology, thermal storage, and enhancing the performance of heat pumps and refrigeration systems.
