Carbon-Free Energy from Industrial Exhaust

Pollution to Clean Power

by | Oct 7, 2022 | CASE STUDIES

The exhaust from many industrial processes is clean and very hot (850 -1,000°C), yet in many cases it is simply vented into the atmosphere…in other words, it’s wasted. 

OUR SOLUTION

247Solar’s Heat2Power™ Turbine converts waste heat to electricity without emissions 

  • Electricity can be used or sold 
  • Turbine’s 650exhaust can be used to reduce fuel costs for industrial process heat 
  • Uses atmospheric-pressure clean air, minimum 850 
  • Ideal for use with RTOs (Regenerative Thermal Oxidizers) that clean dirty industrial exhausts
EXAMPLE USE CASE 

A landfill in Australia uses a municipal solid waste gasifier that converts a wide variety of solid waste to useful products. These reduce landfill volume and resulting methane emissions. The gasifier’s dirty exhaust is connected to an RTO. In turn, the oxidizer’s clean hot exhaust drives 247Solar’s Heat2Power Turbine to produce electricity and also to supply heat to the gasification process. 

Twenty percent (20%) of the turbine’s output eliminates the gasifier’s power costs. The remaining 80% is available for profitable sale. The turbine’s waste heat (up to 650oC) can be used by different gasifiers in different ways. 

 BENEFITS 

  • Turbine’s electricity reduces operating expenses, creates new revenue stream 
  • Turbine’s heat further reduces operating costs 
  • Gasifiers reduce solid waste streams to municipal landfills 
  • Smaller landfills mean less climate-warming methane 
  • Zero carbon power and heat help mitigate climate change
