6 Industrial Facilities have many waste stream Water, Waste, and stack emissions

7 Heat goes up the stack There are relatively clean exhausts and relatively dirty exhausts Heat is Energy already created like sunlight

9 Classic steam engine! Takes heat- boils a liquid- turns a turbine

11 1 Heat water 2 Expand water to a gas 3 The expanding gas turns a turbine

12 4 Turbine generates electricity 5 Escaping steam goes up the stack Think Locomotive Turbine like a Hydro Dam

13 don t need to stoke a boiler Most industrial facilities just vent their stack heat Some use it to heat steam for building heating

14 Create electricity Heat water or some other liquid- send it through a turbine to create electricity Some energy intensive industries would benefit from the low cost power

15 A carbon based chemical- propane, refrigerant, etc Key is to have the fluid expand and contract within a narrow operating temperature band This increases the cycle time and increases the energy output while keeping the volume of fluid at a minimum

16 Uses high temperature waste heat Diverted from the stack Through an ORC unit Uses an Organic fluid rather than water Turns a turbine mini powerplant

17 An organic Rankine cycle (ORC) is a thermodynamic cycle that uses a carbon based working fluid to convert energy flowing from a higher temperature heat source to a lower temperature heat sink into useful power. The cycle was first documented by Scottish engineer William Rankine in the 1850s and the cycle begins with the working fluid in a low pressure liquid state

19 Organic Rankine Development Used extensively for Geothermal applications High potential for waste heat recovery Smaller unit sizes possible Collaborative development with our industry partners Barber Nichols UMC

20 The working fluid is then passes through a pump which elevates the pressure and sends it to a vaporizer (higher temperature heat source) where it is converted from a liquid into a high pressure vapor. The high pressure vapor is then expanded across a powerproducing turbine before being converted back into a low pressure liquid in a condenser (low temperature heat sink).

21 The steam Rankine cycle is well developed and utilized worldwide and it differs from the organic Rankine cycle because the working fluid is water rather than a carbon based compound. And in addition to the basic Rankine cycle, more sophisticated variants have been developed including superheated, recuperated, and supercritical cycles which increase efficiency and therefore power output

22 Free energy source( heat) Uses an organic fluid that is both smaller in volume and sealed under much less pressure Has a more narrow phase change range targeted to the heat range of the stack important so that the gas changes back to liquid rapidly for recycling through the system Sealed system no waste, the organic material lasts forever( essentially)

23 Hot air heads for the industrial stack Re-routed through the ORC unit Passes through the heat exchanger Continues on and exits stack Heat exchanger expands organic fluid Pressure turns the turbine

24 Generates electricity-passed on to grid Organic fluid condenses and recycles Continuous process Very little maintenance ( sealed bearings) Free electricity produced ( minus operational expenses)

25 Good Efficiency at Low Temperature Allows use of standard materials Increases range of operation Provides heat rejection options Allows fuel choice optionality Waste Heat/Geothermal Medium Power Density = Small Systems Lower costs and maintenance Factory construction Simplified shipping Simplified financing Reduced time to revenue Ability to scale capacity No need for water

26 Physical Plant ~9 feet by 10 feet by 32 feet All Off the Self Components except for TurboMachinery S-ORC PowerCub e 2 MWe Diesel Generator

27 Available to every industrial facility that has a emissions stack The state of WA has already ruled that these projects are I-937 compliant-( credits against greenhouse gas production) Free energy(minus low maintenance costs) after the initial payback period

28 U.S.Senate energy bill Bipartisan support Murkowski/ Cantwell. The legislation is important to the WHP industry because it adds WHP to the federal definition of renewables

29 Benefits Low Environmental Impact Cuts greenhouse gas emissions saving over 2,300 tons of CO2 per year. Reduces thermal and air pollution. Increases energy usage efficiency. Compact footprint. Cost Effective Improves energy conservation. Eligible for Carbon or Renewable Energy Credits, where available. Minimizes capital equipment expenditures. Automated personnel operation. Reliable Closed loop design. Minimal maintenance. High cycle efficiency. Long plant operational life. Fully Integrated Power Up to 400 kw of electricity. Interfaces with industry standard systems for waste heat recovery. Grid independent. Scalable.

30 Ball Park based on my experience: Depends on: Cost of local electricity Cost of site construction Any rebates from utility Systems in operation internationally where electricity is more expensive

31 Clean: Conserving energy through a clean, carbon-free cycle qualifies for renewable energy standards in many states and lowers energy costs. Compact: The PowerCube ISX440 utilizes an Organic Rankine Cycle to deliver high thermal to electric conversion efficiency in a compact footprint. Cost Effective: Operates at lower pressures and does not require water chemistry maintenance, which eliminates the need for full time plant operators.
