WASTE HEAT TO ENERGY
Rankine Cycle for high temperature processes (saturated / superheated steam)
Organic Rankine Cycle (ORC) for lower temperatures, using low boiling point working fluids to extract heat from industrial processes and primary mover turbine/engine exhaust, generating power for on-site use or to send back into the power grid.
WASTE HEAT SOURCES
Waste Disposal – landfills and water treatment plants
Agriculture – crop clippings, compost, animal waste, biodiesel, greenhouse heating
Lumber & Forestry – sawmills, lumber mills, biomass
Mining – air compressors, process hot water, generators, grinders, hydraulics
Oil and Gas – power generation, gas compression, refining, flare gas
Heavy Manufacturing – glass, cement, chemicals, metal foundries, kilns
Food & Beverage – food processing, waste by-products, industrial ovens
Refrigeration – wasted heat generated by refrigerant compressors
Data Servers – cooling towers and chillers using water, refrigerants, supercritical CO2
Transportation – transport trucks, ships, boats, trains and anything that uses an internal combustion engine where approximately 2/3 of the fuel energy is wasted as heat out the exhaust and radiator.
Nuclear Power – massive cooling towers
Nuclear Waste – Spent nuclear power fuel rods must cool 6-20 years in water baths before they can be buried. Vengeance Turbines can extend the useful life of nuclear fuel by using the low grade waste heat to generate more power.
Combined Heat & Power – Generating power and heat from the same fuel sources.
-Furnaces equipped with heat exchangers to create electric power
-CO-gen plants extracting exhausted heat from primary power generating equipment
Combined Cooling & Power – Enhancing industrial chillers with power generating technology. Chilling equipment dumps wasted heat into the environment through the air or using water sources. Increasing pressures from environmental regulators are being enforced to stop wasting precious water for cooling and to stop heating up rivers and waterways
GEOTHERMAL POWER GENERATION
Earth’s temperature rises with depth from the surface to the core. This gradual change in temperature is known as the geothermal gradient. In most parts of the world, the geothermal gradient is about 25° C per 1 kilometer of depth (1° F per 77 feet of depth).
By utilizing existing oil and gas drilling technologies, we can access this free heat for clean, abundant carbon-free power generation. Geothermal could be a vital part of the renewable energy solution because it provides continuous, stable baseline power. Wind and solar energy is not constant throughout the day. Geothermal Power can be produced 24/7. This means that geothermal can viably replace natural gas, coal and nuclear —the traditional baseline power sources.
Sources for heat extraction from underground would include abandoned oil and natural gas wells. Presently, there are over 400,000 abandoned inactive wells in North America.
SOLAR THERMAL POWER
Thermal heat energy from the sun can be harvested, stored and used on demand. Using Organic Rankine Cycle (ORC) can generate power in reduced sunlight conditions.
COMPRESSED AIR ENERGY STORAGE & POWER (CAESP)
CAESP takes the power delivered to the system (off-peak grid, wind, solar, geothermal, etc.) to run an air compressor, which pressurizes air and pushes it into natural storage areas such as underground salt caverns, rock caverns, depleted natural gas sites, expired natural gas/oil pipelines or large tanks. The heat generated during compression can also be stored for later use to increase system efficiency.
At a later time, when there is electricity demand, the pressurized air is released back to the surface and then used to spin our turbine, generating electricity.
Much higher efficiencies can be achieved if the heat of compression is stored and used to reheat the compressed air during turbine operation. This is referred to as isothermal or adiabatic CAESP and promises to compete with lithium-ion battery storage.
CAESP offers the potential for small-scale, on-site energy storage solutions as well as larger installations that can provide immense energy reserves for the grid.
Heating the compressed air is required by traditional turbines to prevent liquid droplet formation during air expansion. Our turbine is not affected by the liquid droplets in the expanding air during operation as it spins at a low RPM while delivering high torque.
Compressed-air vehicles (CAV) can be propelled by compressed air from storage tanks that is released and expanded inside our turbine.
Municipal Transit Busses would carry lightweight, high pressure carbon fiber tanks on their roofs that are filled with compressed air from renewable energy sources such as wind, solar and/or geothermal. Bus depots would collect energy from various clean sources to compress air in underground tanks. When the busses return to the bus depot from their routes, they would quickly refill their tanks. The bus depots themselves would be powered by renewable energy and use the stored compressed air in instances when wind and solar are not sufficient.
GAS PRESSURE LETDOWN
Natural gas pipeline pressure letdown stations are used to step down the pressure of natural gas at various stages of the natural gas distribution network. Commonly, a valve is used to drop the pressure resulting in wasted energy from the unused pressure. By replacing the pressure let down valve with our turbine, the high pressure spins the rotor and produces power while dropping the pressure to the desired setting. Our turbines are unaffected by variations of pressure, flow, moisture and temperature of the incoming gas.
In the effort to combat climate change, clean and sustainable fuels can be used to power our turbines directly or indirectly through various thermodynamic cycles.
