2 Environmentally friendly For high temperature applications, AQYLON s organic working fluids have a very low Global Warming Potential (3-20). Rugged AQYLON s ORC modules are designed for durability and fit into standard containers, allowing for modular deployment. Efficient AQYLON s ORC modules apply cutting edge technology to maximize efficiency according to the heat source. AQYLON holds four patents related to turbines and ORC technology, and eight more are pending. Heat recovery from diesel engines and gas turbines ORC modules are available for solutions up to 10 MWe. AQYLON s ORC modules convert waste heat contained in exhaust fumes into electricity. Our Organic Rankine Cycle (ORC) technology increases electricity production from engines or gas turbines by around 10%. Because the heat to drive the ORC cycle comes from the exhaust fumes, fuel consumption is unaffected. When recovering exhaust fumes, a heat exchanger must be placed on the flue gas ducts to collect the heat and transfer it to a thermal oil loop that will feed the ORC module.

ORC Heat Recovery: Flue gas from gensets AQYLON ORC Module Gas turbines u Heat exchanger The heat output of gas turbines can be recovered in the form of high pressure and high temperature steam. It is possible to significantly increase the electrical output of the assembly and improve the overall electrical efficiency by installing an ORC solution to use this steam. Gas Turbine By-pass Cheminey Electricity grid Dry Aerocoolers water chiller Recovery of the heat output in the form of high pressure and high temperature steam.

3 ORC technology avoids corrosion issues and turbine wear associated with steam turbines - such as blade erosion and high speed operation - resulting in low maintenance costs. Our ORC modules can rapidly ramp up to match changing power needs, from 60% up to 120% of nominal capacity. Rugged design ensures a life expectancy of over 25 years.

The vaporized fluid enters the regenerator(2) to give its remaining energy to the liquid organic fluid. The vapor is then condensed in a condenser(2) which is supplied with cooling water. The condensed fluid is then pumped(3) into the regenerator(2) and finally into the evaporator(1) to close the circuit. AQYLON ORC modules are preassembled in our facility workshop near Paris in two 40ft containers for the 1MW unit.

5 Depending on the territory and the applications, if there is no will or capacity to invest in an ORC solution, AQYLON offers a fully financed solution where all costs and risks associated with our ORC modules are assumed by external investors. In exchange, the client provides AQYLON with a Power Purchase Agreement (PPA). The client agrees to purchase electricity produced by AQYLON s ORC modules at a price that is 5 30% below the plant electricity price or plant generation cost. At the end of the PPA period, the client can renew the PPA or purchase AQYLON s ORC modules at a greatly reduced price. Our Project Financing Model: Creation of a Special Purpose Vehicle (SPV) that owns the solution Sale of electricity or heat at an offtake price guaranteed for the long term Any performance risks are carried by the SPV No impact on the balance sheet of the client ( Zero Capex/Opex ) Partitioning of the added value between the client and the investors This arrangement allows projects with longer payback times to be financed There are three possibilities at the end of a 7-10 year PPA contract: 1) There is no contract renewal: The SPV that owns the project has 6 months to take back its equipment. 2) The PPA is renewed: New electricity pricing and conditions will be determined for the renewal period. The minimum contract renewal period is 5 years. 3) Buyback option: The customer can purchase the ORC equipment at a greatly reduced price. It is also possible to acquire the ORC solution before the end of the PPA.

6 AQYLON designs, manufactures and installs complete ORC solutions (Organic Rankine Cycle) for the production of electricity from high temperature heat sources, at a competitive price. AQYLON proposes standard and tailor made solutions up to 10MWe. Targeted applications include recovery of waste heat from engines, recovery of industrial waste heat, biomass power plants, geothermal and solar thermal sources. AQYLON offers two business models. Customers may invest through the usual product purchasing process. For customers not willing to invest, we have a ZERO CAPEX/ OPEX option with turnkey solutions fully financed with the sale of the produced electricity, at a lower price than the grid (PPA).
