• Built and tested in the US in the 80s

• Our solution is application for ORC at medium pressure

of current high performance supercritical steam rankine cycle

(used in more than 500 modern coal fired power plants)

• Subcritical cycle dual pressure ORC

• Subcritical cycle single pressure ORC

Linde & CryostarSub and Supercritical cycle

Advantages of medium pressure supercritical ORC

• Recovering the largest amount of heat with minimized energy losses


8

• Smoother and easier evaporation process compared to the conventional

design which would need preheater, vaporiser and superheater

• Easy control: no risk of ingress of liquid inside the turbine

• Standard execution of radial turbine

• High pressure operation reduces the frame size of the turbine

• Extended operational testing for long term stability

• CO2 utilization for tests and R&D programs

LindeAlgea References

Algea to Biofuel: Sapphire Energy & Algenol Biofuels

• Method utilizes algae, CO2, salt water and sunlight to directly produce 3G bioethanol and other 3G biofuels.


12

• Optimal and cost-efficient supply of CO2 key success factor.

• CO2 from fossil fuel sources.

• Fuels or chemicals from algae are a promising way of reducing

green-house gas emissions.

• Sapphire Energy: open-pond, algae-to-fuel cultivation systems.

• Algenol: photobioreactor technology
