The rise in CO2 emissions is causing major problems like glaciers melting and sea levels rising. To help tackle these issues, the DESOLINATION project introduces a cutting-edge power cycle for desalination systems, using innovative CO2-based mixtures as the next generation of working fluids. This paper highlights the project’s benefits and the technical hurdles overcome in designing the necessary machinery.<\/h5>[\/et_pb_text][et_pb_button button_url=”https:\/\/onepetro.org\/SPEADIP\/proceedings-abstract\/23ADIP\/1-23ADIP\/D011S017R002\/534234″ url_new_window=”on” button_text=”Read publication” _builder_version=”4.27.4″ _module_preset=”default” button_text_color=”#FFFFFF” custom_margin=”1rem||1rem||true|false” custom_padding=”0.5rem|2.5rem|0.5rem|1.5rem|true|false” hover_enabled=”0″ global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″][\/et_pb_button][et_pb_text _builder_version=”4.25.1″ _module_preset=”default” text_font=”–et_global_body_font|300|||||||” text_orientation=”justified” global_colors_info=”{}” theme_builder_area=”post_content”]

Key factors were considered when developing the thermal cycle and choosing the working fluid, including safety, environmental impact, material compatibility, and efficiency.<\/p>[\/et_pb_text][et_pb_text _builder_version=”4.25.1″ _module_preset=”default” text_font=”–et_global_body_font|300|||||||” text_orientation=”justified” global_colors_info=”{}” theme_builder_area=”post_content”]

The system relies on turbomachinery\u2014specifically a pump and an expander\u2014to recover heat from a primary solar-powered cycle. This setup allows flexible heat production while simulating different solar conditions.<\/p>[\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” text_font=”–et_global_body_font|300|||||||” text_orientation=”justified” hover_enabled=”0″ global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]

One major challenge was picking the right CO2 blend to balance efficiency and practicality. By adding a \u201cdopant\u201d to CO2, the fluid\u2019s properties could be adjusted, allowing the system to use a pump instead of a compressor. This makes heat exchange more efficient by keeping the fluid at a temperature suitable for the solar heat source. Several dopants were tested to find the best one for efficiency and compatibility.<\/p>[\/et_pb_text][et_pb_text _builder_version=”4.25.1″ _module_preset=”default” text_font=”–et_global_body_font|300|||||||” text_orientation=”justified” global_colors_info=”{}” theme_builder_area=”post_content”]

Material compatibility was another challenge, as the equipment needs to handle temperatures as high as 550\u00b0C, typical for solar-thermal power technology. The final dopant choice was a trade-off between reducing corrosion and maximizing performance.<\/p>[\/et_pb_text][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” text_font=”–et_global_body_font|300|||||||” text_orientation=”justified” hover_enabled=”0″ global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]

The DESOLINATION project aims to launch its first pilot plant in 2025, offering competitive solutions with solar-thermal efficiency above 42%, efficient freshwater production, and up to 70% lower CO2 emissions per cubic meter of desalinated water compared to current systems.<\/h6>[\/et_pb_text][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” text_font=”Roboto|300|||||||” hover_enabled=”0″ global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]
