Swiss firm to develop Aramco’s carbon capture tech for marine vessels

Swiss climate tech firm Daphne Technology has obtained permission from Saudi Aramco Technologies, a subsidiary of oil and gas giant Aramco, to develop and commercialise its mobile carbon capture (MCC) technology.

MCC technology works by taking a vehicle’s exhaust gases and passing it over a solvent to capture carbon dioxide (CO2). The CO2 is then compressed to be stored in a tank onboard the vehicle.

The energy to power both the CO2 capture and the compressor units is generated by an energy recovery system that converts the engine’s wasted heat to energy. The stored CO2 can be offloaded later for use in a variety of industrial and commercial products.

The technology has already proven successful in passenger road transportation, and recently captured up to 40% carbon in a heavy-duty truck, according to Daphne Technology.

Although marine vessels consume significantly more fuel, the company believes that the technology can be adapted and developed for deployment on large commercial vessels.

Carbon capture technology is a crucial tool in reducing carbon from “hard-to-abate sectors including the deep-sea maritime sector,” Daphne Technology says.

Saudi Aramco Technologies’ chief executive Abdullah S. Dhuwaihi echoes the view and believes that MCC technology will “support the decarbonisation of the maritime sector.”
