Saudi Arabia’s oil giant Aramco is working with Danish firm Topsoe and Siemens Energy on projects to reduce emissions, according to a statement. The agreements were revealed on the sidelines of MENA Climate Week in Riyadh under its lower CO2 push.

First up, a low carbon hydrogen plant: Aramco is in the process of finalizing an agreement with decarbonisation firm Topsoe to set up a lower-carbon hydrogen demonstration plant in the kingdom, the statement notes. The demonstration plant, which will be set up at the Shaybah Natural Gas Liquids (NGL) recovery plant, will have a production capacity of six tons of hydrogen per day. It will use renewable energy to produce lower-carbon hydrogen for use in power generation, resulting in having CO2 captured and sequestered.

Next, a DAC project: Aramco is also joining forces with Siemens Energy to develop a direct air capture (DAC) test unit in the country’s Dharan city, according to the statement. The test unit will have the capture capacity of up to 12 tons of CO2 annually and is set to be completed next year, paving the way for a larger pilot facility that will have a CO2 capture capacity of 1.25k tons per year.

A new sequestration method? Aramco said it has successfully piloted a novel CO2 sequestration method using in situ mineralization, which involves “dissolving CO2 in water and injecting it into volcanic rocks” in Jazan. It said that the method permanently converts CO2 into carbonate rocks.

And that’s not all: Aramco said it is also considering tapping into geothermal energy, with three potential areas on the west coast of the kingdom identified and mapped for the technology, according to the statement. It added that steps were currently underway to determine the geothermal resources at each of the selected areas.

All under one big plan: The announced projects come under Aramco’s target to reach net-zero Scope 1 and Scope 2 greenhouse gas emissions across its operations by 2050 and the kingdom’s 2060 carbon neutrality goal, according to the statement.
