Why Green Initiatives Matter for Middle East Oil

Implementing environmentally friendly practices in refineries and across oil and gas operations has become increasingly important for multiple reasons:

• Comply with regulations: Countries around the world are implementing stricter environmental regulations that Middle East exporters will need to comply with. Adopting green initiatives helps meet current and upcoming legislation.

• Meet investor and societal demands: As per a recent survey, over 75% of Middle Eastern investors now consider ESG performance before making investment decisions. Prioritizing sustainability meets growing demands from financiers and the public.

• Maintain competitiveness: With the global push towards renewables and greener energy, oil companies need to reduce emissions and environmental impact to remain competitive. Implementing green technologies can help attract talent and investment.

• Reduce costs: Sustainable practices around energy, water, and waste management can significantly cut costs at oil refineries. Environmental efficiencies translate directly to operational savings.

Key Green Strategies Being Implemented

Middle East oil companies are targeting sustainability through various initiatives across refineries and production facilities:

1. Improving Energy Efficiency

Increasing energy efficiency is among the top priorities, as it directly reduces emissions and costs:

• Process optimization: Refineries are utilizing process simulation software and digital optimization solutions to identify efficiencies across plant operations. This allows them to minimize energy requirements without impacting output.

• Waste heat recovery: Capturing waste heat from refinery processes significantly improves energy efficiency. Waste heat can be used to produce electricity, steam, or hot water for heating applications.

• Cogeneration plants: Many facilities are installing cogeneration units that produce both electricity and usable heat from the same fuel. This leads to substantial energy savings compared to conventional separate methods of power and heat generation.

2. Water Conservation and Reuse

Water usage is another big focus area. Key initiatives adopted include:

• Water management systems: Monitoring water consumption and leaks in real-time through sensors and analytics helps optimize water usage across the plant. For example, Saudi Aramco has implemented water management systems expected to save up to 500,000 cubic meters per year.

• Treating and reusing wastewater: Instead of discharging wastewater, refineries are increasingly treating it with membrane bioreactor (MBR) systems and reusing it for utilities. This reduces both water needs and effluent volumes.

• Seawater usage: Utilizing seawater for cooling towers and even some unit processes reduces reliance on potable water supplies. Desalination units are being added to facilitate seawater use.

3. Renewable Power Integration

Refineries located in the Middle East have abundant access to solar energy and are ramping up renewable power generation:

• Solar energy: Many downstream facilities are deploying large solar photovoltaic plants. Some companies have set goals to meet 20-25% of their power demand from solar energy within 5-10 years.

• Waste to energy: Oil production and refining generates significant volumes of residue and byproduct gases like methane which can be utilized for onsite power generation. Capturing these waste resources offsets grid electricity usage.

4. Carbon Capture and Storage

Carbon capture, utilization, and storage (CCUS) is an emerging area that large Middle Eastern oil companies are piloting:

• CCUS facilities: Directly capturing CO2 emissions from hydrogen plants and other gas streams for subsurface storage or utilization in enhanced oil recovery. This prevents greenhouse gases from being released into the atmosphere.

• Scaling up deployment: CCUS is still in initial stages but is expected to grow significantly. Saudi Aramco and SABIC recently announced a $6 billion development with capacity to store up to 9 million tons of CO2 per year.

Examples of Green Projects by Leading Companies

The above table summarizes renewable energy, carbon capture, water sustainability, and efficiency commitments and projects from four leading national oil companies in the Middle East. While the specific initiatives vary, all four companies are strategically moving to reduce environmental footprint through similar means.

Challenges With Adopting Green Technologies

While environmental sustainability is clearly being prioritized, key challenges still remain around accelerating adoption of green technologies:

• High costs – Renewable energy, carbon capture, and other technologies require major upfront infrastructure investments. Getting approvals for large capital investments justified only on sustainability merits faces hurdles.

• Policy incentives – Unlike US and Europe, there is still a lack of strong policy incentives around emissions reductions and energy efficiency in the Middle East. Regulatory drivers can help address stakeholder objections around costs.

• Mindset shift – Being historically focused only on oil and gas production for revenue, many companies still have an organizational culture and leadership mindset tuned mainly to technical instead of environmental issues. An internal cultural transformation is essential.

Outlook for Green Transitions in Middle East Refineries

The examples and data provided throughout this article illustrate that sustainability is clearly rising in prominence across Middle East oil and gas entities. Ambitious renewable energy commitments combined with carbon capture and efficiency drives demonstrate earnest intentions around improving environmental performance.

Industry leaders have also noted that sustainability is moving beyond just a concept and translating into real decisions:

“We used to have within Saudi Aramco something called nonsystem opportunities, which means good ideas that have no chance to be implemented. Renewable used to be one of those nonsystem opportunities. Today it is embedded into the system.” – Amin Nasser, President and CEO, Saudi Aramco

A combination of pressures from stakeholders, technology maturity, and especially evolving mindsets are expected to drive faster adoption of green technologies throughout Middle East refineries in the coming decade. Climate action is increasingly being viewed not as a cost center but as a critical investment to guarantee continued success.
