Beyond Reverse Osmosis: How Hybrid MED+RO Systems and Green Energy are Securing Algeria’s Water Future

Abstract Algeria’s pure reverse osmosis (RO) desalination systems face serious vulnerabilities: increasing turbidity events and frequent membrane replacements threaten operational stability, resulting in 1,680 hours of downtime annually across active plants. As the Mediterranean warms 20% faster than the global average, water security requires urgent innovation. This article proposes a hybrid MED+RO technology (1/3 thermal + 2/3 membrane) to ensure operational resilience. If RO shuts down, MED continues independently at 33% capacity, guaranteeing minimum supply. Although hybrid systems require a 28% higher capital investment, break-even is reached in year 16 due to reduced membrane replacement costs. Optimized pre-treatment with ultrafiltration … Continue reading →

Desalination at the Heart of Algeria’s Green Hydrogen Future: Water Security as a Strategic Energy Lever

Algeria stands today at the crossroads of two defining transitions: the global shift toward low-carbon energy systems and the intensifying pressure on water resources across arid and semi-arid regions. In this dual transformation, green hydrogen has emerged not only as an industrial opportunity but as a strategic lever capable of reshaping the country’s energy model, export structure, and environmental trajectory. Yet, at the heart of this hydrogen ambition lies a critical enabler that is too often underestimated: desalination. Green hydrogen, produced through water electrolysis powered by renewable electricity, is increasingly recognized as a cornerstone of global decarbonization strategies [1,2]. Unlike … Continue reading →

Green Hydrogen: Global Dynamics, MENA Perspectives and Algeria’s Decarbonization Strategy

Global energy systems are undergoing a structural transformation driven by the urgency of climate change mitigation, long-term sustainability concerns, and the need to reduce dependence on fossil fuels. The Paris Agreement and subsequent national commitments to carbon neutrality by mid-century have reinforced the necessity of deep and rapid reductions in greenhouse gas emissions across all sectors of the economy. Although renewable electricity generation—particularly solar photovoltaics and wind power—has expanded significantly over the past decade, the electrification of final energy demand faces intrinsic limitations in sectors characterized by high-temperature industrial processes, energy-dense fuels, and long-duration storage requirements [1]. Green hydrogen has … Continue reading →

Energy Transition in Algeria: Concrete Levers to Move from Ambition to Action

Algeria stands at a critical energy crossroads. Long known as one of Africa’s leading producers and exporters of hydrocarbons, the country is now attempting to balance the twin imperatives of maintaining economic stability from oil and gas revenues while accelerating a shift to a cleaner, more diversified energy system. With global pressure to decarbonize mounting and domestic energy demand rising rapidly, Algeria’s energy transition is no longer just a vision, it is becoming a necessary strategic priority. But turning ambition into tangible results requires a careful blend of policy frameworks, incentives, partnerships, and effective implementation. Algeria’s renewable energy potential is … Continue reading →

The Middle East and North Africa (MENA) offer impeccable weather conditions to develop renewable energy continuously all year round. There are currently over 1500 wind and solar photovoltaic (PV) projects in the area with a producing capacity of over 20GW[1] and these numbers are expected to grow exponentially in the forthcoming years[2]. Recently, hydrogen has received an unprecedented attention in the global energy scenery. Over 30 countries have revealed their hydrogen strategies, and more are expected to follow. Just in the MENA region, 10 countries have ambitions in developing the technology and are prepared to invest in related projects, in … Continue reading →
