From Lab to Global Impact: Nigerian Chemist Leads Breakthrough in Salt-Water Battery Innovation

By Uduak Gbenga

Nigeria’s developmental journey has long been defined by a paradox of abundance a nation rich in natural resources yet burdened by persistent energy insecurity. Across its cities and rural landscapes, unreliable electricity continues to hinder industrial output, disrupt healthcare delivery, and compromise food preservation. For an economy where agriculture employs more than a third of the workforce, post-harvest losses due to inadequate cold storage remain one of the most pressing and costly challenges.

As policymakers search for sustainable solutions to bridge the energy gap, one of Nigeria’s own scientists has emerged at the forefront of global clean technology innovation. Bamise Israel Egbewole, a Nigerian chemist and graduate of the University of Ibadan, is pioneering a revolutionary high-power salt-water battery system a green energy alternative capable of powering cold storage facilities and off-grid infrastructures across Africa and beyond. His leadership in a multinational research initiative at Aldelano Organic Foods (U.S.) is positioning African scientific ingenuity as a key driver in the global clean energy transition.

Energy Access and the Nigerian Dilemma

Despite significant investment in grid expansion, over 85 million Nigerians nearly 43% of the population still lack reliable electricity access. This deficit extends beyond households; it undermines agribusinesses, fisheries, and small-scale food producers who rely on refrigeration for survival. The Food and Agriculture Organization (FAO) estimates that Nigeria loses nearly 40% of its perishable produce annually to inadequate storage, amounting to over ₦3 trillion in lost revenue.

At the intersection of these challenges lies an opportunity: to develop decentralized, clean, and affordable energy storage systems that can sustain cold-chain operations without dependence on diesel generators or costly lithium batteries. That opportunity became the mission of Egbewole’s team a mission that has now yielded a transformative prototype.

“Lithium-ion batteries changed how the world stores energy,” Egbewole told BusinessDay. “But they’re expensive, environmentally problematic, and not scalable for developing regions. We wanted a safe, sustainable alternative that uses resources as common as seawater.”

The Birth of a Clean Energy Alternative

At Aldelano Organic Foods, a U.S.-based company renowned for its off-grid cold storage technologies, Egbewole serves as Research Consultant and Team Lead for the Salt-Water Battery Development Project. His mandate: to design a battery that can sustainably power cold storage facilities for agricultural produce particularly in off-grid and rural areas across West Africa and the U.S. Midwest.

Working with an international team of engineers Joseph, Leonard, Jake, and Blake Egbewole guided the electrochemical design, testing, and cost optimization of the salt-water battery prototype. The technology leverages sodium-based electrolyte chemistry rather than lithium or lead-acid systems, eliminating the use of toxic metals while ensuring environmental compatibility.

Using his background in industrial and inorganic chemistry, Egbewole led the optimization of electrolyte formulations, current density control, and electrode material performance. The team’s breakthrough design achieved high energy density and extended charge-discharge cycles, while maintaining thermal stability and non-flammability, a critical safety advantage over conventional battery systems.

“Our approach merged laboratory science with real-world economics,” Egbewole explained. “We wanted to engineer something that rural farmers could afford, maintain, and rely on without complex infrastructure.”

Innovation Driven by Purpose

The project’s vision extends far beyond engineering success it addresses a structural issue at the heart of Nigeria’s agricultural economy: the lack of cold storage infrastructure. By integrating the salt-water battery into Aldelano’s Solar ColdBox system, Egbewole’s work has enabled a 40% reduction in operational costs and significantly improved storage lifespan for perishable produce such as tomatoes, peppers, fish, and dairy.

This innovation bridges energy and agriculture, empowering smallholder farmers with off-grid preservation technology that can stabilize income, reduce spoilage, and enhance food security. It represents a rare case of African-led technology solving a global sustainability challenge clean, accessible, and economically scalable energy storage.

“Food security is energy security,” Egbewole emphasized. “If we can store food safely, we reduce poverty, improve nutrition, and strengthen the agricultural value chain.”

From Nigeria to the United States: A Model of Collaboration

Egbewole’s collaboration with Aldelano Organic Foods (U.S.) exemplifies the power of cross-border scientific partnerships. As the team lead, he coordinated experimental design between facilities in Nigeria and the United States, leveraging his expertise in process optimization and electrochemical modeling.

Using Excel-based cost modeling and data-driven scenario analysis, he identified low-cost material substitutions that reduced production costs by 30% without compromising battery efficiency. This integration of scientific precision and economic foresight underscores his rare ability to bridge laboratory research with commercial viability a skill set that has made him a respected figure in industrial sustainability circles.

“Science must be inclusive,” he said. “Innovation should not stop at discovery it should reach the communities that need it most.”

Technical Excellence and Environmental Rigor

Unlike conventional lithium-ion batteries that rely on scarce minerals such as cobalt and nickel, Egbewole’s salt-water battery uses non-toxic, widely available materials, making it both safe and recyclable. The system’s electrolyte solution based on sodium chloride demonstrates strong ionic conductivity while minimizing corrosion and leakage.

Through continuous iterative testing, his team improved charge retention efficiency by over 20%, achieving performance metrics that rival early-generation lithium batteries at a fraction of the cost. In addition, the battery’s modular design allows scalable configuration, enabling usage across diverse applications from small farm coolers to large cold-chain hubs.

The design’s environmental impact is minimal. The use of aqueous electrolytes ensures the battery poses no fire risk, while its biodegradable components reduce long-term waste generation. As part of Aldelano’s sustainability framework, lifecycle assessments were conducted under Egbewole’s direction to validate the system’s carbon footprint reduction relative to comparable lithium and lead-acid technologies.

Leadership Beyond the Laboratory

Leading a multinational research team presented unique operational challenges—time zones, experimental calibration differences, and divergent testing standards. Yet Egbewole’s background in industrial chemistry, research management, and quality assurance positioned him to harmonize processes and motivate productivity across technical disciplines.

His leadership style, marked by analytical discipline and mentorship, fostered collaboration between materials scientists, electrochemists, and systems engineers. Under his supervision, the team advanced the salt-water battery project from proof-of-concept to pilot-scale testing, now progressing toward commercial rollout across select agricultural regions in West Africa and the U.S. Midwest.

“Innovation thrives where science meets management,” Egbewole said. “We didn’t just build a product; we built a model for sustainable collaboration.”

Socioeconomic Implications: A Battery for Development

The potential impact of this breakthrough extends deep into Africa’s development narrative. Reliable cold storage is the backbone of modern food supply chains. By eliminating the dependence on costly diesel generators, the salt-water battery can reduce operating costs by up to 40% for agribusinesses and cooperatives.

More importantly, it democratizes access to energy storage, enabling women-led farming enterprises and rural entrepreneurs to preserve and trade their products beyond harvest cycles. The system supports Nigeria’s broader Sustainable Energy for All (SE4ALL) initiative and aligns with Goal 7 of the UN Sustainable Development Goals (Affordable and Clean Energy).

Economic modeling conducted by Aldelano projects that nationwide adoption of salt-water battery systems in agricultural cooperatives could save up to ₦500 billion annually in post-harvest losses while creating new manufacturing and maintenance jobs.

“The salt-water battery isn’t just a device,” said an Aldelano spokesperson. “It’s an ecosystem of opportunities from material sourcing to technician training led by African innovation.”

Scientific Excellence Rooted in Nigerian Training

Egbewole’s foundation for this global achievement was laid in Nigeria’s academic system. His Bachelor’s degree in Chemistry from Adekunle Ajasin University introduced him to environmental and analytical research, culminating in a groundbreaking undergraduate study on pesticide sorption in Nigerian soils a work that built his expertise in chemical modeling and surface interactions.

Later, during his postgraduate studies at the University of Ibadan, he expanded his focus into industrial and inorganic chemistry, exploring the green synthesis of silver–nickel bimetallic nanoparticles using natural plant extracts. These early experiences honed his skills in reaction optimization, spectroscopic characterization, and sustainable materials engineering competencies that directly underpin his leadership in clean energy systems today.

A New Chapter in African Scientific Leadership

Egbewole’s career trajectory reflects a broader shift in Africa’s research landscape from dependency to global participation. His leadership at Aldelano embodies a new generation of African scientists who design, lead, and export innovation, rather than merely consume it.

In global forums, his work has been cited as an example of “localized sustainability innovation” technology that responds to both global decarbonization targets and African developmental realities. By translating laboratory discovery into scalable business impact, he demonstrates the value of embedding African expertise within multinational R&D ecosystems.

“Africa’s challenge has never been intelligence,” he reflected. “It’s opportunity. When given the right platform, we don’t imitate innovation we accelerate it.”

Looking Ahead: Building Energy Resilience from the Ground Up

As global demand for renewable energy grows, the implications of Egbewole’s salt-water battery extend well beyond agriculture. Its modular design and non-toxic composition make it adaptable for rural electrification projects, telecommunication backup systems, and even domestic power storage in emerging economies.

Ongoing collaborations between Aldelano and regional partners aim to establish pilot manufacturing hubs in Nigeria, Ghana, and Kenya. These initiatives could mark a turning point in Africa’s clean energy ecosystem transforming the continent from an importer of energy technologies to a producer of them.

Egbewole remains characteristically grounded:

“Sustainability begins when technology serves the most underserved,” he said. “If a farmer in Oyo or Kano can preserve their crops without losing power, that’s true innovation.”
