Green Independence's New Artificial Leaf (NAL) combines the latest innovations in photovoltaics and electrochemistry.
Soleidon provides an effective and sustainable method to purify water.
The Electrochemical Module (ECM) uses the electrolysis of water to produce green hydrogen using solar energy as the primary power source.
Green Independence's New Artificial Leaf (NAL) combines innovations in energy, water and electrochemistry.
A new era of clean energy
Our all-in-one, modular system not only converts solar energy into electricity—it also purifies wastewater and generates green hydrogen, all within a single device.
One hectare of NAL
exposed to
minutes of sunlight
can purify up to
m3
of wastewater
and produce
up to
of green hydrogen
Soleidon is the green energy production and water purification module.
It uses solar panel dissipated heat to purify water, making it adaptable to several applications.
Anion Exchange Membrane electrochemical cell (ECM)
It produces green hydrogen using an anion exchange membrane (AEM) electrode assembly and low-noble-metal catalysts, optimizing costs.
The two modules can be used independently of each other or integrated into the NAL.
Key features of NAL
Decentralized approach
Enables the production and storage of green energy without relying on traditional power grids.
Integrated Functions
Water purification and green hydrogen production are combined in a single technological solution.
Cost-efficient green hydrogen production
Thanks to the ECM, we can lower production costs to as little as €1/kg.
Modular Flexibility
The system is adaptable to a variety of needs—from industrial-scale operations to remote, off-grid communities.
Built-in Safety
The system operates at low pressures, low voltage, and low temperature—under standard safety conditions—making it as safe to use as a household appliance.
Accessibility
The system is easily deployable across industrial facilities and heavy transport infrastructure such as ports, airports, railway, or refueling stations.
Techno-Economic Goals of NAL Technology
NAL technology aims to achieve important techno-economic objectives to revolutionize the green hydrogen production sector.
Our main objectives are:
Reduce the cost of green hydrogen from the current market benchmark of €8/kg to as low as €1/kg.
Exploiting gains from secondary products (such as pure water), waste reduction, and economy of scale.
Bring the cost of purified water to zero, or even create a net economic benefit.
Co-generate solar power during water purification, transforming a traditional cost into a source of value.
Cut the cost of electricity to below €0.1/kWh.
Use the benefits of water purification to reduce energy costs, ensuring a sustainable and cost-effective approach.
