Leveraging Heat Pump Technology to Convert Heat to Hydrogen or Electricity
HALOcline presents Reverse Electrodialysis Heat Pump (RED-HP) technology—an innovative energy solution that harnesses salinity gradients to produce clean hydrogen and/or electricity. Unlike conventional reverse electrodialysis (RED), which depends on natural seawater and freshwater, RED-HP operates in a closed-loop system, eliminating location constraints while maximizing efficiency.
By integrating MultiSource heat pump technology, RED-HP not only generates renewable energy but also utilizes low-grade waste heat, reducing reliance on external power sources. This breakthrough technology offers a scalable, carbon-neutral alternative to traditional energy generation, with the added benefit of cooling.
Inside the RED stack
Reverse Electrodialysis (RED) is a process that generates electricity by harnessing the chemical energy from salinity gradients. It works by placing alternating anion (AEM) and cation exchange (CEM) membranes between saltwater and freshwater streams. As ions naturally move across the membranes, they create an electric potential, which is converted into usable power. This clean, renewable energy source is ideal for continuous, sustainable energy production
"Supercharging" RED with a Heat Pump
RED-HP utilizes ion exchange membranes to facilitate ion movement, generating an electric potential that produces renewable electricity. At the same time, the system efficiently produces hydrogen, which can be stored and later used to power homes, vehicles, and other energy applications, providing a versatile and sustainable fuel source.
Unlike traditional RED systems, RED-HP actively regenerates its salinity gradient using a heat-driven process, significantly boosting power output while maintaining efficiency in diverse environments.
One of the novelties of RED-HP is its ability to cool indoor spaces as a natural byproduct of its energy conversion process. Instead of discarding excess heat, RED-HP repurposes it to maintain the salinity gradient, a crucial step for generating hydrogen and electricity. This thermal process inherently absorbs heat from its surroundings, resulting in a cooling effect.
By leveraging waste heat for energy production, RED-HP passively cools indoor spaces, reducing the need for separate air conditioning systems. This dual-function capability lowers overall energy consumption, enhances efficiency, and provides a sustainable alternative to conventional cooling—all while producing clean hydrogen and electricity.
With its ability to convert waste heat into power, generate hydrogen fuel, and provide cooling simultaneously, RED-HP redefines sustainable energy by maximizing efficiency and minimizing environmental impact.
Hydrogen Storage: Power on Demand
With the patented RED-HP system generating clean hydrogen, HALOcline also provides a flexible storage solution, allowing hydrogen to be stored safely in specialized cylinders and accessed on demand, year-round. This ensures a reliable energy source, whether for powering homes, vehicles, or industrial applications. The storage system is scalable, adapting to different energy demands, making it easy to expand capacity as needed. With hydrogen ready when you need it, RED-HP offers a practical, renewable alternative to conventional energy sources.
