Hydram Research has developed a large-scale liquid piston oscillator, Hydram's Vertical Boiler. Reduced energy costs, lower emissions and best-in-class efficiency (COP) compared to modern LHP+MVR / HTHP solutions.
Up to half of industrial energy is never used but simply discarded to surroundings in cooling towers, radiators or poured down the drain as cooling water. Increasing cost of energy is industry's largest challenge.
Hydram Research's engineers have discovered and developed a new and more efficient way to boil water and generate industrial steam. The elegant open oscillatory approach is a departure from the method we're all accustomed to, crudely attacking the liquid with heat until it bubbles - how we've boiled water since we lived in caves.
In simple terms, our novel boiling method can be described as exciting and maintaining oscillations of a warm multi-ton liquid piston so that it travels several meters up and down a thick pipe.
The process consists of three stages:
Low pressure steam is generated in the wake of the falling liquid piston, which drops due to its weight and pressure conditions in the wider side tank.
After dropping several meters the liquid piston naturally rushes back up, rapidly squishing the steam. The trick is not to allow the steam to condense back to droplets, but to let the piston pressurize and heat it up - similar to air in a diesel engine.
About half way up, the steam's pressure forces a valve to open and the steam is ejected into the steam header to do useful work - like district heating, cooking food, or creating paper.
Q: Wait, that seems complex - why not just heat the water?
A: One of the advantages of doing it this way is that most of the steam's energy is derived from a process called "evaporative cooling". The input energy is mainly just to keep the system and the liquid in it warm - not to maintain the oscillation.
Higher COP than LHP+MVR or HTHP alternatives.
+200 kWth up to 1 MWth per unit. Multiple units will be arranged in series and in parallel to fully extract available waste-heat and meet larger industrial steam demands.
Lower capital costs (€/MWth) due to fewer moving parts and less complexity. Furthermore lower installation, maintenance and lifetime costs are expected.
Requires small footprint and is flexible in terms of heat source (cooling water / flue / other) and temperature range, allowing for easier integration into existing industrial sites.
Significantly reduces emissions. No combustion, no refrigerants, and no rare-earth materials — water is the only working fluid.
Increased energy self-reliance. Standalone hardware requiring no external connections for operation.
Hydram was founded in December 2022 to develop a new method of generating industrial steam using 'large-bubble' cavitation. Generously supported by tech-savvy angel investors and family offices from Iceland and the UK, as well as domestic R&D grants, we've rapidly built several successively larger prototypes and developed advanced computer models to simulate the process.
Hydram's newest prototype weighs several tons, is the size of a three-story building, and ejects steam like a small geyser.
