Technical information
Our technology is an example of Renewable Energy 2.0, driven by sustainable non- polluting, reliable renewables.
The challenge:
In the UK heating is 99% fossil fuel. Both hydrogen and heat pumps have been suggested as possible replacements for our gas boilers.
However, hydrogen has failed to live up to its expectations and is unlikely to be heating our homes soon and Heat Pumps are not a popular choice with many end users.
The UK government offers grants but there is little uptake due to the higher outlay and increase in electrical demand. This has a knock-on effect for EV charging due to off-grid seasonal variance by heat pump adoption.
High temperature heat pumps can have a big part to play in the transition, they have higher coefficients up to ten units of heat for one of electricity. They also don’t have to run 24 hours a day. So, we can be more selective about when energy is imported.
Heat pumps with a coefficient of three or below are not much cleaner than a boiler. They are products, not solutions. They can cause more problems than they solve.
Early adopting nations with little hydro power in the EU such as Denmark and Germany are now the EUs largest polluters.
The German government recently admitted that in hindsight heat pump adoption over infrastructure was an error.
H2oTurbines started as a renewable heating solution. A cleaner cheaper alternative to heat pumps. But we soon realised we could be sitting on the solution to everything renewable and it simply came down to the temperatures we could achieve.
The solution:
H2o Turbines Ltd’s technology is part of the solution.
It is a solution that empowers communities by allowing the retention of wealth and localised supply affecting energy costs. We put community needs ahead of everything else including security of future proofing supply and inflation busting costs.
H2oTurbines Ltd has spent seven years swimming against the tide of fossil fuels vested interest. We are proudly independent, utterly sustainable, and non-polluting. This gives us the moral high ground, so all our attention has been on the overwhelming factor in energy. PRICE!
Our unique selling point is that our technology is firmly based on good science and sound thermodynamic principles.
Our validation has been assisted from partnering Universities and Government sector Catapult. Every test result has been ground out through incremental improvement.
Small and medium scale testing and validation has led to utility scale testing commencing in April 2024 at Technical Readiness Level (TRL) 8.
BWoP is the enabling technology we use to turn an electric turbine into a thermal turbine without the need of precious metals in construction and use. Both are similar in operational and conversion efficiency. However, BWoP has a wider operational envelope which converts to more full load hours.
We make heat from wind using hydraulics. This means that we avoid using electrical decarbonisation resources and do not compete for wind turbine sites. The heat produced is cheap and easy to store at high and low temperatures.
BWoP will be available to wind turbine manufacturers giving an ability to build their own thermal turbines and create an identity based around our certified design under licence.

Thermal Wind
The wind provides rotation. This produces heat with a single mechanical conversion.
Heat is generated without compression, using liquid friction and sheer, generated within the transfer medium. There are few moving parts and no physical friction.
Thermal wind is a decentralised technology. No pylons or grid connections are needed.
The tiny amount of electricity required for control and remote monitoring is also self-generated.
Thermal wind is a sustainable, simple, modern wind pump design.
Thermal wind is designed to bolt onto any existing heating system via a heat exchanger in its simplest form, bringing savings in carbon and cost.
The scale is 150kw, 500kw, 1MW, 3MW and multiples of. Storage increases energy capacity.
Primary Wind
Primary wind is a carbon free, in operation, hybrid of thermal wind storage and a high temperature heat pump acting as security of supply.
By replacing passive sources of input heat at 8-13degrees C with 38-40 degrees C we get nine units of heat for one unit of electricity.
In any 24-hour period, if thermal wind has failed to deliver on tomorrows need, the heat pump is run to make up the shortfall, at night when the grid is nuclear, renewable and reasonably priced.
Intergrated Thermal
Is a hybrid of our Carnot battery technology, thermal wind, gas peaking plant waste heat and renewable energy excess. Multi vector renewable impact at a local / global scale.
The economic powerhouse of our heat networks.
Carnot batteries
Our Carnot batteries, 10MWh modules are used to build GWh battery houses.
We import negatively priced electricity only, as a service to the grid, storing it as heat at temperatures up to 1200-degree C.
We import gas peaking plant waste heat at temperatures up to 565-degree C.
We import thermal wind up to temperatures of 320-degree C.
To turn these high temperatures into low temperatures, suitable for distributed heat, we generate electricity when electricity is at its most expensive, using a steam turbine.
20MWh from a 1GWh battery for extended periods with our application.
With electricity up to £2400 MWh at these times, you can see why the Carnot battery is the economic driver for our system.
Summary
There are three interdependent energy sectors.
Our research has led us to the conclusion that electricity has a role to play in heating, as control and security of supply, but not in the role of lifting temperatures.
The largest impacting renewable in the UK over the last 20 years has been offshore wind.
The recent and growing availability of negatively priced renewable excess and the gas peaking plants brought in to combat winds infrequency, are the products we choose to hybrid with, this is an impossible hybrid for any other technology.
The science tells us that integrated thermal is state of the art. We are in the final stages of proving this beyond doubt. Official reporting at this level can take several years but our Energy Centre partner reporting will carry enough weight for our other collaborators to gain and retain confidence in what we are doing.
Integrated thermal brings opportunity from excess and infrequency, this will be the characteristic of a renewable powered world.
Resources are already failing to materialise in the EU.
Like the UK, other countries need a stake in Net Zero or Oil and Gas will continue to dominate. The entire world needs finished goods.
Resource rich economies need diversification.
Moving Forward
We are presently looking for 150kw, 500kw, 1MW and 3MW pilot projects leading to a larger adoption soon.
We are now entering a period of validation at utility scale. Technology readiness Level 8 is the zero to hero line, in terms of energy generation.
The documents generated will take us mainstream.

Executive Summary
H2oTurbines Ltd, founded in 2016 and based in the UK, develops practical, affordable low-carbon heating and cooling solutions.
Its patent-pending Thermal Wind Generation technology produces heat directly from wind, without electricity or combustion, offering a cost-competitive, sustainable alternative to fossil fuels.
Heat accounts for 54% of EU emissions, yet only 3% comes from renewables (less than 1% in the UK).
Conventional renewable solutions rely on electrification, which struggles to deliver high-temperature heat efficiently on a scale.
H2oTurbines approach avoids these inefficiencies, achieving ~90% conversion efficiency and temperatures up to 320°C, validated at TRL8 (by The Energy Technology Centre, East Kilbride) at a 200kW scale.
The technology is ready for utility-scale deployment and suitable for Industrial, Commercial, District Heating, Data Centres, and Desalination applications.
H2oTurbines is now seeking partners to scale to 1–3 MW systems and integrate hybrid solutions.
Introduction & Background
Heat is the largest contributor to energy-related carbon emissions, yet decarbonising it remains challenging.
Electrification and other renewables cannot easily compete with fossil gas for high-temperature, large-scale heat. Alternatives such as hydrogen, biomass, or nuclear face cost, supply, or complexity barriers.
H2oTurbines addresses this gap with Thermal Wind Generation, a non-combustive, scalable solution capable of delivering high-grade heat directly from wind.
Achieving TRL8 validation demonstrates readiness for industrial and commercial deployment.
Problem Statement
Industrial and commercial heat remains heavily dependent on fossil fuels, especially gas.
Electrified solutions face efficiency losses, high operating costs, and grid constraints.
Hydrogen and biomass are expensive, supply-limited, or environmentally constrained.
Nuclear provides scale but is capital-intensive and slow to deploy.
A scalable, low-cost, high-temperature heat solution is urgently needed to accelerate decarbonisation in the EU and UK.
