Clean Development Technologies Limited98 Woodcroft,, Harlow, , United Kingdom

Welcome to Clean Development Technologies Limited. Please browse this website to learn about our first technology, Solid State Energy (SSE), generating electrical energy from low temperatures.

The SSE technology here presented is the brain child of two friends seeking to improve the way in which industry employs energy.

every megawatt of SSE installed in the UK would save about 450kg of carbon emissions, 650 kg in the United States based on the current generation mixes of those nations. According to our sales projections, this can amount to 13 tonnes of CO2 equivalence in the first year alone, 195 tonnes annually by the fourth year of deployment and 260 tonnes in total by the end of that year. And that’s just in the energy produced. If all of that was deployed in datacentre applications, the annual carbon saving is closer to 1,300 tonnes taking into account the energy that would have been consumed given the present status quo.

Clean Development Technologies Limited (CDT) is a start-up company established to develop technologies to generate clean energy and improve energy efficiency. Clean Development in this context can be viewed within the framework of the 'Clean Development Mechanism' whereby greenhouse gas (GHG) emissions are reduced due to the implementation of said technology.

The core CDT team consists of: 

PARVEZ HAMID
Parvez has extensive experience in Project Management, R&D, QC and hands-on engineering. He will be responsible for day-to-day lab/workshop operations, planning and running of tests and the administration of the facility (oversight). Parvez will be assisted by an admin assistant.

NEIL FAULKNER
Neil is responsible for the design and development of the concept. He will assist in overseeing the lab/workshop and will take a hands-on role in developing and testing the prototypes. Neil will be looking at all aspects of the technology, seeking the optimal solutions in terms of production, materials and design.

The extended CDT team consists of:

DR CLAUDIA PISAC PhD
Claudia has recently been awarded her PhD in engineering from Hertfordshire University. Parvez and Neil were extensively involved in her research work and fully endorse her aptitude and capabilities. Claudia will work with Neil in his responsibilities and perform many of the lab/workshop tasks, as a technician.

RAY THOMPSON
Ray is an R&D engineering consultant based at Imperial College, London. Ray will consult for the team in the design and development of the structural elements of the project, including materials, machining and assembly.

JEREMY WREN
Jeremy is a highly experienced and talented R&D engineer in electronics. He has developed numerous classified technologies for the UK Ministry of Defence amongst many other projects. Jeremy will consult for the team in designing the power handling, monitoring, communications and testing aspects of the project.

cdt's technologies

The company’s first technology project is the Solid State Energy system (SSE) which converts thermal energy, heat, to electrical energy. This is achieved through a refinement of a 190+ year old science using modern and commonplace materials.

The technology was 'discovered' by the team when researching alternative means to produce electrical power from fuels. The goal then was to eliminate the need for cumbersome and complex engines, turbines etc. and go straight to electricity.

APPLICATIONS

The technology here presented has been tested in the lab, at a small scale with hot water, solar and electric light infra-red radiation (IR) and sound waves, all creating electrical current registered on standard multi-meter equipment. The upshot of these tests is that the applications of the technology are quite broad and far-reaching.

The system has been shown to be effective with low temperatures (tested in hot water) and so the team has been exploring a number of relevant commercial spheres:
Wasted heat/energy efficiency: within industry and in particular the thermal power industry a great deal of thermal energy is wasted. Assuming a power plant is 50% thermally efficient [LINK], a 100MW plant wastes 100MW of thermal energy. If 20% of this was captured, the plant's efficiency would be boosted to 60%.
Many other industries lose similar amounts of energy: glass, ceramics, metal production and processing. All can recover some of that wasted heat for use in powering their systems.
A number of modern commercial sectors can be separated out from the above division and considered separately. In these the heat 'wasted' is a by-product of their processes and is destructive to their equipment.
Consider the data-center industry [LINK]. Here large amounts of thermal energy are created by the central processing units (CPUs) within the server blades. As much as 1500W (1.5kW) in heat is generated, enough to power a domestic kettle. This can destroy a CPU in seconds if not dissipated.
CDT has designed a version of the SSE to remove this heat by converting it to electrical energy (consider the law of energy conservation [LINK]). This electrical energy, while small mounts up with the many thousands of CPUs in the data-center. This energy is fed back into the center's systems thus saving the operator on cooling energy costs and subsequent GHG emissions.
Geothermal power: the SSE technology can be developed for deployment in such a manner that the hot medium (typically steam) does not need to be cycled to the surface and run through turbines before condensing and reuse. In the condensing phase of the process the operators of typical geothermal plants need to capture 'non-condensible' gases [LINK] which include some potent greenhouse gases (GHGs). This is cut out by the insertion of the power generation equipment within the boreholes.
Solar thermal energy: There are many solar thermal energy to electrical energy solutions available (differentiated from photo-voltaic). These use various means to generate electrical energy from sunlight. They typically utilize the Sun's IR to heat some fluid which in one manner or another drives a turbine .
The application of the SSE allows for the removal of complex and expensive mechanical power generation systems and thus the development of smaller installations. Further, the use of a hot medium can be leveraged to store energy after dusk, thereby producing solar sourced power after dark.

PROSPECTS

The team has already has hadmany fruitful discussions with potential clients and users in a number of sectors around the world. These have included major IT businesses with specific reference to data-centers and the emergence of Cloud Computing. In these settings, 40,000 x 300W SSE devices will be deployed to cool the data-center. server blades at very low operational cost. The only stopping factor for these clients right now, is their need to see test data and ‘kick the tires’ of a running unit.

Within the thermal power generation industry there is a groundswell of interest in efficiency boosting technologies. Thermal power from combustion is one area where the SSE can harness otherwise lost heat from cooling circuits and from exhaust flues. Within geothermal power the SSE can eliminate the need to bring steam to the surface.
