Here at Hallidays we are also passionate about bringing renewable power to remote and developing nations. 1.5 billion people lack access to electricity (ref: WHO) and these can mainly be found in Africa’s and Asia’s rural areas. The infrastructure for long distance transmission of electricity often does not exist in these areas and the construction of large-scale power plants is not economically feasible.
Working closely with charitable aid projects, our mission is to use our knowledge and experience of water, to bring sustainable energy and clean drinking water to developing nations. We believe that electricity can lead to education and skills development whilst clean water brings about sanitation and health. These are the cornerstones to enabling communities to thrive with abundance just as we have had the opportunity to do.
Hallidays envisage “battery stations” where locals can pay a small rent to collect a fully charged (by hydropower), long-lasting and portable battery. When the battery is dead, they bring it back and swap it for a new one. They can power low energy fridges, LED light bulbs and other electrical items so they can read, work and cook at night.
Water filtration units can also operate from the ever-flowing source of energy provided by micro- and pico-hydropower units. Communities tend to develop close to the water’s edge, opening up opportunities to use the water sustainably for power and once filtered, as a potable water source.
In this changing world, the hydropower sector has to develop solutions that work within tighter budgets and more isolated, remote or difficult to reach areas.
Here we are currently working on a number of very exciting and cutting edge projects:
Pico is the term used for hydro electric power generation of under 5kW.
There is an ever-growing need and opportunity to supply electricity to under served populations in developing countries and remote locations. This is where the Pico Barrel comes into play – a new ‘plug and play’, Pico sized turbine for use in fast flowing streams and rivers to power local electronics and water filtration etc.
Extensive R&D work into the output, size, shape, flight design, and material, taking into account durability, reliability, cost, weight, water resistance etc. has been carried out by our R&D team.
We have a prototype under test in Manchester and patenting has begun. Hallidays hope to deploy this lightweight, easily shippable system in developing nations across the globe.
Hallidays Hydropower believe that the building of new, large scale dams is unnecessary given the capability of our innovative systems for effectively ‘plug and play’ solutions for existing water impoundments. We believe that retrofit hydropower solutions will be the future of micro-hydro in the UK and developed nations and that there are abundant existing dams into which our technologies can be installed without having to build new ones. Hallidays are working to patent this system urgently as we are currently going through planning permission for the first prototype.
One of our preferred solutions for low-head hydropower installations, is the Archimedean screw turbine. It has numerous versatile benefits for these applications however principally its fish friendly nature draws us to it.
The steel screw turbine has been used in hydropower since 1990 and only really coming into wide scale deployment in the early 2000’s. The basis for this technology has simply been the reverse of an Archimedes screw pump. There have been very few innovative changes made to the screw for its new use in hydropower.
Steel screw turbines have significant manufacturing and transportation costs due to the heavy and large components. A new lightweight, durable design of turbine would greatly reduce these costs and also allow easy transportation to remote locations, both nationally and internationally.
Extensive prototype development and testing has been carried out to determine the optimal high-tech moulded plastic to be used. Durability, weight and ease of installation are the key driving parameters behind the innovation. This new turbine is now going through patenting and rigorous testing.
In addition to this, our analysts and programmers carry out exciting work on the following:
