  5. Machine Hall 15 – Commercial activities

    This Machine Hall is made available for the potential it offers in supporting the exploitation of related commercial opportunities.
    A prime intention is to support opportunities that could provide lasting long-term employment in South Wales. Two are worth considering immediately.
    1. An electricity-generation sub-station - Operated by Tata Power
      An overview shows the close proximity of large industrial centres of electricity users - Swansea, Cardiff, Newport, Gloucester and Bristol - makes power distribution from an Aberthaw Tidal Power Station very simple.
      In particular heavy industry, such as steel production in Port Talbot and Llanwern, would benefit by the electricity produced by the barrage at a strike price of a little over £30 per megawatt hour. This would confer a significant advantage on UK industry over worldwide competition.
      Tata Steel currently operate steel making plant in Port Talbot and Newport (Llanwern) that will fail financially unless a source of low-cost electricity is found. 'Supported' high cost electricity is not a way forward. It has to be ‘real’ and cheap.
      A particular Tata investment in a segment of the Aberthaw Tidal Power Station, such as Machine Hall 15, could be to the advantage of all parties. The introduction of dedicated power lines delivering electricity to the Port Talbot plant from one or more designated water-turbine/generator units owned and run by Tata staff would be profitable and secure.
      This would significantly help make the Tata steel making financially sustainable and perhaps give this sector of UK steel a competitive advantage.
      Tata Power in Mumbai, India have 8,000 megawatts of generating plant and are the largest integrated power supplier in that country. It has the technical and commercial ability, knowhow and balance sheet to make an investment in Machine Hall 15.
    2. Industrial storage-battery development and testing
      Machine Hall 15 could provide a testing facility for storage-batteries up to 480MW. In addition to meeting the growing market need for facilities in which to develop industrial sized storage batteries it could provide a base for Sodium-ion battery development in the UK. Professor Zhenan Boa, of Stanford University California, has developed a Sodium-ion based material with a comparable energy density to conventional Lithium-ion.
      A sodium-ion battery ‘costing less than 80% of a Lithium-ion battery with the same power density’ is a prize worth entering the R&D race for.
      The Aberthaw barrage provides a large, security-monitored, working-environment suitable for commercially sensitive testing.
      UK is already in this scientific field and may well have an interest.
      The close proximity of Aberthaw to Cardiff airport could favourably influence investment from the USA in the UK and provide worthwhile opportunities for the workforce in South Wales.
