About

BioPower Systems is a renewable energy technology company based in Sydney Australia. We are developing systems for both wave and tidal power conversion. The company is currently working on ocean-based pilot projects and follow-on market opportunities for its products and services.

Technology

BioWave

The wave power system, bioWAVE™, is based on the swaying motion of sea plants in the presence of ocean waves.

The hydrodynamic interaction of the buoyant blades with the oscillating flow field is designed for maximum energy absorption. In extreme wave conditions the bioWAVE™ automatically ceases operating and assumes a safe position lying flat against the seabed. This eliminates exposure to extreme forces, allowing for lighter designs and substantial cost savings.

Systems are being developed for 250kW, 500kW, 1000kW capacities to match conditions in various locations.

BioStream

The tidal power conversion system, bioSTREAM™, is based on the highly efficient propulsion of Thunniform mode swimming species, such as shark, tuna, and mackerel.

The bioSTREAM™ mimics the shape and motion characteristics of these species but is a fixed device in a moving stream. In this configuration the propulsion mechanism is reversed and the energy in the passing flow is used to drive the device motion against the resisting torque of an electrical generator.

Due to the single point of rotation, this device can align with the flow in any direction, and can assume a streamlined configuration to avoid excess loading in extreme conditions. Systems are being developed for 250kW, 500kW, and 1000kW capacities to match conditions in various locations.

BioBase

BioPower Systems has developed a novel singular mounting system called bioBASE™. This system is modeled on the seabed holdfast mechanism used by large sea plants, such as the giant kelp. In such systems, the vertical and lateral loads that are translated to the seabed by the main shaft are re-distributed into many smaller elements that engage with the bottom strata. This mechanism serves to distribute the forces and alleviate excess loads.

The bioBASE™ utilises rockbolting technology for the multiple ‘roots’ of the system, and does not require large specialised vessels or drill rigs due to the small gauge of each bolt.

Once the bioBASE™ has been installed, the surmounting device (either the bioWAVE™ or the bioSTREAM™) is easily attached and secured with the assistance of a single surface vessel. Other applications of the bioBASE™ technology are offshore wind turbines and deepwater foundations.

About
The head office, laboratories and manufacturing operations of Dyesol are in Queanbeyan, New South Wales, Australia. Dyesol is a public company which listed on the Australian Stock Exchange on 31st August 2005. The ASX code for Dyesol is DYE.

The Dyesol team has been developing its blocking patent suite for more than 10 years. Dyesol benefits from investment of almost 300 person-years in DSC technology by the Australian team. Throughout this time, the Australian team has benefited from a close connection to EPFL in Switzerland, where the original DSC invention was made.

Universities in Japan, Korea, USA, Thailand, Taiwan, as well as EPFL in Switzerland have all purchased DSC materials in the Dyesol range, (e.g. dye, titania paste) for DSC projects (PV and direct hydrogen production).

Dyesol is proud to supply materials to more than 25 countries throughout the world via its on line purchasing web-site.

  • The Dyesol team established the worlds first prototype manufacturing facility for Dye Solar Cells

  • Dyesol supplies equipment, materials and components for Dye Solar Cell Technology

  • Dyesol is supported by a team of world leading experts and offers consulting services

  • Dyesol supplies a range of turnkey solutions, from laboratory and research to prototype manufacturing.

  • Dyesol participates in both public and private funded Research & Development programs

  • Dyesol is seeking suitable parties to licence its Technology

Technology

Dyesol’s technology is based on Dye Solar Cell (DSC), which has been identified in the Japanese and EU Photovoltaic Roadmaps as the emerging solar technology, it has also been called the most promising advance in solar cell technology since the invention of the silicon cell.

DSC technology can best be described as ‘artificial photosynthesis’ using an electrolyte, a layer of titania (a pigment used in white paints and tooth paste) and ruthenium dye sandwiched between glass. Light striking the dye excites electrons which are absorbed by the titania to become an electric current many times stronger than that found in natural photosynthesis in plants.

 

Compared to conventional silicon based photovoltaic technology, Dyesol’s technology has lower cost and embodied energy in manufacture, it produces electricity more efficiently even in low light conditions and can be directly incorporated into buildings by replacing conventional glass panels rather than taking up roof or extra land area.

 

Advantages include not necessitating the use of high-priced raw materials, a manufacturing process that does not produce toxic emissions, and the potential for rapid efficiency enhancement.

 

Dyesol enjoys a lead position in developing and commercialising DSC technology.

 

Product

The building blocks for Dyesol’s products are Dye Solar Cells interconnected and integrated into modules (tiles). The tiles are ochre, with introduction shortly of other colors such as grey, green and blue. These tiles can be connected in series or parallel to produce Solar Panels.

In Dyesol’s registered design for building integratable Solar Panels, the panels are constructed in a laminated structure, with the tiles connected and sandwiched between two panes of glass and fully encapsulated in the UV resistant transparent laminating polymer (Solar Wall Panels). Dyesol’s Solar Wall Panels are designed for exposed mounting and to be isostructural to existing fascia – replacing, not duplicating, the existing facade. Electrical interface can be typically via a short DC bus to a local area network for distribution or inversion to AC.
