THE ENVIRONMENTAL IMPACT
Much of Australia’s climate change debate is focused on ‘generation side management’ - ways to reduce emissions from electricity generation such as clean coal, solar, wind and geothermal sources.
However, the first approach usually advocated in addressing climate change is ‘demand side management’ - reducing current energy usage. This is typically described as the ‘cheapest megawatt hour is the one we don’t use’ or the ‘cleanest power station’ is the one we don’t build.
One of the key values of the BluGlass technology is that it could become a significant force in the reduction of greenhouse gases in Australia and the world. At BluGlass we believe that both sides of the energy debate require action and attention in order to sustain both economic growth and environmental amenity.
Our unique RPCVD technology aims to help reduce the amount of electricity used in lighting significantly (demand side management) as well as bringing to market large scale, cost effective renewable energy from the sun (generation side management).
LEDs for the environment
•Our unique process has the potential to improve LED performance and cost of manufacture while at the same time but also uses a more environmentally benign process free of the highly toxic ammonia
- Globally it is estimated that LEDs could save 30% of the electricity used in general lighting
- Our Sydney based pilot plant is designed as an environmentally safe facility capable of manufacturing semiconductor materials and meeting all of our R&D goals
- LEDs do not contain the extremely harmful substance, mercury, found in CFLs and are safe to dispose of at the end of their long life
- Once LEDs replace inefficient current technologies such as incandescent bulbs and environmentally harmful technologies such as CFLs, much less electricity will be required to light our lives. Less energy consumption directly equates to less greenhouse gas production in our atmosphere
- It is estimated that if LEDs were installed for lighting around the globe, it would alleviate the need for 133 nuclear power stations
CPV for the environment
- Our unique process has the potential to bring high efficiency InGaN solar cells to commercial reality due to its low temperature manufacturing advantages
- Concentrated photovoltaics (CPV) promises large scale, high efficiency renewable energy from the sun that addresses many of the concerns that have limited the success of solar energy in the past
- CPV uses less semiconductor material than conventional solar technologies. CPV uses mirror or lens technology to concentrate a large area of sunlight onto a smaller area of material to concrentrate the sunlight up to several hundred times
- CPV is less land intensive than other solar technologies and is suitable for marginal land applications where direct nominal irradiance (DNI) is high or extreme
- CPV does not require water cooling during energy generation
- CPV can be installed closer to end use areas than other fossil fuel and renewable energy generation techniques and reduce infrastructure requirement and costs
- InGaN solar cells offer additional advantages of durability and long life and can withstand extreme radiation suitable for space applications to also increase satellite lifetime
- All of these advantages can lead to dramatically reduced energy generation costs and allow significantly more sustainable energy generation
