European Scientists Look To Globalize Solar Energy Grid
A global solar energy grid? That seems a bit farfetched, or is it? Based on current nanotechnology and expected improvements and innovations, European scientists are seriously considering that very possibility. This confidence and forward-thinking, which found expression at the recent European Science Foundation conference, stems from the promise of dye-sensitized solar cells (DSCs) and biomimetics.
DSCs commonly use a natural or synthetic dye and titanium dioxide to capture and convert solar energy into usable electricity. These third-generation solar cells are biomimetic because they essentially mimic the natural process of photosynthesis. Despite recent breakthroughs in efficiency and longevity, DSCs are still well behind silicon-based and thin-film solar cells, but their potential is undeniable. So undeniable that many scientists are predicting their inevitable rise and dominance of the renewable energy market.
Nanotechnologies offer much cheaper solar cells that can easily be imprinted onto flexible sheets and distributed affordably around the world. Now, if we could spread cost-effective solar power across the globe, then why not connect the entire globe on one solar energy grid? This is the mammoth idea that some European scientists are putting forth--exemplifying their commitment to solar energy as the dominant force in replacing fossil fuel energy.
A global solar network is certainly no simple task. The United States is already having trouble transmitting its renewable energy between its own borders. Nonetheless, these solar enthusiasts are confident. The sun is always shining somewhere on the Earth, so solve storage and nighttime-availability issues for solar energy by connecting the world via one electric grid and simply move solar energy to wherever its needed from wherever it is currently abundant.
Obviously this will not be done tomorrow, but these scientists can now see the open road that they think could easily lead us there. Furthermore, biomimetics offer benefits beyond just solar power. Mimicking photosynthetic processes in plants can be used to make hydrogen and alcohol for fuel, create hydrocarbons for energy (recycling them from the air and thus not increase carbon levels in the atmosphere), and revolutionize battery storage for electric automobiles.
