StratoSolar PV provides a complete, lower cost replacement for fossil fuels
- StratoSolar PV power plants provide low-cost, sustainable, zero-carbon electricity from a combination of solar energy and gravity energy storage.
- The power plants are a complete, lower cost replacement for base-load and dispatchable electricity generation from coal and natural gas.
- They need no additional backup generation, electricity storage or electricity grid changes .
- They offer enormous environmental and energy security benefits over fossil fuels.
- They can scale from small MW scale plants for islands, remote locations and/or developing countries to very large multi-GigaWatt scale plants positioned near large urban areas.
- They can eventually meet the complete world energy demand using only clean, safe, sustainable solar energy without stressing available land or natural resources.
StratoSolar solves all of the problems of current Solar PV electricity generation
- Cost: Despite dramatic price reductions in recent years, today's Solar PV electricity is still expensive and investors need the support of substantial subsidies to make PV plants affordable today and for the foreseeable future. StratoSolar's 3X higher utilization factor reduces costs to less than fossil fuel generation, solving the cost problem.
- Intermittency: Clouds and bad weather can block sunlight for days to weeks. For PV on the ground, coping with this random intermittency requires either expensive backup fossil fuel generation capacity or excess clean energy generation capacity combined with excess long distance transmission capacity. StratoSolar is above clouds and weather and provides completely predictable generation during daylight hours, directly solving the intermittency problem.
- Night Time: There is no electricity storage solution that can provide cost competitive night time electricity today. StratoSolar includes low cost gravity energy storage, enabled by the high altitude of StratoSolar platforms, solving the night time generation problem.
- Geography: Solar energy is abundant in deserts where there are no people and scarce near urban areas where most people are located. Exploiting deserts means using expensive long distance electricity transmission. StratoSolar exploits abundant solar energy near urban areas, eliminating the need for additional long distance transmission and solves the geographic location problem.
