Sisyphus Energy, Inc.
ESSENTIALS OF ENERGY STORAGE
Hawaii is the most fossil fuel dependent state in the United States. But HI has set 2045 deadline for 100% renewable electricity sourcing. Unfortunately, two of the principal renewable energy sources, wind and solar are intermittent, producing energy only when the wind blows or the sun shines. Even with substantial increases in renewable electricity production, there will be periods without enough available power. Some sort of bulk energy storage will be required. For various reasons, only the Sisyphus system of energy storage will be suitable for Hawaii’s use. Fortunately, the cost of the Sisyphus system in terms of levelized cost of energy is lower than all other renewable options.
