New York (CNN Business) A secretive startup backed by Bill Gates has achieved a solar breakthrough aimed at saving the planet. Heliogen, backed by Bill Gates, has achieved a breakthrough that could allow cement makers to transition away from fossil fuels. Heliogen said it would solve that issue by relying on storage systems that can hold the solar energy for rainy days. Heliogen's biggest challenge will be convincing industrial companies using fossil fuels to make the investment required to switch over. Its biggest selling point is the fact that, unlike fossil fuels like coal, oil and natural gas, sunlight is free.
