Long Duration Thermal Energy Storage to Prevent Wasting Solar and Wind Energy

The Malta energy storage system takes electricity, converts and stores that electricity as heat, and then converts it back to electricity to be redistributed on the electric grid. In charge mode, the system operates as a heat pump, storing electricity as heat in molten salt. In discharge mode, the system operates as a heat engine, …

President Xi Goal is a Carbon Neutral China by 2060

China’s President Xi has committed to make China Carbon neutral by 2060. China’s top university, Tsinghua, has published an energy plan to reach that goal. The plan would be increase nuclear energy by nearly 5 times from today’s level and to eliminate coal for electricity by 2050. China would depend upon solar, wind and nuclear …

Global CO2 Emissions Did Not Increase in 2019

Global emissions were unchanged at 33 gigatonnes in 2019 even as the world GDP grew by 2.9%. Increased wind, solar power, natural gas power and higher nuclear power output in developed countries offset increased emissions in emerging countries. * coal CO2 emission declined by about 200 million tonnes (Mt). This was -1.3%. * advanced economies …

Germany Solar and Wind is Triple the Cost of France’s Nuclear and Will Last Half as Long

France’s nuclear energy spending was 60% of what Germany spent on renewables. France gets about 400 Terawatt hour per year from nuclear but Germany gets 226 Terawatt-hours each year. 45 Terawatt-hours of Germany’s renewable power comes from burning biomass which generates air pollution. Germany’s solar farms will have to be rebuilt every 15-25 years. The …

France’s Nuclear Buildout Was More Cost Effective Than 2018-2022 Solar and Wind

France built up nuclear power in 15 years using inflation-adjusted $330 billion to generated over 400 TWh of electricity for many decades. Global solar power only passed 400 TWh in 2017. The first 1000 TWh of wind and solar required approximately $2.3 trillion of capital expenditure to deploy. About three times more was spent on …
