Solar Can Make Carbon Neutral Aircraft Fuel from CO2 + H2O

In the future we can mix solar heat + CO2 + H2O to make a carbon neutral kerosene (aircraft jet fuel) that will make flying climate friendly. Making thermochemical solar fuel is renewable, because sunlight, carbon dioxide and water is essentially unlimited. So solar from deserts could fuel aircraft flights for centuries while not adding […]

Q & A: DLR’s Christian Sattler on the Role of Solar Thermochemistry in Green Hydrogen Production

What part will solar thermochemistry play in building a future hydrogen economy? For an overview, we checked with a top solar hydrogen expert, Christian Sattler, who holds 18 patents and has authored 158 peer-reviewed papers. Sattler heads the Department of Solar Chemical Engineering at the Institute of Solar Research at Deutsches Zentrum für Luft- und […]

How Solar Peaker Plants Could Replace Gas Peakers

Solar can be designed to run only after dark at a competitive price with a current natural gas peaker plant. Concentrated Solar Power (CSP) can be a night-only dispatchable (D-CSP) plant; with its entire solar energy absorbed by day to be delivered after dark to cover the evening peak load on the grid, according to a study funded by the US Department of Energy (DOE). Read More …

What is the Difference Between the Two Kinds of Solar: CSP and PV?

Read here about exactly how Concentrated Solar Power (CSP) works producing electricity from a power block thermally the way a conventional power plant does – except that sunlight is the fuel. PV (Photovoltaic) solar works in a completely different way from CSP All electricity is basically just electrons moving down a wire. Michael Faraday discovered in 1831 […]

LCOE is an Outdated Metric for a Solar Grid

The electric grid has changed since 1917. So should our way to evaluate what’s on it. For nearly all of its first century, all electricity was baseload.To compare costs between these various forms of baseload generation, a common metric, LCOE (levelized cost of electricity) made sense. But that has changed, because the grid has changed. […]
