3D-printed ceria is a game-changer to increase solar fuel efficiency

3D-printing the perfect ceria structure enables incoming heat from a solar field of mirrors to spread evenly throughout a solar reactor.(How solar fuels are made: thermochemistry) IMAGE@Sebastian Sas Brunser 3D-printed ceria was one of the many brilliant ideas presented by international solar researchers at this year’s SolarPACES Conference in Sydney. In solar reactors for making …

Methane pyrolysis with liquid metals in a bubble column reactor to generate green hydrogen and carbon

Methane Pyrolysis in a Liquid Metal Bubble Column Reactor Using a bubble column reactor at Karlsruher Institut für Technologie, the Liquid Metal Laboratory team is working on producing hydrogen from methane, the cheapest method, but without CO2 emissions – the problem with the cheapest method. The main product, besides hydrogen, is carbon, which, like green …

A New Hope For Concentrated Solar Power

Concentrating solar power systems are getting an energy efficiency makeover and a new job: producing solar fuels. The solar fuels field is beginning to gather steam, and that could spell good news for fans of concentrating solar power. Compared to conventional solar panels, concentrating systems are sprawling, expensive, and complicated affairs. However, they can deliver …

Heliostat concentration boosted by shape-shifting glass

Heliostats get a concentration boost by bending and twisting the mirror with a mechanical frame By manipulating the shape of heliostats in real time, the optical efficiency of solar fields for tower CSP can be significantly increased, according to a paper presented at the New Mexico SolarPACES Conference: Heliostat with Automatic Shape Adjustment for High …

Published at Energy Conversion and Management – Thermodynamic and economic analysis of a multi-energy complementary distributed CCHP system coupled with solar thermochemistry and active energy storage regulation process

Abstract: The combination of distributed energy systems (DES) and solar energy is considered a vital measure to save the usage of fossil energy. A new distributed combined cooling, heating and power (CCHP) system integrated with solar thermochemistry (STC) and energy storage (ES) units is proposed. The methane steam reforming (MSR) reaction is driven by solar …

Solar hydrogen testing begins at CSIRO conference tour site

Solar hydrogen testing has begun at the CSIRO test site in Australia. The concentrated solar falling particle receiver seen here reaches the high temperatures used for solar thermochemistry. SolarPACES Conference 2023 will include a site tour here. IMAGE@Wil Gardner, CSIRO Tests are underway on a cutting edge renewable hydrogen technology that is being backed by …

Published at Chemical Engineering Journal – Green ammonia to Hydrogen: Reduction and oxidation catalytic processes

Ammonia. Computer model of a molecule of ammonia(NH3). Atoms are represented as spheres and are colour coded: nitrogen (blue) and hydrogen (white). Ammonia is a pungent-smelling colourless gas. It occurs naturally in gases from some geothermal springs.  Abstract: Green ammonia, produced at ambient conditions, has received significant attention as a carrier of hydrogen for energy …

Australia’s Vast CSP to include green methanol demo for shipping

Maersk has already ordered 19 vessels with dual-fuel engines able to operate on green methanol. Why Vast plans to include methanol production in their CSP project Methanol is used to make many chemicals, but what makes producing green methanol most interesting for the future is that the shipping industry, finally having to deal with climate …

Published at Energy Conversion and Management – Structural stabilization of granular Ca(OH)2 by coating with nanostructured additives for thermochemical cycling in a fixed reaction bed

Abstract: Thermochemical energy storage systems have a high potential to support a future energy supply based on renewables by providing comparably high storage capacities and option for long-term, cold and loss free storage, that allows a flexible utilization in several application areas. Due to its cost efficiency and abundance the reaction system Ca(OH)2/CaO is currently …
