Synhelion's solar receiver achieves a temperature of 1,500°C and higher. That's unprecedented. Even the Gen3 particle-based solar receiver being pilot-scale tested now at Sandia - and the DLR CentRec receiver licensed to Heliogen - operate at the (relatively!) lower...
Abstract: This study analyzes the technical performance, costs and life-cycle greenhouse gas (GHG) emissions of the production of various fuels using air-captured water and CO2, and concentrated solar energy as the source of high-temperature process heat. The solar...
Press Release: Aug 3 2023 Synhelion and Cemex announced today a significant milestone in their joint effort to develop fully solar-driven cement production: the scaling of their technology to industrially-viable levels. This includes the continuous production of...
Tour the pilot-scale sodium receiver and falling curtain particle receiver in Australia During the 29th SolarPACES Conference, a day trip from Sydney will take you on a Technical Tour of the CSIRO National Solar Energy Centre at Newcastle, where the working of two...
Abstract: Over the past few decades, inorganic nitride materials have grown in importance in part due to their potential as catalysts for the synthesis of NH3, a key ingredient in fertilizer and precursor to industrial chemicals. Of particular interest are the ternary...
Green ammonia could be made sustainably using solar thermochemistry instead of the way it is made today in the fossil-fueled Haber-Bosch process, which taps fossil energy for the thermochemistry and the heat and the high pressure it requires, while emitting almost...
Solar hydrogen is a component of the thermochemical solar fuels that Synhelion is developing commercially, such as aviation fuel The solar thermal green hydrogen technology beginning to be commercialized by Synhelion has now received a nod from the US DOE with funding...
Xavier Lara’s consultancy AELIUS Energies SLU to champion green ammonia for shipping before an audience of major shipbuilders in Qingdao China
Solar fuels are made using thermochemistry driven by direct heat from the sun In this process, solar thermal energy provides the heat for thermochemical reactions to produce new compounds such as green hydrogen or sustainable aviation fuel. Highly concentrated solar...
Press Release: Heliogen Collaboration to decarbonize America’s “First Hydrogen City” through Heliogen’s patented breakthrough CST technology PASADENA, Calif. & LANCASTER, Calif. (June 6, 2023) —Heliogen, Inc. (“Heliogen”) (NYSE: HLGN), a leading provider of...
Solar even under grey skies 365 days a year: Typically, simplicity equals low costs. But the creators of a multi-technology thermochemical energy storage system for Gen3 concentrating solar power (CSP) claim that their complex design would bring costs down by enabling...
Abstract: La and Yb were incorporated as co-doping elements into Zr-doped ceria to investigate the influence of doping ions by means of ionic radius and valence on the ceria crystal lattice and potentially on thermodynamic and kinetic properties relevant to...
Abstract: Solar-driven two-step thermochemical cycling is a promising means to convert solar energy into storable and transportable chemical fuel, in which hydrogen or carbon monoxide is generated by continuous reduction and oxidation reactions. However, the high...
A new solar-radiation-concentrating device produces green hydrogen at a rate of more than 2 kilowatts while maintaining efficiencies above 20%. The pilot-scale device, which is already operational under real sunlight conditions, also produces usable heat and oxygen,...
Abstract: Solar thermochemical hydrogen (STCH) generation is a promising approach for eco-friendly H2 production, but conventional STCH redox compounds cannot easily achieve desirable thermodynamic and kinetic properties and phase stability simultaneously due to a...
Abstract: This article discusses several routes available to produce hydrogen fuel, with a special focus on solar thermochemical cycles for Water Splitting (WS). Solar thermochemical WS cycles are a potential technology to produce green hydrogen and CO in the future...
Abstract: Drop-in fuels produced using solar energy can provide a viable pathway towards sustainable transportation, especially for the long-haul aviation sector which is strongly dependent on jet fuel. This study reports on the experimental testing of a solar reactor...
Adding nickel to ceria can yield solar syngas at lower temperatures - at just 700°C Solar thermochemistry researchers at the University of Florida and Synhelion tried a new way to generate syngas, the precursor to hydrocarbon fuels like jet fuel or diesel. Solar...
Abstract: The solar splitting of H2O and CO2 via a thermochemical redox cycle offers a viable pathway for producing sustainable drop-in fuels for the transportation sectors. The key performance metric is its solar-to-fuel energy efficiency, which is strongly dependent...
Goal: ensure the quartz window never exceeds 300°C, despite solar receiver temperatures above 1500°C – keeping thermal efficiency over 50%
