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, and its developers at the École polytechnique fédérale de Lausanne (EPFL) in Switzerland [...]
Published in the January Issue of Energy Conversion and Management Computational fluid dynamics study of hydrogen production using concentrated solar radiation as a heat source Abstract The purpose of this paper is to study the performance of the steam methane reformer (SMR) using solar energy as a heat source using [...]
The efficient integration of renewable energy with hydrogen storage is an important means for China to achieve carbon neutrality. Concentrated solar power (CSP) is an emerging technology for solar energy utilization that combines the advantages of power generation and energy storage. However, CSP has not been fully exploited because of [...]
Perovskite materials may hold the potential to play an important role in a process to produce hydrogen in a renewable manner, according to an analysis from scientists at the National Renewable Energy Laboratory (NREL). Hydrogen has emerged as an important carrier to store energy generated by renewable resources, as a substitute for [...]
Oil and gas giant Woodside Petroleum has agreed to help fund the construction of a 5MWe concentrated solar technology demonstration plant in California’s Mojave Desert, and has struck a deal that could see it use the technology for green hydrogen and other uses in Australia and around the world. The [...]
Heliogen, a leading provider of AI-enabled concentrated solar power, today announced that the United States Bureau of Land Management has awarded the Company the exclusive right to lease land in the Brenda Solar Energy Zone (SEZ). Heliogen intends to develop a green hydrogen facility on the Brenda site, capable of [...]
In an institutional event, the mayor of Seville, Juan Espadas, and the delegate of the Free Zone, Alfredo Sánchez Monteseirín, visited the plant, located in Free Zone of Seville (Spain). Once passed the start-up phase, the plant will prepare to be transferred to its destination in The Netherlands. Grasshopper is [...]
Two companies, Bloom Energy and Heliogen, have announced that they have successfully used concentrated solar power (CSP) for green hydrogen fuel production at a recent demonstration that took place in California. Heliogen was the supplier of the CSP technology that was used for powering the demonstration. Bloom energy used its [...]
IEA report calls for the development of national hydrogen strategies and roadmaps, new incentives for low-carbon hydrogen, and new certification requirements alongside increased research and infrastructure spending. Direct heat solar thermochemistry using CST is a promising route to lower cost of green hydrogen production IMAGE@Heliogen Global electrolyzer capacity for producing [...]
Heliogen and Bloom Energy (NYSE: BE) today announced plans to produce green hydrogen using only concentrated solar power and water, further accelerating the world’s progress toward a zero-carbon future. By combining near 24/7 carbon-free power and steam, generated by Heliogen’s Sunlight Refinery solar power generation system, with Bloom Energy’s highly [...]
The ETH spin-off Synhelion is working on commercializing its very high-temperature solar thermochemical fuels (like jet fuel and hydrogen) and has already formed partnerships with several larger firms making cement or aviation fuel to advance step by step towards its goal of 100% carbon neutral fuels by 2030. DLR [...]
A perovskite may be more cost-effective than ceria for solar-driven thermochemical hydrogen production, a new paper suggests. One perovskite formulation that works at a slightly lower temperature than ceria is explored by Xin Qian in the paper Outstanding Properties and Performance of CaTi0.5Mn0.5O3–d for Solar-Driven Thermochemical Hydrogen Production in research funded [...]
Integrated Hydrogen Sensor/Separation Module Provides Long-Term Boosts in Efficiency and Revenue in Solar Power Plants. NREL and Acciona Solar Power Develop Technology To Reverse Costly Effects of Hydrogen Buildup in Concentrating Solar Power Receiver Fields. Since the mid-'80s, concentrating solar power (CSP) plants have generated clean energy to power [...]
