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 [...]
Solar fuels like hydrogen have the potential to be next generation energy carriers for a carbon-constrained world. Green hydrogen and other solar fuels could replace fossil fuels used for most transport; replacing heavy fuel oil used by container ships, the jet fuel used to fly planes, and the diesel and [...]
As detailed in the paper co-authored by IHI Corporation researcher Satoshi Seo (Production of C2-olefins and Hydrogen from Methane Pyrolysis with Concentrated Solar Energy) presented at the SolarPACES Conference in South Korea; this novel two-step process produces hydrogen and carbon materials without producing carbon dioxide, and avoids several technological problems [...]
A preliminary study of the average cost of a novel process for producing solar hydrogen in several locations in Australia finds it could come close to the US DOE renewable hydrogen target of $3 per kilogram. The way that hydrogen is reformed from natural gas is a well-established, low-cost process. [...]
The large-scale and renewable production of hydrogen could soon be possible thanks to a new photoelectrochemical device that is driven by concentrated sunlight. When scaled-up, the technology could revolutionize how hydrogen is produced and make the gas a viable alternative to fossil fuels. Saurabh Tembhurne (left), Sophia Haussener (centre) and [...]
Not too long ago, the mention of hydrogen, or concentrating solar power, or both at the same time, would be met by a roll of the eye from alternative energy insiders. Hydrogen is an abundant and clean-burning fuel, but the primary source of hydrogen is natural gas. Concentrating solar [...]
Thermochemical solar leverages heat from concentrated solar power (CSP) for chemical reactions. Research into thermochemical solar reactors to split water to hydrogen is a priority in top national laboratories internationally. (See SolarPACES Research Task II: Solar Chemistry Research). What part will thermal solar play in a future hydrogen economy? To [...]
On 28 November 2017, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), together with international project partners, presented what is currently the largest solar-chemical installation for the production of hydrogen. In the HYDROSOL_Plant project, scientists and companies have jointly further developed the process of direct hydrogen production using [...]
For years now, scientists from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have conducted research at the Plataforma Solar de Almería (PSA) in the south of Spain, which is operated by partner organisation CIEMAT (Centre for Energy, Environment and Technology). At this location scientists are [...]
