green hydrogen

Scientists have simulated a residential building based on a real double-story house in the United Kingdom, combining rooftop agrivoltaics with onsite hydrogen production. Electricity generated by the solar system is used to produce hydrogen, which is then supplied to a hydrogen vehicle and insulated gasochromic smart windows.

Scientists have simulated a solar-powered hydrogen production system comprising 32,050 photovoltaic panels, a pumping system, a seawater reverse-osmosis desalination unit, an electrolyzer, and a hydrogen storage tank. Operation of the system in Oman could potentially yield a levelized cost of electricity of $0.05/kWh and a levelized cost of hydrogen of $9.5/kg.

Researchers at MIT World Peace University (MIT-WPU) in India have developed a liquid organic hydrogen carrier (LOHC) system that enables hydrogen to be transported in a stable liquid form. The system is non-flammable, non-explosive, and can be handled at normal temperatures and pressures.

Spanish renewables specialist Táctica Industrial says its off-grid photovoltaic system produces green hydrogen at about €400 ($470)/kW using modular alkaline electrolysis without inverters or grid connection.

The Japanese conglomerate has deployed its Panasonic HX hydrogen solution at its facility in Munich. The system uses an AI-based energy management system that reportedly makes battery storage unnecessary.

NTPC has developed a standalone solar microgrid system that uses hydrogen as the storage medium to deliver 200 kW of round-the-clock power throughout the year. Designed to replace diesel gensets at off-grid Army locations, the system provides a reliable and sustainable power supply even in harsh winter conditions, where temperatures can drop to –40 C at an altitude of 4,500 meters.

Scientists in China have proposed a novel scheduling framework for microgrids based on hybrid PV and a small modular nuclear reactors. The framework uses multi-objective distributionally robust optimization with a real-time reinforcement learning mechanism and is reportedly able to reduce operational costs by 18.7%.

A team of researchers in Canada has developed the Jericho Open Resistive Data Logger—an open-access photovoltaic (PV) monitoring platform that integrates data acquisition and processing hardware, a software framework, and a comprehensive sensor array. Designed primarily for agrivoltaic applications, the system has a total estimated cost of around $2,000.

German industrial group Bosch says the Bamberg facility complies with European Union renewable hydrogen rules and will produce over one ton of green hydrogen daily.

Chile’s Colbún has started operations at a solar-powered green hydrogen unit at its Nehuenco thermoelectric complex, replacing fossil-based hydrogen used in generator cooling.
