hydrogen

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.

A 2 MW solar park in Wallonia, Belgium, will rely 50 kW of hydrogen-producing solar modules developed by Solhyd, a spin-off from KU Lueven. The installation will be the first demonstration of Solhyd’s technology at a commercially-relevant scale.

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.

The Swiss startup presented the battery plus hydrogen idea to a Symposium this week.

The projects, equivalent to 1.88 GW of electrolyzer capacity, were withdrawn after choosing not to continue with the agreement procedure or for being unable to provide a signed completion guarantee. As a result, ten hydrogen projects representing 774 MW in capacity from the reserve list have been invited to prepare grant agreements.

Scientists at Italy’s University of Cagliari explored the integration of a water electrolyzer with a floating PV-pumped hydro energy storage system. They found that under high curtailment conditions, hydrogen production helped to stabilize system efficiency and lower the levelized cost of electricity when compared to a system without the electrolyzer.

Global hydrogen investment has topped $110 billion, up $35 billion from last year, with total committed capacity exceeding 6 million tons (metric tons) per year (mtpa), says the Hydrogen Council.
