Belgian mechanical engineering group John Cockerill wants to set up its electrolyzer gigafactory for the production of green hydrogen in northeastern France. Galp Energia plans to install a 100-megawatt electrolyzer to power its refinery in Sines, Portugal, with green hydrogen, by 2025.
Long distance, point-to-point transport of green hydrogen for industrial use can harness the cheap solar electricity available in some parts of the world but distributing the energy-storage gas to individual refueling stations, for vehicle fuel cell use, will likely have to depend on production nearby.
An international research team has designed a residential solar-plus-storage system based on gravity. The system was built with a solar power generator, a bulk booster charge controller, an inverter, a solenoid device, a deep cycle battery, a pulley block, a geared motor, a microcontroller, and wire ropes. Its creators said the system is ideal for regions with high solar radiation. They found that, due to its high electrical requirements, the system needs to rely on high-power solar modules with an output of over 500 W.
A new project offers a design and validation framework for renewables-based microgrid configurations that deliver electric vehicle fast charging, energy security, and value-added grid services.
The Scottish government wants to deploy renewable-powered heat pumps on at least 1 million homes and 50,000 non-domestic buildings by the end of this decade. For this purpose, it has created an advisory group and is now seeking to gather all potential stakeholders.
According to a new study from LUT University, domestic water heating costs may be reduced by combining rooftop PV with geothermal heat pumps. Scientists developed a control method to minimize these costs by taking advantage of cheap spot market electricity and maximized PV power generation, as well as considering heat demand, PV generation forecasts, and heat pump efficiency.
A solar array planned in the Tetereane district of Cuamba has been described by its developer as the nation’s first independent power project to feature utility scale storage.
The system is based on a power-to-gas hydrogen technology and is intended to enable one and two-family homes to have an independent power supply throughout the year.
Furthermore, Swiss energy company Axpo and Swedish-Swiss electrical equipment giant ABB committed to combining their technologies and skills for several projects related to green hydrogen in Italy and Germany’s gas transmission system operators Gascade and Ontras announced a plan to set up a platform for the hydrogen industry in eastern Germany, with an initial grid to cover 475 kilometers of pipelines.
