French startup Wind my Roof has developed a new wind power system equipped with two rooftop PV modules. It is currently testing a prototype in Paris.

The new provisions define clearly what hybrid power plants are and what kind of grid tariffs they should pay. The regulation may be particularly favorable for hybrid wind-solar plants, especially in North-Eastern Brazil, where the grid is not strong enough to support further renewable energy development.

Tested in an off-grid location in India, the proposed approach includes the use of thermal storage from PV modules’ excess heat for space and water heating. The optimum configuration for the system was given by the combination of a 224 kW PV system equipped with a phase change material, a 206 kW wind turbine, a 420 kW biogas generator, a 633 Ah battery, and a 170 kW converter.

A couple of years ago, the Australian state of Queensland became a beacon to advisory Energy Estate and international renewables developer RES Group. The Moah Creek Renewable Energy Project, the first stage of their gigawatt-scale plan, is now about to be introduced to the community.

According to a new study from a German-Swedish research group, conventional incentives such as renewable portfolio standards, feed-in tariffs or feed-in premium payments may likely lead to a price cannibalisation scenario for wind and solar. CO2 pricing, instead, is considered an efficient tool to maintain their market value high enough to ensure new investments. However, a total system cost approach, rather than an LCOE perspective, is needed to understand the strong dependence of market value on policy choice.

According to a new study from the LUT University, hybrid wind-solar plants offer the ideal profile to reduce the costs of green ammonia. Although natural gas will be able to provide lower prices over this and the next decade, beyond 2040 ammonia generated by wind and solar may reach a price of between €300 and €330 per ton.

The Danish Energy Agency has granted permission, to two power-to-X specialists, for the development of innovative projects without having to comply with the country’s energy legislation. This exemption is part of an upcoming pilot scheme to support new clean energy technologies, including green hydrogen.

BP, Iberdrola and Enagás will power a 20 MW electrolyzer with 40 MW of solar in Spain. Automotive manufacturers Hyundai, Stellantis, Toyota and BMW sent a letter to European Commission Vice-President Frans Timmermans asking to support the continued expansion of a 700 bar hydrogen refuelling network in Europe.

Big German conglomerates such as Siemens, RWE and Vattenfall keep pushing for green hydrogen development through different projects. Germany’s first offshore hydrogen pipeline is being planned by RWE itself, Shell, Gascade and Gasunie, and should be commissioned in 2035. Siemens is planning hydrogen projects in the 5 MW to 50 MW range, for industrial and mobility applications.

An group of international scientists has developed a mathematical model to design hybrid renewable energy systems relying on pumped hydro storage for islands. According to their analysis, which was applied to the Ometepe island in Nicaragua, a similar system could provide a cost of energy ranging from €0.047/kWh to €0.095/kWh.
