The German government says that the H2Mare OffgridWind project in Denmark has connected two electrolyzers to a wind turbine for hydrogen production, while Ontras Gastransport and H2 Energy Europe have agreed to define the technical and commercial framework for hydrogen transportation in its Green Octopus Mitteldeutschland pipeline project.

GreenGo Energy will also collaborate with Lodestone, a local iron mining company, to integrate green hydrogen into steel production, aiming to set new standards for sustainable manufacturing.

In its four years of operation, the world’s first semi-submersible floating offshore wind farm, WindFloat Atlantic, has surpassed anticipated production figures, achieving a total cumulative output of 320 GWh.

Oxford PV is delivering its first commercial perovskite solar modules to US customers. The 72-cell solar modules have an efficiency of 24.5% and, according to the company, can generate up to 20% more energy than conventional silicon modules.

Earlier this year, the company set a new efficiency world record of 26.9% with its 60-cell residential-sized module, unveiled at this year’s Intersolar. It claims to have a “clear roadmap” to bring the technology to over 30% efficiency.

A research team at Osaka University in Japan has developed green light wavelength-selective organic solar cells (OSCs) that transmit blue and red light necessary for crop growth and use green light, which contributes only a little to photosynthesis, for power generation.

For instance, its ten-passenger “Nirva” boat can go 200 km (124 miles), its massive 120-passenger “Vega” model can go 225 km (140 miles), and its 12-person “Bumblebee” electric boat can go 250 km (155 miles) and reach a top speed of 25 knots (~29 mph).

The academics also found that the production of the sisal fibers emitted about 60% less CO2 and required 50% less energy than PET backsheets. “Solar panels with sisal fiber sheets exhibit adequate tensile strength and impact resistance and reduce operating temperature by 2–3 C, ensuring stable operation and minimizing heat loss,” they added.

Mingyang Smart Energy has installed what the company claims to be the world’s largest single-capacity offshore wind turbine, the MySE 18.X-20 MW, in Hainan, China.

The unit features flexible power ratings ranging from 18.X to 20 MW, coupled with rotor diameters from 260-292 metres, covering a maximum swept area equivalent to nine soccer fields.

According to Mingyang’s website, the wind turbine can withstand winds up to 79.8 m/s.

The group designed a sputtered multilayer WSe2 film with a thickness of 15−30 nm for applications on on a 150 mm wafer via a selenization process based on either a solid-source selenium (SS-Se) at 900 C or low-thermal-budget hydrogen selenied (H2Se) precursors at 650 C. The resulting WSe2 film had an energy bandgap of 1.2 eV to 1.3 eV, which the scientists described as near-ideal for solar energy harvesting.

The Baltic nation of Estonia has launched an ambitious 100% renewable energy goal for 2030. As part of that goal, energy industry stakeholders plan to showcase the entire country as the world’s first nationwide, integrated “hydrogen valley” hub, with a focus on green hydrogen.
