Construction begins on world’s largest integrated green hydrogen, ammonia plant

In other news, German energy company Uniper said it will test a new salt cavern built for hydrogen storage, while Serbia and Hungary signed a memorandum of understanding to collaborate on renewable hydrogen.

Okra Solar secures $3 million to bankroll mesh-grid expansion

Australian renewable energy tech start-up Okra Solar has raised $3 million to scale up distribution of its solar-based hardware and software solutions and electrify more than 290,000 off-grid homes in Nigeria in the next three years while expanding its operations in Haiti and other countries.

Storing renewables with high-rise elevators

Lift Energy Storage Technology is a proposed long-term storage solution that relies on elevators to bring solid masses to the tops of buildings in charging mode. It then lowers the same mass to produce electricity in discharge mode.

Robot dog for PV plant monitoring

Spanish renewable energy company Acciona is using a robot dog, instead of drones, to monitor a solar park in northern Chile. The device has a built-in thermal vision system that generates thermographic reports on the status of the different PV plant components, as it walks between the panel rows following a programmed route.

Green hydrogen could disrupt global trade, bilateral energy relations

While there are still many uncertainties as to the way in which hydrogen trade might evolve and change economic ties and political dynamics between countries, experts agree that green hydrogen can bring winds of change to the global energy arena. According to the International Renewable Energy Agency, significant geoeconomic and geopolitical shifts are just around the corner.

Solar panels host microbes that may be used for biotech applications

Scientists in Brazil have found that photovoltaic modules may be a repository of specialised microbes in tropical regions. According to them, these micro-organisms may be used in sunscreens, pigments for processed foods, chemicals, textiles, pharmaceuticals, and cosmetics.

HDF to construct baseload power plant using green hydrogen, plans Australia expansion

The project includes a solar park coupled with what HDF Energy claims is the “largest green hydrogen storage of intermittent electricity sources” at 128 MWh. Importantly, the company also simultaneously announced expansion plans into Australia, saying its hydrogen technology will soon be available here, adding that it has “projects already in development for Australia”.

Energy storage with recycled batteries from Brazil

Energy Source, a Brazilian battery specialist, is currently providing energy storage services with reused and recycled batteries. Battery recycling and related metals recovery are conducted separately, without the burning of materials.

Using the oceans’ depths to store renewables, compress hydrogen

Underwater gravity energy storage has been proposed as an ideal solution for weekly energy storage, by an international group of scientists. The novel technology is considered an alternative to pumped-hydro storage for coasts and islands without mountains that are located close to deep waters, and may also be interesting for PV if used to store green hydrogen.
