Hydrogen and hydrogen-based fuels will not be able to move forward fast enough to replace fossil fuels and tackle climate change, according to a German-Swiss research team that claims direct electrification alternatives are cheaper and easier to implement. The scientists cite too-high prices, short-term scarcity and long-term uncertainty, as the main reasons for their skepticism, which has caused a stir in academic circles.

German scientists have proposed a new design for stacks used in redox flow batteries. Through a powder-to-roll process, a device that weighs 80% less than a conventional stack was fabricated.

Researchers in Germany claim to have overcome the primary hurdle in the development of large-area perovskite PV modules – scaling up from the cell to the module level. They achieved an efficiency of up to 16.6% on a module surface of ​​more than 50 centimetres squared, and 18% on a module with an area of 4 centimetres squared.

Germany’s first offshore hydrogen pipeline is being planned by multiple partnering companies and is expected to be commissioned in 2035. Meanwhile, Siemens is planning hydrogen projects in a 5 MW to 50 MW range for industrial applications and a consortium of conglomerates is maintaining pressure on EU to develop green hydrogen.

The database brings together photovoltaic performance data and meteorological values from PV systems located in all climate zones. It is being built by an international consortium including the Fraunhofer Centre for Silicon Photovoltaics CSP, and the Anhalt University of Applied Sciences.

Annual battery storage installations will exceed 10 GW/28 GWh in 2021, following a particularly strong year in 2020, despite the challenges created by the global pandemic, writes IHS Markit analyst Mike Longson. Combined solar and storage will be a core focus for new deployment in 2021, as the front-of-the-meter and behind-the-meter energy storage markets are both expected to grow significantly in the months ahead.

The joint feasibility study between Australia and Germany, HySupply, to determine the viability of a renewable energy-based hydrogen supply chain between the two countries, has progressed again after global firm RWE Supply & Trading and Australian-based The Hydrogen Utility signed a Memorandum of Understanding which could see green ammonia exports from South Australia to Germany’s LNG Terminal in Brunsbüttel.

The company being acquired, Azur Space, produces triple-junction space solar cells with an average efficiency of up to 30% and is planning to develop ultra-thin solar cells with up to 35%.

The cell reached 26.0% efficiency and showed open-circuit voltage values of up to 732 mV. It was fabricated with a back junction (BJ) design with a full-area p-n-junction at the back surface.

A 1.2 MWp installation featuring more than 4,500 solar panels has sheltered a berry crop from high temperatures and damp to strengthen the claims made by agrivoltaics companies that their systems can offer climate change mitigation as well as clean energy.
