At the beginning of June 2021, during a meeting with Spanish businesspeople organized by the Portuguese-Spanish Chamber of Commerce, the Portuguese Prime Minster António Costa urged his neighbors to work on jointly exploiting the potential of plentiful lithium reserves found on the Iberian Peninsula. As Luis Ini reports from Madrid, his words reflect an increasingly evident reality: the need to achieve autonomy in the field of energy, especially in energy storage.

BMW Group said it is targeting the premium segment with its iX5 Hydrogen car, Topsoe revealed that it will invest $267 million to build the world’s largest SOEC electrolyzer plant in Denmark, and Bosch announced plans to invest $200 million in US fuel cell production.

Scientists in Switzerland put together a detailed analysis of the projected costs of designing and operating a 100 MW perovskite solar cell production line in various locations, taking in labor and energy costs as well as all materials and processing. The found that perovskite PV could be cost-competitive with other technologies even at much smaller scale, but noted that this still depends on the tech proving its long-term stability, and impressive achievements in research being successfully transferred to commercial production.

US scientists tested PV modules built with backsheets and polyvinylidene-fluoride (PVDF) layers, to replicate the degradation the material has suffered in the field of accelerated testing. By exposing the modules to multiple stresses, they were able to cause degradation in the backsheet materials. Though this did not closely match what has been seen in the field, such testing can be useful in identifying potential weaknesses.

Egypt’s hydrogen strategy is taking shape ahead of COP27 through agreements with Globeleq, Actis, and Alfanar. Elsewhere in the world, the US authorities are investing in blue hydrogen, and the city of Hamburg, Germany, has signed three agreements with Chile, Uruguay and Buenos Aires.

The urgency of rooftop solar uptake has only been accelerated by the current energy crisis, but the spread of PV to historic and landmarked buildings remains limited. In Europe, historic buildings constructed before 1945 represent at least a quarter of total building stock. To boost uptake, some municipalities are considering a loosening of their protection policies, while researchers are finding interesting byways for installation. Furthermore, building integrated PV solutions are being touted as the ideal compromise between aesthetic continuity and new generation opportunities.

Germany has launched the world’s first operational hydrogen trains and US researchers have presented a novel design for a tubular PEM fuel cell. ABB and Hydrogen Optimized, meanwhile, have expanded their strategic ties and Slovakia has moved forward with a major gas-blending pilot project.

Japanese researchers have developed a new way to improve water splitting, while South Korea has completed its largest hydrogen production complex. Scotland and England have announced new hydrogen investments, and Uzbekistan and Saudi Arabia’s ACWA Power have agreed to collaborate on hydrogen projects.

UK researchers have found a way to reduce the risk of electrocution with electric vehicles, while US utility Duke Energy said it is exploring how the Ford F-150 Lightning can serve as a grid resource. Chinese carmaker Geely posted disappointing first-half results, while IHS Markit said it expects strong uptake of battery electric vehicles in Europe through to 2030.

Scientists in Taiwan demonstrated a new way to produce high-purity lead-iodide, as a precursor material for a perovskite solar cell. By using temperature to better control the orientation of crystals, the group was able to show much higher efficiencies when the precursor was used to fabricate a perovskite layer and subsequently a working solar cell.
