South Korean scientists have developed a highly selective palladium composite membrane on porous metal supports to cut the ammonia content of the permeated hydrogen stream. Dutch researchers, meanwhile, have presented two alternatives to this strategy – increasing the thickness of the membrane selective layer, or using a purification unit in the permeate of the membranes.
TCL Zhonghuan has announced wafer price cuts, Shenzhen Energy unveiled a plan to build a 2 GW solar-storage project, and the Chinese authorities have announced measures to expedite grid connections for new solar and wind plants.
Kaco has launched a new line of blueplanet NX3 three-phase string inverters for applications ranging from small residential rooftop arrays to projects on commercial buildings. They have outputs between 3 kW and 33 kW, a maximum efficiency of 98.0%, and a maximum European efficiency of 97.6%.
Ambitious targets for solar energy generation present challenges to an industry keen to explore new avenues for solar production. Neil Spann, chief executive of UK thin film solar manufacturer Power Roll, describes a commercial solution to the problems of over reliance on silicon solar modules.
UK-based Gravitricity plans to set up a pilot demonstration project for its gravity energy storage systems in India.
Hitachi Energy is delivering the 35 MVA Darwin-Katherine Battery Energy Storage System in Australia’s Northern Territory. Now that civil and building works have been completed at the $30.2 million big battery site, the company will deploy tech to provide virtual inertia and system strength services to the grid.
Researchers have assessed the economic viability of utility-scale floating solar arrays in Europe and have determined that such projects are already cost-competitive in several southern European countries. They claim floating PV could become competitive across Europe if capital costs are reduced by 12%.
A proposed 75 MW solar-to-hydrogen facility in California could mark the start of Fusion Fuel’s green hydrogen vision for the United States.
Chinese scientists have made mono cast silicon ingots with high purity and low manufacturing costs. The new method will help industrial casting manufacturers to improve the cost performance of casting ingots.
A research group has developed a new methodology that shows PV systems located in the same area could have similar distributions of power ramps. Their three-step method could be used for the dimensioning of rooftop arrays and the scheduling of daily operations.
