New electrolyzer to split saltwater into hydrogen
Chinese scientists have developed a new way to split seawater into hydrogen without using a separate desalination process. They incorporated a self-breathable waterproof membrane and a self-dampening electrolyte (SDE) into the electrolyzer, so water migrates from the seawater across the membrane to the SDE, without extra energy consumption.
2022 review in trends: Inverters
It was a good year for the inverter market. Strong demand was only stifled by supply chain limits, but new inverters are less innovative and show a slower evolution in improvements. Nevertheless, more versatile options are emerging in response to the energy crisis.
