Scientists in Malaysia have conducted a techno-economic-environmental study of a green fueling system for a ferry that runs between islands in their home country. Using 40,000 solar panels, they were able to power two round trips round-trips per day. Annual CO₂ reduction was measured at 23.75 million kg.

Scientists in India have designed a system that uses PV panels, a proton-exchange membrane fuel cell, battery storage, and a supercapacitor. It also relies on an adaptive neuro-fuzzy inference system-based MPPT that reportedly achieves an efficiency of 98.7%.

Scientists in Tunisia have investigated the impact of PV panel tilt and water quality on green hydrogen production and have found that, with a variable orientation PV panel, the hydrogen generator could reach an efficiency ranging from 32% to 62% using demineralized water and 45% to 65% with distilled water.

Researchers have developed a novel energy system comprising PVT panels, reverse osmosis, reverse electrodialysis, and proton exchange membranes. The proposed setup can purportedly produce 18.78 kg/day of hydrogen and 120.6 m³/day of freshwater.

Scientists have proposed a standalone system that uses freeze desalination and ice for air conditioning. It requires 10,785 square meters of c-Si bifacial PV panels and can operate throughout the day. Energetic efficiency is calculated as 17.8% during the day and 56% at night.

Researchers have simulated the operation of bifacial PV and proton exchange membrane reversible fuel cells across restaurants in five different US states. Taking into account varying rates of bifacial PV’s rearside gains, they found that LCOE was as low as $0.029 per kWh.

Researchers in Pakistan have tested several configurations of an offgrid PV-hydrogen system intended to power EV chargers. The system achieved the lowest levelized cost of electricity when it was combined with battery storage.

Researchers in Spain have made a comparative analysis of annual PV-powered hydrogen production for direct and indirect configurations and have found that indirect systems not only produce more hydrogen but also that they show higher resilience to module power losses.

Competition is intensifying in the electrolyzer space. With the International Energy Agency (IEA) expecting 380 GW of hydrogen production capacity in 2030, four different technologies will likely become prominent as demand spikes. We take a look at the market.

Plus there is news this week of a green hydrogen tie-up in India, plans for another German production facility, and of new hydrogen transport networks for Switzerland and the U.S.
