Off-grid floating PV-desalination system for hydrogen production
Scientists have simulated a solar-powered hydrogen production system comprising 32,050 photovoltaic panels, a pumping system, a seawater reverse-osmosis desalination unit, an electrolyzer, and a hydrogen storage tank. Operation of the system in Oman could potentially yield a levelized cost of electricity of $0.05/kWh and a levelized cost of hydrogen of $9.5/kg.
BNEF flags potential global solar slowdown in 2026 as China cools
BloombergNEF (BNEF) projects a slight year-on-year dip in global solar additions in 2026 as China’s growth eases, even as installations elsewhere continue to rise.
The Hydrogen Stream: CMB.Tech secures China green ammonia offtake
CMB.Tech has secured an offtake agreement for renewable ammonia from CEEC Hydrogen Energy’s 800 MW wind-and-solar-powered project in China, while Germany’s Gascade Gastransport said it has converted about 400 km of gas pipelines to form a new hydrogen transport corridor.
BYD surpasses 1.5 million residential storage systems worldwide
BYD says global installations of its BatteryBox residential energy storage systems have increased by 500,000 since June 2024, lifting the total past 1.5 million worldwide.
EU countries to pilot subscription model for heat pumps
An EU-funded project is introducing a heat pump on subscription model designed to increase the uptake of heat pumps in rented accommodation, with pilot actions planned in Austria, France and Greece.
Dutch regulator finds grid fees for rooftop solar are reasonable
The Dutch competition regulator rules feed-in costs for home solar are not unreasonable. It is calling on energy suppliers to charge feed-in costs uniformly to make it easier for consumers to compare contracts.
Emmvee starts production at 2.5 GW solar module line in India
With the new line becoming operational, the company’s total solar module manufacturing capacity has increased to 10.3 GW.
US battery market faces make-or-break year in 2026
Rising demand, tighter economics, and higher expectations for performance and reliability are putting the US energy storage industry under pressure heading into 2026.
Irish solar rises in 2025 as government plans €18.9 billion of grid upgrades
Provisional data from the Sustainable Energy Authority of Ireland (SEAI) for 2025 showed that monthly utility-scale solar generation increased from an average of 0.73 TWh in 2024 to 0.99 TWh in the first nine months of 2025.
Too much to choose from, too little to decide
Market pressure in the solar and storage sectors often favors low-cost solutions, but long-term success depends on balancing price, quality, and reliability for assets designed to operate for decades. Numerous examples, from low-grade silicon modules to residential hydrogen and redox flow storage, show how technically ambitious products can fail when costs, complexity, or durability are misjudged.
