The Hydrogen Stream: Germany to use hydrogen ‘in all sectors’
The German authorities have announced plans to double domestic electrolysis capacity to 10 GW by 2030, BloombergNEF has reported that green hydrogen became competitive with gray hydrogen earlier than expected, and Chinese researchers have presented new research on microbial hydrogen production.
How big must hailstones be to damage PV systems?
The hail storms that occurred recently in northern Italy damaged several photovoltaic systems. pv magazine Italy retrieved a report from the Vrije Universiteit Amsterdam from 2019 which tried to shed light on the damage caused to solar installations by hail by analyzing the effects of a severe hailstorm that occurred in the Netherlands in 2016. According to their assessments, damages to PV modules are mostly derived from hailstones of at least 3 cm in diameter.
The Hydrogen Stream: Gasunie reports strong interest in salt cavern H2 storage
Dutch gas supplier Gasunie says several market participants have reserved capacity in the first salt cavern for large-scale hydrogen storage near the Dutch city of Groningen. According to current planning, the first cavern will be operational by 2028.
