Projections towards 2050 of the global hydrogen (H) demand indicate an eight-fold increase in present-day hydrogen consumption. Leakage during production, transport, and consumption therefore presents a large potential for increases in the atmospheric hydrogen burden. Although not a greenhouse gas itself, hydrogen has important indirect climate effects, and the Global Warming Potential of H is estimated to be 12.

Article Synopsis
- Airborne measurements are a reliable way to assess greenhouse gas emissions in urban areas, although they require high precision and strong signal detection.
- A new active AirCore system was developed, capable of conducting long-duration atmospheric sampling aboard a lightweight aircraft, enabling simultaneous measurement of gases like NO, CH, CO, and CO2.
- Flights over Groningen, Utrecht, and Rotterdam showed that estimated NO emissions in Rotterdam were significantly higher than previously reported, while CH emissions across all three cities aligned closely with existing Dutch inventory estimates, showcasing the effectiveness of the AirCore system for precise GHG measurement.
Article Synopsis
- Scientists studied methane gas from dairy cows on a farm in the Netherlands using a special flying device (UAV).*
- They found out how much methane is released and created methods to get better data on these emissions.*
- By improving their measurements with wind data and a special gas, they can make more accurate estimates of methane from farms.*
