California faces challenges with hydrogen energy plan

Gov. Gavin Newsom's initiative to expand hydrogen as a renewable fuel in California is under scrutiny due to potential environmental risks.

Aaron Cantú reports for Capital & Main.


In short:

  • California is trying to boost its hydrogen fuel industry with significant federal support, despite concerns over increased emissions.
  • The proposed state Senate Bill 1420 seeks to define clean hydrogen sources, but may still allow for pollution-heavy methods.
  • Critics argue the plan may not effectively reduce overall emissions and could divert clean energy from other uses.

Key quote:

“If we want to move away from fossil fuels, we have to ask, ‘What is the alternative?’ It all points to renewable hydrogen.”

— Janice Lin, President, Green Hydrogen Coalition

Why this matters:

Hydrogen fuel, often lauded for its ability to power vehicles and industries without emitting carbon at the point of use, holds promise for significant reductions in greenhouse gas emissions. Despite the environmental benefits touted, the production of hydrogen, especially through methods that rely on natural gas, can lead to increased emissions of methane and other pollutants unless carefully managed. This aspect of hydrogen fuel production has sparked a debate about whether the technology will indeed lead to a net reduction in emissions or merely shift the problem elsewhere.

Climate change is accelerating health threats worldwide

Climate change is accelerating health threats worldwide

The Lancet Countdown - established in 2016 to annually assess the effects of climate change on health - released a ten year report and accompanying editorial.


In short:

  • For the first time, the report quantifies heat-related deaths attributable to climate change, estimated at about 370,000 a year. The past 11 years have been the hottest ever recorded.
  • The report examined 54 indicators of climate change-driven health impacts and found that many health threats had increased or accelerated over the past decade.
  • Populations least responsible for climate change are experiencing the highest impacts.


Key quote:

“Over the past 10 years, a strong evidence-based case has been made that responding to climate change could be the greatest health opportunity of the 21st century.”



Why this matters:

The report points out how fossil fuel interests are blocking progress on climate change. It tracks not only heat-related deaths, as mentioned above, but also other climate related effects on health caused by floods, landslides, droughts, viruses, and more. It also tracks improvements, for example, estimating that the transition to clean energy prevented 400,000 deaths in 2023 just through improved indoor air quality. Health professionals are trusted sources of information and can speak for policy change and action for a healthier future.
