Dozens of cities and states have passed laws or resolutions targeting 100 percent carbon-free electricity, including California. But how will the state meet its goals? A new Wärtsilä study indicates power-to-gas (PtG) technology could be the missing “puzzle piece” to help California meet its renewable energy goals faster and less expensively than its current plan. David Robert’s Vox article, “The missing puzzle piece for getting to 100% clean power” offers insight into this technology and study.
- California’s current renewable energy plan relies heavily on solar, wind, hydropower, and battery storage, and does not reach full carbon neutrality by 2045.
- Variability and cost of battery storage technology are two major hurdles facing California’s transition to 100 percent clean energy
- According to Wärtsilä’s newest study, PtG technology makes California’s 100 percent target cheaper, more efficient and reduces more carbon emissions
- Vox reporter David Roberts writes, “Wärtsilä’s study should, at the very least, awaken California legislators and regulators to [the] crucial role that green hydrogen and/or PtG could play in holding down the costs of a fully carbon-neutral electricity system. If hydrogen and hydrogen fuels are to play that role, they need aggressive policy support to accelerate their progress down the cost curve.”
Path to 100% Perspective:
States, cities and countries around the world are debating and implementing ambitious 100 percent clean energy targets. Some detractors argue that 100 percent clean energy simply cannot be done without expensive battery storage or that coal plants should stay online in the meantime. This new Wärtsilä indicates that the path to 100 percent renewables is not only possible, but it doesn’t have to cost a fortune. According to the study’s Optimal Path scenario, PtG technology is the best choice to get California on the path to 100 percent faster, cleaner and more affordably than its current plan or a more robust plan that banishes all thermal plants from the grid.
