Wärtsilä launches project to develop 100% hydrogen-fueled engine and power plant concept by 2025

At-a-Glance:

Technology company Wärtsilä announced an initiative to develop an engine and power plant concept that will be able to run on 100% hydrogen by 2025, in a move that could contribute to widespread decarbonization of the electric power industry and other sectors. The company’s new project aims to develop that concept by 2025, and commercialize it by the end of the decade.

Key Takeaways:

  • Roughly one in three people in the U.S. live in a state or city that is trying to transition to 100% clean electricity, according to Natural Resources Defense Council (NRDC), with the Biden administration pushing for a national 100% standard by 2035.
  • “Our base engine concept is very flexible — it can take very different types of fuels already today. But now, we’re evolving this flexibility up to 100% hydrogen,” Wärtsilä CEO Håkan Agnevall said.
  • “At the end of the day, when 100% hydrogen is available, our engines can run with that and, with new engines coming in, we can make the transition with the small changes that are needed for the engines,” Jukka Lehtonen, Vice-President of Technology and Product Management of Energy Business at Wärtsilä Energy said.
  • Some utilities are already exploring the potential of hydrogen — NextEra Energy, for instance, views it as a key piece of deep decarbonization efforts and has said it’s rolling out small hydrogen projects.

Path to 100% Perspective: 

Decarbonization is technically and commercially feasible with technologies that are already available at scale. These technologies include:

  • Wind and solar photovoltaic (PV) as the main sources of primary energy
  • Short-duration battery energy storage.
  • Flexible thermal balancing power plants to provide firm and dispatchable capacity.
  • Sustainable fuels used in thermal balancing power plants, forming long- term energy storage. Sustainable fuels include green hydrogen and hydrogen-based fuels, such as ammonia, methanol and synthetic meth- ane produced from renewable sources.

Tucson Electric turns on its biggest renewable-energy plants to date

At-a-Glance:

The electricity powering most of Tucson, including the University of Arizona, got a little cleaner the week of May 3, as Tucson Electric Power Company (TEP) switched on its biggest solar and wind power plants to date. To learn more, read “Tucson Electric turns on its biggest renewable-energy plants to date.” Reading this article may require a subscription from the news outlet.

Key Takeaways:

  • The 1,130 acre project, built and owned by NextEra Energy, includes 30MW of linked battery storage to bank solar power for use when the sun goes down.
    • The Wilmot Energy Center is expected to generate enough energy to power the equivalent of 26,000 typical TEP homes.
  • TEP’s biggest renewable energy resource, the 250MW Oso Grande Wind Project in New Mexico, went online a couple of weeks later. Consisting of 62 wind turbines on 24,000 acres, Oso Grande is expected to generate enough energy each year to serve about 90,000 homes.
  • With Wilmot and Oso Grande online, TEP will have 628MW of large, community-scale wind and solar resources – with the 99MW Borderlands Wind Project, being built 100 miles south of Gallup, New Mexico, coming online by the end of 2021.
  • The new solar and wind farms will help TEP toward its goal of generating 70% of its power from renewables and cutting its carbon emissions by 80% by 2035.
  • TEP has dedicated a portion of its output to provide the UA campus with “100% clean energy” under a 20-year, green energy agreement announced in 2019.

Path to 100% Perspective:

Electric utilities such as TEP are embracing their role in reducing climate emissions by shifting to renewable energy sources, like solar and wind. As a growing number of cities, states, and nations set goals for increasing amounts of renewable energy, economics is helping bring those plans to fruition. Over the past 20 years, the cost per kilowatt of wind power plants has decreased by 40%, while the cost of solar generation has dropped by 90%. The cost-competitiveness of renewables is making it possible to accelerate decarbonization of power systems such as TEP.
