Los Angeles now has a road map for 100% renewable energy

At-a-Glance:

Los Angeles is one of the last places in California still burning coal for electricity — and if all goes according to plan, it could become one of the country’s first major cities to nearly eliminate fossil fuels from its power supply. In a first-of-its-kind study commissioned by the city and released, the National Renewable Energy Laboratory concluded L.A. is capable of achieving 98% clean energy within the next decade and 100% by 2035, meeting one of President Biden’s most ambitious climate goals. And it can do so without causing blackouts or disrupting the economy, the federal research lab found, undercutting two of the most common arguments used by opponents of climate action.

Key Takeaways:

  • The NREL study team included nearly 100 people and was aided by the “Eagle” supercomputer at the research lab’s Golden, Colo., headquarters.
  • They conducted an energy systems analysis they believe to be unprecedented in scope and detail, running more than 100 million simulations since 2017 and integrating heaps of modeling data on electricity use, job creation, weather conditions, power lines and the potential for rooftop solar panels on houses across Los Angeles, among other topics.
  • Under a different scenario, L.A. would still get about 10% of its electricity from gas come 2045, down from 24% today.
  • Every pathway outlined by NREL includes geothermal power plants, which tap the Earth’s subterranean heat and can generate climate-friendly energy around the clock, as well as pumped hydropower, which can store solar and wind longer than a typical battery. Several pathways in the study also assume the city keeps its 5.7% ownership stake in Arizona’s Palo Verde nuclear plant.

Path to 100% Perspective:

California already has the natural gas infrastructure in place to follow the Optimal Path. The state’s existing gas storage capacity and distribution systems can easily provide the necessary 8 TWh of reliable, fully dispatchable renewable energy while using only 15 percent of existing underground gas storage capacity. This alleviates concerns around “stranded assets” since flexible generation plants can shift at any time to burn synthetic methane, even before 2045. California’s current plan without thermal generation would require an investment of $309 billion between 2021 and 2045 to add another 1,624 GWh of battery storage and electricity generation cost would jump to a sky-high 128 $ / MWh. However, the Optimal Path would save the state $176 billion with Power-to-Gas and thermal generation as long term energy storage between 2021 and 2045 and electricity generation cost would be $50 / MWh in 2045. More batteries without thermal generation is not affordable and is not enough to create a resilient or reliable grid.

An $11 trillion global hydrogen energy boom is coming. Here’s what could trigger it

At-a-Glance:

Storing fuel in salt caverns isn’t new, but hydrogen’s growing role in decarbonization has revitalized interest in the concept. The Advanced Clean Energy Storage project in Utah aims to build the world’s largest storage facility for 1,000 megawatts of clean power, partly by putting hydrogen into underground salt caverns. The concept is quickly gaining momentum in Europe. To learn more, read An $11 trillion global hydrogen energy boom is coming. Here’s what could trigger it.

Key Takeaways:

  • With the cost of renewables such as solar power falling, green hydrogen is being touted as one part of the energy mix that will lead toward decarbonization, with applications ranging from consumer and industrial power supplies to transportation and spaceflight.
  • By 2050, U.S. demand for hydrogen could increase anywhere from 22 million to 41 million metric tons per year, up from 10 million today, according to a study released this month by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL).
  • Bank of America believes hydrogen technology will generate $2.5 trillion in direct revenue — or $4 trillion if revenue from associated products such as fuel cell vehicles is counted — with the total market potential reaching $11 trillion by 2050.

Path to 100% Perspective:

Hydrogen has a high potential of becoming the fuel of the future, helping societies move towards decarbonization. Because hydrogen was not used as a power generation fuel in the past, the technologies to combust and use it in different applications need to be developed. Hydrogen burns with air to produce water, without any carbon emissions. It is perfect for use in 100% clean energy portfolios.
