Synthetic Fuels Are the Final Piece of the 100% Renewable Grid

GTM Creative Strategies May 12, 2020

In this episode, Path to 100% community expert Matt Rautkivi of Wärtsilä and hosts from Greentech Media explore how to use green hydrogen to create renewable fuels  and burn those fuels to create the fully-renewable electricity system.

Electricity grids can handle a lot of wind, solar and water resources. But what will help us get from 80% renewable energy to 100% renewable energy?

The missing piece may be renewable synthetic fuels.

Find out more how research has progressed, where technology is going and why experts are confident that renewable fuels are going to become a vital solution.

The Key to Unlocking 100% Renewables

GTM Interchange Podcast February 27, 2020

As cities, states and countries make tough choices about cleaning up their power systems, they need to rely on sophisticated models. In this episode, Path to 100% community expert David Millar, General Manager for Utility Market Development at Wärtsilä North America, Joe Ferrari and Greentech Media hosts take a look how utilities are planning for the 100 percent renewable energy future and power systems modeling 

The 100 percent renewable energy future doesn’t start with a country, state or region. It starts with a city. One power plant in a city, in fact. In Glendale, California.

Duke’s Emission-Free Path Doesn’t Include Quitting Fossil Fuel

At-a-Glance

Duke Energy Corporation is working toward achieving net-zero carbon emissions by 2050 and recently announced that natural gas is a key part of its strategy to meet this goal. In its latest climate report, the utility argued that natural gas remains crucial as demand peaks, to balance electric grids and continues to be more affordable than battery storage. To learn more, read “Duke’s Emission-Free Path Doesn’t Include Quitting Fossil Fuel.”

Key Takeaways

  • Over time, Duke will cut back on its natural gas use as it continues toward its net-zero emissions goal.
  • According to the report, battery storage could cost three to four times as much as using natural gas.
  • Duke will also leverage its nuclear fleet and may require advancements in long-term energy storage and carbon-capturing technologies.
  • In an interview, Sarah Venuto, Duke’s vice president of public policy, remarked, “The fact of the matter is we are committed to this goal. That does not mean it’s going to be without challenges.”

Path to 100% Perspective

Duke’s climate report indicates the utility can meet its net-zero carbon emission goal more affordably and easily by leveraging natural gas. While the utility intends to eventually cut back on natural gas use in the long term, relying on natural gas on its path to net-zero emissions is a financially feasible decision for ratepayers. This move indicates that a mix of different technologies and fuels will be important for reaching zero carbon targets.
