Renewable Electricity Set To Power Past Coal And Gas By 2025

At-a-Glance:

Global economic growth has dropped this year because of COVID-19 and the energy sector has been among the hardest-hit, with oil prices at one point turning negative as demand slumped.

However, one part of the energy industry has defied the downturn – and is set to post record growth this year and next. Cost reductions and sustained policy support are set to drive strong growth in renewable energy. By 2025, renewables will have usurped coal to become the biggest source of electricity generation globally.

Key Takeaways:

  • The International Energy Agency (IEA) Renewables 2020 report says that almost 200GW of new clean power capacity will be installed in 2020, almost 90 percent of all new power capacity around the world.
  • Renewable electricity generation will increase by 7 percent globally in 2020, underpinned by the record new capacity additions, the Agency says. This growth comes despite a 5 percent annual drop in global energy demand, the largest since World War II.
  • India’s renewable energy sector is set to double in 2021.
  • Global growth in renewable capacity in the first 10 months of 2020 is already 15 percent higher than the same period last year, despite the pandemic, and growth is set to continue.
  • But while renewables in the power sector are going from strength to strength, the COVID crisis has hit electric vehicles and renewable heat hard

Path to 100% Perspective:

As wind and solar power become increasingly cost-competitive, investments in traditional, inflexible base load plants such as large coal, nuclear, and gas combined-cycle plants are declining. This signals an end to the era of large, centralized power plants that run on fossil fuels.

Global financial trends reflect this dramatic shift, with renewable generation attracting more investment dollars than fossil-powered generation year after year. In 2018, investment in renewable power capacity was about three times higher than the amount invested in new coal- and gas-fired generation combined, according to the global renewable energy organization REN21. Worldwide investment in renewables has exceeded $230 billion for nine years in a row.

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.

Missing Pieces of Decarbonization Puzzle Realized

Jussi Heikkinen, Director of Growth & Development, Americas
Wärtsilä Energy Business

These are exciting times as the renewable energy future is a focus for so many organizations and governments around the world, as indicated by attendance of the Wärtsilä sponsored webcast hosted by GreenBiz on November 19, 2020, Missing Pieces of Decarbonization Puzzle Realized. Emerging technologies are moving closer to reality, which makes ambitious energy goals more realistic and the path to 100 percent renewable energy is now within reach.

A place where the transition to renewables has progressed quite far already is California. The lessons learned along the way have been plentiful, but powerful nonetheless. The record-breaking heat wave that swept across the western part of the country and caused a series of blackouts in the Golden State, offered additional modelling opportunities to demonstrate the most effective mix of energy to accommodate any extreme weather situation during the transition, and to meet clean power mandates.

The big challenge facing California and the rest of the world is how to integrate renewables into the grid while building security of supply and a sustainable power system with an affordable plan for everyone involved.

That’s why Wärtsilä launched its Path to 100% initiative. We believe a 100% renewable energy future is possible, practical and financially viable so we assembled a community of experts to produce solutions based on science and engineering. This fall, we published a white paper that describes the Optimal Path to decarbonization for California using new hourly load data provided by this summer’s extreme heatwave.

In the whitepaper, Path to 100% Renewables for California, we modelled an approach for  California to reach its climate and clean power goals faster, at a lower cost to ratepayers, all while maintaining system reliability.

The “Optimal Path“ includes renewable carbon neutral fuels – hydrogen and synthetic methane. Curtailed renewable electricity is used in the process with water to produce hydrogen, and carbon is captured from air to produce synthetic methane with hydrogen. These fuels are used in power plants to provide a long term energy storage for seasonal and weather management needs. In the Optimal Path scenario, Renewable Portfolio Standard (RPS) commitments would actually be reached by 2040, five years ahead of schedule.

Generation costs in the “Optimal Path” scenarios are between 50 and 54 dollars per megawatt hour in 2045, while these costs would be almost 3 times higher if California opted to use only solar, wind and storage to build the power system. This cost difference is excessive and not beneficial for industries or households to pay. Additionally, carbon emissions are at net zero in 2045 in both scenarios.

How can California get on the Optimal Path to a renewable energy future? One recommendation is to recognize carbon neutral fuels – as presented above – to be counted as renewable for RPS purposes. This would enable the utilities to start looking for ways to invest and use such fuels to the benefit of California.

Another state aggressively pursuing renewable energy goals is Texas. Co-presenter and Electric Reliability Council of Texas (ERCOT) Principal of Market Design and Development, Kenneth Ragsdale shared the Lone Star State’s progress on integrating renewables into the power system.

Climate Imperative’s Executive Director, Bruce Nilles offered a big picture perspective on electricity generation capacity and the commitments needed to accelerate decarbonization.

Top Solar States Per Capita 2012 vs. 2020 — CleanTechnica Report

At-a-Glance:

CleanTechnica has developed a new report on the top solar power states per capita, by comparing the results from the first half of 2020 with the results from 2012. Also note that this report does not include all 50 states, unlike the previous one, because the data back in 2012 didn’t include all 50 states. It just included the top 25 states in terms of overall solar power capacity. For the full 2020 ranking, see this report. To learn more, read Top Solar States Per Capita 2012 vs. 2020 — CleanTechnica Report.”

Key Takeaways:

  • Two things to note in the two charts. First, how much solar power capacity per capita has increased in each of these states. Secondly, how the rankings have shifted around.
    • Nevada rose from #3 in 2012 to #1 in 2020
    • California rose from #6 in 2012 to #3 in 2020
    • North Carolina rose from #11 in 2012 to #5 in 2020
  • The US Solar Energy Industries Association (SEIA) has some interesting “quick facts” on each state in the country. Below are a few comparative highlights:
    • California-first in the nation
      • Total Solar Investment in State: $68,148.93 million.
      • Solar Companies in State: 2,006
    • North Carolina-second in the nation
      • Total Solar Investment in State: $8,999.31 million.
      • Solar Companies in State: 216
    • Arizona-fifth in the nation
      • Total Solar Investment in State: $12,772.41 million.
      • Solar Companies in State: 307
  • North Carolina jumped up the charts from #7 to #2. New Jersey had almost the opposite result, dropping from #3 to #7.

Path to 100% Perspective:

These future power systems will need four cornerstones to maintain reliable power in the clean power system of the future. The “Generation Cornerstone” is foundational to a 100% renewable future when wind and solar farms will generate most electricity. The “Constant Balance Cornerstone” keeps power flows on the grid balanced, minute by minute by collecting excess power in short-term battery-style energy storage with typical durations of one hour or less that continuously charge and discharge as needed to supply constant, reliable power. The “Daily Shift Cornerstone” ensures the lights stay on by shifting overbuilt renewable power during the day to meet load and charge storage, and discharging that stored energy at other times of the day when it’s needed. The “Reliability Cornerstone” ensures system reliability by using flexible generation to make up the difference.
