6 Out-of-the-Ordinary Energy Concepts From 2020

At-a-Glance

It’s been a “business-as-usual” year for renewables, despite the societal upheaval wrought by the coronavirus pandemic. Most 2020 headlines continue to highlight conventional renewable segments such as solar and energy storage. On the margins, virtual power plants have gone mainstream and green hydrogen has emerged as the energy carrier of choice for tomorrow’s fuel systems. But COVID-19 did little to dampen enthusiasm for more obscure energy concepts. To learn more, read “6 Out-of-the-Ordinary Energy Concepts From 2020.” 

Key Takeaways

  1. Filipino engineering student, Carvey Ehren Maigue has developed Aurora Renewable Energy and UV Sequestration or AuREUS, which uses vegetable-based panels as tinted films that can be applied to existing surfaces, such as walls and windows.
    • AuREUS’ ability to capture diffused ultraviolet rays is said to deliver a capacity factor of up to 50 percent, compared to a maximum of around 25 percent for photovoltaic (PV) solar energy.
  2. Salient Energy emerged from Shell’s GameChanger program with a zinc-ion battery chemistry believed to be cheaper, safer and longer-lasting than anything else on the market.
    • Salient claims its proprietary cathode materials store energy in zinc in a way that has never been commercialized before.
  3. Puerto Rican startup ReSynth specializes in “fuel enhancement” to reduce greenhouse gas concentrations from diesel and marine oils.
    • The fuel emulsion cuts sulfur and nitrous oxide emissions as well as carbon. Plus it has been approved by the U.S. Environmental Protection Agency, the Department of Energy and the U.S. Coast Guard. It works with engines from major manufacturers such as Wärtsilä.
  4. Spanish firm Vortex Bladeless was founded in 2014, but 2020 was a year for notable milestones for the innovators. Vortex launched a small-scale product, less than three feet tall, to compete with low-power off-grid PV.
  5. The Ocean Grazer concept, based at the University of Groningen in the Netherlands has developed the Ocean Battery which stores energy by pumping fresh water into flexible bladders that are deflated by the pressure of the seawater column when power is needed.
  6. Alberta-based Eavor Technologies believes one of its Eavor-Loop systems can pull energy from the center of the earth to heat 16,000 homes or produce industrial-scale electricity via heat-to-power engines.

Path to 100% Perspective

The path to 100% has not already been paved, therefore, commitments to innovation and creativity are essential to developing solutions for different communities, regions and utilities. However, grid operators also navigate balance between obscure energy concepts and sustainability for power systems that energize communities around the world. The possibilities are endless as entrepreneurs and energy experts continue to collaborate towards flexibility and sustainability in order to reach a renewable energy future.

Leveraging Coronavirus Stimulus to Take a Giant Leap Toward Decarbonization

At-a-Glance

While electricity demand has faltered during the global pandemic, the share of wind and solar generation has continued to increase. Wind and solar produced 10 percent of global electricity between January and June in 2020. In the European Union, renewables accounted for 33 percent of all power generation. According to the International Energy Agency, the EU’s renewable energy production was higher than its fossil fuel generation between February and early July of this year. The increased role of renewables has highlighted the investments necessary to make the transition to a 100 percent renewable power system faster and more economically efficient. To learn more, read “Leveraging Coronavirus Stimulus to Take a Giant Leap Toward Decarbonization.” 

Key Takeaways

  • While there are nuances depending on local circumstances, one significant takeaway is that the power system as a whole can handle a more rapid shift to renewables than grid operators have long assumed. 
    • “What we found was the energy system can cope really well with much more renewable power and that it’s possible to raise the ambitions around adding more clean energy,” said Sushil Purohit, president of Wärtsilä Energy.
  • Charting a more rapid and financially efficient transition to a 100 percent renewables future was a primary objective of Wärtsilä’s recent report, Aligning Stimulus With Energy Transformation, based on its Atlas modeling. 
    • The report demonstrates how using energy-related stimulus investments to support clean energy could speed decarbonization in five key countries: the U.S., the United Kingdom, Brazil, Germany and Australia.
  • According to the report, 54 percent of the $400 billion pledged has been targeted to benefit fossil-fuel-based energy, while 36 percent has been devoted to clean energy. 
    • In the U.S., more than 70 percent of the current $100 billion allocated for energy stimulus was pledged to fossil fuels, compared to less than 30 percent for clean energy.

Path to 100% Perspective

Beyond the issue of decarbonization, this is a missed opportunity to spark near-term job creation. According to a report by McKinsey & Company, every $10 million of government spending on renewables creates 75 jobs, while the same amount invested in fossil fuels creates 27 jobs. For the U.S., reallocating the $72 million of the COVID-19 energy stimulus currently earmarked for fossil fuels to clean energy would result in 544,000 new jobs, 175 percent more than would be produced in the traditional energy sector. In addition, these investments would result in 107 gigawatts of new renewable energy capacity and a 6.5 percent increase in renewable electricity generation, from 17.5 percent to 24 percent.
