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


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.
