  • The Path to a Vehicle-to-Grid Future

    Is a vehicle-to-grid future possible, where bidirectional chargers allow electricity to flow from electric vehicles back to the grid during peak demand? Given the current state of electric vehicle (EV) technology, coupled with existing pilot projects, we believe it’s more suitable to ask: what useful vehicle-to-grid applications can we implement today, and what valuable benefits await to be ...

  • Simplistic understanding of transitioning to renewables in Colorado

    We have all heard that renewables are now cheaper than coal or gas, especially after the Xcel bid that was reported in 2018, with PV with battery storage at a median price of $38/MWh (3.8 C/kWh) and Wind at $19.3/MWh (1.9 c/kWh). If this is true, why don't we just replace everything with wind and solar right now? It is, of course, a bit trickier than that. These prices, listed above, are for ...

  • Power Off-Grid Mobile Networks and Universal Connectivity: A New Business Case

    Executive Summary The accelerating drive for universal mobile access, for people and increasingly for connected vehicles and objects, means that expansion of the cellular network is outpacing that of the electricity grid. According to the GSMA, the number of off-grid base stations is expected to rise from 320,000 in 2014 to 390,000 in 2020, while base stations with unreliable ...

  • The Desire for Dial Phones Syndrome: Subsidizing Conventional Energy

    When I served as a U.S. Senate aide in the 1970’s and ran the Solar Energy Industries Association (SEIA) in the 1980’s and 1990’s, I would constantly face the lament by oil state Democrats and corporate Republicans indignantly whining about federal and state government subsidies for energy efficiency and renewable energy. Now I strongly respond that nuclear energy ...

  • 2019 Nobel Prize in Chemistry goes to the fathers of the fossil-free era

    This years’ Nobel Prizes have just been awarded and the chemistry prize recognizes the three men who developed the lithium-ion battery. It’s a technology that’s taken for granted by many of us, but this rechargeable, powerful, compact and lightweight battery has made the technology we take for granted possible. It’s why mobile phones are so lightweight and why you can use ...

  • Marine cultivation technology opening the door to the rich sources of clean energy in our oceans

    Despite the growing demand and supply of renewable energy sources, we still rely on fossil fuels for much of our global energy. But deep below the ocean, there is a source of clean carbon energy waiting to be harvested, which will go a long way to reducing our dependence on oil, gas and coal – seaweed. A recent study in Nature Geoscience estimated that seaweed floating down to ...

  • Accelerating clean energy innovation means tailoring R&D policy to technology scale and risk

    The energy sector is technology-intensive, and it has passed through several innovation-led transformations in the last two centuries The last 200 years of the history of energy could be characterised, without too much exaggeration, as five or six long periods of disruption and uncertainty, punctuated by moments of stability. The energy sector is technology-intensive, and it has ...

  • Managing Battery Charging - Using Diversion Loads

    Tcharge regulation can be relatively simple: When the I-'1/batteries are full, the controller disconnects the PV r array. Adding wind or microhydro to the system makes charge regulation more complicated, since turbines may overspecd if unloaded. Often, diversion control is the solution. Off-grid "hybrid" combinations of solar, wind, or microhydro have been around for decades. These renewable ...
