Energy News for week ending June 26, 2020

Carbon Tax | Solar Limbo | StEnSea

Happy Friday afternoon.

We start we a story from the Concord Monitor, “New England Power Generators pushing for a carbon tax. A utility group representing most of the power plants in New England is supporting the idea of a tax on the carbon content of emissions, an idea supported by many economists as the simplest and most market-based way to reduce greenhouse gas production. The report by Cavicchi and Paul Hibbard of the Analysis Group for New England Power Generators Association says a price of between $25 and $70 per ton of CO2 in emissions would drive changes in electricity production, transportation and heating that could meet the region’s emissions targets. A carbon tax would raise the price of gasoline and heating oil, spurring a switch to electric vehicles and electric heat pumps. As the power grid comes cleaner with more renewable energy, that would reduce greenhouse gas emissions. This strategy, often placed under the slogan ‘electrify everything,’ is a major plank in many proposals to fight the climate emergency. The report argues that total spending would also decline by switching to electrified transportation and heating, saving customers money.”

Next up is a story from PineTreeWatch.org, “6,000 Maine solar projects remain in limbo due to uncertainty over federal decision on net metering petition. The fate of net metering in New England — and across the United States — remains unknown, but resistance to its erasure is mounting. More than 450 organizations, 57,000 individuals and 37 states submitted comments opposing a petition that could set a national precedent and end a billing practice that credits users for investing in solar. Twenty-two organizations and individuals filed support for the proposal. The public comment window ended on June 15. The Federal Energy Regulatory Commission (FERC) has not yet set a date to rule on the petition, which was filed by the New England Ratepayers Association in April…Maine Gov. Janet Mills was among those who spoke out against the petition, asking commissioners to ‘outright dismiss this petition.’ More than 6,000 ongoing projects in Maine rely on the benefits of net metering and the petition ‘would put at risk Maine’s existing renewable energy programs and the economic benefits enjoyed by thousands of citizens,’ Mills wrote in a letter to FERC. The Maine Public Utilities Commission and Maine Office of the Public Advocate also issued statements opposing the petition. ‘We’re not going away,’ said Barry Hobbins, Maine’s Public Advocate, whose job is to look out for the interests of public utility customers in Maine. ‘This could really undercut the solar industry.’”

For our new technology feature we look to the Institution of Mechanical Engineers, “Energy storage at sea could enable full transition to renewable power. A new form of pumped-storage hydroelectricity (PSH) has been developed by the Fraunhofer Institute for Energy Economics and Energy System Technology in Germany. The project, entitled Storing Energy at Sea (StEnSea), uses concrete spheres anchored on the seafloor. To store energy, water is pumped out of the spheres, against the pressure of the surrounding seawater. When the energy is required, water is allowed to flow back into the spheres, driving turbines. No upper reservoir or transmission pipe is required since the surrounding seawater provides the necessary water pressure. When compared to conventional PSH, the need for land is eliminated and structures are minimised. It eliminates the danger of dam collapse and improves storage efficiency since evaporation from the upper reservoir does not reduce the energy stored. It is proposed that spheres with a diameter of 30m would be located at a depth of 700m, giving a nominal storage capacity of 27MWh. When the actual internal volume and operating efficiency of the system are taken into account, this configuration is expected to yield 18.3MWh storage capacity with a peak power output of 5MW.”

That’s the recap for this week. Have a great weekend and as always, stay safe.
