Argonne leads creation of definitive valuation guide for pumped storage hydropower

2 days ago sarah Jonas

Argonne scientists led four other laboratories in developing definitive guidance on how to value pumped storage hydropower projects. Their efforts resulted in DOE publication of the Pumped Storage Hydropower Valuation Guidebook: A Cost-Benefit and Decision Analysis Valuation Framework. The guide provides an objective, transparent valuation methodology and helps measure both monetary and non-monetary value streams.

GREEN ENERGY TECHNOLOGY

As Earth Day approaches, a promising startup that grew out of University of Delaware research is on the cusp of making sustainable green hydrogen a reality. Versogen, a UD spinoff company led by Professor Yushan Yan, is one of three startups selected for the fourth cohort of the Shell GameChanger Accelerator (GCxN) program.

Cybersecurity in the Blue Economy

More than two-thirds of the Earth’s surface is covered by the oceans and seas. Over the next decade, these vast waters are expected to add $3 trillion to the global economy by generating electricity using marine renewable energy (MRE) devices. These “blue economy” technologies harness power across waves, tides, and currents that could reduce the carbon footprint from energy production and provide grid stability to remote coastal communities.

Shining, Colored LED Lighting on Microalgae for Next-Generation Biofuel

2 months ago sarah Jonas

As biofuels continue to present challenges, microalgae are gaining momentum as a biofuel energy crop. In the Journal of Renewable and Sustainable Energy, researchers show how a combination of monochromatic red and blue LED illumination on one type of microalga can enhance its growth and increase the biosynthesis of critical components, such as lipids, for microalgae feedstock development. The researchers focused on Dunaliella salina, typically extracted from sea salt fields and found in salt lakes.

Green fuels for aviation

Researchers at the Paul Scherrer Institute PSI and the partner institute Empa have started a joint initiative called SynFuels. The goal is to develop a process for producing kerosene from renewable resources. In this way liquid fuel mixtures of the highest quality, which would allow the most residue-free combustion possible and thus be suitable for aircraft propulsion, should be obtainable using carbon dioxide and hydrogen from renewable resources.

Low-Level Jets Create Winds of Change for Turbines

3 months ago sarah Jonas

Global wind power capacity has increased more than fivefold over the past decade, leading to larger turbines, but low-level jets are one cause for concern. The effects of these strong, energetic wind flows depend on how high the wind flows are in relation to the turbines. In the Journal of Renewable and Sustainable Energy, researchers considered three different scenarios in which the LLJs were above, below, and in the middle of the turbine rotors.

Wind Power off the Oregon Coast Could Provide More than Electricity

5 months ago sarah Jonas

A recent study found that 2 to 3 gigawatts of electricity from winds off the coast of Oregon could be carried by current transmission lines. That’s enough to power up to 1 million homes—a significant number since there are 1.5 million homes in Oregon. But just as significantly, it also means that delivering that power would not require much additional investment in new transmission infrastructure.

Climate Change Impact on Green Energy Production

9 months ago sarah Jonas

As the climate of the planet is changing, many researchers are looking to more renewable energy sources. In the Journal of Sustainable and Renewable Energy, researchers investigate whether the power generated by solar and wind farms would differ between current and future climates. The researchers focused on sites in Australia where variable renewable generators are located or are likely to be located in the future based on the Australian Energy Market Operator’s system plan.
