Scientists from the National Renewable Energy Laboratory (NREL) have developed a simple way to better evaluate the potential of novel materials to store or release heat on demand in your home, office, or other building in a way that more efficiently manages the building s energy use.
Their work, featured in
Nature Energy, proposes a new design method that could make the process of heating and cooling buildings more manageable, less expensive, more efficient, and better prepared to flexibly manage power from renewable energy sources that do not always deliver energy when it is most needed.
The paper, Rate Capability and Ragone Plots for Phase Change Thermal Energy Storage, was authored by NREL s Jason Woods, along with co-authors Allison Mahvi, Anurag Goyal, Eric Kozubal, Wale Odukomaiya, and Roderick Jackson. The paper describes a new way of optimizing thermal storage devices that mirrors an idea used for batteries, helping to inform what new thermal storage materials

Researchers developing renewable plastics and exploring new processes for plastics upcycling and recycling technologies will now be able to easily baseline their efforts to current manufacturing practices to understand if their efforts will save energy and reduce greenhouse gas emissions.
Benchmark data calculated and compiled at the National Renewable Energy Laboratory (NREL) provide a measurement at the supply chain level of how much energy is required and the amount of greenhouse gases emitted from the production of a variety of plastics in the United States. Today, we employ a predominantly linear economy for many of the materials we use, including plastics, said Gregg Beckham, a senior research fellow at NREL. Many people and organizations around the world are looking at ways to make our materials economy circular.

NREL researcher Alli Werner prepares an experiment to evaluate the ability of engineered
P. putida bacteria (in the flasks) to degrade polymeric plastics, such as polyethylene terephthalate (PET). NREL s goal, in collaboration with industry, university, and government laboratory partners, is to use bio-based methods to convert these plastics into monomers that can be upcycled into high-value plastics once again creating a circular plastics economy.
