On June 2, 2021, the U.S. Department of Energy’s (DOE) Office of Energy Efficiency & Renewable Energy (EERE) announced that the United States, Denmark, and Norway joined forces with the Global Maritime Forum and the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping to lead a new Zero-Emission Shipping Mission. This effort is part of Mission Innovation, “a global initiative to catalyze action and investment in research, development and demonstration to make clean energy affordable, attractive and accessible to all this decade.” Supported by the governments of India, Morocco, the United Kingdom, Singapore, France, Ghana, and South Korea, Mission Innovation aims to accelerate the Paris Agreement progress toward net zero emissions. According to DOE’s EERE, international maritime shipping represents approximately two to three percent of the world’s total annual greenhouse gas (GHG) emissions. Without addressing these emissions from maritime shipping, emissions could increase anywhere between 50 and 250 percent by 2050. Therefore, the Zero-Emissions Shipping Mission aims to:

  • Develop, demonstrate, and deploy zero-emissions fuels, ships, and fuel infrastructure across the value chain;
  • Ensure that by 2030, ships capable of running on hydrogen-based zero-emission fuels, such as green hydrogen, green ammonia, green methanol, and biofuels, make up at least five percent of the global deep-sea fleet measured by fuel consumption; and
  • Ensure that by 2030, at least 200 of these zero-emission fueled ships are in service and using these fuels across their main deep-sea shipping routes.

On June 7, 2021, Secretary of Energy Jennifer M. Granholm launched the U.S. Department of Energy’s (DOE) Energy Earthshots Initiative. Designed to accelerate innovation of abundant, affordable, and reliable clean energy solutions within the next ten years. Secretary Granholm stated that the first Energy Earthshot will be the Hydrogen Shot, which sets an ambitious yet achievable cost target to accelerate innovations and spur demand of clean hydrogen.” The Hydrogen Shot aims to reduce the cost of clean hydrogen by 80 percent to $1 per kilogram (kg) while also creating more clean energy jobs. Currently, clean hydrogen costs approximately $5 per kg. This initiative will drive program development across DOE’s science and applied energy offices, and the Advanced Research Projects Agency-Energy (ARPA-E).
DOE’s Hydrogen Program issued a Request for Information (RFI) on viable hydrogen demonstrations that can help to lower the cost of hydrogen, reduce carbon emissions, create jobs, and provide benefits to disadvantaged communities. Topics for the RFI include:

  • Hydrogen Production, Resources, and Infrastructure;
  • End Users for Hydrogen Based on Specific Regions, Cost, and Value Propositions;
  • Greenhouse Gas and Other Pollutant Emissions Reduction Potential;
  • Diversity, Equity, and Inclusion (DEI), Jobs, and Environmental Justice; and
  • Science and Innovation Needs and Challenges.

RFI responses are due on July 7, 2021, by 5:00 p.m. (EDT). Additional information about the RFI is available here.

On May 4, 2021, the U.S. Department of Energy’s (DOE) Argonne National Laboratory published an article titled “Retrospective Analysis of the U.S. Corn Ethanol Industry for 2005-2019: Implications for Greenhouse Gas Emission Reductions.” Using a life-cycle analysis (LCA), researchers at the Argonne National Laboratory quantified the life cycle of greenhouse gas (GHG) emissions of fuels to compare relative GHG impacts among different fuel production pathways. According to the retrospective analysis conducted, since 2000, corn ethanol production in the United States quadrupled due to supportive biofuels policies such as the U.S. Environmental Protection Agency’s (EPA) Renewable Fuel Standard (RFS). Consequently, carbon intensity (CI) over the past 15 years has significantly decreased by 23 percent. Since 2000, the corn ethanol production pathway, including corn farming and biorefineries, has substantially evolved. Researchers state in the article that this shift into more efficient farming and biorefinery practices increases revenue while also potentially reducing the emission burdens of ethanol production. DOE’s Argonne National Laboratory researchers conclude that biofuels, including corn ethanol, can and likely will play a key role in decarbonizing the U.S. economy.
The article’s findings will also be used by DOE to update key corn ethanol parameters in the Argonne National Laboratory’s Greenhouse Gases, Regulated Emissions, and Energy Use in Technologies (GREET) Model 2021, which will be released in October 2021.

On May 25, 2021, the U.S. Department of Energy (DOE) announced the availability of up to $14.5 million in investments for research and development (R&D) to reduce waste and energy use related to the recycling of single-use plastics. As the largest subset of plastics found in landfills, single-use plastics, including plastic bags, wraps, and films, are also among the most challenging to recycle. According to DOE, plastic production uses the same amount of oil around the world as the aviation industry. Only ten percent of plastics, however, are currently recycled, and most of those plastics are downcycled, or repurposed into low-value products. DOE Secretary of Energy, Jennifer M. Granholm, hopes that these funds supporting plastic recycling innovation will be a “triple win by cutting plastic waste we see in our everyday lives, reducing industrial energy use and resulting emissions, and creating clean manufacturing jobs for American workers.” This is an effort by DOE to decarbonize the plastics industry and increase investments in recycling processes. There are many obstacles to plastic film recycling, including collection, sorting, contamination, and lack of economically viable methods for recycling and upcycling. Therefore, DOE will support various projects to develop viable solutions for converting plastic films to more valuable materials and designing plastics that are more recyclable and biodegradable.

In addition to a concept paper and full application, the application process requires a description of how diversity, equity, and inclusion objectives will be incorporated into the project. Submission deadlines are as follows:

  • Concept Paper – Deadline: June 28, 2021, by 5:00 p.m. (EDT);
  • Full Application – Deadline: August 16, 2021, by 5:00 p.m. (EDT); and
  • View Full Application Reviewer Comments – Between September 23, 2021, and September 28, 2021, by 5:00 p.m. (EDT).

On April 28, 2021, University of York researchers announced the discovery of a new enzyme derived from a fungus called Parascedosporium putredinis NO1, that can act as a catalyst for a biochemical reaction that breaks down forestry and agricultural waste.  The research was done in collaboration with DOE’s Great Lakes Bioenergy Research Center and the University of Wisconsin.  This development, according to the University of York, could play a key part in upscaling renewable fuels and chemicals.  Professor Neil Bruce explained that this discovery is a breakthrough because, currently, there are no industrial biocatalytic processes for breaking down lignin, which is present in lignocellulose.  This enzyme, however, can break through the lignin to begin the degradation process needed to produce biofuels.  Professor Bruce elaborated that the “treatments with this enzyme can increase the digestibility of lignocellulosic biomass, offering the possibility of producing a valuable product from lignin while decreasing processing costs.”
