Tying rooftop solar payments to climate and grid benefits makes sense in theory. But in the real world, it could get very messy.

SK invests in Fulcrum BioEnergy to accelerate production of low-carbon fuel from waste

Read the full story at Green Car Congress.

SK Inc., the strategic investment arm of South Korea’s SK Group, was part of a $50-million investment in Fulcrum BioEnergy, a US-based waste-to-fuels company. SK Inc. was joined in the investment with a Korean private equity fund.

Fulcrum produces biofuel on a commercial scale by chemically converting municipal solid waste (MSW) into transportation fuels. SK Inc. plans to enhance its Environmental, Social and Governance (ESG) portfolio with its investment in Fulcrum.

Biogas from America’s favorite meat: pollution solution or a prop for poultry?

Read the full story from the Food & Environment Reporting Network.

But in addition to producing 4 billion pounds of what the industry touts as the healthiest, most affordable, and climate-friendly meat, Delmarva also annually generates hundreds of thousands of tons of chicken waste, including manure, feathers, bones, and processing sludge. These dregs — which contain high levels of nitrogen and phosphorus — are often over-applied to farm fields and then run off into local waterways, including the Chesapeake Bay, where these nutrients contribute to low-oxygen conditions that kill fish and crabs.

Now, a solution modeled by dairy and swine operations may be in the offing as biogas companies vie to build anaerobic digesters on Delmarva. Inside these heated tanks, hungry microbes will consume poultry waste and emit a mix of gases rich in methane. This biogas will be scrubbed to remove impurities like hydrogen sulfide and ammonia. Rebranded by the industry as “renewable natural gas,” it will then be sold to energy companies including Chesapeake Utilities and British Petroleum, which will burn the methane to generate heat and electricity, or compress it and sell it as truck fuel.

Pathways to Residential Deep Energy Reductions and Decarbonization

Existing homes hold great potential for saving energy and reducing carbon emissions. To realize that potential, the United States must dramatically increase the adoption of deep retrofits (which produce energy savings of 40% or more). This study explored several strategies that can make deep retrofits more manageable and appealing to consumers. We analyzed deep retrofits coupled with electrification of space and water heating (with heat pumps) in common types of homes in the five major U.S. climate regions. We analyzed three retrofit scenarios (a one-time comprehensive retrofit and two staged retrofits) to compare project costs and energy, carbon, and bill savings over time. We also evaluated alternate measures that may reduce project costs and improve consumer appeal. Deep retrofit projects are expensive; we conducted a financial analysis to determine the level of upfront investment or incentives required to keep monthly payments manageable for most households. We find that staged retrofit options and expanded measure packages can increase program flexibility to better meet consumer needs and interests without sacrificing energy savings. These approaches—coupled with strong federal and efficiency program incentives—can also make the cost of decarbonization more manageable. Promising program designs and financing options are emerging to support these approaches.

Energy-efficient isn’t enough, so homes go ‘net zero’

The Future of Clean Hydrogen in the United States: Views from Industry, Market Innovators, and Investors is the first report in the series From Kilograms to Gigatons: Pathways for Hydrogen Market Formation in the United States that aims to develop a comprehensive analysis of policy opportunities for further hydrogen development in the United States. Based on over seventy interviews with leaders across the hydrogen value chain, this report details the current state of the hydrogen market in the United States.

Surveying the BECCS Landscape

Download the document.

This report is a systematic review of the literature to understand the key opportunities and challenges associated with bioenergy with carbon capture and storage (BECCS), a broad set of systems that integrate the use of energy derived from biomass with the capture and long-term storage of carbon. BECCS has received much attention due to its potential to remove greenhouse gas emissions from the atmosphere; however, there are uncertainties regarding BECCS pathways that may have adverse economic, social, and environmental impacts. While BECCS can potentially decarbonize numerous sectors, including agriculture, forestry, electricity, waste, and industry, BECCS deployment in practice has been limited, and the actual emissions reduction potential of a given project depends on the project’s exact configuration, given the varying technical potential of BECCS projects in different geographic regions. Additionally, both the opportunities and challenges for rural and environmental justice communities are underexplored.

World’s first carbon removal plant converting wood waste to hydrogen

Read the full story at Environment + Energy Leader.

Climatetech company Mote is establishing its first facility to convert wood waste into hydrogen fuel while capturing, utilizing, and sequestering carbon dioxide emissions resulting from its process. It’s estimated that more than 500 million metric tons of wood and agricultural waste are generated every year in the US, which today is either disposed of via natural decay, landfills, or open-air burn, all of which return carbon to the atmosphere. With the engineering work of their first facility underway, Mote expects to produce approximately seven million kilograms of carbon-negative hydrogen and remove 150,000 metric tons of CO2 from the air annually. Mote expects to start hydrogen production starting as soon as 2024.

Thyssenkrupp to supply shell with 200 MW electrolysis plant for green hydrogen hub in Netherlands

Read the full story from ESG Today.

thyssenkrupp Uhde Chlorine Engineers, a joint venture of industrial and technology conglomerate thyssenkrupp and Industrie De Nora announced an agreement to engineer and build a 200 MW electrolysis plant for Shell’s ‘Hydrogen Holland I’ green hydrogen project in the Netherlands.

Shell is currently working on plans to develop a large-scale hydrogen hub in the port of Rotterdam. The Hydrogen Holland I project will produce green hydrogen for industry and the transport sector, with electricity coming from offshore wind warm Hollandse Kust, in development approximately 18.5 kilometers off the Dutch coast.
