# Version 2.0.0 Changes

Renewable Fuels
- Included in the scope: "bioenergy with and without CCS conversion options for power, liquid fuels, and hydrogen."
- Added a citation (Rose 2020) as an example study that estimates a "cost-effective role for biopower, bioliquids, and bio-hydrogen with CCS."
- Rearranged and added items to Figure 16 (and Figure 4 in executive summary)—anticipated role of the LCRI in technology development for renewable fuels and bioenergy. The reworked "pushpin" figure now contains 11 items; previously, it contained 5 items.
Hydrocarbon-Based Processes
- No changes.
Electrolytic Processes
- Added cost target in the introduction: "In the summer of 2021, the U.S. Department of Energy announced a Hydrogen Shot challenge to reach $1 per kilogram of clean hydrogen in one decade."
- Added 3 key research questions:
  - "What are current vendor offerings and what are they developing for future products?"
  - "What is the expected electrolysis system lifetime and how do operational decision factors affect that lifetime?"
  - "What are the tradeoffs for understanding capital cost of the system, electricity cost, and capacity factor on the cost of hydrogen production?"
- Updated the strategies for Research Goal 2 to emphasize understanding the effects:
  - "Strategy 1: Reduce the cost of hydrogen by improving operations understanding and their effect on production cost"
  - "Strategy 2: Understand the effects of critical supply chain factors on the cost of hydrogen"
- Adjusted the placement of 2 items in Figure 20 (and Figure 6 in executive summary)—anticipated role of the LCRI in technology development for electrolytic processes:
  - "Alkaline electrolyzers" was moved from "participate" to between "participate" and "lead."
  - "Electrolysis/battery hybrid systems" was moved from "lead" to between "participate" and "lead."
Delivery and Storage
- Updated the introduction and clarified the objective: "The objective of the Delivery and Storage TSC is to determine the potential impact that AECs may have on the operations, codes, standards, and materials used for existing infrastructure, and whether that infrastructure can be safely retrofitted and repurposed or if new built-for-purpose infrastructure is required to safely meet future demand for AECs."
- Updated and rearranged most items in Figure 22 (and Figure 7 in executive summary)—anticipated role of the LCRI in technology development for delivery and storage. The reworked "pushpin" figure now contains 9 items; previously, it contained 11 items.
Power Generation
- Added a key research question: "What are the key technical challenges associated with the safety of deploying pure and blended fuel (for example, hydrogen with natural gas or hydrogen with ammonia) in power generation equipment such as turbines and RICE, given the significant benefits arising from the use of existing assets (for example, pipelines) while lowering GHG emissions in the near term?"
- Added Research Goal 4: "Lead efforts to assure safety of power generation equipment deploying pure and blended AEC fuels." A strategy and action are included, too.
- Updated items in Figure 23 (and Figure 8 in executive summary)—anticipated role of the LCRI in technology development for power generation:
  - Split "Multi-burner boilers using AECs" (participate) into "Coal boilers" (track) and "Industrial boilers" (participate).
  - Added "Safety of power generation equipment" (lead).
End-Use of Low-Carbon Resources
- Updated the introduction to emphasize customer preferences and costs: "Ultimately, customer preferences and costs will drive investment and adoption decisions that will define, in aggregate, the trajectory of economy-wide decarbonization. Therefore, assessing the viability of low-carbon pathways must include an analysis of decision-making processes by the end-users of energy regarding their energy requirements."
- Transportation
  - Included in the scope: "certain heavy-duty construction, agricultural, and mining equipment." And, added a statement that acknowledges "notable momentum in research and demonstration of AEC-fueled heavy-duty vehicles used in the construction, agricultural, and mining sectors."
  - Rearranged and updated Key Research Questions to emphasize economic feasibility, performance impacts, and total ownership costs.
  - Updated the strategies for each of the 3 Research Goals.
- Industry
  - Inserted clarifying phrases for Key Research Questions 5, 6, 7, and 8.
- Buildings
  - Updated the strategies for Research Goal 1.
Safety and Environmental Aspects
- Updated the "Water Usage and Consumption" example in the introduction.
- Added "Equity, Environmental, and Energy Justice" paragraph in the introduction.
- Updated the "2. Safety Training of Personnel" paragraph in the introduction by appending "and the Public" to the heading and adding this sentence: "In addition, clear communication of safe usage protocols will be needed for use of these fuels by the public, such as in the situation of vehicle fueling stations."
- Added "4. Enhancing Circularity of Low Carbon Technologies" paragraph in the introduction.
- Added "5. Atmospheric Impacts" paragraph in the introduction.
- Changed several words in Key Research Questions 7 and 9.
- Added Key Research Questions 10 and 11:
  - "How can low carbon technologies and fuels effectively integrate in circular economies to enhance environmental, social, and economic outcomes?"
  - "How should the deployment of new technologies be evaluated in terms of equity and environmental and energy justice?"
- For Research Goal 3, added Strategy 3: "Create Circular Economy Pathways for Low Carbon Technologies and Fuels" and included 2 actions.
- For Research Goal 4, updated Strategy 1 and its action; and added Strategy 2: "Support Equity, Environmental, and Energy Justice Goals" and included 1 action.
Integrated Energy System Analysis
- Changed the US-REGEN website link to https://us-regen-docs.epri.com.
- Included "synthetic hydrocarbons" in the list of new features being added to US-REGEN.
- Scenario Analysis:
  - Changed the date for the first release to 2022.
  - Updated the Scenarios Considered paragraph to emphasize that scenarios are designed "around key technology uncertainties."
  - Reference Scenario: replaced "no inclusion of advanced technologies" with "technology cost and performance improvements, including end-use efficiency."
  - Net-Zero by 2050 Scenario: clarified "endogenous adoption of technologies and pathways to achieve target at least cost."
  - Removed the Electric Sector Net-Zero by 2035 Scenario.
  - Technology Sensitivity Scenarios: updated and clarified each bullet point.
- Technology Cost and Performance Modeling:
  - Current Status: replaced the original "preliminary look at hydrogen production cost estimates" paragraph with a new paragraph that describes recently-completed cost and performance studies: 14 low-carbon technologies cost and performance; future cost pathways for electrolysis; and the development of a learning curve model.
  - Removed Figure 28 (example levelized cost of hydrogen production results from the cost and performance framework). Subsequent figures 29 through 33 were renumbered to 28 through 32.
