ARPA-E funds research on, and the development of, transformative science and technology solutions to address the energy and environmental missions of the Department. The agency focuses on technologies that can be meaningfully advanced with a modest investment over a defined period of time in order to catalyze the translation from scientific discovery to early-stage technology.
For the latest news and information about ARPA-E, its programs and the research projects currently supported, see: http://arpa-e. energy. gov/.
ARPA-E funds transformational research. Existing energy technologies generally progress on established “learning curves” where refinements to a technology and the economies of scale that accrue as manufacturing and distribution develop drive improvements to the cost/performance metric in a gradual fashion.
This continual improvement of a technology is important to its increased commercial deployment and is appropriately the focus of the private sector or the applied technology offices within DOE. In contrast, ARPA-E supports transformative research that has the potential to create fundamentally new learning curves. ARPA-E technology projects typically start with cost/performance estimates well above the level of an incumbent technology.
Given the high risk inherent in these projects, many will fail to progress, but some may succeed in generating a new learning curve with a projected cost/performance metric that is significantly better than that of the incumbent technology. ARPA-E will provide support at the highest funding level only for submissions with significant technology risk, aggressive timetables, and careful management and mitigation of the associated risks.
ARPA-E funds technology with the potential to be disruptive in the marketplace. The mere creation of a new learning curve does not ensure market penetration. Rather, the ultimate value of a technology is determined by the marketplace, and impactful technologies ultimately become disruptive – that is, they are widely adopted and displace existing technologies from the marketplace or create entirely new markets.
ARPA-E understands that definitive proof of market disruption takes time, particularly for energy technologies. Therefore, ARPA-E funds the development of technologies that, if technically successful, have clear disruptive potential, e.g., by demonstrating capability for manufacturing at competitive cost and deployment at scale. ARPA-E funds applied research and development (R&D).
The Office of Management and Budget defines “applied research” as an “original investigation undertaken in order to acquire new knowledge…directed primarily towards a specific practical aim or objective” and defines “experimental development” as “creative and systematic work, drawing on knowledge gained from research and practical experience, which is directed at producing new products or processes or improving existing products or processes.
” ARPA-E encourages submissions stemming from ideas that still require proof-of-concept R&D efforts as well as those for which some proof-of-concept demonstration already exists. Submissions can propose a project with the end deliverable being an extremely creative, but partial solution.
The Stimulate Utilization of Plentiful Energy in Rocks through High-temperature Original Technologies (SUPERHOT) program aims to boost baseload power supply by enabling future power production from superhot geothermal resources, defined as temperatures greater than 375 °C and pressures greater than 22 megapascals (MPa).
As the demand for power in the U.S. increases, driven by the rise in data centers and increasing electrification, superhot geothermal power can play an important role in addressing this critical need. The amount of energy in the Earth’s subsurface is immense, with estimates of at least 15,000 gigawatts (GW) of producible electricity from depths of at most 10 kilometers (km) within the U.S. alone.
Unfortunately, access to this resource has been constrained by the limited extent of natural hydrothermal systems, which currently only provide about 4 GW of utility-scale power. Expansion beyond natural hydrothermal systems is now possible by recent advances in Enhanced Geothermal Systems (EGS) and in Advanced Geothermal Systems (AGS), which essentially create artificial geothermal reservoirs.
The combination of highly productive superhot wells with the expanded geographic availability provided by EGS or AGS technology can accelerate the widespread development of gigawatt-scale geothermal facilities across much of the U.S., with the possibility of 10-20 GW of baseload power with a levelized cost of electricity (LCOE) less than $30 per megawatt hour (MWh) by 2040.
The goal of the SUPERHOT program is to support research and development of new technologies to enable scalable superhot geothermal by addressing the major technical challenges affecting geothermal well life and the ability to harvest subsurface energy effectively. Consequently, the focus is on the following subject areas: 1) robust well construction, and 2) transfer of heat from the surrounding geologic formation to the well.
