Frustrated by interconnection delays? Batchable computing provides a solution



Frustrated by interconnection delays? Batchable computing provides a solution

By Phillip Ng, VP of company growth, Soluna

Our energy grid is rigid. It was constructed a century in the past for a special nation and a special energy economic system. Integrating this method with new intermittent era has been difficult, to say the least. The result’s frequent instances of over-saturation of renewables, however nonetheless counting on carbon-producing property to unravel for on-peak demand.

Our lofty, essential aim to decarbonize the grid will solely be realized if we make renewable sources economically viable and modernize each grid and demand to the era profile of renewable energy.

On prime of renewable energy’s intermittent era, {solar} and wind, in contrast to fossil fuels, cannot yet be reliably stockpiled for later deployment.

The consequence: demand should turn into extra versatile to unravel this mismatch.

Provide exceeding demand means curtailment, aka wasted energy. In 2021, an estimated 14.9 TWh of in any other case viable renewable energy was curtailed. That is the equal of $610 million in misplaced income, or enough energy to power the city of Chicago for a year.

This drawback is compounding as renewables improve their market share of latest era. Moreover, until we are able to create extra versatile demand, marginal {solar} and wind energy won’t assist improve the web capability on the grid:

Penetration of wind is the X axis; Utility to the grid measured by capability credit score is the Y axis. As penetration will increase, marginal utility decreases. Supply: Lori Chook, M Milligan, and Debra Lew. 2013. Integrating Variable Renewable Energy: Challenges and Options. Technical Report. NREL.

Primarily based on our evaluation, IPP manufacturing information, we estimate that as much as 40% of energy generated by particular person {solar} and wind farms goes to waste. This creates a large financial pressure on these energy producers. It additionally prevents new tasks from being inbuilt areas which might be wealthy in wind and {solar} assets.

Batteries and transmission supply long-term options to curtailment, however should not adequate to sort out this problem for various causes:

  • Batteries are costly and depend on a provide chain of uncommon minerals that’s each bottlenecked and working dry. They’ve quick lifespans and are tough to get rid of responsibly.
  • Transmission updates are expensive, time-intensive, and hindered by a scarcity of a unified nationwide grid within the U.S.
  • Each applied sciences are nonetheless emergent, displaying vital promise for later use, however require growth and at the moment should not instantly deployable.

There’s a third possibility: batchable computing.

Batchable computing, or batch processing, is computing that may be processed in batches at a time, preferrred for giant information units of repetitive inputs that aren’t time-sensitive. The computational course of started for use on a mass scale within the late nineteenth century, when Herman Hollerith, future co-founder of IBM, invented a tabulating machine that utilized batch processing to rely census outcomes.

The fantastic thing about batchable computing is that it’s interruptible, permitting it to run off of the intermittent energy of renewables. Co-locating information facilities that run batchable computing with renewable energy vegetation creates a hedge for unbiased energy producers (IPPs) who’re in any other case promoting energy solely to the grid. When provide outpaces demand and the grid can’t soak up extra megawatts, IPPs within the Soluna community can promote their extra energy to the information middle.

This resolution has mitigated the issue of curtailment considerably.

Case Research: 150 MW Wind Farm

Soluna companions with IPPs to convey an built-in resolution that marries the targets of decarbonizing the grid and furthering essential computational advances. Soluna buys the energy that may in any other case go to waste from these IPPs and makes use of that energy to energy compact information facilities that run batchable computing.

At present, we function two websites in Kentucky: Project Marie and Project Sophie (for Marie Curie and Sophie Wilson — all of our websites are named after feminine scientists who left an indelible mark on historical past).

We not too long ago broke floor on our latest website in Texas, Project Dorothy (named after Dorothy Vaughan, a mathematician on the NASA program that despatched America’s first satellites into house).

Batchable computing is instantly deployable and scalable, providing an answer to curtailment that’s prepared now. To study extra, learn our white paper on mitigating curtailment and stabilizing the grid by way of batch computing.

DOE pledges $20 million to boost CdTe thin-film solar technology



DOE pledges $20 million to boost CdTe thin-film solar technology

The U.S. Division of Energy has launched the Cadmium Telluride Accelerator Consortium — a $20 million initiative designed to make cadmium telluride (CdTe) {solar} cells inexpensive, extra environment friendly and develop new markets for {solar} cell merchandise. The brand new consortium was introduced in Northwest Ohio, residence to CdTe powerhouse First {Solar} and newer entrant Toledo {Solar}.

“As {solar} continues its reign as one of many least expensive types of energy powering our properties and companies, we’re dedicated to a {solar} future that’s constructed by American employees,” mentioned U.S. Secretary of Energy Jennifer M. Granholm. “DOE is proud to associate with main {solar} researchers and corporations to chart the way forward for CdTe expertise, which presents an immense alternative for home producers to assist guarantee our nation’s safety whereas offering family-sustaining jobs.”

“To maneuver America ahead, we’d like an all-of-the-above technique that propels our energy independence, lowers prices, and creates good-paying jobs. Northern Ohio has already revolutionized the sphere of {solar} expertise,” mentioned U.S. Consultant Marcy Kaptur (OH-09). “Now, by this exceptional partnership between the U.S. Division of Energy, the College of Toledo, and First {Solar} – our area will develop into a hub of next-generation energy innovation that’s constructed proper right here at residence by Ohio’s employees.”

The brand new Cadmium Telluride Accelerator Consortium will work on continued price and effectivity enhancements that may make CdTe cheaper and extra environment friendly, and extra aggressive on the worldwide market. To attain these targets, the crew has a broad analysis plan that features CdTe doping methods, characterizing and exploring new CdTe contacting supplies, and work to allow a bifacial CdTe module that absorbs gentle from the back and front of the module. DOE’s Nationwide Renewable Energy Laboratory (NREL) will administer the consortium, whose leaders have been chosen by a aggressive solicitation NREL launched final 12 months. The consortium shall be led by the College of Toledo, First {Solar}, Colorado State College, Toledo {Solar} and Sivananthan Laboratories.

NREL will function a useful resource, help, and technical evaluation heart because the consortium develops a expertise roadmap, conducts analysis to fulfill targets set inside the roadmap, and often assesses the home CdTe provide chain for challenges and alternatives. The consortium goals to increase home CdTe photovoltaic materials and module manufacturing, help the home CdTe provide chain, and improve U.S. competitiveness.

DOE’s Solar Photovoltaics Supply Chain Review Report recognized CdTe as a chance for increasing home manufacturing of {solar} panels, as much as the restrict that CdTe materials availability permits, with little threat of being overtaken by low-cost international competitors.

The FY22 Solar Manufacturing Incubator funding alternative, introduced final month, will help initiatives that prepared new applied sciences and manufacturing processes for commercialization and exhibit options that may enhance home manufacturing of thin-film photovoltaics constructed from CdTe.
