Oil Wells that End Well
In briefAI summary — tap to read
Kemp Gregory, CEO of Renewal Energy, presents a solution to convert idle oil and gas wells into gravity-based energy storage systems that simultaneously address well cleanup liabilities and renewable energy storage challenges. The technology uses mechanical weight-and-pulley systems to store and release energy, offering lower costs and longer duration than lithium-ion batteries while preventing methane leaks and enabling flexible grid support.
Key takeaways
- The U.S. has 2.6 million idle oil and gas wells that represent a $182 billion cleanup liability and methane emission risk; Renewal converts these into energy storage infrastructure instead.
- Gravity-based energy storage uses repurposed wells and mechanical systems rather than batteries, achieving 74% round-trip efficiency with zero degradation and net-negative CO2 impact by preventing methane leaks.
- The technology uniquely enables variable-duration storage from one hour to 100+ hours by clustering multiple wells operating in parallel or sequence, matching unpredictable renewable energy supply patterns.
- California represents the optimal market due to consolidated well ownership (65% held by three companies), high plug-and-abandonment costs, strong energy storage demand, and supportive regulatory environment.
- Renewal has raised $6.2 million in 2022 through ARPA-E grants ($2.7M), Department of Energy funding, and seed investment to develop and deploy pilot systems.
About Kemp GregoryKemp Gregory is CEO and co-founder of Renewal Energy. He holds a mechanical engineering degree from UT Austin, worked as a completions engineer for Shell in the U.S., Canada, and Argentina, and earned a master's in civil environmental engineering from Stanford where he developed this gravity-based energy storage concept.

Message from our president
Dear fellow members,
As we welcome the month of March, we also acknowledge the monthly theme of "Water and Sanitation." Access to clean water and proper sanitation is a basic human right and a crucial factor in promoting good health and preventing the spread of diseases. As Rotarians, we understand the importance of this issue and continue to strive towards ensuring that everyone has access to these basic necessities.
However, we cannot ignore the fact that another crisis is affecting our communities - the mental health crisis. With the COVID-19 pandemic, many people have lost loved ones, had their social networks disrupted, and faced other struggles that have taken a toll on their mental well-being. Unfortunately, the stigma surrounding mental health issues often prevents people from seeking the help they need.
As we move forward with our year's focus on healthcare, let us not forget the importance of promoting awareness in this important area. I was particularly pleased to see that Rotary International President-elect R. Gordon R. McInally will focus on mental health during his term. In alignment with his goals, we can already start addressing mental health by providing resources and information on mental health, hosting programs on mental health, and creating a supportive and inclusive community where members feel comfortable discussing their mental health and seeking support if needed. We as Rotarians can play a crucial role in offering hope to those who are struggling with mental health challenges. We can help break down the barriers that prevent people from seeking help by raising awareness and providing support.
Let us work together to positively impact the lives of those affected by mental health challenges and healthcare issues in general, both within our E-club and beyond.
Yours in Service,
Angelica Marotta, PhD
President 2022-2023 Rotary eClub of Silicon Valley
Rotary International District 5170
Weekly Funny with Shags
We believe laughter is an important part of life, and we should all make time to laugh a little. This segment of our meeting is meant to tickle you just enough. These funnies are curated by member Steven "Shags" Shagrin!
Can You Talk?
At the doctor's waiting room a man was sitting opposite a mother and her little daughter.
He asks the little girl, "Hi there, and how old are you?"
The little girl showed him 4 fingers to indicate she is 4 years old.
The man says, "That is nice, but can't you talk?"
The little girl replies, "Yes I can, but can't you count?"
Inspiration
Every week we share a short video highlighting innovation, education, entrepreneurship, or whatever we think might inspire you to see the world in new ways.
In the realm of cluster ballooning, Jonathan Trappe is a big deal. In this short piece, you'll about both.

Project Opportunity
Charter member Keith Marsh is organizing a Rotary project to Project Amigo in October for the “Day of the Dead” (Dia de los Muertos). The week-long trip to Cofradia, Mexico will include Rotary Service in the areas of International Service, Youth Service and Fellowship. It will also include cultural and travel photography of the festivities surrounding Day of the Dead. Space is limited.

Happy Dollars: do good by sharing something good
Each week we ask our members to share stories with the club and toss in a few dollars to support our efforts. The primary goal of this section is to provide a fun way of getting to know each fellow members and guests, while giving back to a good cause.
Happy dollars is an opportunity to share something positive that has happened in your life whether it is personal or business. Think of it as your opportunity to brag a little, but also put a little bit into a karma jar. The money donated through happy dollars is put to charitable use, and the message that you leave for happy dollars will be posted in our online meeting the following week for the entire week for folks to see! (Pending that it’s appropriate!)
Here are the happy dollars contributions from last week!
This section is usually updated in the early hours of Saturday, so contributions made over the weekend may not be listed here.
Rory Olsen made a $20 donation.
I had an interesting week. The weather was unseasonably warm. Great week.
Kelly Ku made a donation.

This week's speaker, Kemp Gregory, is the CEO and a co-founder at Renewell Energy. His personal career is a forerunner of the larger energy transition required to decarbonize the electrical grid. Prior to Renewell Energy, Kemp worked for Shell for five years, where he installed cutting-edge downhole technology, managed capital-intensive projects, and coordinated large operations teams across North and South America.
Renewell’s patented technology stems from a simple idea: use pre-existing wells and the power of gravity to store and generate electricity. In times of need, potential energy in our system can be captured by lowering a weight down the well, producing energy by turning a regenerative winch. The weight can remain near the bottom of the well until it makes economic sense to buy energy to lift the weight back to its starting point, thereby ‘charging’ the system. The Gravity Well system is unique among all other energy storage technologies in that, on average, each system will have a net-negative carbon footprint because idle wells are often leaking methane.
Members and guests, please welcome Kemp Gregory!
