Plug Power shares plunge, 2024 as company admits it could run out of money.

Plug Power shares plunge, 2024 as company admits it could run out of money.

Plug Power alarmed investors with its third-quarter earnings showing a net loss of $283 million on just under $200 million in revenue. This rate of cash burn will become a focus for analysts.

The company’s shares reflect it, now down 95% from the highs a couple of years ago. Plug was a favorite of traders, shooting up from $4 to $65 in less than a year. Here is the description from the company’s website:

Plug Power Inc. is an American company engaged in the development of hydrogen fuel cell systems that replace conventional batteries in equipment and vehicles powered by electricity.”

The higher interest rate environment may challenge survival as the earnings report shows sizable cost overruns. The company attributes a significant portion to outages in the hydrogen network and unexpected downtimes. Plug also points out there may be more loss provisions to come.

Service accrual charge reflects higher near-term cost projections, which have been impacted by delay in roll out of certain reliability investments: In the third quarter of 2023, the Company has incurred a non-cash charge of $41.6 million…. The Company is continuing to monitor the current cost trends and hydrogen market dynamics. If these trends continue, the Company may have to record additional service loss provisions in future periods.

The company remains optimistic about the technology, pointing out that many issues are transitory. The problem remains: raising capital will be much more difficult as the entire renewable sector is under pressure across developed economies (namely the United States and Europe).

We believe this hydrogen supply challenge is a transitory issue, especially as we expect our Georgia and Tennessee facilities to produce at full capacity by year-end.

Companies will need to prove they can get to profitability and maintain it. A similar challenge for ag-tech start-ups and other ESG darlings that soared during the cheap money era.

Fossil fuels when no rain, sun or wind?

Where I live a lot of people at one point starting really promoting nuclear energy again. Maybe this was a global thing.

My country does not have any nuclear energy and is traditionally/culturally very much against it.

They admitted it would take too long to build, be expensive and that we don’t really have the skill. We also don’t have space, but 🤷‍♂️

But they kept saying ‘baseload’ because they thought nuclear could provide energy, when there was no wind, no hydro, no sun and no stored energy at all.

I really have no idea how often that would realistically happen (neither did the pro-nuclear side), but realistically couldn’t we just use fossil in these situations? Wouldn’t that be so marginal as to not do that much damage?

Nuclear Energy Weirdness?

Even though nuclear power plants are expensive compared to other sources, why hasn’t there been innovations to bring costs down? Dont you think nuclear power has been purposely orchestrated to be more expensive so the big fossil fuel companies keep on churning?

Also on another note, How much nuclear power plants would it take to power the US?

As part of an organizational management course at the University of Arizona, my team and I are conducting some research and interviewing Shell employees to understand what organizational management looks like at a major company!

If you are a current or former employee at Shell, we would really appreciate if you take a few minutes to answer the following survey

This link is a short ANONYMOUS 2-5min survey that would be used strictly for our team's educational purposes if you are open to filling it out.

Exploring Maintenance Challenges in Solar and Wind Energy: Insights Needed

Hey all! I’m currently embarking on a journey to better understand the world of maintenance in the renewable energy sector, specifically within solar and wind power operations.

As someone deeply passionate about technology and its potential to drive positive change, I’ve been working on developing a Computerized Maintenance Management System (CMMS) aimed at simplifying and streamlining maintenance processes. However, I’m well aware that the best solutions come from a deep understanding of the actual challenges faced by professionals in the field.

This is where I’m reaching out to this knowledgeable community for insights:

  1. Maintenance Challenges: For those of you involved in solar or wind energy, what are some of the most pressing maintenance challenges you face on a daily basis? Are there aspects of maintenance management that are particularly time-consuming or cumbersome?
  2. Technology Adoption: How open is the sector, particularly SMEs, to adopting technology solutions for maintenance management? Are there any specific reservations or challenges associated with this?
  3. CMMS Experience: Have any of you had experience with Computerized Maintenance Management Systems? If so, what has worked well, and what could have been better?
  4. Collaboration Opportunities: Lastly, if there’s anyone here who might be interested in discussing these challenges further or even considering trying out a new CMMS solution tailored to the renewable energy sector, I’d be eager to connect and learn from your experience. My primary goal is to develop a tool that genuinely adds value and addresses the unique needs of this industry.

I am here to listen, learn, and collaborate. Thank you so much for taking the time to read my post, and I look forward to connecting and chatting with you.

Seeking Guidance for a Successful Career in Wind Energy: Choosing the Right Modules and Skills

Hello, I hope everybody is doing well!

I'm currently enrolled in a master degree in engineering physics (renewable energies specialization) in Germany (I have a bachelor degree in mechanical engineering). I'm quite interested in the wind energy industry and research. I want to ask the experienced engineers and scientists about the current high-demanding skills and high-paying jobs in this field. I have a wide range of modules to choose from for this master; therefore, I want to choose well to have a good background for my career. Also, what do you advise me in general to excel in this career—what kind of things I should learn alone, skills, and online courses I should take? I will appreciate any advice from you guys. Aerodynamics, aerospace, and artificial intelligence are areas of interest for me. (But I don't have relevant work experience.)

I'll give you an idea of the modules available:

Smart Grid Management
Computational Fluid Dynamics
Wind Energy Physics, Data & Analysis
Future Power Supply Systems
Wind Resources and their Applications
Design of Wind Energy Systems
Control of Wind Turbines and Wind Farms
Wind Turbine Technology and Aerodynamics
Offshore Wind Energy
Wind Turbine Measurement Techniques
Probabilistic Methods in Wind Energy
Stochastic Processes
Optimization in modern Power Systems
Integration of Wind Power in the Power System
Advanced Wind Energy Meteorology
Deep Learning
Machine learning
Intelligent Systems
Energy Economics
Fluid Dynamics
Turbulent Flows
Planning and Development of Wind Farms
Physics of Sustainable Energy
Optimization and Data Fitting

Thanks in advance; I'm a bit lost here, so any advice will be beneficial!
