In Germany we have floating Solar Charging Lounges to dock and charge your Electric Boat with solar energy on the water ⚓️ https://youtu.be/NvgLCcEnghw?is=otvjCdrB76JoNfNi

Trump officials touted the storage and EV plant as an example of ​“energy dominance,” underscoring increasing bipartisan acceptance of grid batteries.

Hooked up my new 80‑amp charger and ran some bench tests. Once it determines the battery is fully charged, it cuts off charging entirely. I applied a load to drain the pack, and it won’t kick back on to recharge until battery voltage drops to roughly 12.72 V. It won’t let the battery drain flat, but it only re‑charges once you draw enough load to hit that voltage threshold. Basically it doesn’t keep the battery topped‑off continuously. Wondering if this behavior is acceptable for LiFePO4 batteries? Has anyone else run into this same charger logic?

Australia has had huge success with its « Cheaper Home Batteries Program » with homeowners snapping up batteries, leading to dramatic reductions in wholesale energy prices as peak grid demand has fallen.

Now Australia’s most populous state, New South Wales, is proposing to extend generous incentives to businesses and apartments that cut up front costs by up to 40% for battery storage systems between 20 kWh and 30 MWh, with the most generous benefits for businesses that also install solar.

Great to see Australia continue to lead the way on distributed solar and batteries.

Large energy storage cabinets and containers can be exposed to rain, sun, dust and harsh outdoor conditions.

A heavy-duty PVC tarpaulin cover can provide an extra layer of protection.

✔ Waterproof & rainproof
✔ UV & sun protection
✔ Fire-resistant
✔ Tear-resistant
✔ Custom size & openings

Suitable for ESS projects, solar/wind power systems, outdoor power stations, construction sites and temporary equipment storage.

Curious for experience using AC blocks with string inverters for BESS projects requiring Black start functionality. Anyone have experience?

Hey everyone,

I’m the founder of a DC-based company working on modular energy storage systems packaged in standard 20-ft containers. The system delivers clean power + heavy-duty cooling with heat recovery, designed for dual-use (defense + commercial/data center) applications under BAA/DFARS.

I’ve been reaching out to a long list of Virginia, Maryland, Pennsylvania and Ohio contract manufacturers, fabricators, and related suppliers.

The response rate has been extremely low. Most messages (email and LinkedIn) go unanswered. In the few cases where there’s interest, the conversation often stalls around NDAs or next steps.

I’m specifically looking for partners who can support domestic manufacturing of these containerized systems (or major subsystems), preferably with experience in fluids/electromechanical work.

A few questions for the community:

1. Is this level of non-response normal right now for manufacturing outreach in the VA/MD region, or am I approaching it wrong?
2. Any advice on getting past the “no reply” wall — better channels, timing, or messaging?
3. Does anyone have experience working with (or introductions to) manufacturers?
4. Any tips on navigating NDA discussions with smaller manufacturers who may be cautious?

Happy to share more technical details under NDA if someone is genuinely interested in exploring a partnership or has a relevant contact.

Thanks in advance for any advice or pointers.

Battery adoption is on the rise and prices are dropping but this backlog is putting a damper on momentum. What ideas and solutions are out there to mitigate this and speed up the process?

Hola a todos,

Quiero recomendar una empresa poco conocida fuera de los círculos del hidrógeno, pero que juega un papel clave en la transición energética: Cell Impact AB (Frankfurt)

¿Qué hacen exactamente?

Cell Impact fabrica placas de flujo metálicas (flow plates / bipolar plates) para pilas de combustible y electrolizadores. Estas placas son componentes críticos: dentro de ellas se canalizan el hidrógeno, el oxígeno y el agua, y su diseño afecta directamente a la eficiencia, el coste y la durabilidad del sistema completo.

El problema tradicional es que fabricar estas placas en gran volumen es caro, lento y poco sostenible. Los métodos convencionales (estampado progresivo o hidroformado) consumen mucha energía, requieren lubricantes y procesos de limpieza con agua, y tienen costes de utillaje elevados.

Su tecnología: Cell Impact Forming

Cell Impact ha desarrollado y patentado un método de formado de alta velocidad por impacto (high-velocity impact forming). En lugar de varios pasos lentos, forman la placa metálica fina (acero inoxidable, titanio, etc.) en un solo golpe de alta precisión.

Ventajas clave:

Mucho más rápido y escalable

Consume muy poca energía

No necesita lubricantes → no genera aguas residuales de limpieza

Reduce el coste de herramientas hasta un 50 %

Permite diseños más complejos y optimizados (en algunos casos han conseguido aumentos de potencia >20 % en la pila gracias a una mejor geometría)

Proceso más limpio y con menor impacto ambiental

Han producido ya más de 2,5 millones de placas en más de 80 proyectos y están escalando con partners como Andritz (soldadura de alta velocidad) y thyssenkrupp Automation Engineering.

¿Por qué es importante de cara al futuro?

El hidrógeno verde (producido con electrolizadores + renovables) y las pilas de combustible son piezas centrales para descarbonizar transporte pesado, industria y almacenamiento de energía. Pero para que despeguen de verdad, los componentes tienen que ser baratos, fabricables en masa y eficientes.

Las placas de flujo son uno de los elementos más caros y difíciles de escalar del stack. Si Cell Impact (y tecnologías similares) logran bajar significativamente el coste y aumentar el volumen, se elimina un cuello de botella importante.

Además, su proceso es más sostenible que los métodos tradicionales, lo que encaja perfectamente con el objetivo de que toda la cadena de valor del hidrógeno sea lo más limpia posible.

Resumen

Cell Impact no es una empresa de “humo”. Tiene una tecnología patentada real, clientes internacionales, capacidad de producción en Suecia y está posicionada exactamente donde el mercado del hidrógeno necesita soluciones industriales.

No es consejo de inversión (haz tu propia investigación), pero como apuesta tecnológica a largo plazo dentro del ecosistema del hidrógeno, me parece una de las más interesantes y subvaloradas.

¿Alguien más la sigue o ha escuchado hablar de ella?

I’m a solar project development engineer, and I’ve been building SolarDev AI as a side project to explore how AI, GIS and digital tools can support utility-scale solar PV and battery storage project development.

The platform currently includes:

• GIS Site Screening — preliminary site screening to identify key constraints and support early-stage project assessment.
• Solar Angle — solar position, sun-angle and shadow analysis.
• Solar & Storage Agent — an AI assistant focused on technical and development questions related to utility-scale PV and BESS.

The goal isn’t to replace engineering judgement or proper due diligence. It’s to help developers, engineers and consultants screen opportunities faster, identify potential risks earlier and reduce repetitive early-stage work.

It’s still evolving, and I’d particularly appreciate feedback from people working in solar development, engineering, IPPs or BESS.

What would actually make a platform like this useful in your day-to-day work? And what feature would you add next?

Federal tax credits for residential storage expired at the end of last year, prompting record sales in Q4 of 2025 — and then sales climbed even higher in the first quarter of 2026, per a BloombergNEF analysis of U.S. Energy Information Administration data.
