Beyond lithium-ion batteries and pumped hydro, new stationary energy storage even provides faster charge-discharge and 6-month seasonal storage of solar. New gravity, air, hydrogen, thermal, supercapacitor and flywheel stationary storage are compared to emerging forms of battery including for smart cities. Beat mainstream lithium-ion on price and performance. Winners, losers, 20-year roadmaps, forecasts new multi-billion dollar businesses. Gaps in the market. At last, you can understand it all in the IDTechEx market research report "Stationary Energy Storage Without Batteries: Grid, Microgrid, UPS, Trackside 2021-2041".

Today, stationary energy storage usually means batteries or pumped hydro. They have environmental and scale-up issues from shortage of materials to shortage of sites. They poorly meet or fail completely with many of the emerging requirements, such as railway surges and seasonal storage of solar. That means a large market for alternatives.

 

Welcome the 195 page IDTechEx report, "Stationary Energy Storage Without Batteries: Grid, Microgrid, UPS, Trackside 2021-2041". Uniquely, it reveals how new battery-less stationary storage will surge to a $6.5 billion business in 2031, with much more beyond. Learn how compressing air or lifting weights can win for the developing market for massive seasonal storage of solar power but there are subsets and other options. Electric train systems taking over from diesel save 15% of their energy bill if 95% efficient supercapacitors grab train braking energy, then surge it into trains leaving. Batteries perform poorly for this, so they are being abandoned.

 

For electricity supply, see how there is scope for storing hydrogen for fuel cells, using flywheels, new lithium-ion supercapacitors, pseudocapacitors, thermal storage, liquifying or compressing air. These non-battery solutions, mostly with no precious metals, toxins or explosions are also compared and prospects appraised. Which are excellent and which are a poor investment for this? Many non-battery options are promised to reach half the levelized cost of storage of lithium-ion batteries, today's stationary-storage favourite. Which ones and can they be believed?

 

The report is commercially-oriented to serve all in the value chain by clarifying where the technology and demands are leading, the players and the gaps in the market. Good and bad: assessment not eulogy. It is researched and frequently updated by IDTechEx analysts worldwide, often at PhD level, and carrying out interviews in local languages. Many new infograms, pictures, diagrams, graphs and ongoing 2021 news items make it both easily readable and up-to-date.

 

 

The Executive Summary and Conclusions section is sufficient for those with limited time, its many new infograms and tables comparing the options, technologies, achievements and opportunities with many roadmaps and forecasts to 2041. They even reveal the later-arriving challenges and opportunities. See some mainstream battery uses being challenged by later-emerging cleaner, better-performing, safer, more affordable options covered in the report.

 

Understand ongoing battery problems leading to the adoption of alternatives for reasons of safety, performance, and cost. See the contestants for more affordable, better performing, safer and more environmental energy storage than batteries can provide. We introduce the electricity grid structure, the service which the grid requires and microgrids and give new storage examples from 2021.

Technology, success, best practice and potential for pure, symmetrical EDLC and derivatives lithium-ion capacitors LIC and pseudocapacitors in banks 1kWh and above, including multipurpose backup/ peak shaving/ power factor correction etc. Manufacturers compared.

35 packed pages because of its importance and variety including U-PHES ARGES, MGES etc. In the initial part, a chart of the energy provided by a mass of different size and falling from different heights is provided to give the reader a feeling of the size of the mass required. The subchapter concludes with an analysis of GES and its capability to reach the market.
