tCell™ energy block. Unshackle from the Grid!

The Grid is obsolete. Make your own now with tCell® and solar and produce electricity for much less than the Australian legacy electrical grid¹.
1 unit tCell® = 0.5kWh 220 x 209 x 142 mm , 10kg energy block. Available in 2.3V or 4.6V DC. It's Lego™ for electricity. Simply select quantity of tCell® for voltage and wattage required , stack and connect.


Features/Benefits:

o 25 year service life (or 20000 full cycles)
o High power for almost any requirement. Continuous usage (charge or discharge): 2.3V ➜ 200A, 4.6V ➜ 120A. Much higher 30min or once-per-day capability
o Maintenance free
o Works when cold
o 15 year warranty
o Retrofitting to replace lead acid batteries usually possible.
o Scalable, add more tCell® to your stack for up to 5 years after first. Minimises project risk.
o Simple and safe to ship and stack . Qualified electrician should connect to power conversion equipment (PCE).
o The safest lithium ion chemistry yet (lithium titanate)
o AS5139:2019 compliant. Site conditional.
o Free, one time, Homer Pro site energy simulation report for purchases > 10 x tCell®. Know your optimal energy plan and savings, in advance.
o 12V single tCell® unit also available for farm engine applications. Great upgrade for heavy duty starts, infrequent usage. 1000+CCA. Probably outlives your tractor. Same price. Not suitable for configuring into larger storage arrays.
o We also sell Victron PCE at attractive prices. Overseas orders / shipment possible. Contact us.

Homer Pro Case Study for typical residence at postcode 2800.

Grid only: Net Present Cost (NPC) = $150k, Initial investment (IC) = 0, LCOE= $0.70 kWh
Grid plus 5kW Solar PV (ie typical today) : NPC = $73K,IC = $8, LCOE = $0.34 / kWh
Optimal Solution Grid plus 27kW PV plus 15kWh tCell® (30 units) : NPC = $14k , IC = 44k, LCOE= $0.07 / kWh
Off-Grid option 12kW PV, 20kWh tCell® 5kW genset: NPC= $50K, IC= $44K, LCOE = $0.24 / kWh

Case study conclusions.. Optimal grid connected solution with tCell® is 80% less cost than typical solar installation today. Also off-grid now is competitive grid when using tCell®

(Case study assumptions: 23.3kWh/Day consumption residential load profile, Net present cost for 25 years in 2020 dollars. Grid costs rise at 5% per annum, 5kW export permitted, usage at $0.32 /kWh, export $0.10 /kWh, bank interest is 0.5%.)

Backstory.

The lithium titanate chemistry (LTO) used in tCell® was developed for the US Navy by Altairnano in the late 1990s. Due to cost and its slightly less energy density they were not able to fully commercialise it. Altairnano and their US patents were bought out by a major Chinese bus company (ZHYLE). LTO cycle life , huge throughput and cold performance make it perfect for heavy transport. They had the ability to mass produce it and reduce the cost. About 73% of all lithium ion battery chemical stocks originate in China. And within the lithium ion types we believe LTO variant is the only chemistry fit for the purpose of long term stationary storage. Strathmore Energy ABN 24 632 325 574 is pleased to now bring the technology to this market. We are 100% Australian owned and operated. And always will be.

Innovation from the Bush continues. First full street lighting : Tamworth 1888. Sydney was not till 16 years later. History may not repeat but it often rhymes.

The Question. The most important question you need to ask is what is the total cost of the system over its project life. This can either be as Net Present Cost (lump sum now) or LCOE (energy cost per kW). And to know this , when batteries are involved you must know the battery fade. All batteries fade. The key measure is how many cycles to 80% SOH ie how many 100% full discharge /charge cycles until the battery capacity is 80% of new capacity. This is the only way to compare batteries and your supplier should issue this in writing.. tCell® is 20000 such cycles. It is this that delivers low cost, long term energy in a solar energised , tCell® stored, micro grid.


¹.LCOE = Levelised Cost of Electricity (including capital cost) . For an Australian RET STC claimable solar installation that has been sized using Homer Pro simulation tool , installed with effective procurement and project management expected LCOE over 25 years of tCell® service life is $0.25. Excluding freight, any remote location penalty charges.
