Battolyser
DESCRIPTION: Battolyser is the world's first dualpurpose
energy solution with an integrated battery
and electrolyzer system. The Battolyser can store and
supply electricity as a battery and when fully charged, it
automatically starts functioning as an electrolyzer splitting
water into hydrogen and oxygen with a high efficiency of
over 85%. It uses non-noble metal nickel-iron electrodes
and is integrated with alkaline electrolysis technology
to provide improved performance, low cost, and high
uptime. It is robust and flexible and can thus arbitrage
between power and hydrogen availability and prices.
SPECIFICATIONS:
* Capacity: 0.5 - 1.0 MW(h)
* Stack power consumption: 45-50 kWh/kg,
4-4.5 kWh/Nm3 of H2
* Production rate: 10-20 kg/hr or 111-222 (Nm3/h)
* Hydrogen purity: client specific but 99.9+%
* Water content: client specific
* Oxygen content: client specific
* Water consumption rate: 100-200 kg/hr
* Electrolyte: KOH
* Ambient temperature: 40°C
* Delivery pressure: 30 barg
* Life expectancy: 15 years
* Footprint: 1-3 skids (12 x 3 x 2.5 m3)
ADVANTAGES/KEY FEATURES:
* Continuous operations and power vs hydrogen
price arbitrage due to full system flexibility (Battery
(dis-)charge range of 0-100% and continuous
hydrogen production when fully charged)
* Renewable power load following resulting in
no curtailments and green hydrogen eligible
for clean fuel credits
* Reduced power cost due to high efficiency
of 80-92% (HHV) and responsible use of
scarce green electrons
* Deployable at scale with use of abundant and
conflict free materials (nickel and iron)
* Effective use of resources due to synergy in
material use, power electronics, balance of
plant and footprint
* Long lifetime of 15 years without stack
replacements provided by durable combination
of alkaline electrolysis and nickel-iron battery
technology
* Lower battery cost, as nickel-iron battery has high
depth discharge without electrode degradation
and is overcharge (electrolysis) resistant
* Reduced downstream hydrogen compression
required due to elevated operational pressure
* Non-flammable water-based electrolyte
* Simple and cheap end-of-life recycling with no
hazardous materials involved
APPLICATIONS/INDUSTRIES SERVED:
* Unlocking flex value of grid constrained solar
and wind parks
* Managing merchant risk of large offshore wind
parks with efficient hydrogen production arbitrage
* Offering continuous hydrogen production solutions
for export (ammonia, petrochemicals, liquid
hydrogen) from large off grid solar and wind parks
* Producing onsite green hydrogen as chemical
feedstock for industrial customers
* Providing perennial green energy to off grid
applications and hard to electrify sectors
* Service sectors include - petrochemicals, refinery,
transportation, synthetic fuels, metals production,
renewable energy grid, chemical processes,
and feedback to grid power.
