Amsterdam-based startup <\/span>Moonwatt<\/b> has recently raised <\/span>\u20ac8 million<\/b> to develop energy storage systems (<\/span>ESS<\/b>) using <\/span>sodium-ion technology<\/b>.<\/span><\/p>\n

The rapid growth of <\/span>renewable energy<\/b> over the past decade has increased the need for <\/span>higher\u2011performance<\/b> storage solutions. Although <\/span>lithium-ion (Li-ion)<\/b> technology still dominates the market, sodium-ion is emerging as a promising alternative, especially for projects where <\/span>cost is critical<\/b>. Founded in September 2024, Moonwatt aims to make <\/span>clean energy competitive<\/b> and available around the clock by compensating for the <\/span>intermittent output<\/b> of renewable sources. Its founders \u2013 <\/span>Zukui Hu<\/b> (CEO), <\/span>Guillaume Mancini<\/b> (CTO) and <\/span>Valentin Rota<\/b> (Sales Director) \u2013 previously worked together at <\/span>Tesla Energy<\/b>.<\/span><\/p>\n

Why choose sodium?<\/strong><\/h2>\n

Whether semi\u2011solid or solid\u2011state, <\/span>sodium-ion<\/b> batteries are gaining ground over lithium\u2011ion thanks to their <\/span>improved safety<\/b>, <\/span>energy density<\/b> and <\/span>production cost<\/b> advantages.<\/span>
\n<\/span> \u201cEach technology has its strengths and weaknesses. For example, <\/span>lithium iron phosphate (LFP)<\/b> has overtaken <\/span>nickel manganese cobalt (NMC)<\/b> in stationary storage because it is cheaper and more durable,\u201d explains Valentin Rota.<\/span><\/p>\n

Despite their <\/span>lower energy density<\/b> (140\u2013160 Wh\/kg), sodium\u2011ion batteries are perfectly suited to ESS where <\/span>space<\/b> is not a major constraint. Their <\/span>safety profile<\/b>, comparable to or even better than LFP, reduces the risk of fire. Their <\/span>service life<\/b> \u2013 1 to 1.3 cycles per day over 20 years \u2013 matches the needs of <\/span>solar power plants<\/b> very well.<\/span><\/p>\n

The strategic alliance between solar and storage<\/strong><\/h2>\n

Global <\/span>solar capacity<\/b> is expected to increase tenfold by 2030. <\/span>Combining solar with storage<\/b> has become essential to prevent <\/span>grid overload<\/b> and maximise the profitability of installations. Moonwatt designs <\/span>decentralised low\u2011voltage DC ESS<\/b> that are directly integrated into solar PV farms, reducing <\/span>infrastructure costs<\/b> and improving <\/span>energy efficiency<\/b>.<\/span><\/p>\n

Unlike <\/span>standardised containers<\/b>, their <\/span>modular<\/b> architecture can be scaled to projects ranging from a few hundred kW to several GW. \u201cWe are targeting <\/span>independent power producers and grid operators in Europe and worldwide, focusing on new installations and the upgrade of existing sites,\u201d Rota says.<\/strong><\/span><\/p>\n

Challenges and outlook for sodium\u2011ion<\/strong><\/h2>\n

While sodium is <\/span>abundant<\/b> and inexpensive, the <\/span>ongoing decline<\/b> in lithium prices remains a hurdle. \u201cThe sodium\u2011ion supply chain is still young, but as it matures it will help <\/span>stabilise costs<\/b> over the next few years. Some chemistries such as <\/span>NFPP (polyanions)<\/b> are particularly well suited to stationary storage,\u201d adds Rota.<\/span><\/p>\n

According to <\/span>Yole Intelligence<\/b>, the market will reach <\/span>40 GWh<\/b> by 2029, but Moonwatt is expecting <\/span>faster adoption<\/b>. Currently in the <\/span>prototyping phase<\/b>, the startup is planning <\/span>pilot projects<\/b> within a year and is aiming for <\/span>commercial production (>1 GWh\/year)<\/b> by 2027.<\/span><\/p>\n

Ambitions and development<\/strong><\/h2>\n

Moonwatt currently has <\/span>seven employees<\/b> and is actively recruiting to strengthen its technical team. Although no European research project has yet been launched, the company hopes to <\/span>work with the local ecosystem<\/b> to accelerate its growth and innovation.<\/span><\/p>\n
