Renewables and Energy Storage
In 2019, renewable energy production has not yet met the mainstream milestone of 24/7 availability. That said, the social attitudes, local policies, and consumer awareness are in place to push this imperative forward with the urgency that it requires. Across the globe, there needs to be a focused and disciplined mandate to address climate change, pollution, and the unreliability of energy grids.
Natural disasters (e.g. loss of power from hurricanes, earthquakes, snow storms) and ‘wildfire prevention’ power outages (called PSPS for public safety power shutdown) imposed by utility companies in California has resulted in an increasingly unreliable energy grid:
- Highly efficient residential and commercial energy storage systems (ESS) using GaN technology will enable distribution, local storage, and on-demand access to renewable energy. Both cost reduction and increasing energy security demands will drive this.
- With the price of ESS dropping and increased residential and commercial interest, sales of ESS will continue to rise, particularly in states such as California and Texas.
- Smaller ‘all-in-one’ products such as solar panels with solar inverter and battery storage built in will provides AC power 24/7 if the local power grid goes down. GaN’s efficiency in power conversion (lighter weight and smaller ESS) will be a key component to enable this kind of product design.
- The movement from lead acid to lithium ion batteries will lead to declining battery costs and the development of smaller, lightweight, energy-dense batteries that will pair with GaN technology-based converters and inverters to lead the revolution in ESS.
- Interest in local micro-grids for both business and residences will grow as individuals look to increase their energy security and leverage a collective of individuals ESSs.
