Maritime Industry Briefing: Energy Technology Developments with Potential Marine Applications

## Maritime Industry Briefing: Energy Technology Developments *10 June 2026* While this week's broader energy news cycle was dominated by developments outside the core shipping sector, two announcements from the power electronics and energy storage industries merit attention from maritime professionals tracking the ongoing electrification of vessels and port infrastructure. ### ROHM Advances SiC MOSFET Packaging for High-Power Applications Kyoto-based semiconductor manufacturer ROHM Co., Ltd. has unveiled the TSC3PAK package for silicon carbide (SiC) MOSFETs, a development that could have downstream relevance for marine power conversion systems. The new package — measuring 14.00 x 18.58 x 3.50 mm — employs a top-side heat dissipation structure, positioning the heat dissipation surface on the upper face of the component to enable more efficient thermal management in high-voltage applications. According to PR Newswire, the design supports automated assembly processes, a factor that could reduce manufacturing costs for the variable-speed drives, inverters, and power conversion units increasingly found aboard hybrid and fully electric vessels. SiC-based power electronics are gaining traction in marine propulsion and shore power systems due to their superior efficiency at high switching frequencies compared with conventional silicon devices. ### EVE Energy Reports 67 GWh in Orders at SNEC 2026 Chinese battery manufacturer EVE Energy reported securing orders exceeding 67 GWh at the SNEC PV Power Expo held in Shanghai from 3 to 5 June 2026. The company showcased its full energy storage portfolio, including the 'Mr. Big Family' series, underscoring its ambitions in large-scale stationary energy storage — a segment with growing relevance to port microgrids, cold-ironing infrastructure, and shore-side power systems that support vessels at berth. The scale of orders reported by EVE Energy reflects continued strong demand for grid-scale battery storage, a technology that port authorities and terminal operators are increasingly evaluating as part of decarbonisation strategies and energy resilience planning. --- *Note: Neither announcement was issued directly by maritime industry sources.
