UI/UX Case Study

NexantECA

Providing technical, commercial, and economic analysis for the energy, chemical, and sustainable fuels industries.

Problem Statement

The old NexantECA website presented valuable research and consultancy services but suffered from poor navigation, inconsistent branding, an outdated visual identity and was highly cluttered. Stakeholder surveys revealed key frustrations:

Difficulty prioritising user journeys due to cumbersome content
Lack of clear messaging for diverse audiences
Visual design that did not reflect NexantECA's position as a global energy leader.

The challenge was to declutter and modernise the platform in a way that clarified the site's complex information hierarchy, to align with strategic and brand goals, and deliver an improved experience for multiple user groups, from energy consultants to corporate clients.

Basic Brand Refresh

Brand Imagery

We created a visual style called ‘eco-futurism’ inspired by science and sustainability. We used AI and photo compositing methods to blend images of terrariums, rainforests, molecular structures, solar panels, hardware, software, and other machinery. This unique and striking style with a slightly sci-fi futuristic feel symbolises the the brand’s shift into the future, becoming a forerunner in the field of truly sustainable energy.
